- Primary HEPA 700 Filter (for both HEPA 700 and AP 700)
- 2-in. MERV 8 Pre-Filter (for HEPA 700 only)
- 1-in. MERV 8 Pre-Filter (for both HEPA 700 and AP 700)
- 1-in. Activated Carbon Filter (for both HEPA 700 and AP 700; if using with HEPA 700, insert closest to inlet, then add 1-in. Pre-filter)
Working together, HEPA 700 pre-filters and true HEPA filter ensure the highest air filtration efficiency.
The unit's primary HEPA filter media removes 99.99% of .1- .5 micron dust, mold and other potentially harmful particulates to pass stringent DOP air filtration tests required for some projects.
The optional HEPA 700 activated carbon or charcoal filter with a 1-inch pre-filter and HEPA filter will remove odors, fumes and smoke - especially helpful in wildfire-prone areas. Each filter's 2.5 pounds of carbon pellets provide more than 1 million square yards of surface to adsorb noxious odors - that's twice that of many other carbon filters.
