Cleaner Air. Smarter Control. Better Living.

Bring powerful air purification into your home with the Xiaomi Smart Air Purifier 4 Lite. Designed for rooms from 25 to 43 m², its high-efficiency three-layer filtration captures up to 99.97% of particles as small as 0.3 μm, while activated carbon helps reduce common odors and gases such as VOCs and formaldehyde. With a PM2.5 sensor, LED display, automatic mode and smartphone control, it gives you a smarter way to monitor and purify your indoor air.

Powerful Purification for Everyday Air

With a particle CADR of up to 360 m³/h and 360° air intake, the purifier continuously draws in and cleans air throughout the room. Xiaomi specifies an effective coverage of 25–43 m², making it well suited to bedrooms, living rooms and home offices.

Triple-Layer Filtration That Targets What You Can't See

The integrated high-efficiency filter is designed to capture 99.97% of particles measuring 0.3 μm, including dust, pollen, smoke and pet dander. Its activated-carbon layer also helps absorb odors and common gaseous pollutants such as VOCs and formaldehyde.

Smart Monitoring at a Glance

The built-in laser particle sensor monitors PM2.5 levels, while the LED display provides real-time information about air quality, temperature, humidity and operating status. A color-coded light makes changes in air quality easy to understand without constantly checking your phone.

Control Your Air From Anywhere

Connect the purifier to the Xiaomi Home/Mi Home app to remotely start purification, adjust settings, schedule operation and monitor air quality, even when you're away from home. Compatible voice assistants can also provide hands-free control where supported.

Quiet Enough for the Bedroom

Switch to Night Mode for a quieter environment, with Xiaomi specifying a noise level of just 33.4 dB(A) in this mode. The display can also be turned off, helping minimize distractions while you sleep.
