Why is the airflow reduced in my Levoit EverestAir LAP-EL551S-AUS?

  Reduced airflow can occur for several reasons. Ensure the filter's packaging has been removed and that it's correctly installed. Try increasing the fan speed. Make sure there's at least 15 inches / 38 cm of clearance in front of the air purifier. The pre-filter might be clogged with particles like hair or lint, so clean it. If none of these steps help, consider replacing the filter.

  Unusual noises from your air purifier can stem from a few causes. Check that the filter is correctly placed and that all plastic packaging has been removed. Ensure the air purifier is sitting on a hard, flat, level surface. You may need to replace the filter. If the noise continues, the air purifier may be damaged, or there could be a foreign object inside. In this case, stop using the air purifier and contact Customer Support.

Maintenance Features:

Cleaning the Smart Air Purifier: Unplug before cleaning. Wipe the exterior with a soft, dry or damp cloth. Vacuum the interior. Do not use abrasive chemicals or flammable cleaning agents.
Check Filter Indicator (FILTER Button): Lights up to remind users to check the filter, typically after 12–15 months of use. The VeSync app also provides filter life percentage and notifications.
Resetting the Check Filter Indicator:
- If the FILTER light is on (indicating it's time to check/replace the filter): Replace the filter, turn on the air purifier, then press and hold the FILTER button for 3 seconds to reset. The indicator light will turn off, and filter life will show 100%.
- If the filter was changed before the FILTER light came on: Press and hold the FILTER button for 3 seconds until it flashes, then it will stop flashing and turn off, showing 100% filter life.
Cleaning the Pre-Filter: Should be cleaned every 2–4 weeks. Remove the front cover and pull out the pre-filter. Clean with a soft brush or vacuum hose to remove hair, dust, and large particles. Optionally, wash with water and mild detergent, then air-dry completely before reinserting. Avoid scrubbing or using abrasive materials.
Replacing the True HEPA / Activated Carbon Filter: Recommended every 12–15 months, or sooner depending on usage and pollution levels. Unplug the air purifier, remove the front cover, and remove the old filter. Vacuum any remaining dust or hair inside the air purifier. Remove plastic packaging from the new filter, insert it, replace the front cover, plug in, turn on, and reset the Check Filter Indicator. Only use official Levoit filters.
Cleaning the AirSight Plus 2.0 Laser Dust Sensor: Clean every 3 months, or more often in dusty environments. Unplug the air purifier, place a vacuum cleaner end over the sensor openings, and turn the vacuum on for at least 10 seconds to clean out dust.
Storage: If storing for an extended period, wrap the air purifier and filter in plastic packaging and store in a dry place to prevent moisture damage.
