Lunette Menstrual Cup, Reusable, Model 2, Violet
Lower concern, medical-grade silicone is inherently PFAS-free, but brand offers no explicit PFAS commitment.
Lunette menstrual cups are made from medical-grade silicone, a material that does not require PFAS-based coatings or treatments. No public disclosure of PFAS testing or PFAS-free claims exists from the brand, but silicone itself is not a typical PFAS-containing material. This is a reusable product with minimal chemical exposure risk.

The full breakdown
What it's made of and why it matters
Lunette Model 2 is constructed from medical-grade silicone, a synthetic polymer engineered for biocompatibility and intended for prolonged internal contact. Medical-grade silicone does not contain BPA, phthalates, or PVC; it is non-porous, resists bacterial colonization, and does not leach estrogenic compounds under normal body temperature or menstrual fluid pH. The material is inherently PFAS-free because fluorine-containing water repellents are not required in its formulation.
The brand's record and disclosure
Lunette provides minimal public toxicology documentation; no third-party certifications (ISO 10993 biocompatibility, FDA 510(k), or equivalent) are visibly claimed on product labeling or website. The brand does not explicitly address PFAS, heavy metals, or long-term safety data, which represents a communication gap rather than a confirmed safety failure. No product recalls or toxicity complaints appear in consumer safety databases, and the cup has been marketed since the early 2000s without reported adverse events.
How it compares in its category
Menstrual cups as a category are safer than single-use alternatives (tampons, pads) because they eliminate repeated contact with bleach residues, dioxins, and synthetic fibers. Compared to competitors (DivaCup, Saalt, Flex), Lunette's medical-grade silicone is chemically equivalent; differentiation lies in brand transparency and design ergonomics, not material safety. Lunette's opaque communication stance is typical of older-entry brands that predate current consumer disclosure expectations but is less robust than newer competitors offering ISO/FDA documentation.
If you buy it
Rinse thoroughly under cold water after each cycle and boil in water for 5-10 minutes monthly to sterilize; do not use soap with antibacterial agents, as they may degrade silicone over decades of use. Medical-grade silicone is stable up to 180 Celsius (well above body temperature) and does not off-gas or leach under normal use. Replace the cup if walls become sticky, opaque, or visibly cracked; degradation typically occurs after 5-10 years of regular use. Store dry in the provided pouch to prevent dust accumulation and odor absorption.
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 long-term leaching
Medical-grade silicone is stable under body temperature but can degrade if exposed to extreme heat, harsh soaps, or prolonged sun exposure. No published data confirms leaching of silicone polymers or oligomers into menstrual fluid at body pH, but long-term safety data beyond 10 years of use is not publicly available.
Bacterial biofilm or odor colonization
Silicone's non-porous surface resists bacterial adhesion; Lunette provides no evidence of increased infection rates. Poor cleaning (if instructions are not followed) can trap menstrual fluid residue, but this is a usage failure, not a material defect.
Heavy metals in pigments (violet dye)
The violet colorant in Model 2 is not disclosed by the brand. Medical-grade silicone formulations typically use FDA-approved synthetic iron oxides or organic pigments, but Lunette does not publish pigment specifications or testing data for cadmium, lead, or chromium.
Allergic sensitization or contact dermatitis
Silicone is a non-allergenic material in clinical use; no adverse event reports for Lunette cups appear in medical or consumer databases. Individual sensitivity to undisclosed colorants is theoretically possible but statistically rare.
Phthalate or BPA contamination (from manufacturing)
Medical-grade silicone formulations do not contain phthalates or BPA by design. Lunette does not claim third-party verification of manufacturing purity, so cross-contamination during production cannot be ruled out but is extremely unlikely given the mature manufacturing standard for medical silicone.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
