发明名称 HVAC filter changing system
摘要 An air conditioner filter removing system for air filters located in elevated return-air vents, such as return-air vent mounted in a ceiling or upper wall. The device consists of a filter-grabbing mechanism that can be mounted to an extension pole. The filter-grabbing mechanism has teeth protruding from it to grab an air filter and a holding plate where the filter is balanced once engaged by the teeth. In its preferred embodiment, the system has one or more magnets for holding the return-air vent door closed so the filter-grabbing mechanism can easily pull the vent open. Further, the preferred embodiment also has kicker plates that help removal of the teeth out of the grill louvers they are inserted into, on the vent door.
