Lennox CBX32M-018 Air Filter
It is advised that the air filter is swapped out four times a year due to the filter clogging up and restricting the flow of air through the ducts. The filter may filter out all the dust and other particles from the air handler as well as the home. The size of the filter is not really a choice you make due to the constraint of the availability of room of your air handler.
Do you know if your Lennox air filter is not well?
- The air filter looks dirty and maybe should be replaced right away
- If you hold it up to the light, it is unable to shine through to the other side of a dirt-packed filter
- It is highly recommended to replace the filter every 90 days so as to have cleaner breathable air
