Hi..just curious to see what units that some of you are using and if you are happy with them. I did a search and didn't find many posts on it. Anyone buy any units on Ebay (filtersdirect or Aquasafe)? Thanks. Frank
You definitely want RO/DI. The ebay units are fine. One was reputed better than the other but now I can't recall which. I have one which is identical to aquafx. 4-stage. Some say go 5-stage.
My motto is, "zero tds is zero tds". Whichever you get make sure the price includes a handheld tds meter (get them to throw one in), or better yet an inline meter.
