Humidifiers create a soothing atmosphere in your home. According to the Mayo Clinic, indoor humidity is best between 30% to 50% and can help soothe common 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. Use warm mist in winter months and cool mist year-round. The Quiet Ultrasonic Digital Cool and Warm Mist Humidifier from Lasko creates soothing humidity for your room. Aim the mist nozzle where you need it most and choose from 3 mist flow options so you can customize the humidity for your room. The large, removable tank is easy to refill at sink or tub.
