No. 918 Brandon Magnetic Closure Room Darkening Grommet 2-Piece Curtain Panel Pair
Lower concern; standard room-darkening curtains rarely treated with PFAS, but brand offers no transparency.
This is a basic polyester room-darkening curtain with magnetic closures. Seventh Generation does not disclose PFAS treatment, but room-darkening textiles typically use carbon-based or mineral pigments rather than Teflon-family coating coatings. The magnetic hardware poses minimal PFAS risk. No third-party verification available.

The full breakdown
What it's made of and why it matters
No. 918 Brandon curtains are polyester fabric with metal magnetic closure hardware. Polyester itself is a synthetic polymer stable at room temperature and not prone to leaching under normal use as a wall hanging. The darkening layer in polyester curtains is typically achieved through dense weave or pigment addition rather than chemical coatings, making degradation and particle release unlikely during typical hanging and gentle washing.
The brand's record and disclosure
Seventh Generation markets itself on eco-conscious household products and publishes ingredient disclosure for cleaners and personal care items, but does not publish material composition or chemical treatment data for home textiles on their website or product labels. No recalls or safety controversies specific to this curtain line are on record. The brand's silence on PFAS treatment in curtains reflects industry-wide lack of transparency rather than a known gap in their practices.
How it compares in its category
Room-darkening polyester curtains are a mainstream, lower-risk textile category because they are not worn against skin and not heated to high temperatures. Compared to flame-retardant heavy drapes or thermal-backed curtains, standard polyester room-darkeners avoid exposure to legacy brominated flame retardants. Seventh Generation's offering aligns with market standard for this segment and does not stand out as exceptionally hazardous or protective.
If you buy it
Machine wash in cool water with mild detergent to preserve fabric integrity and avoid unnecessary shedding. Avoid prolonged direct sunlight on the fabric side to slow photo-degradation and color fading, which can increase particulate release over years. Replace curtains if seams separate, fabric tears, or magnetic closures detach and are ingested by children or pets. No special ventilation or off-gassing time is needed; hang and use immediately.
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.”
Microplastic shedding from polyester
Polyester textiles shed fibers when washed, worn, or degraded over time. Room-darkening curtains in active use (opening, closing, handling) may release microfibers into indoor air and dust, though quantities from wall-hanging fabric are lower than from clothing or upholstered furniture.
Formaldehyde in fabric finishing resins
Seventh Generation does not disclose use of formaldehyde-releasing finishing resins on this product. Reputable manufacturers often avoid high-formaldehyde finishes in home textiles sold in North America, but no third-party testing of this specific product is publicly available.
Azo dyes and heavy metal pigments
The darkening color in these curtains relies on pigmentation, which may include azo dyes or heavy metal oxide pigments depending on supplier sourcing. Seventh Generation does not publish dye or pigment specifications, leaving unknown the risk of heavy metal or carcinogenic azo component presence.
Antimony in polyester fiber
Polyester fibers are sometimes produced using antimony as a catalyst during polymerization. Antimony typically remains bound in the polymer matrix and does not leach under room-temperature use, but no leaching data specific to this product exists.
Metal hardware corrosion and leaching
Magnetic closure hardware composition is not disclosed. If ferrous or zinc-plated, corrosion over years in humid environments could theoretically release metal particles into dust, but this is a low-priority concern for wall-mounted, non-contact hardware.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
