Carrier FB4CNF036 Air Filter
Carrier FB4CNF036 filters exist in many different types and sizes, which all depends on your personal demands for clean air and the specific size of filter you need for your system.

The actual dimensions of the filter is not really a choice that needs to be made but rather a requirement of your air handler.
