International Comfort Products CXA230AKA1 Air Filter
All air filters exist in many different filtering levels, in which the one you choose will depend on your desire for cleaner air and air handler size requirements. The actual size of the filter is not really a personal choice due to the requirement of your air handler. Professionals in the industry advise the your furnace filter is changed four times a year to maintain the best air quality through the ducts.
Major clues of a weakening dust filter
- Manufacturers have suggested to replace your air filter every three months to help clean the indoor air
- If you place a light source behind it, the light is unable to permeate to the other side of a clogged air filter
- The system air filter looks very bad and it would be a good idea to replace it immediately
