The Winix HR900 is the ultimate air purifier for pet owners! It offers five-stage filtration with a true HEPA filter and is AHAM verified at 300 sq ft but can filter 1450 sq ft in 1 hour. The first line of defense in this purifier is the Ultimate Pet Pre-Filter which filters out pet hair, dander, and visible particles. This filter is easy to change and will keep your filter running at maximum efficiency! Next, your air passes through a washable pre-filter that captures the largest airborne molecules. Next up, the washable AOC carbon filter reduces odors and captures airborne VOCs. After that, the True HEPA filter filters out the finest molecules, such as dust, smoke, and remaining pet dander. Finally, PlasmaWave technology removes the rest of the airborne particulates by creating charged ions to latch onto the contaminants. Triple smart sensors plus an auto mode keep your filtration running at the optimal speed throughout the day and a sleep mode keeps it quiet during the night. Energy Star certification means you can always prioritize your air quality without worrying about your electric bill
