Description
The Xiaomi Smart Air Purifier 4 Compact is a small-format air purifier designed to improve indoor air quality in bedrooms, home offices and other compact spaces. It combines a space-saving footprint with a multi-stage filtration system and smart connectivity features to support cleaner, more comfortable environments.
The purifier uses a high-efficiency 3-in-1 filter that captures up to 99.97% of particles as small as 0.3 microns, including dust, pollen, smoke, pet dander and other common airborne pollutants. A 360-degree air intake and a particle clean air delivery rate of 230 m³/h enable effective circulation in rooms within its recommended coverage range. Integrated sensors monitor particulate levels in real time and automatically adjust fan speed to maintain consistent purification performance while optimizing energy use.
Smart functionality is provided through compatibility with the Mi Home/Xiaomi Home app, allowing remote control of operating modes, scheduling and air quality monitoring. The purifier also supports voice control via popular smart assistants when used with compatible devices. Operating modes such as Auto and Sleep are designed to balance performance and noise, with sound levels as low as 20 dB in sleep mode and overall power consumption of just 27 W, making it suitable for continuous operation.
In everyday use, the compact design allows the unit to be placed on the floor, on a desk or on a side table without occupying much space. It is suited to allergy-sensitive households, homes with pets and urban apartments where fine dust and odors are a concern. Filter replacement is designed as a simple one-step process, and the system provides reminders when a new filter is required, helping to maintain consistent air quality over time.
With its combination of efficient filtration, quiet operation and smart control options, this compact air purifier offers a practical solution for maintaining cleaner air in small to medium rooms while integrating smoothly into modern connected home setups.
