Why Are My Air Conditioner Filters Turning Black

You already understand the importance of changing your air filters regularly. And you’ve been doing just that! But despite your efforts, you still have a black air filter.  A clean air filter removes dust, dirt and other debris from your home. So needless to say, it’s a key component of your AC system.

3 Reasons Why Your Air Conditioner Filters Are Turning Black

So, why are your air conditioner filters turning black?

1. Mold

Unfortunately, homes in humid areas are mold prone. In Florida, air conditioning systems can provide the perfect habitat for mold growth.

When your air conditioning system runs, condensation collects on the evaporator coil. Sometimes this moisture transfers to the air filters.

And if it does, viola! You get air filter black mold.

As soon as you notice air filter black mold, dispose of the filters!

Mold can make you and your family very ill. Symptoms of sickness from mold can include a sore throat, stuffy nose, coughing, wheezing and eye irritation.

Immediately replace the moldy filters with fresh air filters and schedule an appointment with your local HVAC technician.

2. Soot

Fragranced candles can really add a relaxing flair to your home. But they can also be the culprit for black soot on your air filters.

Soot is a byproduct of burning candles.

The accumulation of excess soot from candles can decrease the efficiency of your air filters.

But don’t worry candle lovers! You don’t have to lose the ambience candles bring to your home.

All you have to do is cut the candle wicks to one-quarter inch before lighting them. Doing this will prevent your candles from leaving black soot on the air filters. You can also try all-natural candles made from soy, which will help reduce soot.

3. Clogged Air Filters

Maybe neither mold nor soot that are to blame. If that’s the case, you’re probably dealing with a clogged air filter.

A black air filter may be clogged, resulting in restricted airflow to your home. This is bad for your home’s indoor air quality and makes your air conditioning system work harder to cool your home. To prevent clogging, we recommend changing your air filters once a month.
