Lennox XC16 Air Filter
All air filters come in many varieties and specific sizes, in which the one you choose will depend on your demands for clean air and air handler requirements. The size of the filter is not really a optional choice because it is based on the declared size of your air handler. It is suggested that the air filter is exchanged for a new one every 90 days or so to maintain the best air quality inside the house.
