One of the common questions we are asked – particularly when someone doesn’t know the dimensions of their air filters is, what are the standard or most common filter sizes. We hope this quick reference chart will help you find just what you’re looking for…
Standard air filter sizes include:
10 X 20 14 X 20 16 X 24 18 X 30 12 X 12 14 X 24 16 X 25 20 X 20 12 X 20 14 X 25 18 X 18 20 X 24 12 X 24 14 X 30 18 X 20 20 X 25 12 X 30 15 X 20 18 X 24 20 X 30 12 X 36 16 X 20 18 X 25 24 X 24 25 X 25
Standard Air Filter Dimensions
Standard air filter sizes are cut nominally, which means they are 1/2 inch undercut, based on industry standards (just like disposable air filters you purchase at your local hardware store).
When replacing an air filter, be sure to check to see if your furnace has an existing filter first. If so, does it fit properly? Are the corners squashed or has the filter been forced into the system to fit?
Washable electrostatic air filters feature a durable steel frame – it is far more durable than flexible cardboard. A high quality permanent/washable air filter will outlast the life of your HVAC system. For example: A 10 X 20 filter will have actual dimensions of 9-1/2 X 19-1/2.
