Enjoy dual relief from congestion and cold and flu symptoms with the Steam Inhaler and Warm Mist Humidifier. The Inhaler provides personal treatment for congestion, dry cough, and stuffy noses while the Warm Mist Humidifier offers comfort and long-term benefits from using year round. While using as a Warm Mist Humidifier, the Crane Two-In-One uses a half gallon tank and will run for up to 13 hours. The nebulizer heats the water to produce steam that comes out through the mist lid. When using as an Inhaler, the Crane Two-In-One automatically shuts off after 20 minutes indicating a full treatment cycle. The moisture that humidifiers add to dry air also help alleviate many common nuisances brought on by winter heating such as static electricity, peeling wallpaper, shrinking wood, and cracks in paint and furniture. All Natural, Non-Medicated Relief from Dryness, Cough, Cold, and Flu Symptoms Humidifiers are an ideal choice for relieving the discomforts of nasal congestion, dry itchy skin and hair, chapped lips, nose bleeds, and dry throats. Easy Cleaning and Use Crane's Two-in-One comes with one base and two interchangeable top pieces, the inhaler vent and water tank, which separate from the base to allow for easy cleaning. In between uses, leave the cap off of the water tank so it can air dry. This weekly maintenance will ensure your Crane Two-In-One lasts for many seasons to come. 1 Year Manufacturer's
