Goodman GCH90905DX Air Filter
Air Filters exist in many different varieties and specific sizes, depending on your desire for cleaner air and air handler requirements. It is highly recommended that the filter is replaced for a clean one every 90 days or so due to the filter clogging up and restricting the flow of air through the ducts. The dimensions of the filter is not really a choice of options because it is based on the declared size of your HVAC blower system.
Important signs your filter probably needs to be replaced
- The air filter looks dusty and must be replaced as soon as humanly possible
- Professionals have advised to switch out the air filter in your unit four times a year in order to have clean air running through the unit
- Light will barely show through the air filter
