The sleek design with a brushed stainless steel surface fits into almost any kitchen or living style. The sparkling water maker does not require an electrical connection. This means fresh sparkling water anytime and anywhere, up to 60 liters of delicious sparkling water, with just one CO₂ cartridge. At the same time, you save the environment from about 120 single-use plastic bottles. When the sparkling water maker is in operation, the safety valve automatically releases the pressure in the bottle; the humming sound indicates that the sparkling water is ready for you. Fill, twist, and press; adjust the intensity of the sparkling water to your personal preferences. The more you press, the higher the carbonation level and the sparkling sensation. A BPA-free 1-liter bottle and a CO₂ cartridge for up to 60 liters of sparkling water are included.
