It is suggested that the filter is replaced for a clean one four times a year so as to maintain good airflow inside the house. The actual dimensions of the air filter can not be a choice that needs to be made because of the constraint of whoever designed your heating and cooling system. LG LMAN120CNS filters come in a wide array of varieties and specific sizes, in which the one you choose will depend on your air quality needs and the specific size of filter you need for your system.
