DESC: Built for superior performance and low maintenance, this 3-gallon humidifier features a digital humidistat that automatically maintains desired humidity levels for room sizes up to 1600 square feet. Its adjustable two-speed fan provides whisper-quiet operation, while an exclusive NiteGlo nightlight illuminates the tank with a soft glow. The unit's Regulated Release system eliminates stagnant water around the exclusive, extra-absorbent, PermaWick paper wick filter, which never needs to be replaced and is treated to inhibit the growth of bacteria, mold, and fungi. The humidifier's airtight, watertight ToteAway tank is designed with a large refill port for easy filling, and its base and tank are dishwasher safe and easy to clean. For safety and convenience, the unit automatically shuts off when it is empty. The portable, cool-mist humidifier measures approximately 18 by 14 by 15 inches and carries a five-year limited warranty.
