People often ask me, "how do I know when to change my filter?" This is a very important question because if you wait too long to change your filter the air flow will be seriously restricted. Neglecting a dirty filter can reduce heating and cooling efficiency, increase energy bills, and may even cause air conditioning coil freeze-up and premature equipment failure. On the other hand, if you change your filter too soon, you waste money because you will not get the most out of your filter. Most people know the importance of regular filter maintenance. Yet the average homeowner rarely thinks about checking the condition of their furnace filter. Even regular visual inspection does not always reveal the true condition of a filter.
How The Clean Air Filter Gage Works As a filter becomes dirty, internal air resistance increases while air flow decreases. Initially, this restriction simply reduces heating and cooling efficiency. A further reduction in air flow will produce a more dramatic loss of performance. The Clean Air Filter Gage detects the reduced air flow and provides a visual indication of the need to replace the dirty air filter. Easy Installation The Clean Air Filter Gage is very easy to install...Anyone can do it. You do need to make a 1/4" hole in the duct or furnace. If you can't do this, your contractor can do it as part of your yearly system maintenance.
The Clean Air Filter Gage is An Automatic Maintenance Reminder The Clean Air Filter Gage consistently measures the condition of the furnace filter. When the indicator vane enter the "red" zone of the Air Filter Gage, it is time to clean or replace the furnace filter - it's that simple !
