Product details
The Xiaomi Smart Air Purifier 4 Lite combines household air filtration with a front LED display and connected controls. This listing is the EU version supplied in the price list. Its white body measures 240 × 240 × 533.5mm and weighs approximately 4.8kg, giving you clear dimensions to check against the intended position in your room before installation.
Xiaomi specifies a particle clean air delivery rate of 360m³/h under its stated test conditions. The published effective coverage area is 25–43m². These figures describe the manufacturer’s testing and calculation method. Room shape, airflow, doors, pollution sources and the selected operating mode all affect practical performance. Keep the purifier’s air path clear and choose a location suited to the room layout.
The filtration system combines a primary filter, Xiaomi’s high-efficiency filter material and activated carbon. The stages collect larger debris, smaller airborne particles and certain odours as air passes through the appliance. The filter is a replaceable part, so follow the purifier’s reminders and maintenance instructions rather than assuming the same replacement interval suits every environment. The compact footprint makes the Lite convenient for a bedroom, kitchen or study.
Sensors include pm2.5 laser sensor; temperature and humidity. The front display makes operating information available without opening the phone app. Xiaomi Home or Mi Home app support provides remote control and operating settings after the purifier is added to a compatible network. App and voice-control features depend on successful setup, the relevant services and compatible devices; smart speakers are purchased separately.
The stated Night Mode noise level is 33.4dB(A), while the specification page lists a maximum noise rating of ≤61dB(A). Those figures refer to different operating conditions. Choose an appropriate mode for the time of day and remember that sound in a room also depends on placement and surrounding noise. Published power consumption is 33W at maximum filtration.
The package contains air purifier ×1; filter ×1; power adapter ×1; user manual ×1. Follow the supplied manual for setup, connection and filter replacement. Check the filter compartment before starting the appliance, retain the regional power accessory, and review the display or app when changing settings. The purifier supports everyday household air cleaning; its performance measurements describe tested conditions rather than a guaranteed result in every room.
