What if I Use My Furnace Without an Air Filter?

Furnace Without an Air FilterWe’ve said it here at Bell Brothers and we’ll say it again, the best thing you can do for your furnace is to regularly check and change your air filters. Though we often repeat the importance of this to homeowners, we still hear the same question, “can I use my furnace without an air filter?” Today, we’re taking some time to answer that question. The short answer is yes, you can run your furnace without an air filter. However, we’ll explain why this is a terrible idea, and you should always run your furnace with an air filter.

If your Use Your Furnace Without a Filter You Risk Poor Air Quality

We always tell people, one of the most important things an air filer preserves is their health. Oftentimes, an air filter is the first line of defense against indoor air contaminates. This alone should be reason enough to not run your furnace without an air filter. In many ways, your HVAC system acts as an air recycler recirculating the same air inside your home. It pulls air within your home through return vents, runs the air through the furnace or condenser, then releases the now climate treated air back into your home. With each pass through the system, the air must go through the air filter, which removes dirt, dander, and other air contaminates. Without a filter, indoor air contaminates are inhaled by you and your family or left to create a buildup in your furnace or ductwork.

You Could Be Contaminating the Ductwork if You’re Using Your Furnace Without an Air Filter

As we mentioned above, if left unfiltered, indoor air contaminates can make a home inside your ductwork. This is bad because any air that circulates through your home must first pass through your ductwork. This ductwork plays a major role in the quality of your indoor air. Any treated air that’s dispersed through your home must first pass through your ducts. Using your home furnace without an air filter means your ducts could easily foster mold growth. When debris is allowed to accumulate in your ductwork it can attach itself to the aluminum tubes and foster the perfect environment for mold growth.

You Even Run the Risk of Ruining Your Furnace

Air filters aren’t just for your protection. They not only protect your health, but they also protect your entire HVAC system. Believe it or not, an air filter’s first purpose was to protect the system, not the people breathing the treated air. Generally, furnaces are put in dusty places. If you were to use your home furnace without an air filter, all that dust and debris could get stuck in your system and cause a rather large buildup. The effect of this buildup can be a damaged system. To save yourself from large repair bills—or even from having to buy a new system—we recommend running your system with a clean air filter.

Air Filter Tips and Tricks

When it comes to the care and keeping of your HVAC system, the best thing you can do is to regularly change and check your air filter. At Bell Brothers, we recommend changing your air filter twice per year, once for furnace season and then AC season. If you have hairy pets, you may want to change it more often. If you don’t feel comfortable checking the air filter yourself, ask an HVAC tech the next time he is over for a tune-up or repair.
