As someone who used to work in the R&D section of an RO system manafacturer (this was years ago), I’m so happy to see the leaps and innovations made in this field. Back then, you called a plumber to install the system. And if you were a plumber yourself, you’d still call another because the process was so unintuitive and slow. Now it’s so simple! Installation was so easy. I just hooked it up under the sink, did a few pre-use washes, and I was done. And, more importantly, the water coming out the other end is pristine. These new guys are putting me to shame!

I still haven’t found an ideal spot for all my cleaning supplies since I cleared out the under-sink cabinet for this system. But that’s a tiny price to pay for clean/good-tasting water.

I’ve never done business with Express Water before, but their Alkaline RO system has left an impression on me. I think I’ll be coming back to them for replacement filters for years after this, if this first impression is anything to go by.The system I ordered arrived on-time and in great condition. I wouldn’t call installation easy but it was as simple as it possibly could’ve been. And I have nothing but praise for the taste of the water. So delicious!

It’s been great so far. The water is pristine and refreshing. Save money and install it yourself, it’s very easy just give it a try!

Water pressure was a point of worry for me before purchasing. But I can now confirm that pressure is good. I still wish RO systems were a bit quicker in general, but this system definitely has above-average speed.

Have been looking for a water filtration system for some time and we hit the jackpot with this one. For the price, this is the best system we found. Installation is easy if you are somewhat handy and the water taste great. Two other family members have purchased the system and all of them are very satisfied. Highly recommend this product.

Water taste has got so much better since I hooked everything up under the sink. I had a hard time putting everything together, but I’m really inexperienced with handy-work like this. So, it will probably be way easier for most other people. In any case, it is very very worth it. You will not regret installing an alkaline water filtration system, especially one of this quality.

Our well water used to have really low pH, around 5.5. After doing some research, I decided to raise the pH to at least 8.0. This system has been consistently giving us 8.1 or 8.2 – which is ideal. It truly makes the water taste so much better.

It’s a great filter system from 300 points tab water to 50 pts with the filter. It tastes just like good bottle water. Lower is better for TDS quality.-John

The subtle way everything’s color-coded (which makes installation very easy), the tasteful deliciousness of the water it produces…

Superb value and tasty water. Comparing prices on the web and nothing else comes close. Saved so much cash.

The faucet that comes with the order fits my kitchen’s aesthetic which is a nice little bonus. Honestly, the water quality is so good that it would’ve even made an ugly faucet worth it.

Can’t live without this system!!!

RO systems aren’t cheap but they are a great investment. They will save you money over time and could be a great boost to your health. Plus, the benefit of not having to leave your house for clean water during a pandemic can’t be overstated.

This unit makes real natural alkaline water so pure tasting. Hooked it up to my ice maker also and my ice is crystal clear! I live in southern California so our water from the Tap is not something you can drink or make good ice with. Very satisfied with this purchase.

work as intended but price to high and due to filter change is pricey at the same time.

Over the past 25 or so years, we have had an RO system installed. When we purchased our most recent home, the drinking quality of our water was disappointing and the taste left much to be desired. My wife recently discovered the benefits of alkaline water so when I found an RO system that produced it this system was an easy choice.Since moving, we’ve been Buying, lugging, and disposing of bottled water containers. Now, I merely turn the faucet, and I have good tasting water (health benefits for my wife), convenient as our kitchen sink. Great tasting coffee, drinking water, and water based beverages. Recommend this product to any one who appreciates good water.
