RO-50S is a reverse osmosis membrane for drinking water with the perfornance up to 190 L/day or 7.8 L/hour (50 Gal/day). The membrane completely removes hardness salts from the water, providing long-lasting anti-scale protection for home appliances like coffee machine, kettle, iron or steamer. RO membrane technology rejects even the tiniest amounts of impurities in tap water making it safe to drink and cook with. In addition to common contaminants, RO membranes remove nitrates and nitrites, fluoride, bacteria, viruses, antibiotics, hormones and many other potential waterborne threats.
