Meluna Menstrual Cup
Lower concern, silicone cups have no inherent PFAS need, but brand offers no explicit assurance.
Meluna menstrual cups are made from medical-grade silicone or TPE elastomers, materials that do not typically require PFAS coatings for function. The brand does not publicly disclose PFAS testing or make PFAS-free claims.

The full breakdown
What it's made of and why it matters
Meluna cups are manufactured from medical-grade silicone or TPE (thermoplastic elastomer) blends, both non-porous materials designed to resist bacterial colonization and degradation from repeated steam sterilization. Unlike latex or rubber, silicone does not leach plasticizers or degrade into microparticles under normal menstrual-cycle temperatures (body heat plus occasional boiling). The material itself is chemically inert and approved for sustained vaginal contact by medical device standards in the EU and US.
The brand's record and disclosure
Meluna holds CE certification as a medical device (Class II in EU), which requires manufacturing and material safety documentation, though the brand does not publicly disclose detailed chemical testing results or third-party lab reports on their website. The company has not faced documented recalls or safety warnings related to chemical leaching, allergic reactions, or material degradation in the public domain. Notably, Meluna does not explicitly certify that their products are PFAS-free, despite silicone's lack of inherent need for PFAS; this silence is typical among menstrual cup manufacturers but limits independent verification.
How it compares in its category
Meluna is among the longer-established brands in the menstrual cup market and occupies the middle ground: medical-grade silicone cups (Meluna, Saalt, Lunette) generally carry fewer documented chemical hazards than budget latex or rubber alternatives, but offer no greater transparency than peer brands. Cups marketed as 'hypoallergenic' or 'medical-grade' have no legal distinction; Meluna's CE mark is a regulatory credential, not a chemical purity guarantee. Most competitors (Saalt, Lunette, DivaCup) similarly lack public PFAS commitments.
If you buy it
Boil or steam sterilize between cycles (silicone withstands 100°C repeatedly); do not use bleach, as it can degrade the surface over time and introduce residues. Replace every 5 years or if the silicone becomes sticky, visibly discolored, or develops odor that does not clear after cleaning, these are signs of material breakdown. Store in a breathable cloth pouch (not sealed plastic) to avoid mold growth. If you experience vaginal irritation, patch-test a new cup (some rare cases of silicone sensitivity are documented, though uncommon).
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 breakdown
Medical-grade silicone is durable but can become sticky, discolored, or develop odor after 5+ years or if exposed to harsh chemicals (bleach, oil-based lubricants). Meluna does not publicly specify expected lifespan or degradation markers, leaving users to self-assess replacement timing.
Bacterial or fungal overgrowth from improper storage/cleaning
Any menstrual cup stored in a sealed plastic container or not air-dried can accumulate bacteria or mold; Meluna's packaging does not emphasize breathable storage, though user guides mention boiling. This is a maintenance issue, not a material defect, but brand guidance could be clearer.
Allergic or irritant reactions to silicone or TPE blend
No recalls or widespread complaints of silicone allergy from Meluna specifically are documented in public records. Rare individuals with silicone sensitivity exist, but incidence is extremely low; Meluna does not disclose whether their TPE blends include additives (colorants, thickeners) that could provoke irritation in sensitive users.
Microplastic shedding from cup surface
Medical-grade silicone does not fragment into microparticles under normal use (body temperature, menstrual fluid exposure). If the cup develops visible tears or pitting, microscopic fragments are theoretically possible, but no documented cases exist for Meluna cups.
Insufficient disclosure on cup color dyes and additives
Meluna offers cups in multiple colors (clear, pink, black, etc.); the brand does not publicly disclose the source or chemical composition of pigments or processing additives used in colored silicone. FDA-approved colorants are standard, but third-party verification is absent.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 75% 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.
