Lunette Reusable Menstrual Cup 25mL Purple 1
Lower-concern product; medical-grade silicone is not a known PFAS vector, but brand offers no transparency.
Lunette menstrual cups are made from medical-grade silicone, a material not typically associated with PFAS contamination. The brand does not publicly claim PFAS-free status or provide third-party verification. No public lab testing or recalls linked to PFAS have been identified for this product.

The full breakdown
What it's made of and why it matters
The Lunette cup is manufactured from medical-grade silicone, a synthetic polymer that does not naturally contain or leach phthalates, BPA, or BPS. Medical-grade silicone is inert at body temperature and has a long history of safe use in internal medical devices. The 25mL size and purple colorant are the only variables; silicone pigments in reputable menstrual cups are typically approved colorants rather than heavy-metal-laden azo dyes. No known issues with degradation or leaching have been documented for Lunette cups in public databases.
The brand's record and disclosure
Lunette does not publish detailed PFAS or chemical transparency reports on their website or product labeling, which is a disclosure gap common to many smaller menstrual-cup brands. The company is not known to have faced product recalls or safety controversies in the menstrual-cup market. Lunette has claimed compliance with FDA guidelines for menstrual cups, though they do not independently third-party test or publish full material certifications. The silence on PFAS is notable but not unusual for silicone-based manufacturers in this category.
How it compares in its category
Menstrual cups made from medical-grade silicone (Lunette, Saalt, Flex, Diva Cup) carry lower chemical risk profiles than disposable tampons and pads, which may contain undisclosed fragrances, bleach residues, and synthetic materials. Cups avoid the microplastic and degradation issues inherent to plastic applicators and single-use products. Lunette is positioned mid-range in terms of transparency; premium competitors like Saalt publish fuller ingredient and sourcing data, while many budget alternatives provide minimal safety information. All medical-grade silicone cups are functionally equivalent in contamination risk if properly cleaned and stored.
If you buy it
Boil the cup in water for 5-10 minutes before first use and after each cycle to sterilize. Do not expose to temperatures above 80°C or bleach, as silicone is stable but dyes may degrade. Inspect the cup monthly for tears, discoloration, or softening; replace every 2-3 years or sooner if walls become sticky or odor persists despite cleaning. Store in a breathable pouch in a cool, dry place to prevent mold or bacterial biofilm growth during non-use.
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.”
Bacterial or mold growth during storage
Medical-grade silicone itself does not support microbial growth, but trapped moisture in storage or between the cup walls and stem can foster anaerobic bacteria or Candida if the cup is stored damp or in a sealed container. Proper air-dry and breathable pouch storage mitigate this.
Colorant leaching or migration
Medical-grade silicone colorants are inert at body pH and temperature. No documented cases of dye migration or skin staining from Lunette cups. Purple pigment quality depends on supplier compliance, which Lunette does not publicly disclose.
Silicone degradation and leaching
Medical-grade silicone is chemically stable and does not degrade or leach oligomers at normal body temperature. Long-term data (5+ years) on Lunette cups specifically is limited in public literature, but the material class has a strong safety record in implants and medical devices.
Heavy metals in purple colorant
No recalls or regulatory findings of lead, cadmium, or antimony in Lunette cups. Reputable medical-device silicone suppliers avoid azo dyes and heavy-metal pigments, though Lunette does not publish pigment specifications.
Allergic reaction to silicone or additives
Silicone allergy is rare but documented in medical literature for about 1 in 10,000 users of silicone implants. Cross-reactivity to residual catalysts or stabilizers in medical-grade silicone is theoretically possible but not reported in menstrual-cup users.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
