Samsung AVMKH020EA0 Air Filter
It is highly recommended the your furnace filter is changed every 3 months so as to maintain good airflow through the ducts. The measurement proportions of the filter is not really a choice you make but rather a requirement of your system. Air Filters are available in many filtering levels, in which the one you choose will depend on your demands for clean air and air handler size requirements.
Major signs of a failing main filter
- It is recommended to replace the filter every three months for clean air inside the house
- If you were to lift up the filter, the light will barely shine on the opposite side of a dirty filter
- The system air filter looks dirty and maybe should be replaced soon
