A true HEPA air purifier best for small rooms! This purifier is AHAM certified for rooms up to 230 square feet. Winix uses a 4-stage filtration system with this purifier. First, a fine mesh pre-filter catches large contaminates and prevents them from clogging the downstream filtration. Then, a true HEPA filter captures 99.97% of airborne allergens down to 0.3 microns in size; this takes care of most dust, smoke, pollen, or pet dander. Then, your air is filtered through an activated carbon filter to reduce odors and capture VOCs. Finally, the air passes through the Winix Plasma Wave filter which creates hydroxyls to generate positive and negative ions to separate hazardous contaminates at a molecular level (without generating ozone!). This filtration method meets the California Air Resource Board's AB2276 standard for ozone emissions with less than 0.05 parts per million. A smart sensor with an auto mode, a sleep mode, an air quality indicator, and a 2-year warranty top off this high-end yet budget-friendly small room purifier.

Small to medium sized spaces that need better air filtration than what a basic air purifier can handle and for people who want elegant simplicity.

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

Rabbit air purifiers are known for their quiet operation, and the BioGS 2.0 is no exception. At only 20dB when set to silent speed mode, the BioGS 2.0 is significantly quieter than other purifiers in its class. The purifier uses four stages of filtration and deodorization, including a pre-filter, activated carbon charcoal filter, proprietary BioGS HEPA filter (a true-HEPA rated filter), and an ionizer to create negative ions and weigh down unwanted air molecules. The BioGS 2.0 is also low maintenance and requires a filter replacement only every 18 months when operating the purifier 24 hours a day. Best for standard filtration of 550 sq ft rooms, or maximum filtration of rooms 275 sq ft or smaller, this is best for users looking for air filtration in medium rooms.. This purifier is also Energy Star certified so you can filter your air 24 hours a day worry-free!
