The air filter is a very important part of your home's HVAC system. It is responsible for preventing debris from entering your home and also helps to extend the life of your air conditioning system. But what does it mean when your air filter turns black? The air filter can become clogged, which can restrict airflow and hamper your home's indoor air quality. It can also be caused by soot, which is a by-product of burning candles or gas water heaters.
Mold is another cause of black filters, which occurs when moisture from the air conditioner condensation is transferred to the air cleaner. Mold in air filters is a health risk and can exacerbate respiratory conditions such as COPD or asthma, or cause pneumonitis, mold allergies, and other health problems. To avoid blockages, it is recommended to change air filters once a month. If you have a candle or incense lover in your home, these products could cause your air filters to turn black from soot.
Over time, if you don't change the filter as scheduled, it may turn black. If mold and soot aren't to blame, it's probably just a heavily clogged air filter. If you notice mold growth on air filters, dispose of them immediately and put them in fresh air filters. Regular maintenance and cleaning will help keep mold out of your HVAC equipment and ensure that the air filter does not turn black.
Not only are air filters responsible for preventing debris from infiltrating your home's rooms, but they also help to extend or decrease the life of your air conditioning system. Be sure to subscribe to the Filter King blog to learn more about air filters, air conditioning, and home improvement.
