Pre-Owned 〞 You may not know this, but indoor air is more polluted than outdoor air because pollutants build up more in contained areas than open spaces do. That is why cleaning the air inside your home or office is necessary to avoid allergies and other airborne diseases. The hOmeLabs HEPA Air Purifier’s 3-stage purifying technology has a pre-filter, HEPA and activated carbon filter that removes 99.97% of microscopic particles as small as 0.3 microns in size effective in capturing dust, soot, pet dander and eliminates odor from smoke, fumes or cooking smells. It’s small so you can place it anywhere without taking up too much space and it doubles as a night light by placing it in your bedside table. It also comes with a child lock feature, no disturbing noise and a customizable air circulating speed setting. All these technologies rolled into one compact device to help you breathe cleaner air.
