Express Water ROALK5D 10-Stage Alkaline Under Sink Reverse Osmosis Water Filter System, NSF Certified 372, 50 GPD, Reduces 99% of Impurities, BPA Free, Deluxe Chrome Faucet

Water quality is great and taste great, smaller than other ro systems, super good for the price, easy to install, I had it for almost 2 years and haven’t had any issues, no noise and very duarable

Simple and amazing! I live in a city with awful water; it’s terrible quality, full of forever chemicals, and tastes like dirt. We were slaves to one-use water bottles until this easy solution. Installation is simple enough and the customer service was excellent when I had questions. I’m an advanced-beginner home DIY-er and with the videos and written instructions, I installed this over a few days taking about 2 hours each day. I took my time double checking everything at each step. I experienced no problems or leaks. I’ve had it installed and running for about 3 weeks now. I did a lot of research for which filter to use, both brand and type. RO with remineralization is the best way to go. This brand does it all and at a great price with easy self installation. I would recommend this to everyone, seriously. It does require a separate beverage faucet, which I thought I didn’t want at first. I thought wanted every drop of water in my kitchen sink fully filtered. But without pricey full-house filters, that can’t be achieved. This is a nice alternative that lets you keep water pressure for washing dishes. The beverage faucet itself has great flow rate. Size: I have a small amount of space under my cabinet because I have a large disposal underneath. It still fits beautifully and I even have space for a little bit of storage under the sink. I have a one drain sink with a disposal, and I had to buy a separate attachment to make sure the filter drains properly. A plumber gave me the attachment tip. We’ve been making ice and drinking clean, great tasting water and we’re so thankful for this affordable and amazing product. Get it.

Very Pleased with this product so far! Got it in a Double box that included everything organized by box and extremely well packaged. Faucet is very sturdy and clean looking, all stainless and feels heavy duty. Components are very well made. Price point is just great! Installation took about 1 hour following video instructions (available on Youtube). Everything fit just right without leaks on the first try. (Be Careful when installing plastic threading on metal components. Make sure that the threads are straight and you'll have no problems) Follow the manufacturers recommendation for system flushing and youre all set. Installation requires drilling to tap the drain before the P trap and if you have to drill a hole for the faucet. Other than that, the rest is just Screws and Pressure Fittings. Water Quality is the best! Re mineralization adds those minerals that help with hydration, alkalinization and de ionization takes that water to heavenly status! Would recommend any day!

Love this filter. Install was easy with the provided instructions. I have it hooked up to my ice maker as well. Water never looked so clean and tastes great!

I bought this system about midway through 2025 and have had zero issues with it. This does an excellent job of filtering out all the nasty particles and tastes from our city water. Hook up was very easy to install. Love this filtration system and it is very affordable.

As some others have noted, installation is straight forward and a bit of a challenge for the plumbing novices out there. It can be done without getting too upset, I assure you :) The directions are easy to understand. The color connections and water hoses make connecting the correct line to the correct filter simple. Mounting the unit in the cabinet under the sink can have its challenges, especially if the space is unusual in some way. I only had one place to mount the filter holding unit, and it was not in a convenient location to get to; behind and within inches of the sink drain pipes. Maybe asking a friend with an easy going attitude to help could make the process more enjoyable? lol And let's face it folks, you are going to ENJOY this product. Are you over fifty and wanting to remember what it was like visiting a family member's farm for a totally refreshing glass of cool, satisfying water? (probably from a well system) Are you under fifty and wishing family farms were still around for you to get a body nourishing glass of water from? Then you have chosen correctly. This filtration system brings to mind what water used to be like for me as a child. This product is designed and constructed with integrity. That's a fancy way of saying you won't feel like you over paid for a water filtration system. The packaging was clearly marked, and contained all listed items required for a successful installation. (minus the attitude adjustment - lol) I personally have paid for water delivery for over 8 years now and am looking forward to lowering the cost. I would recommend this product. One last piece of advice: Make sure to give yourself enough time on installation day. The filters need to be primed, as well as the holding tank filled and drained several times to ensure a quality product is delivered to your new faucet. And in my case I needed some extra time for color coded lines and fittings, and colorful language too :)

So it’s been almost 2 months since I’ve purchased this. I love it. I’m kicking myself for waiting as long as I did because I really believed my PUR dispenser was doing something. That being said, the directions when assembling, was confusing. I think it’s suppose to be a very generic instruction manual that covers multiple different set ups. Ignore the instruction part and just look for the picture set up. Match the colors of the tubes to where they’re suppose to go. It’s honestly not that challenging. Also, there are these little cotton rounds to trigger the auto shut off, I recommend messing with the auto shut off first and making sure you’ve got it hooked up correctly, then putting that round. I wasted one and they’re not reusable. Not a big deal because it came with two and ordering more wasn’t difficult. Other than that, we love this. I fill my nugget ice maker with this filtered water and it does not get a mineral build up like it did with my PUR filter. I was having to descale it at least once a month as well as pulling it apart and scrubbing the heavy build up areas. None of that in the two months I’ve been using this water in it. The water tastes great. I was hesitant on if I really wanted this set up or maybe a smaller one, but I have no regrets. The tank is great, the water pressure from the faucet is great. I love it. One more thing, I will say, you will need someone with a strong grip to screw these filters on. It comes with a handle thing to help but I found it to still require a lot of effort to get it tight enough to not leak when running.

I have it for more than a year now and love it! Clean water for me is a must and this do it's job. Never had any issues with it, no leaks, easy to install, and filters it pretty easily and well. We live in a household of 5. This is a saviors. It's also much cheaper than other brands

Muy muy bien, no tuve que llamar a algún técnico, te dice todo de como instalarlo, el agua sabe muy bien, también lo conecte a mi refrigerador y listo agua y hielos, estoy muy satisfecho por el sistema espero vendan los empaques o refacciones por si se necesitan

For the money this is hands down one of the best systems. It was easy to install. The flavour of the alkaline water is great. We hooked it up to the fridge so it took a bit more to install it because of all the filling and emptying you need to do to get it set up. Before connecting it, I hooked up the faucet temporarily and drained it into the sink. The first day or two, there was a strange rubber-like flavour in the water. This is normal. The rubber bladder inside the tank needs a few cycles of expansion and contraction to loosen up. If you get that flavour or rubber, all you need to do is to completely drain the tank 2 times and then it’s gone. But make sure you drain it to the point where the water comes out as a trickle and you’ll know it’s completely empty. I have had it for 5 months and I think it’s ready for the first filter change. We have not had a single problem with the system. It does make a funny sound every once in a while but that’s just the bladder making noise. It’s a great product at a great price. Very well packaged and easy to understand instructions. It took me only 45 minutes to set it up.

El producto llego a tiempo y es de muy buena calidad. No fue fàcil de istalar pues hubo que pasar una manguera hacia el refrigerador y fue un poco complicao pero por el sabor del agua, valiò la pena

The small town I live in is terrible with their water system. If it doesn't smell like chemicals and yellow looking. It smells like frog water and is more brown than yellow in color. I installed this unit and now my water is great. No nasty smell. No nasty tasting water. No nasty film on dishes or in the pet's water dishes. The water comes out clear with no smell other than clean drinkable water. I only wish our town water treatment plant used this kind of system. I bought this for my brother's house warming gift and they love it as well. It was easy to install and the color coded tubes make for a snap as to what goes where. I looked around for water systems in my area and this was by far the better price than what was locally available. Had some issues with getting a refill set to come to my area off Amazon, but the company handled that fast and easily when I contacted them to notify them of the issue.

Where do I start? Firstly I was originally going to get the Big Berkey. But the more I thought about it the more I realised that this was far better value for money. The product came very well packaged. And it was very easy to figure out how to install the unit. One thing that should be noted though is that you need to take your time. Check and recheck before you do anything. And don't skip any steps. Treat the unit and the filters with allot of care. It just takes one good bump to crack something and then your done. Once installed follow the start up process. Flushing the system 4 or 5 times fully. I did 8. By the end of the flushing the water will be so pure it has virtually no taste. It's like drinking silk. It's delicious and so refreshing.
