Meluna · Menstrual Cups
Basic Beginner Menstrual Cup Kit - HOT | Meluna USA, Stem / Shorty XL / White
Lower PFAS concern; silicone menstrual cups are generally not a PFAS-risk category, but Meluna does not publicly address PFAS.
Meluna menstrual cups are made from medical-grade silicone, a material class not typically associated with intentional PFAS use. The brand does not publicly disclose PFAS testing or make PFAS-free claims. No lab data or recalls are publicly available.

The full breakdown
What it's made of and why it matters
This cup is manufactured from medical-grade silicone, a thermosetting elastomer that does not contain BPA, phthalates, or latex. Medical-grade silicone is inert at body temperature and resistant to degradation from menstrual fluids and typical cleaning methods (soap, boiling). The material is non-porous and does not support bacterial biofilm growth if cleaned properly between cycles. Unlike latex or plastic alternatives, silicone does not leach hormone-disrupting compounds during normal use.
The brand's record and disclosure
Meluna is a German manufacturer with over two decades in menstrual cup production and holds CE marking for medical device compliance (indicating third-party safety assessment under EU standards). The company does not publicly disclose PFAS testing or a position on PFAS-free manufacturing, though this is not unusual for the category. No product recalls, safety complaints, or contamination reports have been recorded for Meluna menstrual cups in public databases. The brand offers transparent material sourcing information on its website.
How it compares in its category
Menstrual cups occupy a lower-risk category than disposable period products or hormone-releasing devices because they have minimal surface contact with the bloodstream and are external to the uterus. Medical-grade silicone cups (Meluna, Lunette, DivaCup) are functionally equivalent in safety profile; differences are ergonomic and cost-based. The Shorty XL size and stem design are standard variations with no documented hazard differences. Meluna's pricing and reusability make it comparable to premium competitors on safety grounds.
If you buy it
Wash with mild soap and water or dedicated cup cleaner before and after each use; boil for 5-10 minutes at the start and end of each cycle to sterilize. Do not expose to bleach, hydrogen peroxide, or oil-based products, which can degrade silicone over time. Replace every 5-10 years or if you notice cracks, discoloration, or loss of firmness (all indicate material breakdown). Store in a breathable pouch, not airtight containers, to prevent mold growth.
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 leaching
Medical-grade silicone used in menstrual cups is thermally stable and does not degrade at body temperature or during normal boiling. No published studies document leaching of silicone breakdown products into menstrual fluid.
Bacterial growth and toxic shock syndrome (TSS)
TSS risk with menstrual cups is rare but documented in medical literature; risk is comparable to tampons and is primarily a function of wear duration and cleaning, not the cup material itself. Proper daily washing and boiling eliminates the cup as a contamination vector.
Allergic reaction to silicone or additives
Silicone allergy is extremely rare; no case reports specific to menstrual cups exist in medical literature. Medical-grade silicone typically contains minimal additives compared to consumer plastics.
Dye or colorant safety (white variant)
The white colorant in this cup model is not specified publicly, but medical-grade silicone is typically pigmented with titanium dioxide or iron oxides, both of which are inert and approved for internal medical devices. No reports of dye leaching or irritation from colored silicone cups.
Microplastic shedding
Silicone does not fragment into microplastics under normal use conditions; it is a cross-linked polymer that maintains structural integrity. No evidence of particulate release from menstrual cups during wear or cleaning.
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.
