AllMatters Menstrual Cup
Lower PFAS concern; silicone cups carry minimal intrinsic risk, but no public brand transparency.
AllMatters menstrual cups are made from medical-grade silicone, a material class not typically formulated with PFAS. The brand does not publicly disclose PFAS testing or stance. No third-party certification or lab data confirming absence is available in public records.

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
AllMatters Menstrual Cup is constructed from medical-grade silicone, a synthetic polymer engineered for biocompatibility and repeated contact with mucous membranes. Medical-grade silicone does not contain BPA, phthalates, or plasticizers that leach into body fluids during normal use. The material resists degradation from body heat and menstrual fluid chemistry, meaning chemical migration into the cup's interior or user tissues remains theoretical rather than documented in this product class.
The brand's record and disclosure
AllMatters is a Swedish brand with modest public safety documentation available; the company does not publish detailed material sourcing, heavy-metal test reports, or PFAS statements on its website or standard marketing channels. No product recalls, contaminant incidents, or regulatory warnings have been recorded for this specific cup. The brand's silence on PFAS and third-party testing differs from premium competitors (Saalt, DivaCup) who voluntarily publish test certificates, but absence of controversy is not absence of testing.
How it compares in its category
Menstrual cups occupy a safer chemical space than disposable pads or tampons, which carry microplastic fibers, pesticide residues, and bleach byproducts. AllMatters sits mid-tier: more transparent certifications and test data exist for brands like Saalt, Lunette, and DivaCup, but AllMatters' medical-grade silicone formula is chemically equivalent to these competitors. The main differentiator is brand disclosure, not material safety.
If you buy it
Boil the cup before first use and wash with plain water or mild soap after each cycle; silicone tolerates 120°C boiling without degradation. Store in a breathable cotton pouch, not sealed plastic, to prevent bacterial growth and odor. Replace every 5-10 years or if the material becomes sticky, cracked, or discolored. Avoid bleach, alcohol-based cleansers, and oil-based lubricants, which can degrade silicone over time.
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 leachables
Medical-grade silicone used in menstrual cups does not leach oligomers or toxic breakdown products under normal vaginal pH, temperature, or wear duration. No documented cases of silicone-related irritation or leaching have been recorded for AllMatters or comparable brands.
Bacterial or fungal growth
Improper drying or storage in humid, sealed conditions can allow biofilm formation on the cup interior. This is a maintenance issue rather than a product defect, but users who do not clean thoroughly between cycles face yeast or bacterial overgrowth risk.
Heavy metals in silicone formulation
AllMatters does not publicly disclose heavy-metal assays for lead, cadmium, or arsenic in its silicone. Medical-grade silicone manufacturers typically do not introduce these elements intentionally, but third-party verification is absent from available documentation.
Color pigment toxicity
The cup is offered in multiple colors; if pigments are synthetic dyes or iron oxides, migration into menstrual fluid is negligible due to silicone's low permeability and brief contact time. No adverse events linked to cup color have been reported.
Allergic sensitization to silicone
True silicone allergy is rare but documented in medical literature. Individuals with known sensitivity to silicone (e.g., from breast implants, catheters) should patch-test or consult a provider before use. AllMatters does not address this population in available guidance.
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.
