Verdict

The Xiaomi Smart Air Purifier 4 Compact (XM200071) is a compact, lightweight 2.2 kg desktop or floor-standing device designed for small spaces between 16 to 27 m², featuring a clean air delivery rate (CADR) of 230 m³/h and a low maximum power consumption of 27 W. Key advantages include an energy-efficient brushless DC motor that limits sleep mode noise to just 20 dB, TÜV Rheinland Allergy Care certified 3-in-1 filtration trapping 99.97% of 0.3-micron particles, and robust smart integration via the Mi Home app, Google Assistant, and Amazon Alexa. However, it lacks a precise real-time numerical PM2.5 display on the unit, lacks enough activated carbon for heavy volatile organic compounds (VOCs) or strong odours, and requires the mobile application to adjust specific manual fan speeds due to minimal on-device physical buttons.
