Why Is My A/C Filter Turning Black?October 20, 2016 4:07 pm Leave your thoughts
What’s Black Soot Deposition?
Black Soot Deposition refers to the household problem marked by black stains on walls, carpet, furnishings and yes, air filters.
What causes these black stains?
Burning candles in your home. Or more specifically, burning scented candles in your home.
So how does a candle turn your air filter black?
The quick answer: When candle wax burns, it produces tiny, black soot particles that deposit themselves on surfaces such as walls, furniture and carpet. The more ”impurities” (for example, scented oils) the candlewax contains, the more soot it produces.
The more technical answer: Candle wax (also called paraffin) is made from carbon-based materials. As the wax melts when it interacts with the candle flame not all of those carbon particles burn fully.
How do I prevent candle soot deposition in my home?
- Choose candles that are hard to the touch at room temperature. Soft-to-the-touch candles are a good indication that there are a number of “impurities” in the wax that will produce more soot.
- Keep your wicks short. Get in the habit of trimming your candlewicks to ¼ inch. Remember that the amount of wick exposed increases as the candle burns so you’ll need to trim repeatedly.
- When possible, buy candles that were made and manufactured in the U.S. American made candles are produced under strict guidelines that aim at reducing the amount of soot a candle produces. But foreign-made scented candles were likely manufactured under less strict guidelines and most likely contain more soot-producing materials.
- Steer clear of candles that have petroleum jelly or vegetable oil mixed into the wax. Higher percentages of either of these additives produce a large amount of soot.
- Keep your candle flame away from air movement. A candle flame disturbed by air movement produces up to 300% more soot. Avoid burning candles when the AC is blowing and try not to place them in areas where people repeatedly walk or under/near ceiling fans.
- Invest in an activated carbon filter. An activated carbon air filter purifies your home’s air with a 5-state filtration system.The last layer contains activated carbon that traps gases,fumes, tobacco smoke, toxins and chemicals produced by candle burning.
