Introducing a genuine HEPA vacuum that can be worn comfortably as a backpack. The HEPAPro 10EB offers 10-quart recovery capacity and the ultimate in HEPA filtration and clean-air technology. Don’t be misguided by competitive backpack vacuums claiming to have HEPA filtration. This backpack is a genuine “HEPA Vacuum” so it has a HEPA filter that is individually tested and certified at a minimum efficiency of 99.97% at .3 microns. It is the only backpack vacuum equipped with three (3) HEPA filters. The main HEPA filter, secondary cloth pre-filter and disposable paper filter bag are all drop-in, modular components on the intake side of the motor. This is your “fail-safe” guarantee to prevent any accidental bypass of dangerous dust that may escape from the vacuum and contaminate the air. Two smaller HEPA filters are mounted at the motor’s output to ensure absolute clean-air exhaust. The model HEPAPro 10EB is approved for EPA RRP regulations for removal of lead based paint particles. It also meets OSHA requirements for reducing permissible levels of crystalline silica on construction and restoration jobsites. It is also ideal for advanced cleaning in schools, hospitals and other public areas.
