'KF' stands for 'Korean filter' and the 94 refers to the masks' filtration efficacy. Utilizing a multi-layer filtration system, these Hilipert KF94 Fish Type Masks filter 94% of particles down to 0.3 microns in size, equivalent to the highest filter rating issued by the FDA.
Hilipert's innovative 4-layer active filtration barrier protects respiratory system. It captures great majority of airborne particles while allowing you to breathe easier. Hilipert KF94 Fish Type Masks are effective to filter out pollutants like dust, allergens, pollen, chemicals, and smoke, while other reusable masks are less effective when it comes to filtering harmful particles in the air.
These Breathable Face Masks use three-dimensional protective design with contoured edges, leaving more breathing space for your mouth and nose to breathe. Even the most sensitive skin feels gentle with it.
