The PURA UV ADDON Series is an easy addition to existing water treatment systems that require ultraviolet disinfection (RO systems, holding tanks, water dispensers, recirculation systems, etc). The ADDON systems are available with a 1 GPM or 3 GPM flow rate. They are constructed using a 304 grade stainless steel body with a molded head that includes 3/8” quick-connect fittings on the inlet and outlet. The Add-On systems include a heavy duty mounting bracket, but will also fit standard 2” RO mounting clips. The UV ADDON series can be used almost anywhere and is equipped with a low-profile power supply that makes installation simple, space requirements minimal and lamp changes easy.
The PURA UV1-EPCB combines both ultraviolet disinifection with carbon filtration all in one compact system. The UV1-EPCB is a unique unit that consists of a single slimline housing that holds a UV lamp inside PURA’s exclusive extended pass 0.5 micron carbon block filter. It’s a great single-pass treatment for removal of bacteria and cysts as well as chemical contaminants. The UV1-EPCB is rated for a 1 gallon per minute flow rate.
The PURA UVB Series is designed to provide disinfected water at a flow rate of 2 gallons per minute.

The PURA UVB is a compact All-in-One system that installs with ease and can be used anywhere that clean, clear, good tasting disinfected water is needed. It is ideal for point-of-use applications like: under the kitchen sink, office water coolers, water vending machines, boats, recreational vehicles, etc.
The patented PURA UV20 Series is designed to provide disinfected water at a flow rate of 8-10 gallons per minute. This system is ideal for whole house water treatment. In addition to disinfection, the double and triple models provide filtration for the removal of sediment and chemical contaminants. These whole house ultraviolet disinfection systems are ideal for most residential applications. Port size of all vessels is 3/4", allowing for more than adequate flow rates for most homes. The UV20 series has proven to be PURA’s most popular product line and has created an industry standard in whole-house disinfection.
