Trane XR15 Air Filter
Professionals in the industry advise the your furnace filter is changed every 3 months to maintain the best air quality throughout the home. The main filter should filter all the dust and other fine particles from the air handler as well as the home. The actual dimensions of the air filter can not be a choice of options because of the constraint of your HVAC blower system.
General warnings of a worsening dust filter
- If you place a light source behind it, the light will almost not show through the filter at all
- It is highly recommended to replace the filter every three months in order to have cleaner breathable air inside
- The filter looks bad and it would be a good idea to replace it ASAP
