303 Fabric Guard
Fabric guard with undisclosed treatment chemistry; high PFAS risk.
303 Fabric Guard is a spray-on protective coating for textiles with no public PFAS disclosure. Stain and water resistance treatments commonly contain PFAS; brand silence on chemistry raises concern.

Why this grade
Waterproof / stain-resistant treatment

other is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
303 Fabric Guard is a proprietary fabric coating marketed as water and stain repellent. The active chemistry is not disclosed publicly, which is standard practice for many commercial protectants but raises concern given widespread industry reliance on PFAS-based repellents. Without transparency on whether this product contains legacy PFAS (PFOA, PFOS) or replacement PFAS variants (GenX, ADONA), the true chemical profile remains unknown to consumers.
The brand's record and disclosure
Flectalon (the 303 brand parent) has not published clear public statements on PFAS use, phase-out timelines, or use of safer alternatives. No third-party certifications (GOTS, Bluesign, OEKO-TEX) are listed for this product. The silence itself is informative: brands actively phasing out PFAS typically advertise it; absence of such claims suggests either ongoing PFAS use or reluctance to commit to alternatives.
How it compares in its category
Fabric protectants span a spectrum: older products almost universally contained PFOA or PFOS; modern alternatives include fluorine-free hydrophobic polymers (polyurethane, silicone-based, or wax blends) or plant-derived options. 303 Fabric Guard sits in the middle of the market with no disclosed safer-chemistry claim, making it harder to distinguish from legacy PFAS formulations than from actively marketed PFAS-free competitors.
If you buy it
Apply only in well-ventilated spaces; avoid inhalation during spraying. Test on a hidden area first to confirm no discoloration or stiffening. Reapplication frequency depends on use; most fabric protectants last 6-12 months under normal wear. Do not apply to items that will be worn near the face or by infants; prioritize furniture and outerwear instead. If you are concerned about PFAS exposure, request a Safety Data Sheet (SDS) from the retailer and specifically ask the manufacturer whether PFAS is present.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
PFAS (fluorinated repellent chemistry)
Product lacks disclosure; fabric protectants of this type historically relied on PFAS. No public commitment to PFAS-free formulation is documented, making PFAS presence probable but not confirmed.
Inhalation risk from spray application
Aerosol/spray formulations carry risk of respiratory exposure to propellants and dispersed actives. Risk is manageable with outdoor or well-ventilated application but not negligible for enclosed spaces.
Skin sensitization or irritation
Proprietary repellent chemistry may include irritant or allergenic components; no full ingredient list is publicly available. Risk is low during normal use but higher during application if contact occurs.
Bioaccumulation via treated textiles
If formulation contains PFAS, treated fabrics shed fluorinated compounds through wear and laundering, contributing to environmental and dietary PFAS exposure over months to years.
Lack of safety transparency
No SDS, ingredient disclosure, or third-party testing is readily available to consumers. This non-disclosure pattern is consistent with products that may contain legacy PFAS or proprietary PFAS variants regulators have not yet restricted.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
