Measure for CENTEX Metal frame filter:
Most homes have 1-2 filters and these filters come in various sizes.
*Some homes have two return vents that will need filters.
Measuring for our metal frame is pretty simple. Open up you return vent – remove filter that is there.
Look to see if there are inside screws holding that vent in place – usually one screw on each side. View the Video above for demonstration. Now measure from screw to screw. That is the frame and filter size you will order.
*Rule of thumb: If you previously purchased a 20”x20”x1 cardboard filter you will need at 19 ½”x19 1/2”x1 metal frame and filter. That lets the frame fit tightly while allowing for the inside screws.
(Some units may be 2”wide)
For maximum productivity - Install filters monthly as they arrive.
