Lunette Menstrual Cup
Lower-concern choice; silicone menstrual cups carry minimal PFAS risk by material class, but Lunette does not publicly address PFAS.
Lunette cups are made from medical-grade silicone, a material not typically formulated with PFAS. Silicone is used in medical devices and is not a known vector for PFAS contamination the way Teflon-family coating coatings or waterproofing treatments are.

The full breakdown
What it's made of and why it matters
Lunette cups are constructed from medical-grade silicone, a synthetic elastomer chosen specifically for biomedical devices because it resists degradation, does not leach known endocrine disruptors like BPA, and tolerates repeated heat sterilization without breaking down. Silicone is chemically stable across the pH and temperature ranges of normal menstrual use (body temperature and mild cleaning). Unlike latex or lower-grade plastics, medical-grade silicone does not off-gas volatile organic compounds or release phthalates into the body.
The brand's record and disclosure
Lunette has been in the menstrual cup market since 2005 and maintains FDA clearance as a medical device in the United States, which requires demonstrated safety in materials and design. The brand does not publicly address PFAS content in marketing or technical documentation, which is not uncommon for smaller manufacturers. No recalls, contamination incidents, or quality control failures are on public record for Lunette cups. The company's silence on PFAS is a transparency gap rather than evidence of a problem, since the silicone material class itself carries minimal PFAS risk.
How it compares in its category
Lunette sits in the mainstream segment of medical-grade silicone cups, alongside brands like DivaCup and OrganiCup; all three use similar material standards. Cheaper alternatives (unbranded silicone or lower-grade elastomers) may have less rigorous quality control. Lunette's FDA clearance and two-decade history give it stronger third-party validation than many competitors. Pricing and cup shape are product-level differences, but material safety profiles across major brands are essentially equivalent.
If you buy it
Sterilize the cup before first use and monthly by boiling in water for 5-10 minutes; avoid bleach or microwave sterilizers which can degrade silicone over time. Inspect the cup visually and by touch each cycle for tears, pitting, or discoloration; replace if the material becomes sticky, brittle, or develops persistent odor. Do not expose to direct sunlight for extended periods or store in very hot environments (e.g., car in summer), as heat accelerates silicone aging. Most users report 5-10 years of use before noticeable degradation, though individual biology and care practices vary.
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 degradation and leaching
Over many years of repeated thermal stress and oxidative exposure, medical-grade silicone can develop micro-cracks or surface degradation. Degraded material may shed particulate or allow residual manufacturing compounds to leach; risk is low with proper care and replacement every 5-10 years.
Bacterial contamination if improperly cleaned
Menstrual cups require complete air drying between uses; failure to dry or sterilize correctly can allow bacterial biofilm growth. This is a use-and-maintenance issue, not a material defect, but contamination could cause infection or toxic shock syndrome if not prevented.
Heavy metals or pigment contaminants in colored variants
Lunette offers colored cups; no published testing or recalls indicate heavy metal contamination in colorants. Medical-grade silicone suppliers are typically subject to supplier audits, but the company does not disclose third-party testing of dyes or pigments.
Residual manufacturing compounds or uncrosslinked oligomers
All new silicone medical devices can release trace amounts of oligomeric siloxanes during first use; Lunette recommends boiling before use, which reduces this risk substantially. No complaints or adverse event reports attributing systemic toxicity to Lunette cups are on record.
Allergic sensitization to silicone
Medical-grade silicone is hypoallergenic and rarely triggers contact dermatitis in the general population. Individuals with documented silicone sensitivities are rare and should consult a physician before use, but no specific adverse reactions to Lunette cups have been documented.
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.
