This company is so professional. During installation, I got stuck and wasn’t sure what to do. I was totally stumped and decided to give them a call. A wonderfully helpful lady named Angie took my call and patiently heard my out. She realized that I was missing a small part that was necessary to complete the installation. I couldn’t confirm if I had lost the piece during the unboxing, or if they had forgotten to include it in the box. It was no matter to Angie, and she immediately set-up a replacement order to send me the missing part for free. She told me to call again if I needed anything. In a couple days when the part finally arrived, I breezed through the installation and had it running and spewing out clean water in no time! I wanted to call Angie just to show my appreciation, but didn’t want to crowd their phone lines. They’re probably really busy. So, I’ll just say it here. Thank you, Angie!

Let me say that this RO system is the simplest and easiest I’ve ever had to install.). I have a couple nitpicks with some small design choices, but those complaints are entirely subjective, and I won’t get into them here.The system is well-built, and it should perform well for as long as you keep an eye on the state of your filters.

I’ve had a rotating carousel of on-tap filters and pitcher, but none of them lasted long. They were fickle instruments and would “go bad” on a whim. I needed something more solid, more consistent. I decided to take a gamble on this alkaline under-sink system and it has been exactly what I was looking for. Thanks!

I tested my water before and after I got this system. (I made to sure to test the “after” water when it hasn’t yet touched the Alkaline filter) The TDS has dropped over 300 units! From 387 to about 45. I am thrilled to see such a massive improvement

I used to have to deal with the horrible Whole Foods parking lot and lines just to get some filtered RO water. Hopefully this unit will save me some serious time and money!

This is the 3rd time I’ve installed an RO system, and it was by far the easiest. And maybe I’m simply getting better at it, but I really think the instruction manual they included in the box helped.

I love this system! Not only is it healthy for me but helps the eco system by not having to purchase water bottles! I have already told all my friends and family to make the switch!

The only problem I have with the product is the lack of a UV bulb. I live in a big city, so I probably won’t need it but I’d like it anyway. It’s always better to be safe than sorry.Despite that, this product is still the complete package. And it features the ability to be upgraded. I can simply order a couple parts and a UV bulb and add it onto the system. I haven’t gotten around to it yet, but it should be a relatively cheap and easy project. For now, my water is still delicious and healthy.

We recently moved in to a new house not too long ago. It was a bit rough around the edges, but we knew with a little work it could be perfect. One of the worst parts of the house was the plumbing. Just everything about it was too weak or too old… so we called in a plumber and he worked with us and we replaced the entire system – new pipes new everything. So, we finished, but my wife mentions that we did all this work to the water system but we’re still drinking the same water… funny right? She didn’t mean anything by it, but she made a good point. Why not make the one improvement that really matters when dealing with water? So we began looking at various water filtration options and decided on this Express Water RO Alkaline Filtration System. We called back the plumber to install it and finish the job we started.It was definitely worth it. Our water is now noticeably cleaner and it just kind of changes the entire vibe of the house. Thanks, it’s been perfect for us!

Took quite a bit of water draining to get it drinkable and it continues to leek from the middle filter. Not sure why that would happen because everything was done as said. I guess when we figure it out or take it in I would say it’s a good machine but so far will be more work with the leak.

Have been using this system for 3 weeks. No more plastic bottled water for me!It was easy to install, water tastes great, and I’m very satisfied with it!

Our kids convinced us to get a filter system that produces alkaline water. They heard some stuff in school from a teacher, and they laid some great arguments. Wife and I agreed that they might actually be right! It’s supposed to be healthier for you, and I’m looking forward to see how it treats us in the following months.

Needed to replace my old Ro unit and decided that I’d like to try something a bit new this time. I thought an alkaline filter could really take my water to the next level of quality and taste… and that’s exactly what it did!

I decided to get an RO system because there was clearly something wrong with our tap water. It had this terrible smell.I also wanted it to be Alkaline for the added health benefits.So far it’s been perfect for us. The smell is gone and the water tastes better.

After using the same RO System for years, I needed an upgrade. I came across express water’s alkaline RO system and it seemed like it was I needed. I really liked the price of their replacement filters and accessories. So, I went ahead and got their Alkaline RO system. It came with free replacement filters and a water storage tank.Thanfully installtion was fairly easy. And my water definitely tastes better now. So I would definitely buy this system again.
