Reviewed in the United States on November 11, 2017
This is my second RO-PH90 system. Simply one of the best systems on the market, in my opinion. Uses genuine Dow filmtec reverse osmosis membrane. As anyone familiar with RO knows, filmtec membranes are the gold standard and rank among the elite in rejection rates. This is not your generic RO bought in a hardware store, although some large chains carry it. Input TDS = ~225 ppm, output TDS = ~15-20ppm. Does the job. Have not tested PH yet. Water tastes great as it does with my first system. Change your pre filters once per year or at the recommended %TDS interval and expect this RO membrane to last its full schedule of 3-5 years. This is very important. Incoming water pressure must be at least 50psi in my opinion, for this system to operate as intended. At 75psi, outgoing pressure is like a dream, even with 1/4'' stock tubing. Fills glasses quickly. Consider the 3/8" output upgrade if your input pressure hovers at 50psi as it did with my first unit. RO systems thrive on incoming water pressure, this is the most important aspect of setup! Do not skip!

Simple setup as usual, although this time I needed a booster pump, incoming was 40psi at best. Remember, it can fluctuate significantly during high demand/peak times. Plan a few hours for someone not so mechanically inclined. John Guest quick connect fittings are painless. Manual is very thorough, follow each step carefully and no problems should arise. If they do, customer support is USA based and very helpful. Download and read the manual available on their website before purchasing so you know what items and skill level are required. Anyone with a few tools and willful attitude will have zero problems.

Easily found an Aquatec CDP6800 kit on Ebay for $108 that is perfect for this system. Came with all needed lines, pressure gauge, shutoff solenoid, pressure switch, pump and transformer. Make sure to have a sediment filter before the pump if you want it to last. Of course, APEC also offers a version pre outfitted with either permeate or booster pump although you will need your own gauge I believe.

If planning on wanting 3/8" output upgrade for PH model, please go directly though APEC to purchase with it pre installed. Do not buy the output kit here on Amazon and expect it to fit the PH filter on your unit, it will not. It is for 5 stage only. You would then have to buy a 3/8" PH filter from APEC, about $40. Save yourself some time and money going directly through APEC for the upgrade route.

Not much else to say, please READ the manual and you will not have to think about this system but a few times a year for TDS tests and scheduled filter changes. Good luck!

5.0 out of 5 stars Best Instruction Manual Ever
Reviewed in the United States on February 16, 2020
~1-year update

So I changed out my filters. I hesitated to buy this product because our town's water quality reports always had great numbers. Still... worried about PFAs and such, I went ahead. Well look what I found!

The picture with the filter in the housing is the sediment filter after a year of use. The next picture compares the old sediment filter with the new one. The three filter picture shows you the three filters I replaced. Water hits them from right to left. You can see that by the time the water gets to the third filter, it's in good shape because that third filter is still pretty white.

The bottom line is that, even with good water, there's plenty of muck to filter out before you drink.

=============================================

So I just installed this system and it's too early to give you any information on how it performs over time, but what I can say without hesitation is that the instruction manual is the best such manual I have ever read and used in 30 years of DIY homeownership.

I've done all sorts of things. I pull my own permits, I've installed appliances, done framing, bought tons of tools, and more. It's been a non-stop passion of mine for decades. After all of that, this is really, honestly, the best manual I've ever read. Well-indexed, plain language, plenty of useful diagrams, written for somebody with no experience and handy for somebody with lots.

This is no small thing. If you're wondering whether or not you can handle this, rest assured that you'll have plenty of guidance. Just set aside plenty of time, take your time, and do what the manual says to do, step-by-step, without skipping anything or jumping ahead.

The equipment itself seems top-notch and all things were supplied and worked as they should have. Be careful unpacking as there are some small parts that could get away from you.

I installed my system in my basement, just below the sink in the kitchen on my first floor. It would have been handy to have an extra couple of feet of tubing for that, but I had enough. I also installed a water pressure meter on the feed line. There are plenty of inexpensive tubing accessories that you can get. I got a variety pack and added a couple of elbows and what not to get a cleaner installation.

So my hat's off to this company. I got an expensive system, but feel it was money well spent.

The beast takes a lot of room under the counter but we love it. Wouldn’t want to do without. The water is delicious and no longer smells of chlorine, is crystal clear and yet doesn’t taste “dead”. Thank goodness hubby has plumbing skills. It wasn’t that simple to install.

Es un sistema super padre, fácil de instalar aún cuando tuve que perforar granito, pero eso es otra cosa, las instrucciones son sencillas, considerar colocar muy bien el teflón en las terminaciones de metal y contar con la herramienta necesaria, el tiempo de llenado fue poco más de una hora ya que cuento con bomba de presión para todo el sistema hidráulico. Consideren tener buena presión o instalar una bomba con el sistema. No tiene sabor y no tiene acidez.

Update 2022

Maybe look elsewhere, trying to get Abby kind of support from these folks is impossible. No phone, email or anything will get an answer.
--------------
One of the few systems were every important component was not made in china.
The tank is made in Taiwan; had to fill and empty 3 times to get rid of a cloudiness to the water.
I ended up gently shaking the tank when full and that worked perfect.
Most likely just residue from the automated welding.

The quick connect plugs work well and don't leak.
You can even disconnect them as easy; just hold the tab down and pull the hose.
Just be sure to have nice clean square cuts on your hoses (they dont ship that way).

Unit assembly entails inserting filters into holders and twisting them into place.
Installation is straight forward, but a few tips:
- Once you have everything connected, but before you turn on the water.
---- Turn off the tank tap; first fill the system with water and work the air out.
---- You can help by lifting either end of the filter unit to move the air bubbles along.
- After you have gotten all the air out; proceed to flush the tank as many times as required.
---- It does indeed take a few hours to fill.
- Does not need to be mounted, can stand on its own.

One note, its nice that it doesn't require electricity.
But keep in mind this is not for low water pressure homes (you need a boost pump).
I will most likely add a UV filter unit at some point; so I will need to find power then.

Water tastes fine, no grittiness or anything.
Specifications from the manual are attached.

--
I wanted to add that this is a better/higher model when compared to the usually more expensive ULTIMATE RO-90 (this being ULTIMATE RO-PH90).
