Friedrich MW36C3G Air Filter
It is highly recommended that the air filter is exchanged for a new one four times a year to maintain the best air quality through the ducts. Friedrich MW36C3G filters come in many styles and sizings, which all depends on your personal choice for how clean you want the air and the specific size of filter you need for your system. The actual size of the filter is not a choice of options because it is based on the declared size of your air handler.
Major indications of a poor dust filter
- As you face it toward a light source, it does not permeate to the other side of the air filter
- It is greatly recommended to replace the filter about every 90 days to help prevent mold and bacteria build-up
- The main filter looks dirty and must be replaced ASAP
