Dust, pollutants, and allergens make themselves right at home inside your air filter. As a renter or homeowner, it’s usually your responsibility to stay on top of changing out your filter regularly but our survey found that most Americans aren’t keeping up. 

Changing your filter regularly can help reduce energy consumption, save you money and help keep the air quality of your home clean. Two-thirds of American households have air conditioning systems, but after surveying 1,000 people to ask how often they change the air filter in their home, we found that a shocking amount of people admit to some dirty habits. 

Our findings revealed:

  • Twenty-nine percent of Americans never change their air filter in their home. 
  • The majority of Americans (82 percent) fail to change their air filter monthly. 
  • Of those who do change it, most people (31 percent) only change it every few months.

If you’re guilty of forgetting to replace your air filter on a regular basis, you’re not alone. We found an overwhelming majority of people (82 percent) responded that they fail to change their air filter monthly. Changing your filter monthly ensures that you aren’t allowing allergens and dust to keep circulating into your home, creating cleaner air for your family. 

Nearly half of people (43 percent) felt it was extremely important to change the air filters in their home, yet only 18 percent of people change their air filter once a month. As our lives get busier, regular home maintenance falls down on our to-do list, especially when we aren’t aware of any issues. However, if you’re a pet owner, you know just how much dirt and fur can accumulate on your floor, furniture and clothing. Have you ever thought about how that affects your air quality?

 

Not changing your air filter can cost you

As a renter or homeowner, there are many repairs and maintenance to keep up with. This means there are also many costs associated with having a safe and protected home. If you still aren’t convinced that your air filter needs to be replaced regularly, you might be missing out on savings, both in energy bills and repair costs.

Why it’s important to change your air filter regularly

 

By now, you’ve learned that regular maintenance can help you avoid certain costs. In addition to saving money, changing your air filter on a routine basis can provide eco-friendly rewards and potential health benefits.

  • Clean air: Air filters help trap air particulates and may help people living with respiratory issues breathe easier. Although air filters can’t prevent all harmful particulates from circulating through your home, the evidence can be seen in the dirty filter you replace each month. 
  • Save energy: According to the Department of Energy, regularly changing your air filter is the easiest way to reduce energy consumption. They report that you can save anywhere from five to 15 percent of energy consumption with a clean filter. Go green by staying clean.
  • Save money on bills: This goes hand in hand with saving energy — if you’re reducing your energy consumption, your utility bill should also reap the benefits. 
  • Save money on repairs: Your HVAC system works hard to heat and cool your home. Help it run efficiently by changing the filter regularly so that it doesn’t work harder than it needs to. 

 

How often should you change your air filter?

You may be wondering how often you really need to change your air filter, and the answer is that it varies. Most air filter products recommend changing monthly to maintain an efficient HVAC system and clean air quality. Some households may be able to get by changing it every 90 days or so, depending on whether or not they have pets or severe allergies. Other factors include the quality of the air filter and how often you use your AC system. 

Your air filter helps trap small particles of dust, pet dander, and pollen among other things. If your air filter is obviously dirty when you go to change it, you might want to consider checking it more often and replacing it as necessary.
