The XPOWER HEPA Mini Air Scrubber with 4-Stage Filter Set is small but powerful. This commercial-grade unit features a 1/2 HP motor which generates up to 550 CFM. The 4 stages of filtration include a carbon filter for effective odor control. The 2 outermost nylon mesh filters capture 90% of medium to large contaminants and can easily be removed and hand washed. The 3rd stage activated carbon filter effectively absorbs and neutralizes a wide range of odors and other pollutants. The final stage HEPA filter removes 99.97% of 0.3-micron sized particulates as well as other particulate sizes including bacteria, allergens, and sub-micron sized dust. A convenient indicator light notifies you when the filters need to be cleaned or replaced. The X-2580’s 5-speed control switch gives you the flexibility to run the unit on a quieter low speed in noise sensitive environments. A lipped air outlet can be easily ducted to channel purified air or create negative air pressure. Stackable and lightweight for easy transport, the rugged X-2580 is ideal for even the toughest water damage restoration and construction jobs.
