When Should I Replace My Air Filter?

Every homeowner knows they’re supposed to routinely change their HVAC air filters, but not everyone knows when. Truthfully, the time when you should change an air filter can depend on many different factors, including the type of air filter you have and if there are any pets living in your home.

Below, we provide plenty of information for those asking themselves, “How do I know when to replace my air filter?”

Why change your air filter

Routinely changing your HVAC air filters promotes good air quality within your home. You don’t want dust, pollen and other allergens constantly cycling throughout your home. This would be terrible for you and your family’s health.

Changing air filters also helps ensure the longevity of your HVAC system. When your air filters are clogged with dust and other allergens, your HVAC system has to work harder. This puts a lot of strain on the system, which will likely result in it breaking sooner than expected.

Neglecting to change your air filters on time often results in higher energy bills. An HVAC system with dirty air filters can’t effectively heat or cool your home, meaning you’ll have to run it longer to keep your home at a comfortable temperature.

What type of air filter do you have?

One of the first things to consider when asking yourself, “When should I replace my air filter?” is the type of air filter you have. Most homes and apartments come equipped with fiberglass HVAC air filters. These are the air filters you can find in just about any supermarket for around $10 a pack. Most experts recommend changing these air filters once a month.

Washable air filters have become more common these days, as they prevent the need to constantly buy new air filters. You just need to wash them after noticing a large presence of dust and dirt. Some washable air filters can last over five years before needing a replacement.

If you have pets

If you have pets, your air filter might need changing more frequently than homes without pets. This is because pet hair can easily get caught in the air filter, which only adds to the layer of dust and other allergens. Check your air filter more frequently if you have pets. You still may only need to change them around once a month.

Does anyone in your home suffer from respiratory issues?

It’s important that those suffering from respiratory issues, like asthma, live in a home with good air quality—that means changing your HVAC air filters at least once a month. It might also be a good idea to invest in an air purification system if you or someone in your home suffers from allergies or asthma.

Don’t put off changing your air filters

As you can see, it’s extremely important to know when to replace your HVAC air filter. Doing so can help save energy, prevent allergy symptoms and much more. It’s also a good idea to have your HVAC system routinely inspected by a professional.
