What makes 4C Air BreSafe 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 offer NIOSH N95 equivalent filtration.
In filtration and breathability tests, our masks performed significantly better than competitive brands.
Ideal for filtering out harmful airborne contaminants at the PM2.5 level.
