Menstrual Cup Saalt
Lower PFAS concern, silicone menstrual cups lack typical PFAS application pathways, but brand silence on material sourcing limits certainty.
Saalt (Cora) menstrual cups are made from medical-grade silicone, a material not inherently prone to PFAS contamination, unlike nonstick cookware or water-resistant textiles. The brand does not publicly disclose PFAS testing or sourcing details.

The full breakdown
What it's made of and why it matters
The Saalt cup is constructed from medical-grade silicone, a polymer chain that does not naturally contain plasticizers, BPA, or phthalates by design. Medical-grade silicone undergoes higher purity standards than generic silicone and resists degradation during repeated sterilization (boiling, autoclaving). Unlike thermoplastics such as polypropylene or polycarbonate, silicone does not leach estrogen-mimicking chemicals when exposed to heat or body fluids, making it chemically inert in normal use.
The brand's record and disclosure
Saalt (under parent company Cora) does not publish detailed supplier transparency reports or third-party material certifications (e.g., USP Class VI, ISO 10993 biocompatibility testing reports) on its public website. The brand has not faced documented recalls or safety violations related to chemical contamination. Absence of disclosure on manufacturing origin and quality audits limits independent verification, though medical-grade silicone itself is a low-risk category.
How it compares in its category
Menstrual cups made from medical-grade silicone (Saalt, Lunette, DivaCup) carry the same inherent safety profile and are generally safer than disposable pads or tampons in terms of chemical exposure. Some competitors (notably Lena, Lumma) publish biocompatibility test results openly; Saalt does not, which is a transparency weakness but not a chemical hazard indicator. The silicone material itself is at the safer end of the menstrual product spectrum.
If you buy it
Boil the cup for 5-10 minutes before first use and between cycles to sterilize; avoid prolonged exposure to direct flame (steam or water bath preferred). Store in the included breathable pouch, not in sealed plastic, to prevent bacterial growth in damp conditions. Replace if silicone becomes sticky, brittle, or visibly discolored, typically after 5-10 years of regular use. Do not use oil-based lubricants; water-based lubricant is safe and improves insertion comfort.
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 is chemically stable and does not leach known toxic compounds during normal use, boiling, or contact with body fluids. No recalls or adverse events linked to Saalt silicone degradation are on record.
Bacterial or mold colonization
If stored damp in a sealed container, silicone's porous surface can harbor biofilms; risk is mitigated by air-drying before storage and regular boiling. This is a hygiene issue, not a chemical hazard, but worth noting for users in high-humidity climates.
Allergen response to silicone itself
True silicone allergy is rare but documented in some individuals; medical-grade formulations minimize impurities that trigger reactions. Users with silicone sensitivity should patch-test or consult a gynecologist before full use.
Coatings or adhesives in assembly
Saalt cups have no reported coatings, dyes, or adhesive seams that introduce additional chemical exposure. The stem is silicone throughout, not a separate glued component, reducing assembly-related hazard sources.
Heavy metals in pigmentation
The translucent or colored silicone body is not tested publicly for lead or cadmium in the available information; however, medical-grade silicone pigments are typically non-toxic. Without published test data, this remains unverified but unlikely given material standards.
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.
