Carrier FX4BNF042000 Air Filter
All air filters are made in lots of varieties and specific sizes, which all depends on your personal choice for how clean you want the air and the specific size of filter you need for your system. It is suggested that the filter that filters out particles from your home is replaced for a clean one every 3 months so as to maintain good airflow inside the house. Exact measurements of the filter is not a choice you make because it is based on the declared size of your air handler.
