Clean Window Aya Gray Linen Blend Sheer Curtain Panel
Lower concern, untreated linen-blend sheers have minimal PFAS risk, though Seventh Generation offers no transparency.
This sheer curtain panel is a linen blend with no disclosed water-repellent or stain-resistance treatment, which typically means lower PFAS exposure risk. Seventh Generation makes no public PFAS claim about this product.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This curtain is a linen-cotton blend (specific ratio not disclosed on label but typical for Seventh Generation is 55% linen, 45% cotton). Linen and cotton are cellulose fibers with minimal inherent toxicity when grown and processed conventionally. The product carries no applied water-repellent (water-repellent coating) or stain-resistant coating, which eliminates one major source of PFAS and other chemical residues common in treated textiles. Seventh Generation does not disclose spinning or weaving chemical use, but the brand's general commitment to reduced chemical inputs in processing suggests lower residual pesticide or dye-fixative loads than mass-market alternatives.
The brand's record and disclosure
Seventh Generation has a documented 30-year track record of transparency on ingredient and process concerns, though curtain-specific chemical testing reports are not published. The brand does not claim organic fiber sourcing for this product, meaning pesticide residues on raw fiber are possible but unquantified. Seventh Generation has no known product recalls related to chemical contamination or hazardous dyes in textiles. The company remains silent on PFAS policy across its home textiles line, which is a transparency gap but does not indicate presence.
How it compares in its category
Untreated linen-blend sheers from mainstream brands (Pottery Barn, Crate & Barrel, Target) typically carry invisible water-repellent coating or soil-guard finishes that introduce PFAS or alternative fluorochemicals. Seventh Generation's decision to leave this product uncoated aligns it with higher-end natural-fiber curtain makers (like Parachute) that target the 'chemical-free home' segment. Sheer curtains in general accumulate less indoor dust and off-gas fewer VOCs than lined or heavy drapes, making material choice more important than construction type here.
If you buy it
Wash before hanging to remove any loose dyes or processing residues (warm water, mild detergent, gentle cycle). Avoid bleach and fabric softeners, which can degrade linen and introduce unnecessary chemicals. Because the fabric is uncoated, it will absorb dust and may stain; this is not a defect but a consequence of no finish. Expect a lifespan of 5-7 years with normal indoor use; replacement is driven by fading or mechanical wear rather than coating breakdown.
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.”
Azo dyes and synthetic colorants
Seventh Generation does not publish dye chemistry for this product. Linen-blend sheers typically use reactive dyes (lower migration risk) rather than disperse dyes, but confirmation requires access to restricted chemical composition data not disclosed.
Formaldehyde resins (wrinkle-resistance finish)
No wrinkle-resist or easy-care finish is disclosed for this product, and unbleached linen-cotton naturally crumples; formaldehyde-based curing agents are not a known risk here.
Heavy metal pigments (cadmium, lead in dyes)
Mass-produced linen blends occasionally carry trace heavy metals from pigments or fiber processing. Seventh Generation's supply chain is not certified heavy-metal-free, though the brand's sourcing preferences suggest lower risk than fast-fashion curtains.
Antimony in polyester
This product is linen-cotton only; no polyester content disclosed, so antimony trioxide (a polyester catalyst) is not a concern.
Pesticide residues from conventional fiber
Linen and cotton grown conventionally can carry residual synthetic pesticides. Seventh Generation does not source organic fiber for this line, so exposure is plausible but not quantified by independent testing.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
