Levoit Core 400S-P Smart Air Purifier, Auto Mode, 3-Stage Filtration For Large Room

Levoit Core 400S air purifier offers a 3-stage filter which can definitely assist with all kinds of particles. Smaller particles pass on to the second stage of the filter where these airborne contaminants are captured.

Depending on your air quality and how often you use your Core 400S air purifier, we recommend changing the filter every 6–12 months. 

If you live with high exposure to pollutants (airborne fur, dust, smoke, etc.), you may need to replace it more often. Your personal wellness needs may also affect how frequently you change the filter.

This filter does not have a detachable pre-filter, so it cannot be washed.

To maintain your filter, we recommend cleaning the pre-filter (outer layer of the filter) using a soft brush or vacuum hose every 2-4 weeks. Please do not use water or liquid to clean the filter, however. Trapped water particles may result in mold growth or mildew smells.

Depending on your preference, you can run the Core 400S air purifier 24/7 or even just a few hours a day.

With any electronic device, we also recommend supervising its use and turning it off if away for extended periods of time (such as leaving the house).
