If you’re thinking about purchasing a dehumidifier or you already own one, it's highly likely that you've wondered, "does a dehumidifier kill mold?"
To be honest, it’s a fundamental question. Mold and mildew are some of the most common problems that irritate homeowners. Mold can end up causing a ton of respiratory issues, especially for children, and it’s tiresome to treat.
The worse thing about mold is that once you treat it somewhere, it emerges somewhere else, putting you in an endless cycle of mold treatment.
That said, today, we’ll speak about the role of dehumidifiers in dealing with mold and how they can be of help when it comes to taking humidity down a few notches.
Can Dehumidifiers Kill Mold?
The short and straightforward answer to this question is no, dehumidifiers can’t kill mold. Nevertheless, they can have a notable effect on mold, and they do play a critical role in the growth of mold and whether it advances to other parts of your house or it stays dormant where it is.
Dehumidifiers have a bunch of other health benefits that can significantly improve your quality of life through the use of inbuilt air purifiers for mold. Also, as they keep the humidity levels within the normal range between 30% and 50%, they improve your breathing and help eliminate a lot of common health issues.
How Can a Dehumidifier Help With Mold?
So, what does a dehumidifier do with regard to mold? To answer that question, we first have to explain what a dehumidifier does in general.
Essentially, a dehumidifier works on removing the moisture from the air and collecting it in a tank or disposing of it directly through a hose and a floor drain.
The moisture in the air is known as the level of humidity, and if it goes up above the average level, it can cause a lot of problems with both the respiratory system and the digestive system.
Moreover, humidity promotes the growth of mold and mildew as it provides the perfect environment for them to thrive. Mold particles can come to your house from all kinds of places, even through the ventilation systems and windows. They find somewhere that is dark and humid to dwell and multiply. Warmness, darkness, and moisture are the perfect conditions for mold growth.
As indoor humidity goes up, mold spores grow and multiply even more and expand in your house. Hence, you might find mold in bathrooms, kitchens, and basements, places that generally have very little ventilation.
What does a dehumidifier do in this case? It reduces humidity by sucking the excess moisture from the air, making the atmosphere too dry for mold to multiply. Consequently, it stunts the growth of mold by preventing it from multiplying. Yet, it doesn’t kill the originally present mold particles.
To kill mold particles, you have to hire professional help from a reputable mold removal company and, of course, investigate the main reason behind the mold issue.
Sources of Mold
As we have just said, particles of mold can come from anywhere. For instance, mold has a tendency to stick to the coats of pets. So, if you have a dog, there's a chance that the mold in your house made its way there through your dog's fur.
Nonetheless, there are some known sources and signs for mold that you need to look out for in your house. If you find that a wall of yours is forming condensed particles of water, or is suffering from water stains, then you need to investigate that because it could be hiding a leak behind it.
Internal piping systems are one of the major reasons for mold infestations in general. If you’re faced with any spot that has a musty odor, feels wet, smells like dust, or is changing in color, such as black mold or any type of visible mold, then an investigation would be wise at this point.
As a homeowner or a tenant, inspections of moisture sources and condensation on a regular basis can save you a lot of trouble as mold infestations can get incredibly traumatic as they grow and expensive to treat as they find their way into other parts of your house stealthily.
To sum up, no, a dehumidifier can’t kill the originally present mold. Still, as it brings the humidity levels down, it forbids it from multiplying and increasing in number. Thus, it limits the problem and helps you only deal with so much less than what you would have had to deal with if it weren’t for dehumidifiers.
