The HEPA Back Pack Vacuum is a safe solution for use in homes, hospitals, schools, and jobsites. Complete with a HEPA media filter, the vacuum is safe for lead paint removal, silica dust containment, and general hypoallergenic and janitorial needs. When used with the included HEPA Beater Bar Floor Tool, carpets can be safely cleaned and stripped of pollutants, contaminants, and germs. The enclosed-top, disposable bag is made of HEPA filter material to capture particles down to .3 microns. This one-time-use bag features a peel-and-stick flap to seal the contents quickly and easily. Two more layers of filtration after the disposable bag, a reusable cloth filter and HEPA cartridge filter, catch any excess pollutants. An external agitator rod is used to knock the dust from the filters without opening the unit. The HEPA Back Pack Vacuum was designed to improve worker safety and productivity by allowing the user to move around more quickly and freely. A 5-point harness system seats easily on the user and with the 48.5 ft. included extension cord allow greater portability. The HEPA Back Pack Vacuum features a stainless steel wand that adjusts to 3' with the push of a button for easy access to floors, ceilings and hard-to-reach areas. The wand connects to the hose using an ergonomic pistol- grip handle with suction control.
