Abstract
A deodorizing air filter media which comprises a web of non-woven fibers having myriad discrete particles of a deodorizing component, such as sodium bicarbonate, uniformly dispersed throughout the thickness of the web. The media is fabricated by a two step process, wherein a non-woven web is passed through a first aqueous solution including a binder, and then dried to cured the binder and anchor the crossing points of the fibers in the web. Next, the dried web is passed through a second aqueous solution having a binder in a reduced concentration, together with a particulate deodorizing component suspended therein. The web is then again dried to cure the newly added binder and anchor the particulate deodorizing component to the fibers.
