Kbs-813-bf main feature: • Kingby™ peci Patened photoelectrocatalaysis ioner with highly –efficient 4-step purifications : 1) high voltage electric field itself kills micro-organisms directly, 2) special ion precipitator removes dust efficiently 3) active hydroxyl is diffused into the air abundantly in the photocatalyst oxidation reaction activated by the photoelectrocatalaysis field ; 4)the the peroxide , superoxidized ions and ozone generated in the photoelectrocatalaysis reaction still exist after leaving the catalaysis device , and can sterilize and purify the air. • Photocatalysis net uv lamp Combines with uv lamb to generate hydroxyl(oh), neutralize and decompose toxic chemical.Like volatile organic compounds (vocs) , and by killing bacteria and mildew. It's self cleaning ability keeps the purification on, and is also safe and stable • Anion generator Negative ions can actively kill bacterial and mildew in air and even in the furniture corners removes airborne pollutants from the air .They make the air inside your house clean and health. • 4 stage air flow control Design to adjust to multiple level of cleaning based on need • Wide-angled remote control Smart remote lets you easily manage your settings across the rooms, make you superior comfort • Intelligent indicator Reminds you at appropriate time for filter change, avoid second air pollution . • Sleeping mode Enables comfortable sleep environment • Timing mode You can operate the device for a set number of hours (1/2/4/8) • Child lock Prevents unwanted operation of the device and/or change of settings
