Available in two finishes， the Hunter HP700 Medium Console Air Purifier will keep the air in your home clean without compromising on style. The console air purifier can clean the air in a 315 sq. ft. space over 60 times each day. After the air enters the air purifier， it passes through an EcoSilver pre-filter where silver nanoparticles prevent the growth of bacteria and viruses. The pre-filter also contains natural coconut carbon which neutralizes harmful VOCs (volatile organic compounds) and household odors from cooking， cleaning， smoking and pets. The air then passes through a True HEPA filter which removes up to 99. 97% of airborne particles as small as 0. 3 microns including smoke， dust， pollen， pet hair and dander， mold spores and dust mite debris. Its recommended to change the HEPA filter every 6-12 months and pre-filter every 3 months， or more often depending on air quality and environmental factors. While it may be compact， its power makes this air purifier ideal for a bedroom， bathroom， kitchen， living room or other large room in your home. The digital control panel makes it easy to control settings. Features 3 fan speeds so you get the cleaning power you want， when you want it. Also features sleep mode with whisper quiet operation for uninterrupted sleep， timer， filter replacement indicator to remind you when its time to change the filters， and optional LED accent light for ambiance or nightlight.
