Can a Dehumidifier get Rid of Mold?

Mold is a common cause of health ailments, and it can quickly take over your home. If mold is left untreated, it will multiply and spread. To stop this from happening, the mold must be destroyed. Depending on the extent and location of the mold problem, there are one or more ways to solve it.

Mold

Mold is a fungus that thrives on moisture and warmth. To spread, mold puts spores into the air, which you can inhale if you’re in range. For people who have asthma or mold allergies, spores are particularly dangerous.

When the spores land in a spot conducive to their growth, they feed on that surface, which leads to two problems. First, the mold will continue to grow because it has a food source. Second, the surface on which it eats breaks down in the process.

Mold Sources

Wherever there is moisture; mold is often nearby. The kitchen and the bathroom are two places where mold is commonly found. These rooms are where most of a home’s plumbing is located. Plus, the steam produced by cooking and showering raise the humidity level.

Areas around doors and windows are two more places that mold tends to grow. Due to gaps and cracks that occur with time, mold can easily find its way indoors. The likelihood of this occurring gets higher after a heavy rainfall. Then, there are basements and roofs. These structural components are also common entry points for mold.

Dehumidifier and Mold?

The Role of a Dehumidifier in Mold Eradication

Dehumidifiers offer several benefits, but they cannot kill mold. What a dehumidifier can do is control the growth of mold. How? Once the dehumidifier lowers the relative humidity in a room, the mold stops spreading. Instead of dying, the mold stays dormant.

As long as the humidity level stays within a 30 to 60 percent range, the mold won’t grow, but it also won’t go away. After you hinder mold from growing, you can take the proper steps to get rid of it for good.

How To Remove Mold

Bleach, peroxide, and vinegar are three viable cleaning solutions to use for mold removal. If you use bleach or peroxide, you must dilute it with water. If you opt for vinegar, you can use the vinegar without diluting it. With whichever solution you choose, let it sit for about 20 minutes. Then, use straight water to rinse the area and allow the spot dry.

While this method takes care of mold on surfaces, it does not kill the mold spores in the air. If you have an existing mold problem, invest in an air purifier. With an air purifier running in the background, you get rid of the mold spores in a few weeks’ time.

What humidity is needed for mold to grow?

Cleaning a Dehumidifier

Since the purpose of a dehumidifier is to extract and collect moisture, the appliance can quickly become a haven for mold. Therefore, proper dehumidifier maintenance is a must. To start, always empty the water in the reservoir as soon as it’s full or use your dehumidifier’s drain port if it has one.

If you see mold growing in the reservoir, you can get rid of it rather quickly. Simply follow the cleaning directions provided in the user manual. If you can’t find your manual, you can take a half-cup of bleach to a full gallon of water to clean the reservoir followed by a water-only rinse and a thorough wipe down to dry it.

Preventing Mold Growth

Running your dehumidifier with the air is humid is one of the best ways to stop mold growth before it starts. Also, turn on your air conditioner to cool your home on hot days, and look for pooled water around your house, such as the bathtub after showering and the sink after washing dishes.

How long do you need to run a dehumidifier?

Repairing mold entry points also prevents mold growth. Check the insulation around your home’s pipes and doors. Patch up your leaky roof and be on the lookout for HVAC and window condensation. Don’t forget to conduct a thorough check indoors and outdoors after a flood or major storm.
