Please check whether the size of the usage environment matches the purifier's applicable coverage area and selected fan speed;The room's airtightness and ceiling height can also affect the purification effectiveness;Confirm that the filter is installed correctly and that its protective plastic packaging has been completely removed;If the filter has been used for an extended period, it can be saturated or clogged. Please replace it with an official filter;Ensure that the air inlet and outlet are not blocked by walls, curtains, or other objects, and keep at least 20 cm of clearance;Keep doors and windows closed while using the purifier, as outdoor air exchange will reduce efficiency;Check whether the particle sensor is dusty. If so, clean it gently with a dry cotton swab to ensure accurate readings;In environments with heavy smoke, pet hair, or dust, purification will take longer to reach optimal results;If the problem persists, please contact after-sales support for inspection.
