CAUTION: Do not place order using the measurement of the disposable fiberglass pad. Measure the outside frame or refer to filter label inside the c-channel at the top of the filter frame.

These Dynamic Sales HVAC replacement filter pads utilize a full sheet of activated carbon inserted between two sheets of fiberglass media, giving it the ability to be installed in any direction since the power-head probe will always contact the full sheet of activated carbon.
