The XPOWER Air Scrubber with 4-Stage HEPA Filtration is a commercial-grade air filtration system with 4 stages of filtration to promote a healthy environment cleansed of harmful airborne contaminants such as hair, dander, pet allergens, mold, and bacteria. The 2 outermost nylon mesh filters capture 90% of medium to large contaminants such as hair and can easily be removed and hand washed. The 3rd stage of filtration is composed of activated carbon which effectively absorbs and neutralizes a wide range of odors and other pollutants. The final stage of filtration is a 1.4 inch. thick HEPA filter which filters out 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 HEPA filter needs replacement. Running at an energy efficient 2.8 amp draw, the cost-effective X-3580 features a powerful high-torque 1/2 HP motor that can sanitize the air in rooms up to 1500 sq. ft. With a 5-speed control, you have the flexibility to run the unit on a quiet low speed during working hours and then ramp up the speed to run the purifier overnight. Everyone will benefit from an odor free environment that is also free of harmful pollutants that can contribute to and aggravate conditions such as asthma, cardiovascular disease, and other respiratory diseases. Link your XPOWER X-3580 air purifier with the XD-125 other model of XPOWER dehumidifier (not included) for optimum performance, reduced humidity, and decreasing drying times by up to 30%.
