The Xiaomi Air Purifier HEPA Filter is designed to eliminate up to 99.97% of particles as small as 0.3 microns from the air. This true HEPA filter is designed for airborne dust, cigarette smoke, pet dander, mould spores, pollen, germs, virus, and odours.

When this is combined with a 3 stage filtration system, the pre-filter, HEPA filter, and the carbon activated work together to capture particles and odours in the air. Its tower-shaped cylinder design helps circulate the air more effectively. The Air Purifier HEPA filter helps to purify the air while having a 3 to 6-month life span.
