RO/DI components are made by a couple of companies and sold to anyone wanting to assemble them and sell them on E-bay or anywhere else. This is a HIGHLY competitive business
(meaning, you don't have to pay a lot of money to get a great system) A UV on an
RO/DI unit is a waste of money unless you are in a known contaminated area. Here's a link to the 100 gpd Aquasafe System Maximus II system that I use and have been recommending for several years.
AQUA-SAFE MAXIMUS II REVERSE OSMOSIS WATER FILTER - eBay (item 160200952146 end time Jan-25-08 19:00:00 PST)
This is a great product from a reliable company. I have not heard of one complaint from those here on TR that have bought one. Save some money! You don't need the UV on an
RO/DI unit.
