KN95 DISPOSABLE FACE MASK (SEALED BAG OF 5 MASKS)
KN95 offers the best protection against Corona and other viruses. It incorporates "melt blown" technology which excludes viruses and microbes. Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery systems. The substantial benefits of melt blowing are simplicity, high specific productivity and solvent-free operation. Choosing an appropriate combination of polymers with optimized rheological and surface properties, scientists have been able to produce melt-blown fibers with an average diameter as small as 36 nm.
These are disposible masks and should not be used more than one day of intensive use, or 2-5 days or casual of intermittant use. If the mask becomes wet, discard it properly.
