UV Treatment - Class A or Class B? What's the Difference?

NSF/ANSI 55 separates UV water purification systems into two distinct classes. 

Class A UV water systems should be used with well or surface water (streams, lakes, etc.) and are designed to inactivate and/or remove microorganisms, including bacteria, viruses,  Cryptosporidium oocysts and Giardia cysts from contaminated water. 

​Class A UV systems are not intended for the treatment of water with an obvious contamination or intentional source, such as raw sewage, nor are they intended to convert wastewater to drinking water. They are intended to be installed on visually clear (not colored, cloudy or turbid) water. 

Class B UV water systems, on the other hand, should be used with municipal water or treated water and are designed for supplemental bactericidal treatment of disinfected public drinking water, or other drinking water that has been tested and deemed acceptable for human consumption by the state or local health agency having jurisdiction. 

Class B UV systems are designed to reduce normally occurring, nonpathogenic nuisance microorganisms only. These systems are not intended for the disinfection of microbiologically unsafe water and may not make individual or general cyst claims. Microbiological health effects claims may not be made on Class B systems.
