Trojan UV Max ultraviolet (UV) water sterilizers are designed specifically to kill harmful microorganisms such as bacteria and viruses in untreated water supplies (well water or private water systems). Ultraviolet (UV) systems are commonly installed by homeowners who have received a positive coliform, e.coli, cryptosporidium, or giardia water test result, as well as those with reason to suspect that they are at higher risk for such contamination, and those seeking to have peace-of-mind that their water is being properly disinfected prior to consumption. Ultraviolet whole house water sterilizers are exploding in popularity due to their low maintenance requirements, ease of operation, economical purchase price and operating cost, and due to the fact that unlike other treatments designed for microbiological contaminants, UV does not introduce any harmful chemicals to your water. Trojan Technologies is one of the world's largest water treatment companies and is regarded as both a pioneer and innovator in the area of ultraviolet water treatment for the home.

The Trojan UVMax product line includes a wide range of models suitable for almost any conceivable residential and light commercial water treatment application. The Trojan UVMax Model A through Model F4 is a popular and economical line of point-of-use and whole house models. The Trojan UVMax Models A and B4 are designed for point-of-use applications, whereas the Models C4, D4, E4, and F4 are designed for whole house point-of-entry applications. The new up-market Trojan UVMax Models G, H, and J were designed for higher flow rate applications, and the popular Pro Series Models Pro 10, Pro 20, and Pro 30 were designed specifically for applications where NSF certification is required or desired.
