HEPA air scrubber or negative air pressure machine
First Claim
1. A conversion kit for converting an air mover including an exhaust vent into an air filtration system having a high efficiency particulate air filtration capacity, said kit comprising:
- a) a high efficiency particulate air filtration unit comprising an open end of a size to cover the exhaust vent; and
b) a fastener for attaching the open end of the high efficiency particulate air filtration unit to the exhaust vent, wherein the fastener forms an airtight seal between the exhaust vent of the air mover and the high efficiency particulate air filtration unit.

Abstract
The invention converts an air mover into an inexpensive, lightweight, portable high efficiency particulate air (HEPA) filtration system. The air filtration system is preferably used either for light-duty or heavy-duty air filtration. Light-duty operation involves strapping a HEPA filtration bag over the exhaust vent of the air mover. Heavy-duty operation involves attachment of a HEPA filter encased in a hard metal or plastic shell to the exhaust vent of the air mover by a flexible sleeve. A conversion kit for converting an air mover to a HEPA filtration system and a method of converting an air mover to a HEPA filtration system are also disclosed.
