ABSTRACT:
A filter retaining device to prevent a unit filter from inadvertently falling out of a bottom access flow-through housing when the housing is opened to gain access to the interior. Bottom access flow-through filter housings typically include spaced apart elongated channels which slidably receive a unit filter. These channels serve to locate and hold a unit filter in a gas stream passing through the flow-through housing. The filter retaining means is removably attached to the bottom open end of each channel to support the unit filter in the flow-through housing when the bottom access is opened to gain access to the interior of the filter housing.
