Xiaomi Smart Air Purifier 4 Compact

The Xiaomi Smart Air Purifier 4 Compact (AC-M18-SC) is a space-saving, high-efficiency air treatment solution designed for small to medium-sized rooms. Despite its small footprint, it uses an advanced 3-in-1 filtration system to trap 99.97% of particles as small as 0.3 microns, effectively removing pollen, dust, smoke, and pet odors. Its low energy consumption and quiet operation make it ideal for bedrooms and home offices.

Key Features

• High-Efficiency Purification: Features a Particle CADR (Clean Air Delivery Rate) of 230m³/h, capable of purifying a 16–27m² room effectively.
• Whisper-Quiet Sleep Mode: In Sleep Mode, the noise level drops to as low as 20dB, making it quieter than a library. The display light can also be turned off for undisturbed sleep.
• Low Energy Consumption: At maximum output, the power consumption is only 27W. Running the device for 24 hours consumes just 0.7kWh.
• Smart App & Voice Control: Fully compatible with the Mi Home/Xiaomi Home app, allowing for remote scheduling and real-time air quality monitoring. It also supports Google Assistant and Alexa for hands-free voice control.
• Real-Time Air Quality Indicator: Uses an infrared laser particle sensor to track air quality changes, displayed via a four-color indicator light (Green, Yellow, Orange, Red).
