RO/DI Filter replacement time

[devlzluv]

So its finally that time to change all my stuff out. Main reason im doing this is due to the fact I want to save on water. Im going to be doing a dual membrane with a booster pump and dual DI chamber. Now I have looked up my local water source testing and need some guidance on the filters/membranes I need to get the best water quality. Heres my waters info, it also come out at 137-154 TDS prior to entering filter, I am getting 2-3 tds from the membrane to DI chambers which then goes to 0 prior to entering the second DI chamber.

Chloramines and Chlorine (ppm) 01/19 – 12/19
Level detected - 3.2
Range 0.33 - 4.7
MRDLG - 4.7
MRDL=4.0

Fluoride (ppm) 1/17
Level Detected - 0.57

Are you looking to replace all of your filters including your membranes?

Honestly yes, I dont believe my membranes are damaged so I may change those later. 1 is brand new and the 2nd one has been used for about 2 years.

I would look at Spectrapure membranes and filters myself. I use Spectrapure prefilters and membranes then have a three stage DI system with BRS resins
