Why Your Furnace Has a Filter

You always hear about how important the air filter is for operating your furnace. You need to change it regularly, make sure it fits, and find one of good quality. But have you ever stopped to ask why?

Why is the filter so crucial for your furnace? We’re breaking it down so you can run your furnace for years to come at peak efficiency.

It’s Actually for Your Furnace

Many people are under the impression that the air filter is for the air you breathe when in reality, the filter is more for your furnace than it is for you. A filter protects the complex system within your furnace from being subjected to dust, debris, and particle buildup.

Your furnace brings in air from the environment, which it then treats and pushes back into your home as the warm air you crave in the winter months. As your furnace pulls in air, it can be loaded with dust, pollen, air pollutants, and other contaminants that will then stick to the components of your unit. Over time, this buildup can cause parts of your furnace to fail, and overall cause your system to wear out faster.

A filter protects your system, keeps it clean, and allows it to run more efficiently, as long as you remember to keep the filter clean, of course.

Help for Indoor Air

Improved indoor air quality is a secondary benefit of the furnace filter. While it won’t significantly impact your indoor air quality, it will have an effect, especially if the filter isn’t changed out regularly. Those particles that would have entered your furnace will settle, but any that don’t, will make their way throughout your home, impacting the air you breathe.
