Top 3 Reasons Your AC Air Filters Are Turning Black
Blogger The air filters within your air conditioning system have a big job to do. Not only are the air filters responsible for keeping debris from infiltrating the rooms of your home, but the air filters either extend or decrease the lifespan of your air conditioning system.
So if you notice your air filters are black every time you change them, you’re probably concerned about it.
It’s natural for dust to build up on the air filters. Even a thick layer of dust is relatively harmless, but what about black debris? What causes it? Is it normal? What can I do to stop it?
We’re answering all of those questions and more here.
Why is My AC Air Filter Turning Black?
A few things can cause your air filters to turn black or darker than normal. The three biggest culprits are mold, soot, and excess debris. Here’s more:
1. Black Mold Growth
You don’t need us to tell you that mold growth in your home is bad. Unfortunately, mold loves humid environments and Florida just happens to be one of the wettest states.
Air conditioning systems develop mold as condensation collects on the evaporator coil.
While the evaporation should drain to the outside of your system, sometimes the moisture transfers to the air filter and black mold can begin to grow.
Have you noticed black mold on your air filters? If so, it’s important you dispose of them right away and replace them with clean air filters.
We also recommend scheduling an appointment with your local HVAC technician for an inspection since mold exposure can be dangerous.
2. Soot From Candles or Incense
Do we have any candle or incense lovers reading this? If so, these products could be turning your air filters black from soot.
Soot is a byproduct of burning candles and incense. Although burning candles or incense is for the most part harmless, the buildup of excess soot from these products can make your air filter less efficient.
This means your air filter won’t be able to effectively remove debris from your home.
You can prevent candle soot from turning your AC filters black by trimming your candle wicks to one-quarter inch. Opting for all-natural candles made from soy can also reduce soot.
As for incense, we recommend limiting how much you burn in your home.
3. Excess Debris in the AC Air Filter
If your air filters aren’t being plagued by black mold or soot, the air filters might just be extremely clogged.
If you haven’t changed your air filters in a long time, be sure to do so each month.
Not changing the air filters can restrict airflow, which decreases your home’s indoor air quality and puts excess strain on your air conditioning system.
However, if you keep noticing excessive debris, call your local HVAC technician.
