Whirlpool ATE1253CPP0 Air Filter
Professionals in the industry advise the your furnace filter is replaced for a clean one four times a year so as to maintain good airflow in the home. All air filters come in a wide array of styles and sizings, in which the one you choose will depend on your air quality needs and the specific size of filter you need for your system. The size of the filter is not really a choice of options due to the requirement of your system.
Major signs your filter needs replacing
- When you hold it up, the light will barely show through a dirt-packed filter
- Many pros have suggested to switch out the air filter in your unit about every 90 days to help prevent bacteria from spreading too much
- The main filter looks brown and probably should be replaced soon
