Lennox CBX32MV-048 Air Filter
All air filters are available in many varieties and specific sizes, depending on your demands for clean air and the specific size of filter you need for your system. The dimensions of the filter is not really a choice of options but rather a requirement of your system. It is highly recommended the your furnace filter is swapped out every 90 days or so due to the filter clogging up and restricting the flow of air inside the house.
What are some hints that my air filter really needs to be replaced?
- The filter looks gray or brown and should be replaced without delay
- It is highly recommended to replace your air filter every 90 days in order to have cleaner breathable air inside
- If you hold it up to the light, it will not breach the other side of a dirty filter
