Can An Air Filtration System Remove Mold From a Home?
Air filtration systems often make many claims. Some assert that they can remove mold from a room, but is it true? The answer is both yes and no. Here’s what you need to know before you purchase one.
What Is Mold?
Mold is a type of fungi. Mold spores are in all the air that you breathe and in general, are entirely harmless. This includes inside air, which typically contains hundreds of mold spores per cubic meter.
The problem isn’t the spores, it’s what they need to survive that can become an issue. Black mold needs three things to thrive:
- A food source
- A water source
- A restricted airflow.
Why Is Mold Bad?
Black mold rarely finds a hospitable environment outdoors. But homes are filled with its favorite food: cellulose. Wood, drywall and paper are a feast to it. It also grows on textiles, such as carpets and couches. Plus, once established, it tends to spread everywhere. It also eats away at the materials your home is made of and emits a disgusting odor that can fill a home.
Can an Air Filtration System Eliminate Mold?
While they can’t actually remove established mold, an air purifier with a certified HEPA air filter can reduce mold spores in the air. Nothing short of expensive, laboratory-grade filtration will eliminate spores, but a HEPA filter is the gold standard for home air purification and most experts recommend getting one.
How Can You Get Rid of Established Mold?
Black mold is extremely tenacious once it settles in. It requires sophisticated techniques, disinfectants and equipment that only the top local mold restoration experts have access to. The impacted area must be contained to prevent further spread, and the source of the excess moisture will be identified and corrected. Indoor mold always indicates a problem with moisture intrusion.
Mold cleanup includes cleaning the contents of your home. In most cases, it’s cheaper to replace heavily mold-damaged items, but if they are valuable or sentimental, they can often be saved by experts.
Air filtration is one way to reduce the number of spores in your indoor air. However, it’s not going to be effective at eliminating established mold.
