Description
The Xiaomi Smart Air Purifier 4 is engineered to improve indoor air quality for allergy sufferers and households with pets. Its core technology is a 3-in-1 filtration system (primary filter, high-efficiency filter, and activated carbon) that effectively traps pollutants, harmful gases like VOCs, and odors.
Compared to conventional HEPA filters, the purifier’s high-efficiency media is less dense, allowing more airflow to pass through at higher speeds while maintaining the same cleaning efficiency, resulting in lower noise levels and energy consumption. The unit also uses negative air ionization to keep the atmosphere fresh by neutralizing suspended pollutants.
