PM 2.5 Filters have proven to be extremely effective in blocking out hazardous nanoparticles. These 5 layered filters can be coupled with any cotton mask to block virus particles. The composition of this filter is exactly like the popular N95 and KN95 respirators.
There are two layers of Melt-blown Fabric, an advanced material with electrostatic properties responsible for filtering microscopic particles. There is one layer of Activated Charcoal which has antibacterial properties and traps particles through absorption. Finally, these layers are kept in place with 2 layers of Spun-bond Fabric which filters out larger particles and provides support to this filter.
These filters retain their properties for up to a year and lab tests have shown that a mask with a PM 2.5 filter can filter up to 90% of airborne particles.
Comes in a pack of 5 and can be used to replace pre-loaded filters in Polygiene® ViralOff® 4-Layer Reusable Masks.
