APEC Water Systems PHPLUSKIT-14 US MADE 10" Alkaline High Purity pH+ Calcium Carbonate Inline Filter Kit with 1/4" Quick Connect

What a difference this filter made. I ran 3 gallons through it before drinking. It got even better as we used more. Really fresh and refreshing drinking it. I'm glad I got it. Easy to install too. About 5 minutes.

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.

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!

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.

Working good after flushing the ro system maybe 4x

When it's time to change this cartridge or whatever you want to call it I can definitely tell. I recently inserted a new one and I finally feel refreshed - on the one that was past its prime I would drink and drink and drink but never feel like I ever quenched my thirst. Now I'm finally satisfied.

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.

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.
