Lunette Reusable Menstrual Cup
Lower-concern product; silicone cups are intrinsically PFAS-unlikely, but brand offers no explicit verification.
Lunette menstrual cups are made from medical-grade silicone, a non-fluorinated elastomer with no known PFAS treatment. The brand does not publicly disclose PFAS testing or make PFAS-free claims, leaving a small verification gap. Silicone's inert nature and intended use (internal, not water-exposed) reduce PFAS exposure risk substantially.

The full breakdown
What it's made of and why it matters
Lunette cups are manufactured from medical-grade silicone, a synthetic polymer chosen specifically for menstrual products because it resists degradation, does not leach chemicals under normal body temperature, and meets FDA standards for internal-use devices. Unlike some plastics, silicone has no known plasticizers (like BPA or phthalates) as functional additives. The lack of any disclosed coating or lining means the body contacts silicone directly, minimizing intermediate materials that could harbor contaminants.
The brand's record and disclosure
Lunette does not publish detailed safety certifications, material testing reports, or explicit PFAS statements on its public materials, which represents a transparency gap relative to some competitors. The brand is registered with the FDA as a Class II medical device but provides minimal post-market safety data to consumers. No product recalls or established safety controversies are on public record. This silence on testing does not indicate a hazard; it reflects incomplete voluntary disclosure.
How it compares in its category
Menstrual cups occupy a narrow safety window because they contact mucous tissue for extended periods. Lunette's medical-grade silicone is comparable to or equivalent to Diva Cup, Saalt, and other mainstream brands using the same material class. Cheaper cups may use lower-grade silicone or thermoplastic elastomers, which carry slightly higher leaching risk under heat. Lunette's positioning at mid-market price with a major brand suggests reasonable quality control, though lack of third-party testing limits certainty.
If you buy it
Boil the cup for 20 minutes before first use and monthly thereafter to remove any residual manufacturing compounds and reduce bacterial load. Do not use bleach or harsh scrubbers; wash with mild soap and water. Replace if silicone becomes sticky, cracked, or discolored. Store in a breathable pouch (not sealed plastic) to prevent mold. Do not autoclave or expose to direct flame. If irritation develops, discontinue and consult a healthcare provider; silicone reactions are rare but possible.
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 or leaching
Medical-grade silicone is chemically inert at body temperature and has no established history of leaching in menstrual cup use. Degradation is cosmetic (discoloration, stickiness) rather than chemical; occurs over years with proper care.
Bacterial or mold contamination
Any reusable menstrual cup can harbor bacteria or mold if not boiled regularly or stored in a sealed, moist environment. This is a user-maintenance issue, not a product defect; proper care (monthly boiling, breathable storage) mitigates risk substantially.
Allergic sensitization or irritation
True silicone allergy is exceedingly rare; irritation reported anecdotally in forums is usually attributable to insertion technique, fit, or pre-existing sensitivities rather than the material itself. No recalls or cluster complaints linked to Lunette silicone.
Manufacturing contaminants (e.g., uncrosslinked oligomers)
Medical-grade silicone can contain trace volatile or semi-volatile oligomers depending on polymerization and quality control. Lunette does not publish extractable testing; boiling before first use reduces this theoretical risk by removing surface compounds.
Dye or pigment toxicity
Lunette cups are available in solid colors (blue, pink, clear). The specific dyes or colorants used are not disclosed; medical-grade silicone typically uses FDA-approved colorants, but third-party testing would be needed to verify for this product specifically.
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.
