Your Personal Shield Against Pollen & Fine Dust
The Xiaomi Smart Air Purifier 4 Compact is more than just a technical device – it's your partner for a healthier home. For allergy sufferers, in particular, pure air is crucial. The highly efficient 3-in-1 filter system works tirelessly to remove 99.97% of all particles down to 0.3 micrometers from your indoor air. This means: Less pollen, less house dust, less pet dander, and noticeable relief for your respiratory system. The pre-filter takes care of coarse particles, while the Xiaomi High Efficiency Filter reliably captures even fine dust (PM2.5) and other allergens.
Intelligent Air Purification That Adapts to Your Life
Why should you constantly worry about air quality when your air purifier can do it for you? In automatic mode, the integrated PM2.5 sensor continuously monitors the air and automatically adjusts the cleaning performance. As soon as air quality drops, the device increases fan speed and returns to a quiet, energy-saving mode when the air is clean. This way, you always enjoy optimal air conditions without lifting a finger.
Compact Powerhouse: Big Performance in a Small Space
Don't let its size fool you. With a diameter of only 22 cm and a height of 35.5 cm, the Air Purifier 4 Compact finds a place everywhere – whether on the desk in the office, the chest of drawers in the living room, or the bedside table in the bedroom. Despite its compact design, it delivers an impressive Clean Air Delivery Rate (CADR) of 230 m³/h, making it perfect for rooms from 16 to 27 m². It is a prime example of modern `Smart Living & Gadgets`.
Full Control: Smart Home Integration with App and Voice
Simply connect the air purifier to your 2.4 GHz `Network` and discover the full range of functions via the Mi Home App. Create individual schedules, manually adjust the fan speed in 14 steps, activate child lock, or check the remaining filter life. For maximum convenience, the smart air purifier with Google Home control can be connected to Google Assistant and Amazon Alexa. A simple voice command like 'Hey Google, turn on the air purifier' is enough, and the device immediately provides fresh air.

Frequently Asked Questions (FAQ)
How often does the filter of the Xiaomi Air Purifier 4 Compact need to be changed?
The filter should be replaced every 6 to 12 months. The exact lifespan depends on the intensity of use and air pollution. The Mi Home App monitors the filter status and sends a notification when a change is required.
Can the Xiaomi Air Purifier 4 Compact be connected to a 5 GHz WiFi Network?
No, the device exclusively supports 2.4 GHz WiFi networks with WPA or WPA2 encryption. Connection to a 5 GHz Network is not possible.
Does the device display exact PM2.5 values?
No, due to the built-in infrared sensor, the device and the app only display air quality via a four-color scale (from 'Good' to 'Heavily polluted'), not as an exact numerical PM2.5 value in µg/m³.
Is the Xiaomi Air Purifier 4 Compact loud during operation?
In sleep mode, the device is extremely quiet at approx. 20 dB(A) and barely audible. At the highest setting, the volume can increase up to 60 dB(A), which is clearly audible. For daily use in quiet environments, the medium settings are ideal.
Which pollutants can the air purifier filter from the air?
It effectively filters fine dust (PM2.5), pollen, pet hair and dander, dust mites, smoke particles, and other allergens up to a size of 0.3 micrometers from the air. The activated carbon layer also helps to reduce light odors.
Do I need the app to use the air purifier?
No, the basic functions (On/Off, switching between automatic, sleep, and preset manual modes) can be controlled directly on the device. However, for the full range of functions, such as creating schedules or precisely adjusting the fan speed, the Mi Home App is absolutely essential.
