Can I Use Both An Air Purifier And Humidifier Together?

Because both an air purifier and a humidifier perform completely different functions (removing pollutants from the air as opposed to adding moisture to the air), they can be used together, even in the same room. However, you should avoid placing them too close together because the moisture from the humidifier could clog filters or otherwise limit the effectiveness of the air purifier. For instance, if a HEPA filter were to be consistently damp because the output of a humidifier was directed into it, the dampness could promote the growth of mold or bacteria on the filter. This can avoided by placing them at opposite ends of the room.

To operate effectively, both air purifiers and humidifiers need to be properly maintained. For a humidifier, this means frequent cleaning. It’s also important to use distilled water with ultrasonic humidifiers to avoid adding mineral particles to the air, which might be harmful to your lungs, particularly those of young children and infants (Daftary & Deterding, 2011). For an air purifier, maintenance primarily means replacing filters regularly.
