Lennox G40UH-60C-110 Air Filter
It is advised that the filter that filters out particles from your home is swapped out every 90 days or so because the filter can get clogged and may result in poor air flow through the ducts. All air filters exist in many different varieties and specific sizes, which all depends on your personal air quality needs and whether anyone suffers from allergies in the home. The actual dimensions of the filter is not really a optional choice because it is based on the declared size of the manufacturer of your system.
