AllMatters Full Coverage Cup Kit
Lower PFAS concern for silicone menstrual cups; brand silence on PFAS is typical but unreassuring.
AllMatters makes silicone menstrual cups, a material category with inherently lower PFAS risk compared to coated or treated products. Medical-grade silicone is not a known PFAS application. The brand provides no public PFAS statement, which is common in the period-care category but leaves room for transparency improvement.

Why this grade

period care is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
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 cups are constructed from medical-grade silicone, a high-purity elastomer that does not contain BPA, phthalates, or latex. Silicone's inert cross-linked polymer structure means it does not leach estrogenic compounds or plasticizers during normal use, even when in prolonged contact with menstrual fluid or body heat. The material is non-porous and inherently resistant to microbial colonization compared to lower-grade rubbers or foams.
The brand's record and disclosure
AllMatters is a UK-based menstrual health company with no documented safety recalls or regulatory actions on record. The brand does not publish detailed material sourcing or PFAS testing data on its website or product documentation, which is standard silence in the menstrual cup category but limits independent verification. Third-party certifications (FDA, CE marking) are present but PFAS compliance statements are absent.
How it compares in its category
Medical-grade silicone menstrual cups are among the safest reusable period products available; AllMatters sits in the mainstream safety tier alongside Mooncup and Saalt. Unlike disposable pads or tampons, cups do not shed microfibers and do not require chemical bleaching or dioxin-based processing. The main differentiation is brand transparency on supply chain and PFAS; AllMatters is less forthcoming than some competitors but comparable to most.
If you buy it
Boil cups before first use and monthly thereafter to maintain sterility; silicone remains stable up to 100°C. Store in a breathable pouch, not a sealed plastic bag, to avoid mold growth between cycles. Replace if the cup becomes visibly torn, discolored, or develops persistent odor despite cleaning. Do not use oils or abrasive scrubbers; wash with soap and water or dedicated menstrual cup cleanser.
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 leaching (non-toxic organic compounds)
Medical-grade silicone does not leach BPA, phthalates, or known endocrine disruptors under body-temperature storage. No chemical migration studies on record show toxicologically relevant leachates.
Microbial contamination (bacterial growth)
Improper cleaning or storage in humid, sealed environments can permit bacterial biofilm formation on the cup surface. This is a use-maintenance issue, not a material defect; regular boiling and air-dry storage eliminate this risk.
Allergic reaction to silicone or additives
Silicone allergies are rare but documented in medical literature, typically affecting individuals with prior silicone implant exposure. AllMatters does not disclose vulcanization catalysts or colorant pigments; nickel or cobalt in dyes could theoretically trigger contact dermatitis in sensitive users.
Heat-induced degradation or off-gassing
Medical-grade silicone is thermally stable to 200°C; boiling (100°C) poses no degradation or volatile organic compound release risk. No odor or chemical fume hazards are documented for AllMatters cups at normal use temperatures.
PFAS in surface coatings or processing aids
Brand does not disclose whether PFAS-based mold release agents or Teflon-family coating coatings were used during manufacture. Silicone products can contain legacy PFAS at trace levels; AllMatters' silence on this supply-chain detail is unresolved.
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.
