In the winter, humidifiers provide comfort throughout the home by using central heating and cooling systems to prevent indoor air from becoming too dry and uncomfortable. The HE105C Whole House Bypass Humidifier offers the same level of quality as Honeywell humidifiers, but at a more competitive price. It's an easy way to expand Honeywell's offerings and profit from them as well. Optimized humidity levels in the home eliminate the irritants associated with dry air, including the risk of respiratory infections. With its universal design and easy-to-use pad, this humidifier helps manage indoor humidity levels and creates a pleasant environment.
