To clean your air purifier you should turn off and unplug the unit, remove the front panel and take out the pre- filter and HEPA filter, vacuum the pre- filter to remove dust, wipe the exterior and the interior of the unit with a dry soft cloth, then you can reassemble the unit and plug it back in.

The noise level varies with the speed setting. On the lowest setting, it operates quietly enough for night-time use, making it suitable for bedrooms or living rooms without causing disturbance.

Filter replacement frequency depends on usage and air quality. Typically, the HEPA filter should be replaced every 12 months, while the pre-filter may need to be replaced more frequently, every 3 to 6 months, to maintain optimal performance.
