Mi Air Purifier

Xiaomi Smart Air Purifier 4 Lite

High-efficiency particle output and rapid purification

Take absolute control of your indoor breathing environment with a continuous stream of pure, dynamic airflow. Engineered for smaller to medium-sized living spaces, bedrooms, or offices, the Xiaomi Smart Air Purifier 4 Lite delivers a robust Clean Air Delivery Rate (CADR) of up to $360text{ m}^3text{/h}$. At maximum operating capacity, its $360^circ$ all-round intake framework can circulate and distribute an impressive 6,000 liters of purified air every single minute, rapidly reducing airborne toxins, seasonal allergens, and microscopic irritants to safeguard your respiratory well-being.

Advanced triple-layer filtration matrix

Breathe clean, clinical-grade air optimized by a high-performance three-in-one filtration layout. The system merges mechanical trapping with an electrostatic charge filter medium to eliminate 99.97% of airborne particles down to 0.3 micrometers in size. The multi-tiered barrier smoothly traps everyday environmental pollutants, including:

• Floating dust, pollen, and cotton fibers

• Drifting pet dander and fine hair strands

• Invisible smoke particles and common H1N1 viruses

Powerful odor and VOC elimination

Keep your household air crisp, pleasant, and completely free of stale odors. Outfitted with an integrated, premium activated carbon filter structure containing 450,000 mg of high-quality carbon material, the absorption performance is 1.8 times higher than standard alternative models. This dense pellet core efficiently breaks down and captures stubborn household odors, cooking fumes, pet smells, and harmful volatile organic compounds (VOCs) like formaldehyde and toluene.

Real-time digital LED air quality dashboard

Monitor your surrounding atmosphere instantly through a beautifully clear visual reporting center. The integrated front-facing LED display provides real-time data on precise indoor $PM_{2.5}$ concentration levels, active room temperature, and relative humidity percentages. A dynamic, color-coded light strip spans the screen to reflect current air health at a quick glance, automatically shifting colors so you know exactly when the room is fully purified.

Smart app integration and voice control automation

Manage your air health seamlessly from anywhere, whether you are relaxing on the couch or heading home from work. With built-in Wi-Fi, the device hooks up securely to the Mi Home/Xiaomi Home smartphone application to unlock full remote activation, operational scheduling, child lock switches, and precise filter lifetime tracking. For automated smart-home environments, it features native compatibility with Google Assistant and Amazon Alexa for hands-free voice control commands.

Whisper-quiet sleep cycles and eco-friendly architecture

Rest completely undisturbed while maintaining a safe, healthy sleep environment. Switching the device into its specialized Night Mode dims the display panel and dials back the fan acoustics to a whisper-quiet 33.4 dB(A). Driven by a highly optimized, low-draw 33W motor engine, the purifier operates with incredible energy efficiency—consuming only 0.8 kWh of electricity over a full 24 hours of non-stop, maximum purification.
