How Often Should You Change Your Air Filter at Home?

Having clean air at home is key to living a healthy lifestyle and one of the best ways to do so is by ensuring you have clean air filters. In fact, when used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small place. Since they are designed to filter pollutants or contaminants out of the air that passes through them, they can help you gain cleaner air at home. While it’s fairly simple and quick to change these filters, many people don’t do it often enough. Developing a habit of changing out your older air filter for a fresh new one on a regular basis is important, but how often should you do so?


The type of filter makes a difference


While it would be great to have a standard answer for all air filters, not all air filters are the same and therefore there are a few factors you want to consider when determining the ultimate time frame between changes. First, you’ll want to know what type of filter you use, and Home Depot states that the most common types are fiberglass and pleated. 

While both types are disposable, fiberglass air filters are more affordable but slightly less efficient and should be changed every 30 days or so. Pleated air filters are a bit more expensive, but they are also more efficient at trapping particles and can go for up to 90 days without changing depending on use.  


Other factors to consider


In addition to paying attention to the type of filter you use, you’ll want to also think about other factors like the size of your home, the air quality outside, and the pets you have living with you. As a rule of thumb, larger homes with standard size filters often need to be changed more frequently due to the amount of air that is circulated through the furnace or AC unit. With more air comes more dirt and therefore the need for a more frequent change.

 When it comes to air quality, consider the amount of pollution surrounding your home. If you live in a dense area, like the center of a busy city, you may find your air filter becoming dirty faster. Finally, with pets, especially those furry friends that shed a lot of dander and hair, you’ll want to change your air filter more frequently to help keep your air quality good at home.


Don’t forget that the weather affects your filters


As the weather changes outside, you’ll naturally change the temperature at home to ensure you and your family are comfortable and therefore the frequency you need to change your air filter can fluctuate. With mild weather your system won’t be running as often and therefore won’t get as dirty. On the other hand, you’ll be likely to use your heating and cooling systems much more frequently in the height of winter and summer.
