With ViralOff®

Eco-Friendly Function

The NanoFit Mask is infused with ViralOff® by Polygiene, an antimicrobial treatment that protects the mask and allows it to be reusable without needing to be washed – saving time and energy while decreasing your environmental footprint.

ViralOff® is made with recycled silver. Its main ingredient is registered with the EPA and has no effect on the skin as it doesn’t interfere with the skin’s natural bio-flora.

Redefine Design

The NanoFit Mask’s sleek design is optimized for comfort, fit, breathability, and long-term wearability.

A correct, snug fit ensures particles cannot leak through gaps between the mask and your face.

The adjustable nosepiece is cushioned inside a soft fabric blend, designed to form specifically to the face. Your exhale is directed down rather than up, so it doesn’t fog glasses.

The NanoFit Mask is available in five sizes, including two kid’s sizes, to provide an optimized fit.

Nanofiber Filtration Technology

The NanoFit Mask’s four-layer replaceable filter is equipped with nanofiber filtration technology and effectively filters particles as small as 0.3 μm (microns).


Nanofiber technology provides superior filtration because, unlike traditional filters, it does not depend on static electricity to be effective. Therefore, it maintains its effectiveness in humid and wet conditions, such as rain, sweat, spit, and condensation produced from breathing.


Unlike melt-blown filters and masks, our nanofiber filters are electrospun, so they have a consistent diameter for superior breathing comfort.
