Many people believe that there is only one purpose of a furnace filter or an air conditioning filter. And that is, to reduce dust is in the home. This may be a very important job for your furnace filter to take on but it’s not the only function your furnace filter has. The filter actually has another extremely important function that very few people are aware of. The other function that furnace filters are responsible for is not quite as apparent unless you are mechanically inclined or perhaps work in the HVAC field.



Furnace filters reduce how much dust is being collected on the machinery within the furnace. There are a number of primary components that need to run smoothly and effectively in order to make your furnace as effective as it can be. If dust should collect on these components, it can significantly reduce how efficient your furnace is, which will cause heating problems and other risks that need to be avoided.

Any dust that passes through your furnace filters rather than being caught will eventually be returned to your living space. This can pose problems to a person who suffers from allergies, as well as anyone else who has sensitivity to airborne pollutants and dust. What many people do not realize is that there are other important purposes that furnace filters serve in addition to simply catching these airborne pollutants and contaminants to keep them out of the air in your living space.

Not only are furnace filters designed to collect dust and other airborne particles to clear up the quality of your in-home oxygen, but they are also increase airflow properties within the furnace. If the airflow in the furnace is weak, it may overheat, which can cause problems over time. Nothing good comes from having poor airflow within your furnace because the airflow inside your furnace is directly responsible for keeping all of the parts in working order. By keeping the furnace cool, you can guarantee that parts will not overheat and cause problems.

In your furnace there is a piece of equipment known as a heat exchanger that is a vital element in keeping your furnace running properly. If the airflow in your furnace is restricted because your furnace filter is clogged, your furnace can overheat because the heat exchanger is pressed right up against the igniter in your furnace. If your heat exchanger is forced to heat up and cool down too often, it can warp and eventually crack. Broken heat exchangers can cause fires and carbon monoxide leaks.

So while one primary purpose of your furnace filter is to clean up the air in your home, it is by far not the only purpose that is serves. Your furnace filter is also responsible for promoting the efficiency of airflow within your furnace keeping your furnace running safely and effectively.

If your furnace filter is running effectively then you will likely not have to worry about safety issues or potential risks. Read about furnace filters and how to protect you and your family from indoor allergies at .

Not only will an efficient furnace filter keep your air clean and breathable by removing dust, pollen and other allergens from the air but also keep your furnace operating at its peak efficiency at all times.
