This is the patented filterless purifier that employs technology developed by NASA for use aboard space shuttles to scrub and sanitize the air. Rather than trying to catch airborne particles like a net, this unique purifier destroys them on a molecular level. A quiet fan draws air into the sleek box, where the unit’s reaction chamber bombards the pathogens with UV light and chemical processes, eliminating contaminants such as pet dander, mold spores, and more than 99.99% of volatile organic compounds (VOCs). The purifier emits no harmful ozone while it runs and cleanses the air in any size room. Its three settings include an automatic mode that drops the speed and volume when it detects that a room has been darkened to aid sleep. With a minimalistic design that blends with home décor. The reaction chamber lasts up to one year. Plugs into AC and uses as little power as a 60-watt lightbulb. 18 3/4" H x 7" W x 6" D. (9 lbs.)
