Standards & Tiers
ROOTED is not a list of recommended products — it's the trusted standard for evaluating them. Every category is judged against its own published standard before a single product in it is rated. Standards come first. Products come second.
The Tier System
Products sit in one of three tiers based on ROOTED's published standards. Every placement includes a written rationale. No pay-to-play. Ever.
TIER 1Rooted Approved
No meaningful compromises. Would confidently recommend to a family member.
- Meets all primary ROOTED standards
- Transparent sourcing and manufacturing
- Third-party certification confirmed
TIER 2Good Option
Minor compromises — documented clearly. Still recommended for most people.
- Meets most ROOTED standards
- One or two minor flags — always disclosed
TIER 3Budget / Transitional
Acceptable when cost limits better options. Not ideal long-term.
- Meets basic safety thresholds
- Notable compromises — clearly disclosed
The Rule
No brand can pay to improve their tier. If a brand reformulates, we update the rating with a date stamp. Tier assignments are living documents.
Category Standards
Every category is evaluated against its own published standard before any product in it is assigned a tier. Tap a category to see exactly what ROOTED looks for, what raises or lowers confidence, and how Tier 1/2/3 is defined specifically for that category.
Clothing sits directly against skin for hours at a stretch. ROOTED's core concern is material honesty — what a garment is actually made of and treated with — plus durability, since a shirt that lasts eight years beats three that last one year each.

What We're Optimizing For
- Natural, breathable fiber content
- Minimal, disclosed, non-toxic dye and finishing chemistry
- Durability and garment lifespan
- Manufacturing transparency
Green Flags
- Certified organic cotton, linen, hemp, or wool (GOTS, OEKO-TEX)
- Low-impact or natural dyes, disclosed dye process
- No added synthetic performance finishes on natural fiber
- Reinforced, repairable construction
- Disclosed factory location and labor practices
Red Flags
- Synthetic fiber as the primary material, especially against skin
- PFAS-based water/stain repellent treatments
- Undisclosed or "proprietary" fabric treatments
- Formaldehyde-based wrinkle-resistant finishing
- Fast-fashion construction signaling short intended lifespan
Evaluation Questions
- What is the fiber content, and is any of it certified organic?
- Is the fabric treated with anything beyond dye?
- Is the dye process disclosed, and is it low-impact or natural?
- Will the construction hold up to years of regular wear and washing?
- Is manufacturing origin and labor practice disclosed?
Tradeoffs
100% natural fiber vs. performance/stretch: A small percentage of elastane for fit (e.g., 3-5% in waistbands) is a reasonable, common compromise most people accept.
Organic vs. conventional cotton: Conventional cotton isn't automatically disqualifying — dye/finishing chemistry matters more than the raw fiber growing method.
Durability vs. price: A well-constructed garment at a higher price is usually the better long-run value; this is disclosed, not assumed.
Tier Definitions
Tier 1: Predominantly certified-organic or otherwise verified natural fiber, disclosed low-impact dye, no added synthetic performance finishes, durable construction, transparent manufacturing.
Tier 2: Natural-fiber-dominant with a minor synthetic component, or natural fiber without organic certification but no red-flag finishing chemistry.
Tier 3: Meets basic safety thresholds (no PFAS, no formaldehyde finishing) but may be majority synthetic blend or lack fiber/dye transparency.
Exceptions
- Technical/athletic gear with genuine performance synthetics may be evaluated on a separate, disclosed basis rather than penalized identically to everyday wear.
- Budget constraints and regional availability are acknowledged — Tier 3 exists for this.
Future Research Notes
- Monitoring PFAS regulation changes affecting "performance" fabric treatments.
- Emerging natural performance fibers (merino blends, lyocell) need a clearer green-flag threshold.
- Microplastic shedding from synthetic-blend garments during washing is an active research area.
The mouth absorbs ingredients directly through mucous membranes, and oral care is used daily for life. ROOTED's concern is both formulation (what's actually in it) and the physical product itself, since toothbrushes and floss are frequently single-use plastic.
Short, disclosed ingredient listsNatural abrasives and flavoring, not artificial sweeteners or dyesBiodegradable or compostable flossSodium lauryl sulfate (SLS) as a primary surfactantArtificial sweeteners or dyes with no functional purposeTriclosan or other persistent antibacterial agents
Read the full standard →
What We're Optimizing For
- Ingredient simplicity and disclosed formulation
- Avoidance of unnecessary synthetic additives
- Material honesty in hard-goods
- Reduced single-use plastic waste where a durable alternative performs equivalently
Green Flags
- Short, disclosed ingredient lists
- Natural abrasives and flavoring, not artificial sweeteners or dyes
- Biodegradable or compostable floss
- Replaceable-head or durable-handle toothbrush designs
- Independent lab testing disclosed
Red Flags
- Sodium lauryl sulfate (SLS) as a primary surfactant
- Artificial sweeteners or dyes with no functional purpose
- Triclosan or other persistent antibacterial agents
- PTFE-coated or fully synthetic floss with no alternative offered
- Fully disposable plastic toothbrush with no recycling/replacement program
Evaluation Questions
- Is the full ingredient list disclosed, and is it short relative to category norms?
- Does the formula contain SLS, artificial dyes/sweeteners, or triclosan?
- What is the product physically made from, and is any part single-use plastic with no better-designed alternative?
- Does the product contain fluoride? Fluoride products are not Rooted Approved and are capped at Tier 3.
- Is there independent testing behind any safety claim?
Tradeoffs
Fluoride vs. fluoride-free: Fluoride products are not Rooted Approved. They are capped at Tier 3 and cannot reach Tier 1 or Gold Standard, as a standards rule rather than a judgment made product by product. This is a position, and it is worth stating what it does and does not rest on: topical fluoride has genuine cavity-prevention evidence behind it, and ROOTED does not claim it is proven harmful at the doses used in toothpaste. The concern is cumulative exposure across every source at once, and particularly children, who swallow some of what they brush with. Hydroxyapatite is the alternative ROOTED points to. Reasonable people land on both sides of this, and anyone with a history of decay should take the question to their dentist.
Plastic-free vs. functional performance: A bamboo-handled brush with a nylon bristle head is a reasonable middle ground — full bristle "naturalness" isn't required.
Tier Definitions
Tier 1: Short, disclosed ingredient list free of SLS/artificial dyes/triclosan; durable or reduced-waste hard-goods design; fluoride-free formula. A fluoride active ingredient caps a product at Tier 3 regardless of the rest of the formula.
Tier 2: Minor formulation compromise or standard plastic hard-goods without a waste-reduction design, while avoiding all red-flag ingredients.
Tier 3: Avoids the most significant red flags but may contain SLS or be a fully conventional disposable design.
Exceptions
- Orthodontic and retainer products prescribed by a dental professional are evaluated for material safety only, not penalized for lack of "natural" branding.
- Travel-sized conventional products get the same standard as full-size.
Future Research Notes
- Microplastic exposure from toothbrush bristle wear — limited current data.
- Tracking independent (non-industry-funded) research on SLS irritation prevalence.
- Silicone-based interdental tools need a clearer green/red-flag position as more appear.
Cookware experiences repeated heating and direct food contact, which makes material choice unusually consequential — heat accelerates coating breakdown. Materials that don't need a coating to function (stainless, cast iron, carbon steel, glass) are structurally simpler to trust.
Fully inert base material: stainless steel, cast iron, carbon steel, borosilicate glass, uncoated ceramicNo PTFE, PFOA, or other PFAS coatingsFully disclosed base material and coating compositionPTFE/PFAS non-stick coatings, regardless of "PFOA-free" marketingUndisclosed "proprietary" non-stick coating compositionPlastic components in direct hot-food contact
Read the full standard →
What We're Optimizing For
- Food-contact material safety (inert vs. coated surfaces)
- Durability and realistic lifetime value
- Absence of unnecessary plastic in direct food contact
- Honest heat-safety limits
Green Flags
- Fully inert base material: stainless steel, cast iron, carbon steel, borosilicate glass, uncoated ceramic
- No PTFE, PFOA, or other PFAS coatings
- Fully disclosed base material and coating composition
- Wood, stainless, or silicone (not plastic) utensils for hot-food contact
- Designed for multi-decade use with available replacement parts
Red Flags
- PTFE/PFAS non-stick coatings, regardless of "PFOA-free" marketing
- Undisclosed "proprietary" non-stick coating composition
- Plastic components in direct hot-food contact
- Aluminum cookware with no anodized or sealed surface
- Documented coating breakdown at normal cooking temperatures
Evaluation Questions
- What is the base material, and does it require a coating to function?
- If coated, is the coating fully disclosed, and PFAS-free — not just "PFOA-free"?
- What plastic, if any, touches food during normal use, and at what temperature?
- Is the product designed and warrantied for long-term (10+ year) use?
- Are there documented, independent reports of coating degradation under normal use?
Tradeoffs
Non-stick convenience vs. inert material: ROOTED does not currently consider mainstream non-stick coatings (PTFE or ceramic-based) Tier 1 — this is a real, conscious convenience tradeoff people make.
Cast iron/carbon steel maintenance vs. stainless convenience: Not a safety tradeoff, just a usability one — noted, not scored.
Weight/heat retention vs. ease of handling: Disclosed, not penalized.
Tier Definitions
Tier 1: Fully inert base material with no coating required for function, no plastic in hot-food contact, disclosed manufacturing.
Tier 2: Inert base material with a minor plastic component not in food contact, or a fully disclosed ceramic-based non-stick coating with no PFAS.
Tier 3: Conventional non-stick with disclosed "PFOA-free" PTFE coating and no documented early degradation.
Exceptions
- Professional/commercial kitchen equipment evaluated separately where a consumer standard doesn't apply.
- Baby-feeding cookware/utensils held to a stricter version of this standard, not a looser one.
Future Research Notes
- Tracking PFAS regulatory action (several states have passed or proposed cookware-specific bans).
- "Ceramic non-stick" covers genuinely different chemistries — needs clearer sub-classification.
- Aluminum core (anodized, sandwiched) cookware needs more specific criteria.
Water is consumed constantly and in large volume, which makes even small per-serving differences meaningful over a lifetime. The standard spans two questions: what's filtered out of (or added to) the water, and what it sits in before reaching someone's mouth.
NSF/ANSI-certified filtration for the specific contaminants claimed (42, 53, 58, or 401)Stainless steel, glass, or genuinely BPA/BPS/phthalate-free containersRemineralization disclosed for methods that strip mineralsFiltration claims with no independent certification behind themPolycarbonate (#7) plastic bottles or undisclosed "BPA-free" plasticReverse osmosis/distillation with no remineralization option
Read the full standard →
What We're Optimizing For
- Verified contaminant reduction, not just marketing claims
- Container material safety under heat or repeated reuse
- Avoidance of unnecessary mineral stripping without remineralization
- Realistic filter lifespan and maintenance disclosure
Green Flags
- NSF/ANSI-certified filtration for the specific contaminants claimed (42, 53, 58, or 401)
- Stainless steel, glass, or genuinely BPA/BPS/phthalate-free containers
- Remineralization disclosed for methods that strip minerals
- Clear, published filter replacement schedule tied to real capacity testing
Red Flags
- Filtration claims with no independent certification behind them
- Polycarbonate (#7) plastic bottles or undisclosed "BPA-free" plastic
- Reverse osmosis/distillation with no remineralization option
- Filter lifespan claims not backed by capacity testing data
- Undisclosed bottled water sourcing
Evaluation Questions
- Is the filtration independently certified for the specific contaminants it claims?
- What is the container/system built from, and is it stable under realistic heat/reuse?
- If minerals are stripped, is remineralization addressed?
- Is the maintenance schedule realistic and disclosed, not just marketed?
- For bottled water, is source and treatment disclosed?
Tradeoffs
Filtration thoroughness vs. mineral content: Aggressive filtration removes more contaminants but also strips beneficial minerals — resolved by remineralization, not by picking a weaker filter.
Convenience of bottled vs. environmental/plastic tradeoff: Not disqualified for convenience use, but disclosed as secondary to home filtration where available.
Upfront system cost vs. long-term cost: A certified system usually costs less per gallon over time than routine bottled water.
Tier Definitions
Tier 1: Independently certified filtration for its specific claims, inert container material, remineralization addressed if applicable, realistic disclosed maintenance.
Tier 2: Certified filtration with a minor gap, or a generally safe plastic container without full third-party verification.
Tier 3: Basic, uncertified but reputable-brand filtration — meaningfully better than tap alone.
Exceptions
- Emergency preparedness water storage/purification evaluated against different, disclosed criteria (shelf stability, portability).
- Regional water quality varies significantly; a product may be rated with a note on which contaminant profile it's most relevant for.
Future Research Notes
- PFAS-specific filtration certification is fast-moving; needs regular review.
- Microplastic shedding from plastic filtration housings is an open research question.
- Structured/hexagonal water claims currently lack independent scientific support.
Personal care products are applied directly to skin, often daily, and many ingredients are absorbed rather than just sitting on the surface. This is also the category most saturated with "clean beauty" marketing that doesn't correspond to real formulation differences.

Read the full standard →
What We're Optimizing For
- Ingredient simplicity and full disclosure
- Avoidance of endocrine-disrupting or flagged synthetic ingredients
- Genuine efficacy — "natural" doesn't override "it needs to work"
- Packaging material safety for leave-on, high-contact products
Green Flags
- Full ingredient disclosure, including fragrance components
- Recognizable, minimally processed ingredients where formulation allows
- Relevant third-party certification (USDA Organic, EWG Verified, Leaping Bunny)
- Mineral-based UV filters, disclosed nanoparticle status
- Glass, aluminum, or verified-safe plastic packaging for leave-on products
Red Flags
- Undisclosed "fragrance"/"parfum" hiding an unlisted mixture
- Chemical UV filters with documented hormone-disruption concern, undisclosed
- Parabens, phthalates, or formaldehyde-releasing preservatives
- Undisclosed aluminum compounds in "natural"-marketed antiperspirants
- Talc without disclosed asbestos-testing verification
Evaluation Questions
- Is the full ingredient list disclosed, including what's inside "fragrance"?
- Does the formula contain any flagged ingredient (parabens, phthalates, oxybenzone, etc.)?
- Does it actually perform its stated function, based on independent evidence?
- For sun protection: is UV filter type and nanoparticle status disclosed?
- Is the packaging appropriate for a leave-on, repeated-use product?
Tradeoffs
"Clean" formulation vs. proven efficacy: ROOTED does not rate a poorly-performing natural product above a well-formulated conventional one purely on ingredient philosophy.
Mineral vs. chemical sunscreen: Mineral is the green-flag default, but texture/cosmetic-elegance tradeoffs are real — a product someone won't wear provides zero protection.
Antiperspirant function vs. ingredient simplicity: Blocking sweat requires an active ingredient; evaluated on its own safety merits.
Tier Definitions
Tier 1: Full ingredient transparency, no flagged ingredients, demonstrated efficacy, appropriate packaging.
Tier 2: Mostly clean formulation with one minor flagged ingredient at low concentration and clear disclosure, or proven-effective conventional formula with a documented, minor tradeoff.
Tier 3: Avoids the most significant red flags but may rely on undisclosed "fragrance" or lack third-party verification.
Exceptions
- Prescription or dermatologist-directed treatments evaluated for safety of inactive ingredients only — the active ingredient is a medical decision, outside ROOTED's scope.
- Costume/theatrical or occasional-use cosmetics may be held to a lighter standard than daily-wear products.
Future Research Notes
- Tracking FDA/EU regulatory divergence on flagged ingredients.
- Nanoparticle mineral sunscreen absorption research is still developing.
- "Fragrance-free" vs. "unscented" needs clearer, consistent evaluation language.
Local Food Map (CSA & Local Food Sourcing)
Buying directly from a farm shortens the distance between grower and eater. This category functions as a directory rather than a tiered rating — the aim is that every listing is real, current, and genuinely direct-from-source, since the core value comes from the sourcing model itself. Each listing's map pin is checked against its published address; that confirms the pin matches the address, not that the address is right.
Certified Organic, Certified Naturally Grown, or California Certified Farmers' Market statusNamed, identifiable farms behind the produceEstablished operating history or an active, verifiable current presenceNo verifiable current operating statusVague or unverifiable sourcing claims with no named farm or regionFood banks or hunger-relief operations mischaracterized as consumer CSAs
Read the full standard →
What We're Optimizing For
- Verified, current operating status
- Genuine direct-from-farm or farmer-supplied sourcing, not a relabeled distributor
- Clarity on what "organic," "certified," or "grass-fed" claims actually mean per listing
- Real, checkable logistics
Green Flags
- Certified Organic, Certified Naturally Grown, or California Certified Farmers' Market status
- Named, identifiable farms behind the produce
- Established operating history or an active, verifiable current presence
- Sliding-scale or accessible pricing options
- Specific, checkable pickup/delivery logistics
Red Flags
- No verifiable current operating status
- Vague or unverifiable sourcing claims with no named farm or region
- Food banks or hunger-relief operations mischaracterized as consumer CSAs
- Pay-to-play placement of any kind
Evaluation Questions
- Is this currently operating, confirmed via the organization's own current website — not just an old article?
- Is the produce traceable to specific named farms, or an anonymous aggregator?
- Are pickup/delivery logistics specific and checkable?
- Are organic/certification claims actually backed by the certifying body, or just asserted?
- Does the listing serve the geographic area it claims to?
Tradeoffs
Certified organic vs. "practicing organic" small farms: Certification cost is a real barrier for small operations, not a signal of lower quality — disclosed per listing, not excluded.
Established/large market vs. small/informal CSA: Both listed when verifiable; a large certified market isn't inherently more trustworthy than a small farm-direct CSA.
Tier Definitions
Tier 1: Not applicable in the Tier 1/2/3 sense. Listings are not ranked against one another, and none pays for its place on the map.
Exceptions
- Markets/CSAs disrupted by disaster are listed with a clear "returning" status and date rather than removed, if return is confirmed via reliable current reporting.
- Seasonal-only operations are listed with their actual season noted.
Future Research Notes
- Building a recurring re-verification cadence so listings don't silently go stale as the map grows.
- Expanding beyond the current LA/Santa Monica curated layer into other cities.
- Considering a "last verified" date shown per listing.
Food is consumed more frequently and in greater volume than any other category, so small quality differences compound significantly over time. The focus is nutrient density, ingredient integrity, and sourcing transparency — not a specific diet ideology.
Short ingredient lists of recognizable, whole-food ingredientsVerified organic, regenerative, or pasture-raised sourcing with named farms/regionsMinimal processing relative to category normLong ingredient lists dominated by industrial additives, gums, and stabilizers with no functional necessitySeed oils as a primary fat source when a more stable alternative exists in-categoryAdded sugars under multiple disguised names
Read the full standard →
What We're Optimizing For
- Nutrient density relative to processing level
- Ingredient list simplicity and recognizability
- Sourcing transparency
- Absence of unnecessary industrial additives
Green Flags
- Short ingredient lists of recognizable, whole-food ingredients
- Verified organic, regenerative, or pasture-raised sourcing with named farms/regions
- Minimal processing relative to category norm
- Third-party certification (USDA Organic, Certified Humane, Regenerative Organic Certified)
Red Flags
- Long ingredient lists dominated by industrial additives, gums, and stabilizers with no functional necessity
- Seed oils as a primary fat source when a more stable alternative exists in-category
- Added sugars under multiple disguised names
- Artificial colors, flavors, and preservatives with documented health concern flags
- Opaque sourcing ("natural flavors," no origin disclosed)
Evaluation Questions
- How long is the ingredient list, and how many ingredients are recognizable whole foods?
- What is the primary fat source, and is it stable and minimally processed?
- Is sourcing (farm, region, or country of origin) disclosed?
- Are added sugars disclosed clearly, not split across multiple names?
- Is there third-party certification behind any sourcing claim?
Tradeoffs
Convenience/packaged food vs. whole-food ideal: Packaged food is evaluated on its own curve relative to other packaged options, not penalized for not being unprocessed.
Organic vs. local: When these conflict, both documented as valid, different priorities rather than one being universally superior.
Cost vs. quality: Genuinely acknowledged as real; Tier 3 exists specifically for this.
Tier Definitions
Tier 1: Short, whole-food ingredient list, disclosed and verified sourcing, no red-flag additives, minimal processing for its category.
Tier 2: Mostly clean formulation with one or two minor compromises and no major red flags.
Tier 3: Avoids the most significant red flags but may have less sourcing transparency or a longer ingredient list.
Exceptions
- Medically necessary or allergen-driven formulations evaluated with that constraint disclosed.
- Emergency/shelf-stable food preparedness held to a different standard than daily-consumption food.
Future Research Notes
- Needs a clear internal position on contested topics (seed oils, saturated fat) — acknowledging genuine scientific debate rather than presenting one side as settled.
- Regenerative agriculture certification is still maturing; needs periodic review.
People spend roughly a third of their life in direct, prolonged skin contact with bedroom textiles, often in a warm, humid microclimate that can increase chemical transfer. Mattresses are dense, hard-to-replace items where a material choice made once affects years of nightly exposure.

Read the full standard →
What We're Optimizing For
- Natural fiber content in direct-contact textiles
- Absence of flame-retardant and off-gassing chemical treatments
- Certified material sourcing
- Realistic durability and lifespan
Green Flags
- GOTS-certified organic cotton, linen, or verified-process bamboo-derived sheets
- GOLS-certified organic latex, or untreated natural wool/cotton fill
- CertiPUR-US or GREENGUARD Gold certification where foam is used
- Wool as a natural, non-chemical flame-retardant layer
Red Flags
- Undisclosed flame-retardant chemistry
- Polyester-dominant sheets marketed with vague "cooling" language and no fiber disclosure
- Memory foam with no CertiPUR-US or equivalent certification
- Undisclosed synthetic fill in "natural"-marketed pillows
Evaluation Questions
- What is the fiber content of direct-contact textiles, and is it certified?
- If foam or latex is used, is it certified for low emissions?
- How is flame resistance achieved — chemical treatment or natural material property?
- Is fill material (down, wool, synthetic) disclosed accurately?
- What is the realistic expected lifespan before material breakdown?
Tradeoffs
Natural latex firmness/cost vs. memory foam contouring: A genuine preference and performance tradeoff — both can reach Tier 1/2 depending on certification.
Wool flame-barrier vs. synthetic-free claims: Some "natural" mattresses use wool specifically as flame protection — this is the green-flag approach, not a compromise.
Tier Definitions
Tier 1: Certified organic/natural fiber content, certified low-emission foam/latex if used, natural flame-resistance approach, full material disclosure.
Tier 2: Natural-fiber-dominant with a minor synthetic or uncertified component, or certified foam without full organic fiber certification elsewhere.
Tier 3: Avoids undisclosed chemical flame retardants and has basic certification but may be predominantly synthetic fiber.
Exceptions
- Medical/adjustable bed bases and specialty support surfaces evaluated on functional and safety merit separately.
- Children's bedding held to a stricter, not looser, version of this standard.
Future Research Notes
- Flame-retardant regulation varies by state; needs periodic review.
- Bamboo fiber processing methods vary widely (mechanical vs. chemical/viscose) with very different safety profiles.
Cleaning products are used in enclosed indoor spaces and residue frequently contacts food-prep surfaces, skin, or gets inhaled during use. The concern is both immediate (exposure during use) and residual (what's left on a surface a plate later sits on).
Full ingredient disclosure, including surfactant and fragrance componentsEPA Safer Choice or equivalent independent certificationBiodegradable, phosphate-free formulationsUndisclosed "fragrance" in a product used in enclosed spacesChlorine bleach and ammonia-adjacent products marketed for the same use caseUndisclosed quaternary ammonium compounds ("quats") with respiratory irritant concern
Read the full standard →
What We're Optimizing For
- Ingredient disclosure and avoidance of respiratory irritants
- Indoor air quality impact during and after use
- Biodegradability and environmental impact after disposal
- Genuine cleaning efficacy, not sacrificed for "natural" branding
Green Flags
- Full ingredient disclosure, including surfactant and fragrance components
- EPA Safer Choice or equivalent independent certification
- Biodegradable, phosphate-free formulations
- Concentrated/refillable formats reducing plastic packaging waste
Red Flags
- Undisclosed "fragrance" in a product used in enclosed spaces
- Chlorine bleach and ammonia-adjacent products marketed for the same use case
- Undisclosed quaternary ammonium compounds ("quats") with respiratory irritant concern
- Glycol ethers in spray-format cleaners with no ventilation warning
- Antibacterial claims using agents of environmental concern with no demonstrated added benefit
Evaluation Questions
- Is the full ingredient list disclosed, including fragrance components?
- What is the primary active cleaning agent, and its irritation profile?
- Is the product independently certified?
- Does it actually clean effectively, based on independent testing?
- Is it biodegradable and phosphate-free?
Tradeoffs
"Natural" cleaning vs. disinfecting efficacy: Plant-based cleaners are often excellent at general cleaning but genuinely weaker at disinfecting — disclosed rather than overclaimed.
Fragrance-free vs. consumer preference for scent: Fragrance-free is the default, but disclosed-ingredient scented options aren't automatically disqualified.
Tier Definitions
Tier 1: Full ingredient disclosure, independently certified, biodegradable, no red-flag irritants, demonstrated efficacy.
Tier 2: Mostly disclosed formulation with one minor undisclosed, low-concern component and no major red flags.
Tier 3: Avoids the most serious hazards but may lack full transparency or third-party certification.
Exceptions
- Products needed for disinfection during illness or in medical/eldercare settings evaluated with efficacy weighted more heavily.
- Industrial/commercial-strength products are out of scope for this consumer standard.
Future Research Notes
- Indoor air quality research on VOC off-gassing is active and evolving.
- EPA Safer Choice certification coverage is not universal across all subcategories yet.
Lighting & Circadian Health
Light is a genuine biological timing signal, not just illumination. The concern isn't any single bulb — it's whether the light in a room matches what the body expects at that time of day: bright and blue-shifted in the morning, dim and warm in the evening.
Genuinely warm color temperature (2700K or lower) available for evening useDisclosed CRI, flicker data, and lumens rather than vague marketing claimsVerified low-blue spectral output for red/amber evening products, not just a color name"Blue light glasses" with no published spectral transmission dataBright white or blue LED night lights and alarm clock displaysUndisclosed PWM flicker frequency in dimmable LED products
Read the full standard →
What We're Optimizing For
- Matching light timing and color temperature to the body's actual circadian expectations
- Verified spectral data over marketing color names, especially for red/amber "circadian" products
- Minimizing light pollution in sleep spaces from displays, night lights, and indoor fixtures
- Not treating every LED as automatically inferior to incandescent when it's genuinely well-specified
Green Flags
- Genuinely warm color temperature (2700K or lower) available for evening use
- Disclosed CRI, flicker data, and lumens rather than vague marketing claims
- Verified low-blue spectral output for red/amber evening products, not just a color name
- Natural materials (wood, ceramic, linen, glass) in fixtures and shades over all-plastic construction
Red Flags
- "Blue light glasses" with no published spectral transmission data
- Bright white or blue LED night lights and alarm clock displays
- Undisclosed PWM flicker frequency in dimmable LED products
- Red-tinted covers over full-spectrum white bulbs marketed as circadian-friendly
- "Digital eye strain" or all-day blue-light-blocking claims with no supporting evidence disclosed
Evaluation Questions
- Is the color temperature and CRI actually disclosed, or only a vague marketing name?
- For red/amber products, is there published spectral data confirming genuinely low blue content?
- Does the product introduce light pollution into a space meant to stay dark (bedroom, nursery)?
- Is a health or circadian claim backed by disclosed evidence, or just a color and a claim?
Tradeoffs
Incandescent/halogen vs. well-specified LED: True incandescent has zero driver electronics to flicker, but a genuinely high-CRI, flicker-free, warm-dimmable LED is a legitimate modern option — not an automatic downgrade.
Evening blue-light glasses vs. simply dimming lights: Dimming and warming ambient light in the evening addresses the same mechanism as blue-blocking glasses, for free, without wearing anything — glasses are a genuine option, not the only one.
Tier Definitions
Tier 1: Fully disclosed spectral/CRI/flicker data, genuinely matches its stated circadian use case, natural materials where applicable.
Tier 2: Mostly disclosed specs with one minor gap, or good performance without full independent verification.
Tier 3: Avoids the worst red flags but lacks meaningful disclosure or verification.
Exceptions
- Commercial and industrial lighting applications are out of scope for this consumer standard.
- Medical photobiomodulation (red light therapy) devices are evaluated separately from ambient circadian lighting — different purpose, different standard.
Future Research Notes
- Research on low-level, non-visible PWM flicker's effects on sensitive individuals is still developing.
- Melanopic lux as a standardized measurement is gaining adoption but isn't yet universal across product listings.
Indoor air is where most people spend the majority of their time, and most problems in it are invisible without measurement. The focus is separating genuinely effective, independently tested equipment — purifiers, humidity control, monitors, and ventilation — from marketing-driven claims that don't correspond to measurable performance.

Read the full standard →
What We're Optimizing For
- Verified filtration performance (CADR, true HEPA vs. "HEPA-type")
- Absence of ozone-generating technology in purifiers
- Humidity control equipment sized correctly and built to resist mold/bacterial growth rather than harbor it
- Monitors and detectors independently validated for accuracy, not just brand-reported
- Realistic, disclosed filter/consumable replacement cost and schedule
Green Flags
- True HEPA filtration with a disclosed, independently verified CADR rating
- No ionization or ozone-generation technology, or independently verified to produce no measurable ozone
- Transparent, reasonably priced replacement filter or consumable availability
- Humidifiers with easily cleanable tanks and antimicrobial-relevant design (not just a marketing claim) to limit mold/bacterial growth
- Dehumidifiers with an Energy Star rating and disclosed, independently-relevant pint-per-day capacity for their marketed room size
- Monitors and radon detectors independently validated against reference instruments or certified testing protocols (e.g., AARST-NRPP for radon)
Red Flags
- "Ionic" or "ozone" purifiers with no independent ozone-output testing
- "HEPA-type"/"HEPA-like" language (not true HEPA)
- No disclosed CADR rating or unsupported square-footage claims
- Proprietary, expensive, hard-to-source filters relative to unit price
- Humidifiers with no meaningful way to clean the tank, inviting mold/bacterial growth
- Air quality monitors or radon detectors with no independent accuracy validation, only brand-reported specs
Evaluation Questions
- Is the filtration true HEPA, and is CADR independently verified?
- Does the unit generate ozone or ions, and is output independently tested?
- Is the unit appropriately sized for its marketed use case?
- Are replacement filters or consumables reasonably available and priced?
- For humidifiers, is the tank easy to clean and does the design limit stagnant water?
- For monitors and radon detectors, has accuracy been independently validated, or only asserted by the brand?
- Is there independent, non-brand-published performance data?
Tradeoffs
Noise vs. filtration power: Higher CADR often means more fan noise — disclosed per product, not folded into the safety score.
Whole-home ventilation vs. portable purifiers: Different investment levels and different problems solved — evaluated on their own merits.
Continuous vs. short-term radon testing: A continuous monitor gives an ongoing picture and catches seasonal variation; a short-term test kit is cheaper and simpler but only a snapshot.
Tier Definitions
Tier 1: True HEPA with independently verified CADR (or equivalent independent validation for monitors/detectors), no ozone generation, appropriately sized, accessible replacement filters/consumables.
Tier 2: True HEPA with brand-reported CADR, or a strong unit with a moderately priced/available filter ecosystem, or a monitor with reasonable but not fully independently verified accuracy.
Tier 3: Decent performance without full independent verification, and no ozone-generation or unvalidated-accuracy red flag.
Exceptions
- Medical-grade air filtration for specific respiratory conditions evaluated against clinical standards.
- Industrial/commercial HVAC filtration is out of scope.
- Radon mitigation system installation (as opposed to detection) is a licensed-contractor service, out of scope for a product rating.
Future Research Notes
- Needs a clear, written position on ionization technology generally.
- Smart/connected purifiers and monitors with sensor-based operation may need their own evaluation criteria as the market matures.
- Consumer-grade radon monitor accuracy compared to professional AARST-NRPP-certified testing needs periodic re-review.
Covers recovery equipment with a wide range of evidence quality behind it — sauna use has substantial research, cold exposure a growing but mixed one, and grounding limited rigorous evidence relative to its marketing. Equipment build quality and safety are evaluated independent of how strong the underlying wellness claim is.

What We're Optimizing For
- Material safety at temperature extremes
- Electrical/mechanical safety for heated or refrigerated equipment
- Honest framing of wellness claims relative to actual evidence strength
- Realistic durability for wet/extreme-temperature conditions
Green Flags
- Solid wood sauna construction free of VOC-emitting sealants/adhesives at heat-exposed surfaces
- Independent electrical safety certification (UL, ETL) for heaters and chillers
- Disclosed material safety data for cold plunge tub materials
- Wellness claims clearly labeled "may help" rather than guaranteed, where evidence is preliminary
Red Flags
- Composite wood/particleboard sauna construction with adhesive off-gassing risk under heat
- No independent electrical safety certification on heating/chilling elements
- Grounding products making disease-treatment claims without clinical evidence
- Plastic cold plunge tubs with no disclosed material safety data
Evaluation Questions
- What is the sauna's construction material, and is it free of high-heat off-gassing risk?
- Is the heating or chilling element independently safety-certified?
- Are wellness claims proportionate to actual evidence?
- What material is a cold plunge tub made from, and is it rated for sustained cold/wet use?
- Is the equipment realistically durable for its intended frequency of use?
Tradeoffs
Traditional (wood-fired) vs. electric sauna: Different heat profiles and practical tradeoffs — evaluated on build quality and safety within each type.
DIY cold plunge vs. purpose-built unit: A well-built DIY setup with a safety-certified chiller can reasonably reach the same tier as a purpose-built product.
Tier Definitions
Tier 1: Safe, low-off-gassing materials at heat-exposed surfaces, independently certified electrical components, claims proportionate to evidence.
Tier 2: Solid construction with a minor certification gap from an established, reputable manufacturer, and reasonable claims.
Tier 3: Functional, reasonably safe equipment without full independent certification.
Exceptions
- Home-built saunas from raw, disclosed lumber and a certified heater are evaluated as a system, not excluded for being non-commercial.
Future Research Notes
- Grounding/earthing evidence quality should be reassessed periodically.
- Contrast therapy protocols are an active research area; standard may eventually need protocol-level guidance.
Supplements are the least regulated category ROOTED covers — they don't require FDA approval before sale, which places an unusually high burden on independent verification. The standard leans harder on third-party testing than almost any other category.

Read the full standard →
What We're Optimizing For
- Third-party lab verification of label-claim accuracy
- Bioavailable, well-studied forms of active ingredients
- Absence of unnecessary fillers and proprietary-blend obfuscation
- Contaminant testing, especially for botanicals and fish-derived products
Green Flags
- NSF Certified for Sport, USP Verified, or ConsumerLab-tested products
- Fully disclosed dosing per ingredient, no "proprietary blend"
- Well-studied, bioavailable ingredient forms
- Third-party heavy-metal and contaminant testing disclosed
Red Flags
- "Proprietary blend" labeling hiding individual ingredient doses
- No third-party testing of any kind
- Poorly absorbed, cheap ingredient forms substituted with no disclosure
- Unsubstantiated disease-treatment claims
- Undisclosed fillers or unnecessary additives
Evaluation Questions
- Is the product third-party tested for label-claim accuracy, and is that testing publicly available?
- Are all ingredient doses individually disclosed?
- What form is each active ingredient in, and is it well-studied and bioavailable?
- Is there contaminant testing disclosed?
- Are claims proportionate to actual clinical evidence?
Tradeoffs
Cost of third-party-tested products vs. budget options: Independent testing meaningfully raises cost — Tier 3 exists for reputable-but-untested products rather than excluding budget options entirely.
Single-ingredient vs. formulated blends: Blends aren't disqualified but require full dose disclosure to reach Tier 1.
Tier Definitions
Tier 1: Third-party tested for label accuracy and contaminants, fully disclosed dosing, well-studied bioavailable ingredient forms.
Tier 2: Third-party tested for label accuracy but not full contaminant panel, or fully disclosed dosing from an established, reputable manufacturer without independent verification.
Tier 3: No independent testing, but full dosing disclosure and no red-flag ingredient forms.
Exceptions
- Practitioner-dispensed or prescription-adjacent supplements evaluated with that context noted, not held to a stricter consumer-retail standard.
Future Research Notes
- FDA regulatory changes to supplement oversight should be tracked closely.
- Emerging ingredient categories (novel adaptogens, mushroom extracts) need a clear way to flag "promising but early evidence" versus well-established ingredients.
