The Dangerous Reason You May Want To Avoid Using Portable Dehumidifiers

If you have a portable dehumidifier in your home, you may want to consider replacing it with a more permanent solution. Despite the usefulness of this appliance, it can actually prove to be more of a danger than an aid to your home. Dehumidifiers are utilized as a way to reduce the moisture level in your house, which can help with allergies, mold growth, and overall air quality. Since dust mites require a significant amount of humidity to survive, you can get rid of dust mites in your home with the use of a dehumidifier, too. Many homeowners opt for a portable unit, as they are less expensive and easier to install than a whole-house version. However, portable dehumidifiers have been linked to numerous house fires, to the extent that many brands have initiated a massive recall of these items. 

Over the past few years, there have been multiple reports of portable dehumidifiers overheating or even catching fire. According to Consumer Reports, there have been more than 400 fires, causing millions of dollars in damage, and at least four deaths from house fires due to portable dehumidifier malfunctions. Just a few weeks into 2026, WBAY Action 2 News reported a blaze in Wisconsin was caused by a "faulty dehumidifier," which sparked a fire in the basement. Whether you own a portable dehumidifier or you were considering purchasing one for your home, you may want to opt for a whole-house dehumidifier instead. 

With all the benefits to these devices, a fatal fire is definitely a potential downside to using a dehumidifier that no one thinks of. The problem mainly occurs due to poor electrical components. The wiring and mechanics short circuit and spark flames. These devices can also easily overheat when used for long periods.

Multiple models of portable dehumidifiers have been recalled for their fire risk, including ones from the brands Kenmore, GE, SoleusAir, Norpole, and Seabreeze. You can check the U.S. Consumer Product Safety Commission (CPSC) website for a full list of recalled dehumidifiers. If you have a defective model, it's critical to unplug it and stop further use.

If you're someone who struggles with allergies, dust mites, and overall poor indoor air quality, you may be considering getting a dehumidifier to help with these issues. However, it's best to opt for a whole-house version instead of a portable unit. It may initially be more expensive and require professional installation, but overall, these units are the safer option, and you'll avoid hidden fire hazards in your house.
