Lunette Menstrual Cup - Clear
Lower concern, medical-grade silicone menstrual cups are not a known PFAS vector, but Lunette does not publicly disclose PFAS testing.
Lunette Menstrual Cup is made from medical-grade silicone, a material not typically treated with PFAS or engineered to require water/stain resistance coatings. No published PFAS claims or third-party verification exist, but the product category and material composition pose minimal inherent risk.

The full breakdown
What it's made of and why it matters
Lunette cups are manufactured from medical-grade silicone (often specified as platinum-cure silicone), which is non-porous and chemically inert at body temperature and normal pH ranges. Medical-grade silicone does not contain BPA, phthalates, or other endocrine disruptors associated with lower-grade plastics. The material is designed to resist degradation from repeated sterilization (boiling, autoclaving) and vaginal flora exposure, making it stable over the product's 10-year lifespan if properly maintained.
The brand's record and disclosure
Lunette has operated since 2005 with no recorded product recalls or safety violations related to material contamination. The brand voluntarily certifies products to ISO 10993 (biocompatibility for medical devices) and FDA Class II medical device standards, demonstrating third-party testing for cytotoxicity, sensitization, and irritation. Lunette does not publicly disclose PFAS testing data, which is not atypical for menstrual cup manufacturers, though this represents a transparency gap rather than a confirmed risk.
How it compares in its category
Menstrual cups as a product category avoid nearly all hazards associated with disposable alternatives (bleach residues, synthetic fragrances, chlorine dioxins in tampons/pads). Lunette's medical-grade silicone specification is comparable to leading competitors (DivaCup, Saalt) and exceeds budget alternatives that use unspecified silicone grades. The main differentiator among established brands is certifications and reusability durability rather than chemical safety.
If you buy it
Sterilize by boiling for 20 minutes before first use and monthly thereafter; do not use bleach or harsh chemicals. Inspect the cup quarterly for visible wear, cracks, or cloudiness, which may indicate silicone degradation. Replace if you notice persistent odor despite cleaning, material discoloration, or changes in flexibility. Store in the provided pouch in a cool, dry location to minimize UV exposure and material aging.
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.”
Silicone material integrity degradation
Over extended use and repeated boiling cycles, medical-grade silicone can lose elasticity or develop microscopic fissures. Lunette specifies a 10-year lifespan; users should replace if material becomes brittle, discolored, or sticky.
Contamination from inadequate sterilization
If not boiled or cleaned properly between uses, bacterial biofilm can accumulate inside the cup, leading to odor, infections, or irritation. This is a user-maintenance issue rather than a material defect.
Allergic sensitization to silicone or additives
Rare cases of vulvovaginal irritation have been anecdotally linked to silicone cups in individuals with silicone sensitivity, though true IgE-mediated allergy to medical-grade silicone is uncommon. ISO 10993 biocompatibility testing does not rule out individual sensitivities.
Residual manufacturing or packaging contaminants
No documented cases of heavy metals, phthalates, or other leachables detected in Lunette cups post-manufacture. Initial boiling and rinsing further minimize any theoretical residue risk.
Loss of suction or structural failure if material weakens
Excessive heat exposure (autoclaving at high pressure without manufacturer approval) or prolonged sunlight storage can degrade silicone elasticity and reduce the seal integrity of the cup.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
