Package Free Shop Soft Menstrual Cup Duo Pack
Lower PFAS concern due to silicone material, but brand transparency on PFAS absent.
Saalt menstrual cups are made from medical-grade silicone, a material not typically associated with PFAS. However, the brand does not publicly disclose PFAS testing or make any explicit PFAS-free claims.

The full breakdown
What it's made of and why it matters
Saalt Soft cups are constructed from medical-grade silicone, a synthetic polymer with high thermal stability and minimal leaching profile compared to plastics or coated metals. Medical-grade silicone is inert across typical body temperatures and does not degrade into microplastics under normal vaginal use. The material contains no BPA, phthalates, or latex, making it chemically safer than disposable alternatives and many competing reusable cups made from lower-grade silicone or TPE blends.
The brand's record and disclosure
Saalt provides minimal public disclosure on PFAS testing or third-party certification of its menstrual cups; the brand does not publish material safety data sheets or independent lab results on heavy metal content. No documented safety recalls or complaints specific to Saalt cups have been published by the FDA or consumer databases. The brand markets sustainability and body safety but does not address manufacturing chemical inputs or fluorine-based additives in coating or lubricants.
How it compares in its category
Saalt Soft sits in the mid-to-premium segment of reusable menstrual cups. Its medical-grade silicone is comparable to or exceeds competitors like Lunette and DivaCup in material purity; some competitors (e.g., Lena) provide more transparent third-party testing. The duo-pack format reduces per-unit cost but does not change material safety profile. Reusable cups as a category eliminate the microplastic and chemical exposure risks of tampons and pads.
If you buy it
Rinse the cup in cool water before first use. Wash with mild soap between periods and air dry completely. Boil in water for 5-10 minutes monthly or follow brand guidance to avoid bacterial biofilm. Replace if the silicone develops tears, pitting, or persistent odor (typical lifespan 5-10 years). Do not use if you have a latex allergy, though medical-grade silicone is latex-free; if you have metal sensitivities, note that the cup may contain trace metals in the silicone batch.
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.”
Heavy metals in silicone batch or additives
Medical-grade silicone can contain trace amounts of platinum, tin, or other catalysts used in manufacturing. Saalt does not publish heavy metal testing results, so no contamination has been documented, but the brand's silence on this is a data gap.
Bacterial growth or biofilm if poorly maintained
Silicone texture can harbor bacteria if not cleaned thoroughly between insertions or if dried with residual moisture. This is a hygiene issue, not a material defect, and is mitigated by boiling or antiseptic cup washes per instructions.
Degradation of silicone over time or with heat
Medical-grade silicone is thermally stable to well above normal boiling and does not show brittleness or off-gassing in published studies. No recalls or field reports of cup failure or leaching after years of use have been documented for Saalt or similar medical-grade products.
Fragrance or dye allergens
Saalt cups are clear or opaque without added pigments or fragrances. No formaldehyde releasers or azo dyes are used in the silicone itself.
Incomplete disclosure of coating lubricants or release agents
Menstrual cups may be coated or lubricated with silicone oils or waxes to ease insertion. Saalt does not publicly detail these additives or their PFAS-free status, creating uncertainty about potential fluorinated mold-release compounds.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
