Xiaomi Mi Smart Air Purifier 4 Lite Filter

The Xiaomi Mi Smart Air Purifier 4 Lite replacement filter keeps the air in your home clean. This three-layer filtration system combines a primary, high-efficiency, and carbon filter into a single unit. It effectively removes up to 99.97% of fine particles, allergens, and unpleasant odours. The filter is designed exclusively for the Xiaomi Smart Air Purifier 4 Lite, and its recommended replacement interval is every 6 to 12 months of use.

Comprehensive three-stage filtration

The filter integrates three stages of air purification. The first, primary layer, serves to capture larger impurities such as dust, hair, or pet fur. This is followed by a high-efficiency filter that deals with smaller particles. The final component is an activated carbon filter, whose task is to absorb gaseous pollutants and odours. The entire system works as a single, replaceable compact unit.

Effective against allergens and dust

The high-efficiency filter removes up to 99.97% of particles as small as just 0.3 micrometres. This value covers a wide spectrum of airborne impurities. The filter thus removes common allergens from the air, including pollen, mould spores, and dust mites.

Fresh, odour-free air

The filter also includes a layer of activated carbon. This material absorbs unpleasant odours. In addition, it neutralises harmful gases such as volatile organic compounds (VOCs) and formaldehyde. The recommended lifespan of the filter is 6 to 12 months.
