Presenting the KENT Supreme Mineral RO™ Smart RO Water Purifier. It uses futuristic and
state-of-the-art technology to provide purer and healthier drinking water.
At the heart of the KENT Supreme Mineral RO™ Water Purifier is a Reverse Osmosis membrane
having capillaries as small as 0.0001 microns, which reduce dissolved impurities (salts and heavy
metals) and convert hard water to sweet and pure drinking water. With a patented mineral retention
system, the KENT Supreme Mineral RO™ Water Purifier allows the user to control the Total Dissolved
Solids (TDS) level in the purified water.
