Goodman GPC1442H41AB Air Filter
Air Filters come in many filtering levels, which depends on your particular choice for how clean you want the air and the specific size of filter you need for your system. It is suggested the your furnace filter gets replaced every 90 days or so as to maintain good airflow throughout the home. The height, length and width of the air filter can not be a personal choice due to the requirement of your HVAC blower system.
Subtle cues of a failing main filter
- With a light behind the air filter, the light does not shine through to the other side of the filter
- It looks brown and could be replaced as soon as humanly possible
- Manufacturers have suggested to replace the filter four times a year to help clean the indoor air
