Air Filter Alert Inc.: Air Filter Monitor

November 28, 2003
The Air Filter Alertâ„¢ monitor reminds homeowners to replace or clean furnace air filters. According to the manufacturer, the device easily attaches to a return air vent. Then an electronic tone sounds either after a programmed number of months have passed or the filter gets dirty, whichever comes first. A filter is determined to be dirty when it is detected to have a 20 percent reduction in airflow from the time the detector was last reset. Two AA batteries are included.
