Brus sparkling water maker. It saves the environment from large amounts of unnecessary plastic: Søren Refsgaard has developed a sleek and elegant device for the Danish brand Stelton that should not be missing in either the office or at home today. The carbon dioxide cartridge (CO₂ cylinder) is hidden in the slender column, and the amount of carbon dioxide released can be intuitively adjusted by turning the button on top clockwise. However, the carbon dioxide supply should only be opened when the included bottle is screwed onto the device's closure. After carbonation and before removing the bottle, the supply must be closed by turning the button counterclockwise. Simple to operate, the attractive Brus sparkling water maker from Stelton will be the best friend for anyone who loves sparkling water, whether plain or flavored.
