Take Care of Musty Basement Smells for a Healthy Home

A lot of people think that the musty smell in their basement is a common problem that goes hand in hand with having underground space in your home. Sure, basements are prone to high humidity which, when combined with darkness, can become a breeding ground for mold and mildew. The smell that those mold spores emit can get into your clothes, furniture, storage, and your HVAC unit. If the problem does reach your air ducts and begins to infiltrate the rest of the house, that’s when you have a real issue on your hands. Before you get to that point, it’s a great idea to quite literally clear the air with a dehumidification and purification strategy. 

One of the best air quality units I’ve seen is by a company called Aerus.  They produce a system which uses NASA technology to remove pathogens, pollution, contaminants, and even pet dander from the air. It can work within an hour and is a great solution to get rid of that nasty mold smell. But without a solution to contain the humidity, the odor and the mold will keep coming back.

At this point, it’s time to reduce the moisture in the basement. Most homes want to keep a humidity level of 50% or lower, but in basements, the average humidity can often be higher than 80%, which is when mold and mildew can flourish. A dehumidification system will work to draw the moisture out of the air and into a holding tank, which often has to be dumped down a drain as often as daily depending on how quickly it gets filled. By removing the water from the air, you’re removing the odor-causing moisture and bacteria that allow mold to grow in the first place.

Finally, it’s time to purify the air. Overly humid areas attract a lot of bacteria, which is what causes the smell in the first place. That bacteria can live in walls and spread into your fabrics, furniture, and storage. By killing the bacteria in the air, you will remove contaminants that not only stink, but can also cause or irritate allergies, asthma, and immune system disorders.

When shopping for a basement air control system, be sure to look for a unit that has the EnergyStar seal, and make sure that you pay attention to the capacity of the air filtration as it pertains to your room size. If you have a big space with a lot of moisture, you might want to consider a unit that has a self-draining system to save your back and your patience.

Regardless of what kind of system you use, the air quality in your home should be taken seriously. If your kids are coughing or have allergies and you find yourself having difficulty breathing at home, it might be worth a call to your local contractor for an air quality inspection.
