Whirlpool ATR0942CPP0 Air Filter
HVAC specialists suggest the your furnace filter is changed four times a year due to the filter clogging up and restricting the flow of air inside the house. Air Filters exist in many different varieties and specific sizes, depending on your desire for cleaner air and the specific size of filter you need for your system. The dimensions of the filter is not a choice you make but rather a requirement of your furnace or handler.
Subtle hints your filter is not going to last much longer
- Manufacturers have advised to replace the filter about every three months to help keep the air fresh and make the unit run more efficient
- The system filter looks brown and probably should be replaced as soon as you can
- When you hold the filter up to the light, it will hardly show on the other side a clogged air filter
