| There is a red circle on my air purifier's panel. | It is time to change the main filter. | 1. Change filter according to the instructions in this guide. 2. Reset the filter life timer: press down the fan speed button until the red light disappears (15 seconds). |
| My air purifier is making too much noise. | Air purifiers that are set on a high-speed level produce more noise because they function at faster rates. The plastic sealing is still on the filter. If the main filter or pre-filter are clogged or dirty, the engine might not get sufficient airflow, which may result in increased noise levels. |
Set a lower fan speed. The air purifier should be quieter. 1. Remove the main filter according to the instructions in this guide. 2. Make sure that the plastic cover is removed from the filter. Unplug your air purifier and vacuum the air purifier and its fabric pre-filter from the outside with a soft brush attachment. Clean the fabric pre-filter in the washing machine.
