Lunette Menstrual Cup - Blue
Lower PFAS concern; medical-grade silicone menstrual cups are not a typical PFAS application.
Lunette Menstrual Cup is made from medical-grade silicone, a material category with lower inherent PFAS risk compared to Teflon-family coating coatings, water-resistant treatments, or nonstick surfaces.

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Lunette cups are constructed from medical-grade silicone, a thermoset polymer with a long track record in medical implants and devices. Medical-grade silicone does not contain BPA, BPS, or phthalates by formulation standard. The material is chemically inert at body temperature and does not leach additives into menstrual fluid or vaginal tissue when properly manufactured and cleaned.
The brand's record and disclosure
Lunette has maintained consistent product messaging around material safety and does not publish formal third-party test reports or ISO certifications in public documents. The company has no recorded safety recalls or adverse event patterns reported to regulatory bodies. Brand transparency on manufacturing origin and supply-chain testing is limited but does not conflict with stated medical-grade claims.
How it compares in its category
Medical-grade silicone menstrual cups (Lunette, Diva Cup, Saalt) occupy the highest safety tier in the category and pose lower chemical risk than plastic or lower-grade silicone alternatives. Latex cups carry allergy risk; some budget silicone products lack third-party verification of grade. Lunette's design and material are typical of established brands with multi-year user safety history.
If you buy it
Wash with mild soap and water or silicone-safe cleanser before first use and after each cycle. Do not expose to extreme heat (dishwasher heating cycles are acceptable; avoid boiling if possible, though brief boiling is not contraindicated). Replace after 5-10 years or if silicone shows visible degradation, cracks, or permanent deformation. Store dry in a breathable pouch to prevent bacterial growth or odor.
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 particulate shedding
No documented cases of medical-grade silicone menstrual cups shedding microparticles or degrading under normal use. Silicone is a thermoset polymer resistant to mechanical breakdown at body temperature.
Bacterial colonization and infection risk
Risk is behavioral, not chemical: poor cleaning or prolonged storage in moist conditions can allow bacterial biofilm growth on any cup material. Medical-grade silicone itself is non-reactive and does not promote pathogen growth; risk exists for all menstrual cups if hygiene protocol is not followed.
Allergic contact dermatitis or vulvar irritation
Medical-grade silicone is hypoallergenic and does not contain known sensitizing dyes, resins, or accelerators. No established pattern of vulvar or vaginal irritation attributable to Lunette silicone in public reports or user databases.
Heavy metals in pigmentation (blue colorant)
Medical-grade silicone pigments are regulated for medical device use; titanium dioxide and iron oxides (safe inert pigments) are typical. No reports of lead, cadmium, or other toxic metals in menstrual cup colorants from established brands. Lunette does not disclose pigment composition but brand does not appear in safety alerts related to pigment toxicity.
Formaldehyde or volatile off-gassing
Medical-grade silicone does not rely on formaldehyde-releasing resins or chemical crosslinkers that off-gas. Silicone odor at purchase is typical and fades with rinsing; odor is not a hazard marker for this material class.
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.
