What Causes a Furnace Filter to go Black?

Your home’s heating and cooling system filters have a crucial task to complete. They remove dust, pollen, and other small particles from the air you and your family breathe. To stop these particles from being circulated throughout your home again, the filter traps them.

Over time, the filter becomes full, and if not replaced, it can cause your heating system to work less efficiently. Not only that, a filter puts unnecessary stress on your system, which can lead to it breaking down. So, call the professionals at Agape Air Heating & Cooling for timely heating service in Gilbert, Arizona, and surrounding areas.

Your furnace may be having issues if your filter is black. The reasons for a black furnace filter are as follows:

The Furnace Filter Is Jammed And Not Effectively Removing Dirt

If your furnace filter is black and you are confident that mold, soot, or carbon monoxide is not the cause, the filter itself may be clogged and accumulating dirt that comes into touch with it. Filth will enter the furnace through a clogged air filter, endangering the furnace’s ability to function properly.

Furnace Filter Is Gathering Carbon Monoxide From Home Emitters

The most frequent reason for a black furnace filter is deadly, colorless, and odorless carbon monoxide gas. While the purpose of your furnace filter is to screen out dirt from other furnace equipment, it can cause the dirt to become lodged on the filter. Both the filter’s and the furnace’s functionality are affected, resulting in an all-black filter that provides the lowest amount of effectiveness in this situation.

Obstructed Vents Impeding Airflow

Blocked vents result in improper combustion at the furnace, which may result in leaks or black emissions that land on your filter. Obstruction or leaks in the venting system can cause a furnace filter to turn black.

Formation Of Mold In Furnace

When it comes to your furnace, there are several reasons that might produce moist habitats for mold growth. One such circumstance is condensation from an air conditioner running, which results in a damp evaporator coil. If this condensation isn’t responded to, it eventually combines with dirt and dust to create black mold and will probably migrate to your furnace filter.

Clogged Furnace Filter Not Removing Dirt

If you have a clogged furnace filter, it will not be able to remove dirt effectively. As a result, the dirt will accumulate on the filter and eventually turn black.
