When a furnace filter first comes out of its packaging, it is as white as the snow on the ground. Over time, however, it will eventually start to turn black. Let’s take a look at why this happens and what you can do to prevent any damage to your furnace.

The Filter Grabs Contaminants Out of the Air

An air filter’s main job is to gather dust, pollen, and other particles. As it does so, the filter will start to change color from white to black. Therefore, it is actually a good thing to find that a furnace filter is darker than it was when it was installed. However, it does mean that the filter will need to be changed in the near future.

What Happens If a Dirty Filter Isn’t Removed?

If a dirty air filter is not removed, it could make it harder for your furnace to operate at peak efficiency. It could also lead to problems with a blower motor or other furnace components. The professionals at Carson Brothers Montana in Kalispell can help with furnace repair and maintenance. We can also install a new furnace to replace an inefficient system.

How Often Should an Air Filter Be Replaced?

Ideally, an air filter will be replaced at least once every six months. However, the exact timing will depend on how much debris is in the air and other factors unique to your home. In some cases, it may be necessary to change a filter every 90 days. Our technicians may be able to inspect or replace an air filter during a service call.
