Should Air Filters be Changed More Frequently in the Summer?

Should Air Filters be Changed More Frequently in the Summer? | Cool PowerYour air filter is the silent guardian of your HVAC system. It protects your system from the wear and tear of dust and other pollutants. It also takes care of your family, removing allergens from your air so you can breathe better.

From time to time, this warrior for indoor air quality needs to be replaced. All the dust and allergens build up and make it more difficult for air to pass through. This forces your HVAC system to work harder, using more energy and stressing the components of the system.

A dirty air filter also compromises the air quality in your home. Since cooled or heated air recirculates through the system, some of the allergens caught in the filter can work their way back into your home.

Many homeowners know they need to change their air filter, but they’re unsure of how often. They also ask whether they should change their filters more frequently during the summer.

In general, it’s a good idea to at least check your filter once a month. Most filters are good for up to three months under normal conditions. However, your filter will need to be changed more often, typically once a month, if:

  1. You’re using your A/C (or heating) system more than usual. For example, in the hottest part of the summer, your A/C may run most of the time. With the increase of air going through the system, you get an increase in pollutants caught in your filter.
  2. You have pets. Pet dander is a fact of life with most pets, and it’s usually worse in the hotter months when your pets are shedding. Luckily, your filter will remove a lot of it from your air, but that does mean you have to change your filter more often than many non-pet owners.
  3. You have allergies or asthma. Especially during prime allergy season in the spring and summer months, changing out your filters frequently can help your whole family breathe better.
