Whole House

The Pura UV20 Series and Pura UVBB “Big Boy” Series consist of single, double and triple units built to deliver clean, bacteria-free water to the whole home. In addition to lamp-only single housing units, double units are available combining ultraviolet purification with sediment filtration (recommended for well water), and triple units that add a high quality carbon block for chemical reduction and taste / odor improvement.

UV20 units are capable of treating water at flow rates up to 10 gallons per minute — ideal for most single-family residential applications. Standard port size is 3/4". Double and triple housing units use standard-sized 2.5" X 20" filter cartridges.

UVBB “Big Boy” units are capable of treating water at flow rates of up to 15 gallons per minute. Standard port size is 1.5". These heavy duty units offer greater filtration capacity and higher flow rates; double and triple housing units feature jumbo-sized 4.5" X 20" cartridges.
