Lennox XC15-030 Air Filter
The furnace filter filters out bad things in the air and other fine particles from the air inside the house. The actual dimensions of the filter is not really a choice of options due to the constraint of the availability of room of your HVAC blower system. It is highly recommended that the filter that filters out particles from your home is swapped out every 90 days or so for optimal air quality throughout the home.
What signals that my main filter is in need of replacing?
- When you face it toward a light, the light will barely show on the other side a dirt-packed filter
- It is highly suggested to replace your air filter every season of the year to help keep the air fresh and make the unit run more efficient
- The air filter looks dirty and perhaps should be replaced today
