How often to change residential or commercial air filters?

The frequency at which you should change your indoor air filters depends on several factors, such as the type of system, the filter you are using, the level of air pollution in your area, and the amount of usage your HVAC system receives. As a general rule of thumb, it is recommended to change your air filter every 1-3 months.

For homes with pets, allergies, or heavy foot traffic, you may need to change the filter more often. If you live in a particularly dirty environment, such as an area with high levels of air pollution, you may also need to change the filter more frequently. On the other hand, if you live in a clean environment and your HVAC system is not used frequently, you may be able to go longer between filter changes.

It’s also important to check your air filter regularly and replace it when it is dirty, regardless of the time elapsed since the last change. A dirty filter can reduce the efficiency of your HVAC system, leading to higher energy bills and reduced indoor air quality.
