An air washer is actually a surprisingly simple device, although the specific mechanisms of how they work are much more complex. During the air washing process, contaminated, polluted, or dry air is taken into the device through suction; then, the air washer uses a basic evaporation process to collect contaminants from the air and separate them.
The air passes over several metal plates and absorbs water particles simultaneously; this helps humidify the air while also removing any nasty contaminants. As such, at the end of the process, the purified air is released back into the property – taking some of the water droplets with it – and the process repeats for the next suction of air.
There are numerous different air washers on the market, and these all work a little differently. Some, for example, offer even greater levels of purification by first passing the air through an incredibly fine mesh filter. This increases the potential purification potential for the air washer, which could make it a good option to consider for properties in highly polluted regions.
