Whirlpool ATE1245SPP0 Air Filter
All air filters are made in lots of filtering levels, depending on your choice for how clean you want the air and air handler requirements. The actual size of the filter is not a choice you make because it is based on the declared size of the manufacturer of your system. Professionals in the industry advise the your furnace filter is changed every 3 months so as to maintain good airflow inside the house.
Clues to watch for to know your Whirlpool air filter is not going to last much longer
- The air filter looks brown and must be replaced as soon as you can
- It is suggested to swap out your air filter four times a year in order to have cleaner breathable air inside
- If you hold it up to the light, it does not shine through a dirt-packed filter
