3 Reasons Your Home's Air Filter is Turning Black

As a homeowner, it can be shocking to find a black air filter. But it’s more shocking to discover your filter turning black again after replacing your air filter.

If your air filter is turning black, it’s likely due to one or more of three reasons. Read on to learn what these reasons are and what you should do about them.

1. Black Soot Deposition

Black soot deposition is a phenomenon that affects many homeowners throughout the nation.

This soot is the result of burning various items, including:

• Candles
• Wood
• Oil
• Gasoline
• Cooking oil
• Carpet fibers

Basically, anything that burns can produce black soot. More commonly, though, black soot is a result of poor candle quality. When these candles burn, they produce black soot, which is sucked into your HVAC system. As a result, it turns the filter black.

2. Mold Growth

Unfortunately, mold growth is another big reason your air filter might be turning black. Mold growth can occur if your HVAC system has been damaged, if your indoor air is too humid, or if you haven’t cleaned your HVAC system in some time.

If you suspect you have mold growing in your HVAC system or ducts, you should call for professional help immediately, as too much mold can lead to respiratory issues.

3. Clogged Air Filters/Excess Debris in the AC Air Filter

If your air filters are too clogged or if there is excess debris in your AC air filter, it can eventually cause your filter to turn black. This condition is relatively normal — homeowners must change out their air filters once every six months to keep their filters clean.

Steps to Take

If you notice a black air filter, change your filter immediately. Then, vacuum around the area to remove extra dirt. If the problem persists, you will need to call a professional to change your air filters.
