ABSTRACT:
An integrated air filtration unit includes a support structure for mounting a V-shaped filter bank to an air passage of an air handling system. The V-shaped filter bank may be moved from a working position in which the air is filtered to a service position in which a pair of filter pads in the filter bank can be accessed for service or replacement. The integrated air filter unit may include an ultraviolet irradiation system for destroying airborne micro-organisms trapped by the pair of filter pads.
