AireTrust Nano Masks – Kids Size Bulk Box – 300 Face Masks


Our bulk box offers 12 boxes (at 25 masks per box) of our kids-sized nano masks. 4C Air has collaborated with AireTrust to create a face mask using our patented BreSafe nanotech for kids that provides your child the safety of filtration similar to a N95 respirator without the heavy restriction to breathing compared to other face masks. Our patented nanotechnology was developed at Stanford University and offers filtration of microscopic airborne particles and super fine PM2.5 hazards. It is paper-thin and fits snugly and comfortably around the face. The kids nano mask comfortably fits most children and is recommended for kids above 3 years of age. We also offer Large and Medium sizes.

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.
