The unit is self-contained, requires no maintenance, and does not have any filters or buckets to empty. It's the ideal answer for mold, high humidity, foul odors, and other issues with indoor air quality that tenants have complained about. Plus, because it only uses 34 Watts, you won't have to worry about excessive energy costs. When you install this energy-efficient, automated, slim-profile, and quiet digital unit, it comes with our unique smart technology, which adjusts the output based on variations in humidity, temperature, and dew point.
