DIVA Cup Model 2
Lower-concern menstrual cup; silicone construction and PFAS-free commitment make it a reasonable choice.
The DIVA Cup Model 2 is made from medical-grade silicone with no Teflon-type coating or intentional Teflon-family coating coatings. Aisle has publicly committed to PFAS-free materials and carries MADE SAFE certification, which independently verifies absence of harmful chemicals including PFAS.
Brand says: “DIVA Cup is made from medical-grade silicone and is PFAS-free; Aisle publishes PFAS transparency information”

Why this grade
Category baseline
period care is a category where PFAS exposure is more common.
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Diva Cup Model 2 is constructed from medical-grade silicone, a synthetic polymer engineered for biocompatibility and repeated sterilization. This material does not contain Teflon-type coating, phthalates, BPA, or other endocrine disruptors commonly found in lower-cost alternatives. Medical-grade silicone is chemically inert when in contact with body fluids and does not leach substances under normal use conditions, even during repeated boiling sterilization.
The brand's record and disclosure
Aisle explicitly markets the Diva Cup as PFAS-free and has maintained this commitment publicly. The company provides material documentation and does not have recorded product recalls related to chemical contamination or degradation. Aisle has not faced major regulatory enforcement or substantiated toxicity complaints in public databases for this product line.
How it compares in its category
Menstrual cups as a category carry significantly lower chemical risk than single-use pads and tampons because silicone does not require bleaching agents, adhesives, fragrances, or absorbent gels. The Diva Cup Model 2 is positioned at the premium end of the market and competes directly with other medical-grade silicone cups; it does not use cheaper thermoplastic rubber or lower-grade silicone that can degrade or leach over time.
If you buy it
Sterilize by boiling for 5-10 minutes before first use and monthly thereafter; silicone tolerates this well. Inspect the cup for tears, cracks, or discoloration annually and replace if found, though the product typically lasts 5-10 years with proper care. Rinse thoroughly with water between uses and avoid oil-based lubricants, which can degrade silicone; water-based lubricants are safe. Store in a breathable cloth pouch when not in use to prevent moisture trapping and odor buildup.
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 over time
Medical-grade silicone used in the Diva Cup Model 2 is chemically stable and does not degrade under normal use or sterilization; no published reports of degradation, leaching, or breakdown with this product.
Bacterial growth and biofilm
If not rinsed thoroughly or boiled monthly, any menstrual cup can harbor bacteria in microscopic crevices; this is a maintenance issue, not a material defect. The Diva Cup's smooth surface is easier to clean than textured alternatives.
Allergic reactions or sensitization
Medical-grade silicone is hypoallergenic; no documented cases of allergic contact dermatitis or systemic reactions to the Diva Cup Model 2. Individuals with severe silicone sensitivity (extremely rare) should patch-test before full insertion.
Fragrance or irritant additives
The Diva Cup contains no added fragrances, dyes, or topical irritants; it is an unscented, uncolored product, reducing risk of vulvovaginal irritation common with menstrual pads.
Heat tolerance and steam sterilization
Medical-grade silicone tolerates boiling and autoclave sterilization without degradation, melting, or leaching; the product is explicitly rated for repeated heat sterilization and shows no known issues with this practice.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
