N90 Replacement Filters


Regular price $3.99


[5 PACK] The filter inserts are made out of melt-blown, non-woven cloth. The melt-blown process creates very tiny microfibers that filter out particulates from the air. Melt-blown cloth is breathable and is used widely in surgical face masks and medical fabrics. It is also lightweight, flexible, non-burning, non-toxic non-irritating and environmentally friendly.

The filter insert`s effectiveness at filtration decreases with each use. We recommend that each filter insert should be replaced after each use longer than 8 - 10 hours for the best filtration. These filters are not washable and should not be reused.

Additional Features:
1. The diameter of melt-blown fiber can reach 1 ~ 2 microns, which belongs to ultra-fine non-woven fiber rating and +90% filtering efficiency. 2. The cloth features a weight of about 25 grams per square inch. 3. Heat insulation, heat preservation, non-toxic, non-irritating, anti-covid, anti-dust and anti-peeling.
