Since AC and furnaces are used more in the peak seasons, air filters have more work to do by filtering the harmful particles. This is when micro allergens, dust particles/toxins, and other pollutants start to build up on your furnace and AC filters in a matter of a few months. It results in clogging your filters and restricting the quality of airflow. So, we recommend replacing the air filters every 2-3 month and every month during the peak seasons.
