Designed specifically for the HEPA 700, these pre-filters and HEPA primary filter ensure the highest air filtration efficiency. The unit's primary HEPA filter media removes 99.999% of .1- .5 micron dust, mold and other potentially harmful particulates to pass stringent DOP air filtration tests required for some projects. The optional activated carbon filter with a 1-inch pre-filter and HEPA filter will remove odors, fumes and smoke - especially helpful in wildfire-prone areas.
