Lunette Menstrual Cup - Violet
Lower-concern product; silicone menstrual cups rarely involve PFAS, but brand makes no explicit commitment.
Lunette Menstrual Cup is made from medical-grade silicone, a material not typically associated with PFAS use in manufacturing. Menstrual cup products generally fall outside categories prone to fluorochemical coatings (non-stick, water-repellent, grease-resistance).

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 plasticizers, and tolerates repeated sterilization. Unlike lower-grade silicone or elastomers, medical-grade silicone undergoes stringent biocompatibility testing and is designed for prolonged internal contact. The violet colorant is integrated into the silicone matrix during manufacturing rather than applied as a surface coating, reducing risk of dye migration or surface wear exposing underlying materials.
The brand's record and disclosure
Lunette publishes material certifications (FDA cleared as Class II medical device; ISO 4862 biocompatibility standard) and maintains transparent ingredient labeling, though the company does not make explicit public statements about PFAS-free formulation or supplier audits. No product recalls, contamination incidents, or third-party safety violations are documented for this cup. The brand's Scandinavian manufacturing origin typically correlates with stricter material sourcing practices, though this is not independently verified for all suppliers.
How it compares in its category
Menstrual cups occupy a lower-risk category than many reusable period products because they avoid absorbent materials that can trap bacteria or mold. Lunette is mid-market; competing medical-grade brands (Diva Cup, Saalt) share identical material safety profiles. Compared to disposable pads and tampons, cups eliminate concerns about bleach residue, dioxins from chlorine processing, and rayon/absorbent polymer additives, though cup-specific hazards (insertion/removal injury, toxic shock if left too long) are behavioral rather than chemical.
If you buy it
Sterilize by boiling in water for 5-10 minutes between cycles; do not use bleach or harsh chemicals that can degrade silicone over time. Replace the cup every 5 years or sooner if you notice visible cracks, cloudiness, or persistent odor after cleaning. Empty and rinse every 8-12 hours during use to prevent bacterial overgrowth and toxic shock risk. Store dry in a breathable pouch, not sealed in plastic, to avoid moisture retention and mold.
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 surface cracking
Medical-grade silicone resists degradation under normal use, but repeated boiling, exposure to oils, or scratching can compromise integrity over years. Visible cracks create crevices where bacteria may colonize; no recalls have been documented, but users should inspect cups regularly.
Bacterial colonization if poorly maintained
Silicone itself does not harbor bacteria, but trapped blood and tissue in the cup or stem can foster growth if not rinsed thoroughly or if the cup is stored wet. This is a maintenance issue, not a material hazard, but prolonged colonization increases toxic shock syndrome risk.
Colorant leaching or migration
The violet dye is integrated into the silicone polymer matrix rather than surface-applied, and no reports of color bleeding, staining, or dye migration into menstrual fluid exist. Medical-grade silicone manufacturing standards require color stability testing.
Heavy metals in pigments
Medical-device regulations and ISO biocompatibility testing mandate screening for cadmium, lead, and other metals in colorants. No independent lab testing of Lunette cups for heavy metals has been published, but the material class and regulatory status provide reasonable assurance.
Insertion and removal injury
This is behavioral, not chemical, but worth noting: improper insertion, removal during heavy flow, or use with insufficient lubrication can cause vaginal micro-tears that increase infection risk. The product itself poses no chemical hazard here.
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.
