Xiaomi Smart Air Purifier 4 Compact Filter

This Xiaomi replacement filter is designed for the Smart Air Purifier 4 Compact. It uses three-stage filtration for thorough air purification in your home. The 3-in-1 system tackles dust, pet dander and pollen. The activated carbon layer also absorbs unpleasant odours. The filter's lifespan is between 6 and 12 months.

Three-stage filtration system

The Xiaomi air purifier filter uses a three-stage purification system. The first, primary filter captures large particles such as dust, hair or fine crumbs. This is followed by Xiaomi's high-efficiency filter, which combines electrostatic and mechanical technology. This allows it to tackle pollen, pet dander, smoke and fine PM2.5 dust particles.

High efficiency and odour absorption

The Xiaomi high-efficiency filter operates with 99.97% efficiency in capturing tiny particles as small as 0.3 micrometres. The third and final stage of filtration is an activated carbon layer. This effectively absorbs unpleasant odours.

Long lifespan and easy replacement

This replacement filter is fully compatible with the Xiaomi Smart Air Purifier 4 Compact. The manufacturer recommends replacing it every 6 to 12 months to maintain optimal filtration performance. The total filter lifespan of up to 12 months depends on how often you use the purifier and the level of air pollution in your environment.
