Enjoy fresh, great tasting pH+ mineral water right at home that is perfect for drinking, cooking and making delicious coffee, tea and ice. RO-PH90 guaranteed to remove up to 99% of harmful water contaminants such as chlorine, taste, odor, VOCs, as well as toxic fluoride, arsenic, lead, nitrates, heavy metals, and much more. Save money, time, and hassle from buying costly bottled water, and live healthier with alkalized, calcium mineral drinking water. APEC Top Tier RO-PH90's mineral cartridge adds only 100% US-made high-purity calcium carbonate to effectively raise pH in the water for those who desire alkaline water.
