International Comfort Products HHP448GKA1 Air Filter
Filters come in many filtering levels, depending on your desire for cleaner air and whether anyone suffers from allergies in the home. The actual size of the filter is not really a choice of options due to the constraint of the availability of room of your system. It is suggested the your furnace filter gets replaced every 90 days or so to maintain the best air quality throughout the home.
Red flags the air filter needs a replacement ASAP
- As you face it toward a light source, it will barely infiltrate to the opposite side of a very dirty air filter
- The unit air filter looks like it is filled with dust and should be replaced without delay
- Manufacturers have advised to switch out the air filter in your unit four times a year to help purify the air indoors
