POSITIVE PRESSURE FILTRATION KIT APPARATUS AND METHOD
First Claim
1. A positive pressure filtration kit comprising:
- a filtration unit, the filtration unit being configured and arranged to sealingly fit into an existing opening of an enclosed structure, wherein ordinary course usage of the existing opening is for a purpose other than receiving a filtration unit;
at least one filter in the filtration unit capable of filtering out airborne particulate matter at least as small as 500 microns;
at least one air drawer in the filtration unit to draw air through the existing opening and through the at least one filter, wherein the air is drawn through the filtration unit at a sufficient rate to achieve and sustain a positive pressure environment within the enclosed structure.

Abstract
A positive pressure filtration kit (200) comprises a filtration unit (201), there being at least one filter (202) in the filtration unit and at least one air drawer (204) in the filtration unit. The filtration unit (201) is configured and arranged to sealingly fit into an existing opening of an enclosed structure, wherein ordinary course usage of the existing opening is for a purpose other than receiving a filtration unit. The at least one filter (202) in the filtration unit is capable of filtering out airborne particulate matter at least as small as 500 microns. The at least one air drawer (204) in the filtration unit draws air through the existing opening and through the at least one filter, wherein the air is drawn through the filtration unit at a sufficient rate to achieve and sustain a positive pressure environment within the enclosed structure.
