Humidifiers create a soothing atmosphere in your home. According to the Mayo Clinic, indoor humidity between 30% to 50% is ideal 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 Warm and Cool 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. The humidifier runs up to 100 hours on the low setting and 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. Easy-to-use electronic controls for setting timer mode (12-hour timer), plus adjusting LED lighting, mist options, and humidistat. Features patented safety fuse technology. Comes fully assembled.
