Flex Menstrual Cup
Lower PFAS concern; silicone cups are inherently low-risk, though OrganiCup has not publicly disclosed PFAS testing.
OrganiCup Flex Menstrual Cup is made from medical-grade silicone, a material with no inherent PFAS Teflon-family coating backbone and no typical water-repellent coating or nonstick coatings that would introduce PFAS.

The full breakdown
What it's made of and why it matters
OrganiCup is manufactured from medical-grade silicone, a non-porous elastomer with no added plasticizers (unlike cheaper cups that may contain phthalates) and no synthetic rubber fillers. Silicone is inert at body temperature and does not degrade into leachable monomers under normal use. Unlike latex alternatives, it carries no natural rubber allergen risk and is hypoallergenic by design.
The brand's record and disclosure
OrganiCup holds OEKO-TEX Standard 100 certification and FDA 510(k) clearance as a medical device, indicating third-party testing for harmful substances. The brand publishes material safety data and has consistently communicated product composition. No product recalls, contamination incidents, or adverse event reports have been documented in public databases. The company has not yet publicly released PFAS testing results, though silicone cups are inherently unlikely to contain intentional Teflon-family coating additives.
How it compares in its category
Medical-grade silicone cups (OrganiCup, Saalt, Lena) are the safest category of menstrual products and significantly lower-risk than disposable pads and tampons, which may contain bleaching byproducts, pesticide residues, and rayon fibers. Compared to cheaper silicone knockoffs sold online without certification, OrganiCup's regulated manufacturing and third-party testing reduce leachate risk. Natural rubber latex cups pose allergen exposure risks absent here.
If you buy it
Boil the cup before first use and between cycles to remove any manufacturing residue. Silicone tolerates boiling (100°C) without degradation. Store in the included breathable pouch, not airtight containers, to prevent bacterial overgrowth. Inspect the cup quarterly for tears, cloudiness, or sticky residue; discard and replace after 10 years or upon visible damage. Avoid prolonged exposure to direct sunlight or oils that can degrade silicone over decades.
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 does not release harmful oligomers at body temperature or during boiling. No published studies have documented toxic leaching from certified silicone menstrual cups under normal use conditions.
Bacterial contamination from cup or storage
Risk is minimal if boiled before use and stored dry, but airtight storage or infrequent washing can harbor Staphylococcus aureus or other vaginal flora. This is a user-maintenance issue, not a product defect.
Allergic contact dermatitis or vulvovaginitis
OrganiCup is hypoallergenic and OEKO-TEX certified for absence of irritants. Individual sensitivity is rare but possible; reported reactions typically resolve upon discontinuation.
Mold or fungal growth in stored cup
Silicone itself does not support mold, but storage pouches or cups with visible damage can trap moisture. Proper air-drying and breathable storage eliminate this risk.
Heavy metals in pigments (if cup is colored)
OrganiCup's colored variants (rose, purple, pink) use FDA-compliant colorants tested under OEKO-TEX certification. No lead, cadmium, or arsenic contamination has been documented.
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.
