Not even a virus gets through HEPA
Only Wisfresh HEPA filtration technology traps ultrafine particles down to 0.003 microns - 10x smaller than a virus! Independent testing verifies that IQAir HyperHEPA filtration traps at least 99.5% of all particles down to 0.003 microns for filtration against fine and ultrafine particles, including bacteria and viruses.
This is why critical environments trust wisfresh
Ultrafine particles are smaller than 0.1 microns in diameter and comprise about 90% of all airborne particles. The tiny size enables them to be easily inhaled, deposited into the lungs and absorbed directly into the bloodstream. From there, they travel to all vital organs, including the brain. Viruses, smoke and diesel soot are all ultrafine particles.
Wisfresh HEPA filtration is proven and certified to filter at least 99.5% of all particles down to 0.003 microns - which is 100 times smaller than 0,3 microns.
