Editor's Pick: If you have cats or dogs at home, the floating fur and dander in the air are hard to see with the naked eye. This machine captures particles as small as 0.01 microns, filtering out pollen, smoke odors, and pet dander. The air quality indicator changes color in real time, and it automatically switches to sleep mode after lights are turned off at night. It runs quieter than a refrigerator, so it won't affect your sleep when placed in the bedroom. The outermost layer of the filter is washable, making routine maintenance much easier.
