Water purifiers for the Institute allow businesses like offices, schools, hotels, restaurants, and cafes to serve their patrons and staff with high-quality water. It is possible to install an Pristina Green Eco RO-II at any business where there are 50–75 employees or patrons. By avoiding purchasing water bottles for drinking, you can also save money. The institute’s water purifier, the Pristina Green RO-II, has a 50 lph purifying capacity. By delivering 50% of the product water, it conserves water. These commercial RO systems have affordable operating and maintenance costs and dramatically lower energy use.
