Cool mist humidifiers with aromatherapy create a soothing atmosphere in your home. According to the Mayo Clinic, indoor humidity between 30 percent to 50 percent is ideal and can help soothe dry air problems of the skin, throat, and sinuses. Additionally, proper humidity levels can create an atmosphere for improved sleep and reduce static electricity from dry air. The Ultrasonic Cool Mist Humidifier from Lasko provides quiet, soothing humidity for your room. The cool mist nozzle is adjustable to 360-degrees. The removable tank holds 95 ounces of water, so it will run up to 60 hours on the low setting. The adjustable mist control knob is simple to use and allows you to customize your room humidity level. Monitor your water supply through clear tank, then easily refill at sink or tub. The humidifier will automatically shut off when the tank is empty. Regular maintenance is a breeze because there are no filters to replace, plus the included cleaning brush can be stored conveniently right on the unit. 1 year limited manufacturer warranty.
