ABSTRACT:
A pet litter container having a covering defines an interior space. A door opening in the covering allows for pet ingress and egress. A plurality of ventilation openings are provided in the covering. A power filter is located in fluid communication with the ventilation openings for removing and filtering odors from the air in the interior space. The power filter includes a power filter housing having an air inlet and an air outlet. An air path is defined by the power filter housing between the air inlet and the air outlet. A low voltage fan is mounted in the housing in the air path for moving air at a predetermined rate from the interior space, through the air inlet, and out the air outlet for exhausting filtered air from the interior space into an interior room in a house or an apartment. A self-contained filter cartridge is removably mounted in the housing in the air path for removing odors from the air in the air path. The power filter housing also includes retention means for releasably retaining the air inlet in fluid communication with the ventilation slots in the covering. In one embodiment, the filter cartridge is slidably mounted in a rectangular power filter housing and may be easily changed by sliding the filter cartridge out of an opening in a sidewall of the power filter housing. By using an adapter plate, the air inlet in the power filter housing may be used on a covering having ventilation openings with an alternate configuration.
