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.
