Can Furnaces Run Without Filters?

Your furnace filter has two primary purposes. One reason is important to your health while the other affects the performance of. your furnace. While running your furnace without a filter for one day probably won’t result in a noticeable change, continued operation without a filter in place can.

What the Purpose of a Filter?

If you’re like many homeowners in the Chandler and Tucson, Arizona areas, you probably equate your furnace filter with keeping your indoor air quality at its best. The filter stops any dander, debris, or dust from reentering your home once it is removed by your heating system. This improves the air you breathe inside and can reduce allergens too.

The other purpose of a filter is to keep those particles mentioned above from entering your furnace. Over time, this kind of debris can build up and cause your furnace to malfunction. At the very least, your furnace components will need more frequent cleaning if you run it without a filter.

What Can Happen if You Run Your Furnace Without a Filter?

As stated above, running your furnace for one night without a filter in place isn’t going to lead to a breakdown in your furnace. Doing so for longer than a day or two, though, will introduce debris that could lead to your furnace malfunctioning. You could also find any allergies or nasal congestion worsening if you continue to run your furnace without the protection of a filter.

Furnace Filter Maintenance

It’s also important to change your furnace filters on a regular basis. While the standard advice is to do so at least once per month, the frequency really depends on your particular situation. For example, if you live in an area that is very dusty or if you have a family member living in your home that has a compromised immune system, you will probably want to change it more often.
