är Nano-technology mask filters are developed from the most advanced nanomaterials of today. Their filtration capabilities were tested by a microbiology testing laboratory, which proved their effective protection abilities.
Replaceable mask filters from är - maximum comfort and protectionär Nano Filters for face mask are replaceable and provide extra breathability. They are made of light nonwoven materials with a layer of nanofibers between them, which creates mask filters that are comfortable to wear while providing the highest protection. Pores of nano-technology mask filters from är are so small that they can block tiny particles of common contaminants and pollutants of today. However, their porosity is large enough to remain light and comfortably breathable.
