Menstrual Cup Saalt
Lower PFAS concern; silicone menstrual cups are not a typical PFAS-risk product category.
Saalt menstrual cups are made from medical-grade silicone, a material not typically associated with PFAS contamination (unlike Teflon-family coating coatings or water-repellent coating treatments).

The full breakdown
What it's made of and why it matters
Saalt cups are made from medical-grade silicone, a synthetic elastomer designed for biomedical implants and long-term body contact. This material resists degradation, does not leach BPA or phthalates, and is chemically inert across normal menstrual-use temperatures (body heat, washing water up to about 80 C). Unlike latex or rubber alternatives, silicone does not contain latex proteins that trigger allergic reactions, and it is non-porous, reducing bacterial harborage.
The brand's record and disclosure
Aisle (Saalt's parent company) provides product material specifications on its website and has not faced public recalls or safety violations on record for this menstrual cup. The brand does not explicitly advertise independent third-party testing (e.g., FDA clearance or ISO 10993 biocompatibility certification), though medical-grade silicone itself is a regulated material class. No documented controversies or user injury reports are established in public safety databases for Saalt cups.
How it compares in its category
Menstrual cups in general carry lower chemical hazard burden than single-use pads or tampons (which may contain chlorine residues, synthetic fragrances, or rayon fibers). Silicone cups are comparable to or safer than cups made from elastomer blends or latex. Saalt's material choice and price point place it in the mainstream medical-silicone segment, alongside competitors like Lunette and DivaCup, with no substantive safety differentiation reported.
If you buy it
Wash thoroughly with unscented soap before first use and after each cycle; boil for 5-10 minutes monthly or per instructions to prevent biofilm buildup. Do not expose to extreme heat (dishwasher or prolonged direct flame) as silicone can degrade under sustained high temperature, though normal boiling is safe. Replace if the cup becomes visibly sticky, cracked, or discolored; medical-grade silicone typically lasts 5-10 years with proper care. Store in a breathable pouch, not airtight containers, to avoid moisture trapping.
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.”
Bacterial or mold growth from improper cleaning/storage
Silicone itself is non-porous and resistant to microbial colonization, but if the cup is not fully dried or boiled regularly, biofilm can accumulate in folds or under the stem. This is a user-maintenance hazard, not a product defect, and is preventable with standard hygiene practice.
Silicone degradation from repeated thermal stress
Medical-grade silicone is stable under normal menstrual-use conditions (body temperature, periodic boiling to 100 C). No documented degradation or leaching of silicone oligomers into menstrual fluid is reported for Saalt or similar cups in published safety assessments.
Allergic sensitization to silicone
True IgE-mediated silicone allergy is extremely rare and not substantiated in medical literature. Some users report localized irritation (vulvitis, contact dermatitis) which is typically attributed to cup fit, menstrual irritation, or inadequate cleaning rather than silicone toxicity.
Vaginal colonization or toxic shock syndrome (TSS) risk
Menstrual cups do not contain rayon or superabsorbent polymers linked to TSS in tampons. Risk is primarily behavioral (wearing >12 hours, improper insertion causing microabrasion, or pre-existing vulvovaginal infections). Saalt provides clear wear-time and care guidance; TSS risk is not elevated versus other silicone cups if instructions are followed.
Leaching of colorants or additives from cup material
Medical-grade silicone typically contains only copolymers and inert fillers; no dyes, heavy metal pigments, or softening agents are standard. Saalt does not publish detailed additive disclosures, but no leaching incidents or contamination reports are documented for this product.
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.
