I added this to my 5 stage system. I was getting from 200ppm down to 10ppm with my 5 stage system, now with this extra stage, Im down to 0ppm.

iSpring is a great company and love their customer service. I have a unit that is about a 9 months old, but gets pretty heavy use. I had a problem with bad smelling water and after replacing this FD15 water was great again. Went from 8PPM to 0PPM.

Perfect, works as it should. With one of these you will get 6800 ppms filtered. That is in the vertical position, with my 2 stage Di I have been reading 000ppm from the first test. I always filter water through the membrane on startup for a minute to flush it of water thats been sitting in it. From the membrane I get a tds reading of 15 ppm, estimated 453 gallons for each Di (6800ppm÷15ppm).Great product, best part is its refillable. ~$10 for refills

I connect this to my RO machine and it have been producing water from start to end with zero TDS.I use to have to waste the initial few minutes running the RO before producing zero TDS water, now I just turn on the RO and straight away getting clean water.
