Pixie Menstrual Cups
Lower-concern product; silicone menstrual cups are not a typical PFAS application, but brand makes no explicit PFAS disclosure.
Pixie Cup makes medical-grade silicone menstrual cups, a material category with lower inherent PFAS risk compared to nonstick, waterproof, or stain-resistant products. The brand does not publicly disclose PFAS testing or claim PFAS-free status.

The full breakdown
What it's made of and why it matters
Pixie Cups are manufactured from medical-grade silicone, the same material class used in FDA-cleared medical devices like implants and catheters. This silicone is chemically inert at body temperature and does not leach into menstrual fluid under normal use. Unlike latex or plastic alternatives, silicone has no known endocrine disruptors or plasticizers added during manufacture. The material is non-porous, antimicrobial by design, and does not degrade from repeated sterilization.
The brand's record and disclosure
Pixie Cup makes no explicit public statement on PFAS testing or avoidance, which is typical for menstrual cup manufacturers but represents a disclosure gap. The company has no recorded recalls, safety warnings, or litigation related to product contamination. Third-party certifications (FDA compliance, materials testing) are not prominently documented on their website based on available public information. No independent safety controversies have been reported.
How it compares in its category
Menstrual cups occupy a unique safety niche: they are reusable, worn internally, and made from a much narrower material palette than other consumer products. Medical-grade silicone cups (Pixie, Diva, Saalt) are chemically more stable than disposable alternatives (applicators, pads with plastic films). Pixie's positioning is mid-market in the cup category without claims of special material sourcing or testing transparency that some premium competitors offer. All silicone cups carry similar internal-use risk profiles.
If you buy it
Sterilize between cycles by boiling for 5-10 minutes or using a dedicated cup sterilizer; do not use bleach or harsh solvents that can degrade the silicone seal over time. Replace the cup every 5 years or sooner if you notice discoloration, odor that does not wash away, or visible material tears. Do not expose to direct flame or extremely hot water above 85 degrees Celsius. Store in a breathable pouch in a cool, dry location to prevent mildew and odor absorption.
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.”
Bacterial or mold contamination from storage/care
If not sterilized properly between uses or stored in a sealed non-breathable container, menstrual cups can develop bacterial biofilm or mold. This risk is not specific to Pixie but is higher if users do not follow cleaning protocols.
Allergen response to silicone or additives
Medical-grade silicone is hypoallergenic for the vast majority of users. No documented cases of allergic reaction to Pixie Cup silicone have been reported; risk is theoretical and extremely rare.
Material degradation from heat or chemical exposure
Boiling or high-temperature sterilization is required and safe, but exposure to petrochemical solvents, oil-based lubricants, or extreme heat (open flame) can cause the silicone to harden or crack over years of use.
Toxic shock syndrome (TSS) from prolonged insertion
TSS is a general risk for any internal menstrual product, including cups. The risk is minimized by emptying and rinsing every 8-12 hours and sterilizing between cycles. Pixie Cup instructions include these guidelines; no Pixie-specific TSS cases are documented.
Unknown material composition or sourcing
Pixie Cup does not publicly disclose the supplier, manufacturing location, or third-party certification of its silicone. This limits ability to verify purity or absence of contaminants beyond brand assurance.
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.
