When’s the last time you thought about your air filter? Working as HVAC experts in Greenville, NC, Washington, NC, and Blounts Creek, NC, we get asked the following question a lot:

“Does my air filter need to be changed? And how often?”

The answer: Yes. You need to change your heating and air conditioning air filter. It is absolutely critical for your HVAC system to perform properly, not to mention your home’s air quality. According to the EPA, indoor air pollution is one of the top five environmental health risks. Changing the air filters keeps your family safe.

The good news is that it’s not that hard to change an air filter. There are usually just two challenges to actually completing this job:

  1. Knowing how often you should change it.
  2. Always Remembering to do it.

What to Remember

It sounds easy but, when your air filters are dirty, you need to change them. Knowing when this the case, without opening the hatch, comes down to a couple of factors:

  • Type of filter your A/C system needs
  • The overall air quality of your home
  • Whether you have Pets – Birds, cats, dogs, hamsters, etc.
  • Number of people living in the house
  • The air pollution in your city area or whether construction is taking place nearby

For your typical 1″-3″ air filters, the manufacturer specs basically say to change them bi-monthly, which is, in fact, a great rule to follow.

However, this is not necessarily applicable to all. If you have light to moderate allergies, you may need to upgrade the air filter or change them even more regularly than OEM specifications. On the other hand, if you’re in a remote area, a seldom occupied vacation home, or an area where there are fewer cars around, replacing your air filters just once each year may actually be absolutely fine.

When Filters Should Be Changed:

Here’s how air filter changing breaks down for every situation:

  • Seldom used home or single occupant homes without pets or allergies: Every 6-12 months
  • Typical suburban home without pets: Every 90 days
  • Add a dog or cat: Every 60 days
  • Multiple pets or have allergies: Every 30-45 days
