Controlling mold is another reason apart from comfort and avoiding allergies that people give when searching for dehumidifiers. In theory, all dehumidifiers can eliminate mold growth by maintaining humidity levels just below the 50% RH mark. However, when the weather conditions outside are extreme and favor high levels of humidity, your dehumidifier can only do so much, and may not work as perfect as required. We therefore think that you’ll need a unit that is more powerful and effective. We also recommend going for a unit that has an auto-restart feature built in them. This will work perfectly especially when you have frequent power outages—it saves you the time of having to press a button every now and then. If your problem inclines more towards the industrial need, you can check out our review on some of the best industrial dehumidifiers here.
