DIVA Cup Model 2
Lower PFAS concern, medical-grade silicone is a safer material class, but brand offers no explicit transparency.
Diva Cup Model 2 is made from medical-grade silicone, which has no inherent PFAS risk profile and is not typically treated with fluorochemical coatings. The brand does not publicly disclose PFAS testing or make PFAS-free claims, so assurance rests on material composition rather than verified testing.

The full breakdown
What it's made of and why it matters
The Diva Cup Model 2 is manufactured from medical-grade silicone, a synthetic rubber polymer that does not contain BPA, phthalates, or latex. Medical-grade silicone is specifically formulated for biocompatibility and internal body contact, undergoing stricter material standards than consumer-grade silicone. This material class is inherently resistant to leaching under normal vaginal pH and temperature conditions, and does not degrade when exposed to common menstrual-cycle moisture and body heat.
The brand's record and disclosure
Diva Inc. maintains FDA clearance as a Class II medical device and publishes basic material composition (medical-grade silicone) on its website and product packaging. The company has not voluntarily disclosed independent third-party testing results, toxicology reports, or PFAS testing despite industry movement toward transparency. No product recalls, safety alerts, or documented contamination incidents are on record for the Diva Cup Model 2 since its market entry. The brand's silence on PFAS and other advanced safety certifications (e.g., ISO 10993 biocompatibility detail) reflects a compliance-minimum rather than transparency-forward posture.
How it compares in its category
Menstrual cups made from medical-grade silicone are among the safest internal period products on the market compared to tampons and pads, which carry risks from bleach residues, dioxins, and synthetic fiber shedding. The Diva Cup sits in the mainstream premium segment; competitors like Saalt, Nixit, and Lunette offer similar silicone formulations with varying disclosure depth. No comparative testing data is publicly available to distinguish silicone purity or leaching profiles between brands, so product choice typically hinges on comfort fit, brand reputation, and price rather than measurable safety differentiation.
If you buy it
Rinse thoroughly with water before first use and after each emptying; do not boil for more than 20 minutes per manufacturer guidance (extended high heat can theoretically stress silicone bonds, though degradation is extremely slow). Replace the cup every 5 years or sooner if you notice surface cracks, discoloration, or persistent odor that cleaning does not resolve. Store in the provided cloth pouch or breathable container when not in use to prevent dust accumulation; avoid prolonged exposure to direct sunlight or extreme heat. If you experience unusual irritation, allergic reaction, or toxic shock symptoms, discontinue use and consult a healthcare provider immediately.
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 microtearing
Medical-grade silicone is durable but can develop microscopic surface tears or stress whitening over years of folding, insertion, and boiling. No documented cases of this causing systemic harm, but compromised surface may increase friction or bacterial colonization risk if left uncleaned.
Bacterial biofilm formation if improperly maintained
Any reusable internal menstrual device carries theoretical risk of pathogenic bacterial or fungal growth if stored wet, cleaned inadequately, or replaced infrequently. Diva Cup is not inherently more or less susceptible than competing silicone cups; risk is user-behavior dependent, not material-dependent.
Latex sensitivity cross-reaction (if present)
Diva Cup is latex-free, so risk to latex-allergic users is absent. No documented instances of cross-reactive protein residues from silicone manufacturing.
Heavy metals or pigment contaminants in silicone compound
Medical-grade silicone is typically additive-free or contains only FDA-approved colorants and stabilizers. No recalls or testing data revealing lead, cadmium, or other heavy metals in Diva Cup products.
Vaginal or cervical trauma from improper use
This is a user-technique issue rather than a material hazard; overly firm insertion, incorrect sizing, or prolonged wear can cause tissue irritation independent of cup composition. The Diva Cup offers two sizes but no personalized fit assessment, relying on self-selection.
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.
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.
