As a general rule, HVAC air filters should be replaced every one to three months (or every 90 days). However, the ideal frequency depends on several factors, including the filter type and your home's environment. For instance, if you use thinner filters (1-2 inches deep), have pets, have household members with allergies, smoke indoors, or frequently keep windows open, you may need to change the filter as often as once a month. It's best to follow the manufacturer's recommendation as a guideline and visually inspect the filter monthly to see if it's dirty. Regular filter changes are crucial for maintaining proper airflow, good indoor air quality, and efficient HVAC system operation.

If you don't regularly change your HVAC air filter, it will become clogged with dust, dirt, and other contaminants. This blockage forces the system to work harder to circulate air, leading to several negative consequences. You may experience higher energy bills, poor temperature regulation, reduced air quality, and slower system performance. Over time, this added strain can cause parts to break more frequently, lead to system failure, and ultimately shorten the lifespan of your entire HVAC unit. In some cases, it can also contribute to health problems. It's recommended to change the filter at least every three months.

Air filters with a MERV rating of 11 or higher need to be changed every three to six months. If your filters are incredibly strained because of environmental factors, such as living in a smoggy, pollen-rich area with a large household, you may need to change your filters every two months regardless of the MERV rating.
