LG ARNU123SEL2 Air Filter

Air Filters come in many filtering levels, which depends on your particular air quality needs and the specific size of filter you need for your system. The size of the filter is not really a choice you make but rather a requirement of whoever designed your heating and cooling system. It is highly recommended the your furnace filter is changed four times a year so as to maintain good airflow through the ducts.

It is highly advised to swap out your air filter about every 90 days to help prevent mold and bacteria build-up
