Trane TTZ048A100A1 Air Filter
The filter should filter bad things in the air and other particles from the furnace. It is recommended that the filter that filters out particles from your home is swapped out four times a year because the filter can get clogged and may result in poor air flow through the ducts. Measurements of the air filter can not be a optional choice because of the constraint of your system.
Clues to watch for to know your main filter is not going to last much longer
- The main filter looks gray or brown and it would be best to replace it right now
- Many pros have recommended to switch out the air filter in your unit every three months to keep the air fresh for the family
- As you face it toward a light source, it does not shine through the filter at all
