Could loose edges of an insert contact the lips or nostrils?

Could loose edges of an insert contact the lips or nostrils?

The company publishes no finished-mask evidence, and it offers no respirator, mask or insert.

The Terms of Use state that, as of their effective date, the Water, Textiles, Food packaging, and Medical devices chapters describe Research Applications, and that they do not describe finished products currently available from C-POLAR for those uses. What the Textiles chapter publishes is the material: the NanoFlashing™ Textile has a permanent positive polarity, a fixed positive charge, and the fabric stays waterproof, breathable, strong and washable. Where an edge sits against a face is a property of a finished mask, and it is assessed by whoever designs and sells that mask. What the company states about skin contact is a certification and a laboratory study of the material: NanoFlashing™ is certified to OEKO-TEX® Standard 100, Product Class II, the class for products in direct contact with skin, under OEKO-TEX Service GmbH, Certificate 17.0.25812, and Product Safety Labs, Study 65324, completed 31 January 2024, reported that the material it tested “is not considered to be a contact sensitizer”. A copy may be made available on our review of the request.

The Terms of Use state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it.” Certificate 17.0.25812 can be checked at source in OEKO-TEX’s public label check.
