Air washers are designed to help clean your air while providing healthy moisture to your space. This is a great benefit if you suffer from mild allergy or asthma symptoms. Often, air washer humidifiers use impeller technology during which a series of spinning plates continuously filter out large allergens and particles from incoming air. This prevents harmful impurities from being released into your breathing space. Alternatively, an air washer system may use a special air-washing pre-filter, similar to an air purifier pre-filter, to remove large particles before air is humidified and dispersed.

It's important to note that an air washer should not be depended upon solely to relieve moderate to severe allergy and asthma conditions. For these conditions, we encourage you to consider a HEPA air purifier, which uses an extensive filtration system to remove the microscopic allergens—those measuring as small as 0.3 microns—that will most often aggravate your symptoms. Air washers can be trusted to remove particles as small as 1.5 microns.
