Meluna · Menstrual Cups
Basic Beginner Menstrual Cup Kit - HOT | Meluna USA, Stem / Large / White
Lower concern, menstrual cups are inherently low-risk, but Meluna's PFAS stance remains undisclosed.
Meluna menstrual cups are made from medical-grade TPE, a non-Teflon-family coating elastomer not typically formulated with PFAS. The product category (internal silicone/elastomer cups) has no inherent use-case for water-resistance or nonstick coatings that would drive PFAS.

The full breakdown
What it's made of and why it matters
Meluna cups are manufactured from medical-grade thermoplastic elastomer (TPE), a synthetic rubber polymer selected specifically for menstrual products because it resists degradation, does not absorb fluids, and has minimal leaching propensity compared to lower-grade plastics. TPE is non-porous and non-absorbent, meaning it does not harbor bacteria in its structure or release chemical additives into bodily fluids during typical use. The material is inherently safer than silicone alternatives in terms of off-gassing risk, though it requires proper cleaning protocols to prevent biofilm.
The brand's record and disclosure
Meluna has not published explicit safety certifications (FDA, CE, or third-party testing statements) on product pages, nor has the company issued public statements on PFAS presence or absence. The brand does not advertise material sourcing audits or manufacturing transparency beyond basic product descriptions. No safety recalls, contamination reports, or regulatory violations are on record for Meluna menstrual cups. The company's silence on PFAS stance is a transparency weakness rather than evidence of contamination.
How it compares in its category
Medical-grade TPE cups (Meluna, Yuuki, some Eve models) sit at the safer end of the menstrual cup spectrum compared to lower-cost silicone or unspecified elastomer products. Silicone alternatives (Diva Cup, Lunette) have published FDA submissions and material specs; TPE products lag in public disclosure but offer equivalent or lower migration risk due to material chemistry. Menstrual cups overall carry far lower chemical exposure risk than disposable pads or tampons, which may contain dioxins, fragrance allergens, and pesticide residues.
If you buy it
Wash thoroughly with warm water and mild soap before first use and after each cycle; do not use hot water above 75°C (167°F) as prolonged heat can degrade TPE over time. Inspect the cup monthly for visible cracks, discoloration, or odor changes; replace after 5-10 years of use or if integrity is compromised. Store in a breathable cloth pouch (not sealed plastic) to prevent mold; do not autoclave or boil intensely. If you experience irritation or allergic response, discontinue use and consult a gynecologist.
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.”
TPE leaching (additives/plasticizers)
Medical-grade TPE is formulated to minimize migration, but independent lab testing of this specific Meluna product is not publicly available. Leaching risk is substantially lower than conventional soft plastics but cannot be ruled out without third-party certification.
Bacterial biofilm/infection risk if mishandled
Menstrual cups in general carry low but real risk of bacterial overgrowth if stored wet, not cleaned thoroughly, or if internal tears develop. This is a use and maintenance issue, not a material defect, but is relevant to product safety.
Allergic sensitization or irritation from material or additives
Individual sensitivity to TPE formulations is rare but documented in clinical literature. Meluna does not disclose full additive lists (colorants, stabilizers, cure agents), so cross-reactivity cannot be ruled out for sensitive users.
Stem material degradation or breakage
The stem (removal aid) is also TPE and subject to repeated mechanical stress; no field failure data is publicly available, but stem breakage during removal has been reported anecdotally for some brands in this category. Meluna offers stem variants (ball, no-stem, classic) to mitigate this.
Dye or colorant leaching (white variant)
White TPE cups typically use titanium dioxide or similar approved colorants. No reports of dye migration or staining issues are on record for Meluna white cups; risk is lower than for pigmented variants.
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.
