Almost 15 years ago I bought my first 5 State Max Cap RO/DI unit and loved it. Customer service was pleasant to work with and sent my missing part right away. I did try a unit off of Amazon 2 years ago but it only gave me 0 TDS for a couple of months. I tried upgrading it but still didn't receive 0 TDS. IDK if it was a design flaw but I went back to Spectrapure. Don't be undersold and accept no substitutions! SPECTRAPURE IS BOSS!
I wont be shopping anywhere else but spectrapure
Glad to hear that you are happy with the system.
