The best RO system for purifying water.
Last weekend, the quartz sleeve on my UV filter broke, and I had to replace it with a new one, so I upgraded to a deionization water filter. It worked perfectly.

Ion replacement water filter
These filters improve the quality of the water from my RO filter. I had to purchase these separately . It was a great deal on replacement filters.

Works for me
I bought this as a sixth stage to my existing RO water system. We are getting into the marine aquarium hobby and I wanted to reduce the TDS in my water. We are on well water and with my current RO system we are going from about 220 to 7 TDS. I was hoping to cut this in half. At first I was skeptical as the TDS reading went up to 13 or 14 and stayed there for several gallons. I was about to return it, but decided to wait until the morning and try running it again for a few more minutes. After that the TDS dropped to 0, yes zero. Very happy now. I have this set up so only my tubing for the tank uses the RO+DI water as I don't feel taking it below 7 is necessary for everyday use. IF you get this, give it a chance. I probably ran 5 gallons of water thru it before the readings went down. Or maybe it was waiting overnight IDK, but I filled a small nano 32 gallon tank and the readings were still zero as of the last gallon of water.

A Must Have. Read review.
I'm 64yr. Did a lot of reading and wrote a review for the Express RO system. This filter is a must. It actually removes Micro premanant bad elements, micro-plastics from the water the other filters do not. This is a must if you are really interested in having the cleanest water possible.

Doesn't get it to 0 tds, sits at 2 for me. Will test further.

Reduced ppm
I live in Las Vegas where the tap water is 1300 ppm I bought a ro system and it reduced the ppm to 100. I added this filter and it’s brought it down to 4. I’m very pleased with that.
