Dustless Technologies Backpack Vacuum
Dustless Technologies HEPA Backpack Vacuum - CommercialVacuum.comWhile most vacuums exhaust dust back into the air, the HEPA Back Pack vacuum will not. Using a clamp down, sealed top and three step HEPA filtration system, the vacuum captures 99.97% of particles at 0.3 microns. That is 0.00003 centimeters across, much smaller than the width of a human hair, a red blood cell, and nearly all viruses, bacteria, pollen, and allergens.
