The new RESDELUX electrode steam humidifier is designed for home or condo use. The unit employs state-of-the-art electronic technology to deliver up to 8 pounds/hour (23 gallons per day) of steam humidification, the company says. Set the relative humidity level and an integrated electronic controller automatically maintains the level selected. Impurities, sludge, scale, and minerals in the water supply are deposited into the unit's disposable plastic cylinder. A light indicates when the cylinder needs replacement.
