Abstract
The invention is directed to a direct replacement air filtration or handler filter that is placed within an air flow channel within an air handler unit having a housing. A motor in communication with a controller and having an at least one sensor input or a timer or a transceiver and processing module. A filter media storage area is located on one end of the housing, with a pleated, folded filter media folded and compactly stored inside the filter media storage area. An exposed filter media containment area is located on an opposed end within the housing with the filter media extending therebetween. The filter media being paid out or advanced from the filter media storage area across the housing where it is exposed to air within the air flow channel as it removes contaminants from the air. The motor can be activated by said controller in response to input from the at least one sensor or based on a timed input from said timer and rotate an at least one movement member to move the filter media across the exposure area. This allows for higher efficiency operation and reduces maintenance and energy costs. The sensors and communications capability allow for the use of the filter in prov…
