Filter Pure features drinking water purification systems, whole house and light industrial units, lamps, quartz sleeves, replacement filter cartridges and parts from Pura©.Ultraviolet is a safe, clean, easy-to-maintain method of assuring that water is free of bacteria. It is a proven technology. In some applications, its initial cost is a bit more than chlorination, but because of its low operating cost, it quickly pays for itself. It is environmentally friendly and is essentially trouble-free. Most ultraviolet water treatment systems require only an annual change of lamp—as simple as changing a light bulb—and a periodic change of filter cartridges if the unit has accompanying filters. Not sure if UV is the right application for you, call our Customer Service Team at 1-800-942-7873 for assistance.
