It also adds calcium, magnesium, and potassium minerals and anti-oxidants, and provides a low negative ORP between -100 and -200 mv. GREAT VALUE: One Alkadrops Stream filter can replace up to 300 16.9 oz bottles of water, so you can enjoy great-tasting filtered water at a fraction of the price and waste of bottled water.
