The Beurer Steam vaporizer combines the traditional trusted inhalation therapy with an ultra-quiet, modern design.  The extremely quiet SI 40 steam vaporiser from Beurer impresses with its soothing application. Liquids such as saline solutions and essential oils can be safely vaporised by the Steam Vaporizer and colds don’t stand a chance. With the Beurer steam vaporiser the hot water is enclosed in a water heater tank which means it cannot easily spill onto your skin.  The variable steam regulator holds the vapour at a constant temperature so you can be sure of a steady stream of warm, moist air. The adjustable slider control regulates the amount of steam produced and the flexible mask which covers your mouth and nose ensures that your treatment is comfortable and personal to you.
