The Xiaomi Smart Air Purifier 4 Compact is a compact air purifier designed to provide clean, fresh air in any room. Thanks to its high-efficiency filter and three-stage filtration system, the device removes dust, pollen, smoke, pet dander, and other pollutants. It is suitable for rooms ranging from 16 to 27 m² and is ideal for people with allergies and families with pets.
The filter uses PP fibers with melt-blown electrostatic technology, which allows for more space between the fibers and greater airflow. The system captures up to 99.97% of particles as small as 0.3 microns. The purifier is equipped with a particulate sensor that monitors air quality in real time and displays the data via an OLED display and a four-color indicator.
The device features a dual-purpose design—it can be placed on a desk or on the floor. Its compact size and convenient portability make it easy to integrate into any space. The motor is brushless, ensuring quiet and energy-efficient operation.
The purifier supports smart control via a mobile app, as well as Google Assistant and Amazon Alexa voice assistants, allowing for remote control and speed adjustment. In manual mode, a specific cleaning zone and speed can be set according to the user’s preferences.
The three-stage filtration system effectively removes dust, smoke, ash, pet hair, and odors, as well as filtering allergens such as pollen, dust mites, and dander. This provides optimal protection for families with pets and people with allergies.
The purifier operates quietly in background mode, improving air quality without disrupting work or sleep. Its elegant design with a matte finish and clean lines makes it suitable for any interior.
