Sleek and stylish, the home soda maker is a countertop appliance about the size of a coffeemaker that transforms water into fresh, fizzy seltzer/sparkling water at the push of a button. Soda makers operate without batteries, electricity or plumbing, so they are simple to use in a kitchen and great for bringing along on a boat, RV or to a second home. Making seltzer and soda takes just seconds and requires no clean-up.A reusable, one-liter carbonating bottle (provided by Soda-Club) is filled with water and screwed into the machine fitting. A CO2 carbonator, housed inside the soda maker, adds carbonation at the touch of a button as much or as little as the consumer prefers. After carbonating the water, the soda drinker simply adds a capful from one of over 25 sodamix flavors to make his or her favorite, great-tasting soda.
