The Minuteman Bio-Haz Vacuum is specifically built to use a U.L.P.A. (Ultra Low Particulate Air) Filter for the remediation of hazardous mold by use of a five-filter media. This filtration is designed to remove stachybotrys colonies, aspergillus spores, and penicillium spores with the U.L.P.A filter to remove 99.999% of the partials down to 0.15 microns. This Bio-Haz vacuum is also ideally suited for the removal and containment of “anthrax” dust and viral particulate collection. The Bio-Haz Vac is made to be used for dry-only pick up (particulate matter only - not vapor!). This package includes filters, complete pre-filter package, and 1-1/2” tool kit. Minuteman also offers a which is more affordable but only filters down to 99.95% down to 0.3 microns and should mainly be used for mold and dust, so please chose correctly.
