A Musty Basement Isn't Just an Odor Issue

A lot of people think that the musty scent of a basement is par for the course. Isn’t having a space that’s underground going to smell no matter what? The answer is actually no. Sure, basements are prone to higher humidity which means that it’s easier for mold and mildew to spore since moisture enables them to thrive. So that basement smell is actually mold, which, in addition to having a funky odor, can also cause decay and damage to a home over time. For people who suffer from asthma and other respiratory issues, the problem can be even more serious. 

The ideal humidity level for most homes is 50% or lower, but in basements, humidity can often skyrocket to 80%, which is the perfect environment for mold and mildew to flourish. If your basement seems extra damp, I highly suggest investing in a dehumidifier that will work to draw the moisture out of the air. You’ll be shocked at how quickly the holding tank on an average-sized unit fills. You may have to dump it daily, but in doing so you’ll be removing moisture that allows mold to grow in the first place.

Next, 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.

One of the best air dehumidification and purification units I’ve seen is by a company called Aerus.  They produce a system that uses NASA technology to remove pathogens, pollution, contaminants, and even pet dander from the air. Regardless of what brand you go with, 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 your plan of attack, 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. The symptoms of a mold allergy are not dissimilar to a common cold, so a simple reading of your in-home humidity might be a smart first step.
