General Information

AIR488 addresses indoor air pollution. 5-in-1 filter can effectively clean indoor air. Aluminum alloy filters, primary filters, activated carbon filters, antibacterial cotton filters and HEPA filters are the keys to achieving a pollution-free home. Functions such as automatic mode, sleep mode, negative ion, UV lamp disinfection and parental control can be set at any time through a simple control panel or remote control. The upward-flowing air travels along the ceiling and walls and is drawn back by the air purifier, creating a powerful airflow that allows hidden dust in the room to be filtered. Multiple filtration can quickly clean indoor air. Another feature is the smart sensor system that automatically detects the air quality and indicates it on the control panel as a PM2.5 reading. In automatic mode, the air purifier adjusts the clean air output according to the air quality.
