Af main feature •Multi-layered Powerful 6 stage patented advanced multi-layered purification process eliminate respiratory airborne particles & dreaded airborne infections, making the air 99.9% pure & healthy •Pre filter Filters out large particles such as dust, dirt and pet dander •Honeycomb active carbon filter This highly porous filter gives the carbon a large surface area to chemically bind and absorb more impurities like volatile organic compounds (vocs) and other noxious gases •Hepa filter Can remove airborne pollutants down to 0.3 microns in size with an efficiency of 99.9%. The significance is that the hepa filter operates on the nanoscale, dealing with ultrafine particles which other purifiers cannot remove. It eliminates bacteria, pollen, and combustion particles from automobiles and smoke through a nano-fibre structure •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, advoid 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
