Reverse Osmosis Alkaline Ionized Water Filter. Why buy an expensive Water Ionizer? Aptera Alkamag Alkaline Water filters are used with a Reverse Osmosis (RO) System to eliminate contaminants like chlorine, fluoride, lead, and viruses; while the Aptera filter increases the pH of your drinking water and lowers the ORP. The Aptera alkaline ionized water filter also does not require any electricity and produces alkaline water with longer lasting effects, as opposed to electronic water ionizers unstable alkaline water which dissipates within 24 hours.
