Enjoy the air you breathe. A properly humidified home can help you breathe more comfortably with less dryness, save on energy costs, reduce static electricity, and even help protect your wood furniture. The Performance bypass humidifier uses less electricity than fan-powered humidifiers by letting your furnace blower supply the air movement to drive moisture vapor into your ducts. This humidifier was engineered to work with Carrier products for improved whole-home comfort.
