Product details
The Xiaomi Smart Air Purifier 4 Lite Filter is a replacement filter for the Xiaomi Smart Air Purifier 4 Lite. It provides the filtering element used inside the compatible purifier, making it a practical spare when the installed filter reaches the end of its useful life. This listing contains a replacement filter and user manual; the air purifier itself is purchased separately.
Its cylindrical format measures 200mm in external diameter and 310mm in height. Xiaomi lists the filter colour as black. The official hardware model is M17-FLP-GL. These dimensions and the compatible product name help distinguish this filter from replacements for other purifier sizes. Check the name on your existing appliance before ordering, rather than relying on a similar-looking filter or a shared brand alone.
The filter combines three stages: a primary filter, Xiaomi’s high-efficiency filter material and activated carbon. The primary layer collects larger debris such as dust, hair and fine crumbs. The high-efficiency layer targets smaller airborne particles, including PM2.5 and pollen, while the activated carbon layer adsorbs odours. Together, the stages provide a single integrated replacement element.
Xiaomi specifies 99.97% filtration of particles measuring 0.3 micrometres for its tested filter material. The published percentage describes laboratory filter-media performance; results in a room depend on the purifier’s operating conditions, placement and surroundings. The filter uses mechanical filtration and electrostatic technology. It should be used in the appliance for which it was designed.
Xiaomi recommends replacing this filter every six to twelve months. That interval is a guide rather than a guaranteed service life for every home. Filter performance changes with use, and the Xiaomi Home or Mi Home app can show the compatible purifier’s filter usage and replacement estimate. Check the appliance’s reminders and follow its manual when changing the filter.
The package includes one xiaomi smart air purifier 4 lite filter and one user manual. Keep the instructions available during replacement, confirm that the new element is properly seated, and close the purifier’s filter compartment before returning the appliance to service. Choose this replacement specifically for the Xiaomi Smart Air Purifier 4 Lite; compatibility with other purifier models is not specified.
