Changing out your air filter is an easy and relatively inexpensive way to maintain your HVAC system and your home’s indoor air quality.

What Function Does Your Air Filter Serve?

Your air filter acts as a barrier to remove dust, debris, pet hair, bacteria, and mold from being circulated around your home or entering your HVAC system. This means that changing your air filter out on a routine basis is important for both your indoor air quality and the life expectancy of your HVAC system.

How Often You Should Change Your Air Filter

In order to work properly, your air filter should be changed out on a routine basis. We generally recommend changing out your filter every 30 to 90 days. However, there are other factors that are individual to your home that can affect the efficiency and lifespan of your air filter.

Factors That Can Affect How Often to Change Your Filter

The biggest determiner of how often to change your air filter is the type and quality of the filter that you use. Generally, cheaper filters need to be changed out more often. Additionally, the more dust, dirt, pet hair, and other debris that is in your home, the more often you should change your air filter. This means, homes with pets may need to change their air filter out more often than homes without.

If someone in your home suffers from allergies, you may want to consider using a high-quality HEPA air filter that is designed to remove allergens from the air. You’ll also want to change out the air filter more frequently to help ease their allergies.

Lastly, how often you use your HVAC system also impacts how long your air filter will last. For homeowners who use their air conditioning or heating system every day, they will want to consider changing out their air filter more often than those who do not use it as often.

What Happens If You Don’t Change Your Air Filter Often Enough?

If you aren’t changing out your air filter often enough, it can have several major impacts. First, your indoor air quality will suffer. There will be more allergens in your air and it may become more difficult for your HVAC system to push air through the filter. This can put more stress on your HVAC  system and cost you more in energy bills. Additionally, your air filter also protects your HVAC system from dust, dirt, and debris, so failing to change it can actually shorten the life expectancy of your system.
