Thanks to a nano-filtration process, an internal 'closed cell' layer guarantees a high filtering efficiency without compromising breathability.

The internal part of U-Mask Model 2.2, the refill filter, is composed of layers of hypoallergenic and nano-filtering non-woven fabric and the exclusive Bio-Layer. Together with the cover, U-Mask has 5 layers of filtration. It is reusable and acts against pathogens up to a maximum of 200 hours of respiratory use.

The fabrics that make up the refill filter are subjected to an electrostatic charge process.

The Bio-Layer™ is composed of an active ingredient capable of self-sanitising the mask and preventing bacterial proliferation.

U-Mask technology aims to maximise bacterial filtration efficiency (BFE) in both directions, from the inside to the outside and vice versa.
Each production batch is tested.

The outer part of U-Mask Model 2.2, the cover, is soft, elastic and washable. Made from 100% regenerated nylon, it is splash-resistant and designed to maximise comfort. 

A nose clip ensures a perfect fit of the mask to the face, preventing it from sliding down.
