Without air conditioning, a dehumidifier can help curb summertime discomfort. But what about six months from now when you want the opposite - a humidifier for dry winter air? This home comfort unit both dehumidifies and humidifies. Plus, it functions as a HEPA air purifier, too... When functioning as a dehumidifier, the unit can handle 60 pints. It takes 20 pints of water at a time as a humidifier. We're happy to see this product, as the fewer devices we have sitting around the house, the better. The three-in-one device sells for $349 at Amazon.
