2-in-1 design: The newest Q10 combines a dehumidifier and air purifier in one unit. The purifier can operate alone or together with dehumidification, and you can select the mode easily with touch controls. Space-saving and cost-effective. Powerful air purification: The filtration system traps 99.97% of particles as small as 0.1 microns and large pollutants such as dust, pet dander, and smoke. This helps create fresher air in your room. High-efficiency dehumidifier: The unit has a 35 oz water tank and can remove up to 25 oz of moisture per day in an ideal environment of 86F and 80% RH. It covers about 2000 cubic feet (215 sq ft) and reduces humidity to make living spaces more comfortable, helping prevent dampness and mustiness in hot or humid seasons. Efficient filter: Original high-efficiency filter replacement for the Q10 air purifier, featuring a 3-layer filtration system. Compatible with models B08BBYPZQJ and B08M3SZQHV.
