So, during the whole year, you want your air conditioning to run smoothly with the best performance. Therefore it is optimal to change your filter once a month during spring and summer months and every two months during fall/winter. Yet, it’s also essential to monitor your filter. If you notice it’s dirty, change it. Please don’t wait one more week because it hasn’t been a month yet.
A dirty air filter can cause problems for our health, especially if anyone in your home has allergies. The EPA lists indoor air pollution as “one of the Top 5 risks to overall health.” Also, a dirty filter causes a restriction to the airflow, causing the HVAC unit to work harder. Not replacing your filter could be very costly in the long run.
The good thing is that Air filters cost only a couple of dollars to replace. Changing your filter is the most accessible and most inexpensive thing you can do to improve air quality inside your residence.
