Good Mask Satisfaction Guarantee. The Good Mask Co. is an industry leader in supplying comfortable KN95 and 4PLY masks in the US. Our face masks are made with natural, high-quality materials and are available in a variety of styles, colors, and designs. Our respirator masks are the highest quality disposable masks on the market.
The KN95 mask is an approved and suitable equivalent of the N95 face mask according to both 3M and the CDC. Importantly, the rounded shape and thicker surface enable our masks to filter fine particles than other masks with rectangular designs, which also tend to be thinner and can only filter particles of roughly 10 microns.
