The 698 Square Foot Air Quality Sensing Purifier

This is the air purifier that monitors air quality and automatically adjusts its cleaning settings in response to pollutant levels. Integrated particle and gas sensors monitor air impurity levels and automatically increase the speed of the fan to remove dust, pollen, viruses, and bacteria. Its three-stage filter system uses mechanical and electrostatic filtration to eliminate 99.97% of particles as minute as 0.1 microns, including mold spores and pet dander. The air purifier has the highest possible clean air delivery rate for tobacco smoke (450), dust (400), and pollen (450) and cleans the air in a 698' sq. room five times in an hour. On high, the air purifier generates only 66 decibels—barely above normal conversation volume—and users can also manually select one of three cleaning speeds. An LCD shows pollutant levels, fan speed, and remaining filter life, and four casters enable easy relocation. Includes remote control and one filter (additional filters sold below). 26” H x 20” W x 13” D (35 lbs.)
