What makes 4C Air masks better than other masks?

Instead of a mix of melt-blow materials commonly used in most hybrid masks today our particle mask uses a patented nano media material that provides amazing filtration compared to other masks.  Our nano masks average up to 99% efficiency and are GB2626-2019 certified (NIOSH N95 equivalent filtration).

In filtration and breathability tests, our AireTrust masks performed significantly better than competitive brands. Our masks only weigh 1/3 of an ounce and fit snugly against the face using ear loop straps.

Ideal for filtering out harmful airborne contaminants at the PM2.5 level.
