Do you have the need not only to regulate the level of relative humidity, but also to purify the air? There is no need at all to purchase two separate appliances to accomplish that! An air washer is a device that both purifies and humidifies the air at the same time.
Air washers are distinguished by devices with a built-in filter used to accomplish purification and devices where the cleaning process occurs via plastic discs. A built-in fan blows air fr om the outside to the inside of the air washer, wh ere it is purified with water and delivered back to the room, cleaned and humidified. Air washers can trap organic particles larger than 10 microns.
