  • Filter sensing apparatus and filter therefor
    Patent number: 5378254
    Abstract: An air treatment system has a removable and replaceable filter, the filter having a plastic frame, and having a multi-layer filtering medium. A filter seat has a switch located along one side in contact with a flexible tab. When the filter is located in the seat and faces the desired direction, one of two projections on the top and bottom of the filter frame moves the flexible tab to activate the switch, which signals proper installation of the filter. When a filter element is installed, it starts a timer which times the service life of the filter element and an air treatment cartridge. When the timer times out, it signals a user through an LED or audible alarm to replace the replaceable components.
