The Xiaomi Smart 4 Lite Air Purifier offers you peace of mind and all-day protection for those who suffer from rhinitis and allergies. The air purifier protects your respiratory health by keeping the air in your home clean and safe to breathe. It does this thanks to a three-in-one filtration system that can remove up to 99.97% of 0.3m particles. In addition to your high-efficiency filter system, your purifier also releases negative ions to keep the air fresh, helping you stay refreshed after a hard day's work.

Xiaomi combines two filter technologies to give you the best protection. Xiaomis high-efficiency filter media can remove 99.97% of airborne particles of 0.3 micrometres in size and traps dust, PM 2.5, pollen, pet dander, smoke and tiny particles. The activated carbon filter has a high absorption rate and effectively removes common harmful gases such as VOC from your home, as well as eliminating odours to keep your air fresh.

Compared to a conventional HEPA filter, Xiaomis high-efficiency filter allows the air purifier to generate less noise and consume less energy by allowing more airflow to pass through the filter, all the while keeping the same cleaning efficiency. Xiaomi Smart Air Purifier 4 Lite has a particle CADR of up to 360m/h, able to deliver 6000L of purified air per minute, and with 360 all-round air intake, purifying your entire room is effortless. Smart control keeps your home fresh when you're on the move. With support for smart control, ensure that you always return to a home filled with clean, fresh air. Use the Mi Home/Xiaomi Home app from your smartphone to enable purification when away from home. The purifier also works with Hey Google and Alexa for voice control.

It also features a one-touch auto mode, making it even more effective for hands-free purification. Its sensitive, high-precision laser sensors then monitor changes in air quality. Once it determines the air quality in real-time, it then automatically adjusts the purification speeds for automatic purification.

Switch to Night Mode to turn off display luminance for no-glare, no-noise purification. Your purifier will keep air circulating, providing you with the perfect environment for some undisturbed shut-eye. Easy-clean air ducts help clean your purifier from the inside out. Unscrew and remove the grille for easy access to the fan blades and air ducts. This makes for easy cleaning for the inside of your purifier to prevent secondary pollution.
