When Should I Change My Air Filter?

In order to keep your heating and cooling system functioning efficiently, it’s important to change the air filter on a regular basis—but just how frequently should you be swapping old filters for new?

Replacing the air filter can help you maintain positive indoor air quality and can even increase the lifespan of your HVAC system. By understanding more about when to replace your air filter, you can enjoy these benefits and more.

Swap Your Air Filter Once a Month

As a general rule, HVAC system air filters should be replaced each month. Although the once-a-month rule should be taken as a rule of thumb, there are different types of air filters, which may have different requirements for when they should be changed. Many air filters are sold with a manufacturer’s recommendation regarding replacement.

Factors That Can Impact This Rule

Regardless of whether you use the manufacturer’s recommendations or you follow the general rule of thumb, there are a few factors that can influence the frequency of your filter changes. For example, if you are in a climate that requires your system to run very frequently, the air filter may get dirtier than the filter used with a system that only occasionally ran during that same time period. Systems in homes with many occupants or pets may also get dirtier air filters.

What Else You Need to Know

Some homeowners will not follow these rules and will replace their air filter only when they notice that it is getting dirty. When dirt is visible on the air filter, the system is already having to work harder than necessary to force the climate-controlled air through the air ducts and filter. Therefore, it is best to follow these recommendations and make your own adjustments based on how many people and pets are in the home and based on how frequently your system runs.
