Whirlpool ATR0742CPP0 Air Filter
Air Filters come in a wide array of filtering levels, which all depends on your personal choice for how clean you want the air and whether anyone suffers from allergies in the home. The height, length and width of the filter is not really a optional choice due to the constraint of the availability of room of your air handler. It is highly recommended that the air filter is exchanged for a new one every 3 months because the filter can get clogged and may result in poor air flow in the home.
Major symptoms to watch for in a bad air filter
- The air filter looks like it is filled with dust and it would be best to replace it right now
- When you hold the filter up to the light, it will barely permeate to the other side of a dirt-packed filter
- Many pros have suggested to switch out the air filter in your unit about every 90 days to help keep the air fresh and make the unit run more efficient
