Carrier 50CE Air Filter
It is suggested the your furnace filter is swapped out four times a year to maintain the best air quality inside the house. Measurements of the filter is not really a choice that needs to be made because it is based on the declared size of the manufacturer of your system. Air Filters come in many styles and sizings, which all depends on your personal desire for cleaner air and air handler size requirements.
What to see if the main filter is about to stop working?
- Sunlight does not penetrate through a dirty filter
- Many pros have suggested to replace the filter about every three months to assist in keeping the indoor air clean and fresh
- The main filter looks bad and it would be best to replace it without delay
