HOmeLabs makes yet another appearance, with the smaller, less powerful iteration of their Energy Star Dehumidifier, the hOmeLabs 1,500 Sq. Ft Energy Star Dehumidifier for Medium to Large Rooms and Basements. With a sizable one gallon capacity, this high-performing dehumidifier works perfectly in spaces with an area of up to 1,500 square feet. Considering it’s a bit smaller and lighter than the first one on our list, it could be a better option for smaller RV units — or smaller spaces, in general. This unit is one of the best dehumidifiers explicitly crafted for people with somewhat limited space. Well, not necessarily limited, but it’s certainly not powerful enough to dehumidify your entire home, but it’s perfect for any room, thus making it a more-than-acceptable model for almost any RV. This device also features a powerful Turbo mode that increases fan speed from Normal Air CFM 129 (cubic feet per minute) to High Air CFM 138, which removes moisture and odor swiftly and quietly. For all intents and purposes, this is one of the best options for your RV, period.
