  • Hi there hope this finds you guys well and surviving tough times. I bought a water treatment set with u v light and have replaced filters last year. My system is installed in the water mains so it is just extra for my piece of mind .I normally just get the 2 different micron filters and 1 carbon .You have different options . Do i stay the same or change to different combination.


    There are many options that work in these units. Generally we normally offer a 20 micron then carbon followed by the last filter which can be 5 micron
