   I have a 5 stage RO system in the kitchen which also feeds the icemaker in the fridge. RO water was ok and didn’t have an off taste, but I was concerned about the water being to acidic. When you drank it, it was leave your throat with a dry-like feeling. Nothing major, but I thought I’d give this mineralizer a try. SO glad I did. The water tastes great and is far more refreshing! I find myself drinking much more water now than I ever have. I haven’t had it long enough to tell how long this will last before needing replacement, but I will definitely purchase again. Only took 10 minutes to install and the kit had everything I needed to do so.

   Don’t listen to the negative reviews stating it’s used. Pictures of the ends that look like the tube is cut off. LMAO. They are inserts for shipping placed there from the manufacturer not a used part. I ordered the kit with the holders and 1/4 in tubing and was absolutely brand new.
   This is the first time I tried this stage 6 filter and I think it’s terrific. I was concerned about taste but it’s barley any different and I can even say it’s slightly better. Better for your stomach since the RO water is acidic. I have been with APEC for many years and will stay with the 6 stages from now on. For reference my water is from a well and TDS is about 700-750 ppm. 20-25 ppm with 5 stage RO and about 40-50 with this stage 6 filter as of today.

   UPDATE: All mt stomach pains went away within a day of using this filter. After a couple of years of stomach pains and as a last resort, I added this to the ro thinking the ro water water was causing my pains. Well, it was. No more stomach problems and pain and no more pepcid. I’m sure other alkaline filters will do the same.

   This is to add minerals so, not taking trace minerals anymore. The water tastes even better, which I thought not possible, but it is. Easy to hook up.

   The pH of my reverse osmosis water before adding this filter was between 5 and 6. I wanted to make my water a little more alkaline so I bought this. I tested the water shortly after adding this and the pH was exactly the same. I waited a few weeks and tested again. The pH is still between 5 and 6. No noticeable difference on the test strips. Disappointing.

   This product was easy to install. I needed to get 3/8” to 1/4” couplers x 2 and added a shit off valve before and after the filter. I know it shows it installed under the sink but for easier replacement I installed it in the basement on the faucet supply line after the RO and pressure tank. Haven’t had a chance to check pH yet but will in a few weeks to see if it’s doing what it is supposed to.

   We added this into our APEC RO90. We used it about a week and didn’t really like the flavor. I decided to test it to see how alkaline it was to incentivize myself to keep it. I was expecting it to be alkaline, but not only was it not alkaline, it was way worse than tap, even more than I expected since RO removes minerals too. We decided to remove it and wait awhile to test the RO again with the tanks flushed. I was upset to find that removing the filter made the RO water more alkaline and not the reverse, which is why we’re all buying this thing I assume. So, APEC please try again. We need alkaline water, but this was a HUGE failure. I am returning.

   I added this to my APEC RO. The water tasted almost the same to me. The PH was also unchanged. The part that worry me the most was the cloudy water. The cloudiness was gone after left the water sit for a while. The most issue was the small white particles that left under the glass. It looked almost like tiny grains of sand. I took it out and returned it. Waste of time.

    The filter might be fine but the tubing they send with it was way too large in diameter. I had to go buy the correct tubing! Frustrating to spend more money when I already paid a lot for this item!

    I’ve had the Apes RO system for about 2 years now. Initially our TDS was at a 4 (yes, 4) when it first installed. After 2 years of constant use by a family of 4, the TDS is up to a 7, still in a great range. I was curious what the PH was and bought a tester. With the TDS at 7, the PH was down at a 6! Not too acidic, but not where it should be for normal drinking water.
    This PH+ kit is super simple to install. Took me a total of 6 minutes, and 4 of those were getting tools before the install and putting them away after I was done. After flushing this for the recommended time, our TDS went up to 19 and PH went up to 8.5. There is no real noticeable change in test, slight change in feel of the water as it is more wet if that makes sense. The taste is more crisp now without the dirt flavor like Fiji water.
    Overall a great addition to our Apec RO system, highly recommended! You need this! Buy it now!
