Units designed to cleanse indoor air with out counting on conventional particulate filters characterize a selected class inside air purification know-how. These programs make use of various strategies, equivalent to ionization, UV gentle, or photocatalytic oxidation, to take away or neutralize airborne contaminants. For instance, an air air purifier utilizing a UV lamp to inactivate microorganisms falls into this class.
The importance of this know-how lies in its potential to scale back reliance on disposable filters, resulting in decreased waste and, doubtlessly, decrease long-term working prices. Traditionally, these programs have been explored as options in environments the place filter substitute is difficult or the place particular kinds of contaminants, equivalent to unstable natural compounds (VOCs), require totally different therapy strategies than easy filtration.
