It is advised that the filter that filters out particles from your home gets replaced every 90 days or so for optimal air quality in the home. All air filters come in a wide array of filtering levels, which depends on your particular desire for cleaner air and air handler requirements. The actual size of the air filter can not be a personal choice but rather a requirement of whoever designed your heating and cooling system.
Some warnings the dust filter needs a replacement ASAP
- Many pros have suggested to replace the filter four times a year to help prevent mold and bacteria build-up
- If you were to lift up the filter, the light will almost not infiltrate to the opposite side of the dirt filled filter
