The BlueAir InvisibleMist Humidifier H35i is a new evaporative model that stands out with two key features: smart controls and a dishwasher-safe water tank. When the tank runs out of water, the H35i automatically switches to a low fan speed to dry out the wick, helping prevent mold or bacteria growth. This feature makes a noticeable difference, as the air in the room feels less damp compared to other models, even when humidity levels are too high. The H35i also boasts an energy-efficient DC-powered motor, a highly functional app, and a three-year warranty.
