A furnace filter may seem like an insignificant, not-all-that-necessary thing, but the filter is actually a critical part of keeping your furnace operating. Furthermore, keeping a furnace filter in your system is going to keep your air quality at a healthy level.

Here’s what you need to know about operating your furnace without a filter in place:

A Look at the Purpose of a Furnace Filter

A furnace filter is a simple thing, but it serves several different purposes. Air is funneled through the filter before it is sent through the furnace and out into your home. Filters are created of tightly woven materials that grab hold of any contaminant and particle as it passes through the system, which means those contaminants are saved from entering the inside of your furnace as well as the inside of your home. If the filter is clogged, it can cause problems with:

  • Higher-than-usual heating bills
  • Lowered air quality
  • Your furnace operating internally at a higher temperature
  • More instances of repairs

Your furnace filter should be replaced when it’s visibly soiled or when you’re getting an alert on the thermostat that the filter should be changed. Locate the filter on your unit and replace it with the proper size to fit your furnace.

What You Should Know About Running Your Furnace Without a Filter

If something happens and you have to pull your filter out for the day or even a day or two, it’s probably not going to cause major problems right away. However, it’s never a good idea to leave the filter out of your furnace for any longer than that. Doing so will quickly cause the indoor air quality in the house to deteriorate. Plus, your furnace could collect enough dust and contaminants that it leads to repair and maintenance.
