The Winix 5500-2 Air Cleaner replaces the wildly popular 5500 model. It is designed for any home environment and ready to capture dust, pollen, pet dander, smoke, mold spores, volatile organic compounds, and household odors. This unit is best used for medium to large living spaces, kitchens, or bedrooms. The WINIX 5500-2 uses a 3-Stage Air Cleaning System, featuring a Washable AOCTM Carbon Filter, 99. 97% True HEPA Filter, and Winix PlasmaWave Technology.
We still prefer the AP-1512HH for its lower energy consumption, smaller visual footprint, and manual display-shutoff feature—the Winix’s display shuts off only when it’s on its lowest fan speed, so if you want a dark bedroom, you have to give up a lot of air filtration—but it’s a close race.The Winix 5500-2 is an exceptional performer on particulates, capturing 99.9% of the smoke in our test room in just 30 minutes on high.
