Express Water RO5DX 5-Stage Under Sink Reverse Osmosis Water Filter System, NSF Certified 372 & 58, 50 GPD, Reduces 99% of Impurities, Deluxe Chrome Faucet

The best health purchase we have made in a while!!! The product came fast it came with an extra set of filters for the three main stages of filtration. It came with fittings to install completely with a simple set up. I laid out the set up to decide if I needed anything extra to install under my sink. I have both a ice maker and a small hot water heater for instant hot water for herbal tea under the sink and I wanted both of them to get the filtered water as well... So I needed an extra 1/4 inch tee and a few feet of 1/4 poly which I went to the hardware store to buy... You can design it how you want and I also got a 1/4 inch shut off to put on my line that feeds my hot water heater, so I can turn it off and work on it if I ever need to and not have to turn off my filter water... Make your own plans and go to the hard ware store and get the advice from the workers there and just go for it and you will not be sorry, because this is a great purchase. I contacted the seller and got semi clear covers and they were awesome to work with, but clear is not recommended because it could introduce light into where the filters are and theoretically introduce light grown organisms... So it needs to be where NO light will get to the filters, if you choose this option and the cans are off clear and if I had to recommend one or the other, I would stick with the white as they are the best; but I wanted to mention it as this company is so good and responds to your needs so well and I felt obligated to let others know that they will take care of you if you need something... I was curious how the ice would be after we installed this system and as others had said ... the ice was almost clear, which was cool :)... I will add this as it might be something you do it your-selfers might want to think of doing... While I had everything removed from under the sink, I also got a small piece of lanolin and put it under the sink and brought it up on the sides a couple inches and calked in so that when any water does spill, when changing filters, or simple wear on valves / faucets (as it is inevitable over the years) it is no problem whatsoever and it looks nice and clean and was so cheep and simple to install... (note: I made it so if ever there is a leak on any of my many fittings, water will come out the front and onto my sink rug and I will notice it and not have any problems going under cabinet/down stairs... looks good too) Water quality when measured at the same time from the regular faucet and unfiltered using a TDS unit (total dissolved solids) purchased here on Amazon is at 254 ppm (parts per million) and after it has been filtered through this unit, it was at 17 ppm and a week later it dropped to 14 as it cleaned out I guess (if I just barely touch the water with the tip or reader it is below 10 and if I Put entire end into water it is at 14 (It might get a bit lower as it gets more water through it, and water; and obviously, minerals will differ from one location to the next... ).. Water tastes similar to distilled water as compared to our regular water... We could not be more happy to have this very inexpensive and quality system in our home and the extra security of having pure water is awesome!!! LOVE IT

I’ve been using this reverse osmosis water system for about five months now, and I can honestly say it’s one of the best upgrades I’ve made for my home. Even after months of use, my TDS reading is at 9 ppm and the water still tastes like bottled water. The difference in water taste is huge for me, it’s incredibly clean, crisp, and refreshing. Even guests have commented on how good it tastes. Five months in, the water still tastes just as pure as it did on day one, which really speaks to the system’s reliability. It’s made a noticeable difference not just for drinking water, but also for coffee, tea, and cooking—everything tastes better. Installation was straightforward, although I will say the filter housing can be hard to screw on, I had to use a hammer to knock the wrench to get it tight. Overall, this system has been well worth it for the peace of mind and the consistently great-tasting water. Highly recommend to anyone considering making the switch from a Brita!

I've had RO systems for the better part of 20+ years. Our household goes through a lot of fresh water daily, so having an RO system has paid for itself many times over. Even if you don't go through a ton of water for drinking, cooking, iced tea, etc...the convenience of not having to buy unlimited amounts of bottled water and/or filling water jugs at your local water store is definitely an added bonus. I've had 3, 4 & 5 stage RO units throughout the years and they've all produced great tasting water. My past 3 or 4 RO units (which are usually purchased when we move houses) have been Watts Premier models. They specialize is very fast & easy filter changes and they are definitely easy filter changes. However, you pay a little larger price for that convenience. Their 4-stage RO units run about $200 and the yearly filter changes run about $60. RO units also have 2 types of faucets: 1) faucets with an air-gap and 2) faucets without an air-gap. By definition: "Air gap faucets were designed to protect the RO system. In the event of clogging, a small amount of air, rather than dirty water, would go back into the RO system". The air gap will always make some noise when the tank is filling as air and water pass through the drain line and sound escapes from the little air gap hole. The Watts Premier RO systems have an air gap. If your system has an air gap, you cannot replace the RO faucet with a non-air gap faucet...you need to replace the faucets (if necessary) with the same kind. During my most recent search for an RO unit to install in a new home purchase, I came across this Express Water RO unit at an amazing price (which included a year of filter changes). I was a bit skeptical given the price, but the amount of solid reviews made it an appealing option. I made the purchase and had friend help with the install since I am a large framed man that does not easily fit under the sink area. After a month of use, I can say I am very happy with the taste, performance & overall experience with the RO. With that said, I found myself missing the benefits of the permeate pump that I had installed in my last house. If you just care about the RO review, then I am very pleased and give it 5 stars. If you want to know what a permeate pump is and WHY you should get one, read on. This is the permeate pump available on Amazon that I purchased and am reviewing below: https://www.amazon.com/gp/product/B005VPPRX4/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 Let me start by saying I will NEVER have another RO system without a permeate pump again. Permeate pumps use the wastewater that is expelled during the RO process to greatly increase water pressure at the RO faucet, minimize wastewater and fill the tank in less time. They can be installed on nearly all standard RO systems aftermarket so there’s no need to buy a bundled RO system that includes the permeate pump (since most of those cost a lot more than buying the units separately). I was introduced to permeate pumps about 4 years ago. I purchased a Watts Premier RO system from Costco (when they still sold Watts Premier) and had it installed by a plumber (since I needed a hole drilled in my granite countertop). I consider myself pretty handy and although plumbing in general isn’t rocket science, I’m a large framed man that hates trying to squeeze under sinks to do pretty much anything plumbing related. After the RO was installed, I was getting smaller (and broken) pieces of ice at my refrigerator since my RO was feeding my ice maker through a longer 1/4” line from the kitchen island to the refrigerator. This a drawback of a lot of RO systems which feed ice makers that aren't in very close proximity. After researching I came across a permeate pump (sold through Watts Premiere) and made the purchase. The included instructions were specific for the RO unit I had and it was an easy install since the RO was already up and running. Immediately, you will notice several things with the permeate pump. 1) Permeate pumps make some noise. They generally click or “thump” every few seconds. This happens because the wastewater from the RO builds up pressure inside the pump that is then used to push fresh (permeate) water into the storage tank. When the pressure builds and releases, you get clicking or thumping until your tank is full. 2) Your RO faucet pressure increases dramatically. As a result of the increased permeate water being forced into the storage tank, the tank pressure within the tank bladder increases and you end up with water pressure comparable to your regular faucet. The line pressure at the refrigerator & ice maker (assuming you have them all hooked together) is also the beneficiary of the increased pressure and you get full sized ice cubes again. So, why wouldn’t everybody want one of these? Well, I think most people have never heard of them. If you have, then the results speak for themselves. HOWEVER, these do make noise...especially if your RO faucet has an air gap (that little hole in the back of the faucet that inevitably leaks water out of it when the drain line gets blocked with something). With an air gap, permeate pumps get VERY NOISY. The pump action not only clicks (or thumps) under the sink, but the air gap sound created from the pump gets much louder as well. The air gap noise on my Watts Premier Pure Plus unit was so loud I actually debated on getting another permeate pump in our new house. I ended up buying a highly reviewed non-air gap RO system from Amazon and had it installed for a month in my new house. As usual, the water taste and purity was perfect and I am pleased that my ice cubes were normal sized (since the builder installed a larger RO line from my island to the fridge). I just realized how much I was missing the RO tank pressure (which equates to faster filling of water jugs & cooking pots). I went back to Amazon and found this permeate pump which said it was the newer model that makes less noise. The unit arrived in about a week (no 2-day prime shipping available for it). I watched a YouTube video for installing it on a basic 5-stage RO and had it all hooked up in about 20 mins. I’m once again in RO bliss. The water pressure in the faucet just makes me smile...no more waiting a minute to fill a normal glass with water (OK it’s not literally a minute but felt that way to me). The noise is considerably less from the pump itself. I ended up buying some u-shaped plastic clamps (Amazon search: TmallTech Big Simple Clip Clamp 2.5" Bracket Reverse Osmosis RO Membrane Housing (Pack of 3)) that hold the permeate pump to one of the RO filters so the pump is not directly mounted to the cabinet wall (like it was at my previous house). Also, since I don’t have an air gap on this RO faucet, I have no additional noise from the faucet. If my house is silent, you still hear the pump cycling the water, but it’s minimal and it’s only until the tank is full. After that, it doesn’t cycle back on until water has been used from the tank. All in all, I missed the permeate pump benefits and will never have another RO system without one. I will also make sure I don’t get an RO with an air-gap faucet either. Hopefully this review helps people.

We actually have pretty decent tasting, clean water already. Absolutely no complaints on that one but some of the reports of what even very low-levels of some chemicals may be doing are enough to raise some concerns and this is decently priced so we decided to give it a go. Although installation was not too difficult, there were a few, fairly small issues that could have been smoother. Firstly, the instructions include no clearances or dimensions so the installer is left to measure and um-and-ah for themselves. We have a slightly awkward install as I decided to place it in the corner where there is some otherwise infrequently used space. There is a permanently installed shelf there. After a bit of backward-and-forwarding, I was able to ascertain that there was clearance for the tank and for changing the filters (with about 1/4" to spare). A mounting template would have been a very useful addition. Due to the confined space, I mounted one of the screws very slightly from where it needed to be and had to move it. The instructions are laid out like a brochure. Not terrible to work from but it means you have to hunt for the specifics sometimes. Other than the aforementioned dimensions and template, they're pretty complete though although it claimed a washer for the faucet that I didn't appear to have. It didn't seem to affect anything. You'll want to attach a fair amount of the pipes before you're crawling under your sink, especially if you have reduced access as I did. The top two filters are also probably best removed for the first part of the operation. They pop back in pretty easily. The faucet is a bit of a pain to install, especially with the small nut and that you can't attach the pipe before the faucet is installed (having a way to do that before was a godsend). I tried using the push-fit attachment first but that somehow seated wrong and was leaking. The plastic-olive alternative works fine though. A small, cheap angled wrench for tightening up the nut(s) would be a welcome addition to the kit. I did have a regular wrench but it wasn't ideal for the space. The short pipe to the leak-stop mechanism is just a bit too short. I had to mount the filters high because of the shelf and that means it doesn't quite reach the bottom. I bought some more pipe to give me that extra length but just a few more inches would have been nice. The water itself... To be honest, I can't taste much difference. It's good but, as mentioned, it tasted good anyway. I have noticed that flavored drinks seem to taste a bit better though. Maybe a hint less of a chlorine smell (though that wasn't really an issue anyway). But it's more about the health side of things anyway. It might be interesting to see the difference in TDS but I'm probably not going to bother. Oh, one other thing is that the shutoff exits to the right but my system is to the left. Not a big deal, just a little annoying. I couldn't see any way to switch it over. Edit: Having used for a few months, no complaints. There is a slight whine when running the faucet but no big deal. One thing that could have been included in the box would be replacement schedule labels. It's not hard to manage ourselves, of course but it would be a good way for the company to encourage filter replacements. An app might be an idea too for people who would use such a thing.

I've had a 3M RO for years in my home and really like it then decided to get a cheaper RO for my detached garage, so ordered this. Thoughts: I've not seen anything better packaged for shipment in my life. Fairly easy install with well illustrated, color coded, easy to read installation/owner's manual. Took me about 3 hours at slow pace. No leaks. Contents were decent quality. Nice touch providing extra o-rings, hose QDs, and extra filters. I flushed it four times then tasted. Perfectly clear. I think it provides a wholesome fullness, no taste, it's pretty good. And its pressure and flow is better than my 3M. My only surprise is the very slight dryness towards back of tongue after a cup, something I haven't experienced with my 3M setup. Filter replacements not as easy. More cumbersome than my 3M. However, I believe my softener is causing, contributing to this dryness, by removing most hardness before this RO. Nevertheless, I do like it, especially at existing price-point. Would buy again.

I purchased the 5 stage home drinking reverse system on March 1st, and it arrived at my north central Ohio home on March 6th. I was pleasantly surprised when I opened the box. The unit is a quality built unit, with a manifold that houses the 3 standard filters on the bottom, with the RO filter and final charcoal filter on the top, in the horizontal position. The unit was complete with fittings to connect it under the sink, and includes the sink faucet with a nice mounting washer that fit in an existing hole in my stainless steel sink. It even included the safety clips for all of the push to connect fittings that makes them nearly impossible to come apart if the clip is in place. I installed the system on Saturday, the 7th. If I were to mount this under the sink, as it was intended, I am sure that everything I would need would have been there, except maybe for a fitting to tie into the water line. The one supplied is for a different size line than the ones in my home. I installed the unit in the basement up in the floor joists. I hung the manifold by two screws into a floor joist, next to a beam, so if I ever finish the basement, I would not have too much hanging down. The tank was 11-1/2” diameter, and it would not lay above the beam as I had hoped, so I ripped down a 2X4 to 2-1/2” wide, and tied it onto the 9” floor joists with a couple of dry wall screws, and put a piece of plywood on it with some more drywall screws and laid the tank on the shelf, directly behind the manifold. I wanted this unit to supply water to my sink, my refrigerator, and my Keurig coffee pot. I tied into the water line, through an existing saddle valve that was used for water to the refrigerator. I ran the supply line, about 10’ to the RO unit, and fed it through a supplied valve. The plumbing was very easy and straight forward. I did add a permeate pump, which I also purchased from Amazon. It was the ERP1000-JG-S and it came with fittings, some tubing, and a mounting bracket which I attached to the manifold on the left side by drilling two holes. I probably would not have needed the pump as I have 70psi water pressure, but my water is from a rural water company, and is fairly expensive and I didn’t want to put too much down the drain so the permeate pump would waste much less as it relieve the backpressure the RO water puts out as it tries to fill the tank and uses the waste brine as the pumping power source. I stepped the ¼” output line to 3/8” and ran it through a “T” to branch over to the sink, and back to the refrigerator and coffee maker. Near that end, I stepped it back down to ¼” to go to those appliances. This allowed me to make a longer run with less pressure loss. I also purchased the HM Digital TDS-EZ Water Quality TDS Tester and it arrived before the RO system, so I tested the water and it was 172ppm Total dissolved solids. I took the tester to work, and compared it to a similar unit we had at work as we have a large, commercial RO unit there that produces up to 600 gallons a day. The low cost HM Digital read identical to the high end unit we had at work. On my first batch of RO water, I tested it and it was at 19ppm TDS, which is a great number considering, the first tank gets dumped as it had impurities in it from the coating on the RO membrane and the other filters. After two weeks, the water quality has settled in at about 15ppm TDS. The water from this unit tastes great, with absolutely no odor, and is of very high quality. I ran around for a day, testing every brand of bottled water I could get my hands on with the HM Digital TDS meter, and found that the water through the RO system is as good as, and better than most bottled water you buy. I doubt that you will find a better unit than this for twice the price. I looked at the big box stores, and most of the RO systems they sold used custom filters that they rip you off for. The filters in this unit can be purchased at a lot of different vendors, and the four extra filters they supply makes this an even better value. They do not supply an extra RO membrane, but that is usually rated to last up to 24 months so it won’t need to be replaced until after the extra filters have been exhausted. Plus, if you want a higher capacity unit, you can purchase a higher capacity RO membrane, which I may do when I wear this one out after a couple of years, but for right now, it supplies all the clean water I need. One last note, if you are looking for a Keurig coffee maker with a water supply, you may not find it. I added a Okeler Adjustable Mini Plastic Float Valve which I also purchased from Amazon to mine as I got tired of filling it everyday.

Was considering the tabletop version of this filter, but for around the same price I was able to get this model with a tank and extra filters, so I went for it. Easy installation and there are plenty of videos online. My only complaint is the filter housings were real rough to get to tighten. First attempt there were immediately leaks. Maybe they need some water on the threading to help screw them on better? The installation videos on youtube made it look very simple- I thought I was about to snap the wrench that came with the system. The tanks seems to hold around 2 gallons of water, which is practical for daily use. I mostly will use RO water for home brewing beer and making coffee so I'm not going through gallons at a time unless I'm filling water jugs. All the hosing seems to be holding up well and installation was easy. A cheap TDS meter shows around 250 TDS going in and about 10 TDS after the system, but that number was higher before and seems to be slowly dropping over the days.

Express Water System 5 Review Overall, a fairly decent system. My first unit lasted around 4 years before it started leaking—couldn’t fix it despite replacing both O-rings and tightening multiple times. Eventually gave up and bought a second unit. Later did a closer check on the old system and found a crack on the GAC stage—glad I didn’t waste more money trying to fix it, though it’s surprising it cracked under just moderate water pressure. For the price (especially with the included replacement filters), I think it’s reasonable to replace the whole unit every 3–4 years. Total cost of ownership feels fair.

I owned an iSpring 5-stage system for about 6 years. I liked it, but it eventually developed a micro-leak inside the cover, so it was time for a replacement. I decided to try the Express Water RO5DX, and honestly, I believe this system is superior to the iSpring in almost every way. The Good: -Value: It feels like an improved version of the iSpring but for over $100 less. -Installation: It came mostly assembled with color-coded plugs and even had Teflon tape pre-applied on many connections. The instructions are diagram-heavy and very easy to follow. It includes all the necessary tools. -The Leak Stop Valve: This is an incredible piece of engineering. It’s a mechanical valve (uses a compressed sponge that expands when wet) to shut off water if a leak is detected. After my experience with my old system leaking, this gives me total peace of mind. (iSpring had some battery powered detector that just made a noise.) This one actually stops the leak if it detects it by shutting off the value. I am so shocked about this. Peace of mind if something terrible happens and i'm not around. -Design: The filter housings are labeled, which will make future replacements a breeze. The connectors feel more solid than my old system. The "Okay": -The Faucet: It’s a little uglier than the one that came with my iSpring, but it works fine. -Drain Saddle: While nicer than the iSpring one, it was still a bit small for my drain pipe. Installation Tips for Buyers: -Drain Saddle Seal: To get a tight seal on my drain pipe, I used some sticky putty (blue tack) around the hole before tightening the saddle. It created a perfect seal. -Tank Pressure: Mine arrived at 4psi. I used an electric tire inflator to bring it up to the recommended 8psi. -Flush the Carbon: Before connecting everything fully, I used extra tubing to flush the pre-carbon filter into a bucket/shower to clear the black carbon dust. I did the same for the post-carbon filter so it wouldn't get into the tank. -Tubing: I cut the tubes shorter to reduce clutter under the sink—easy to do if you are familiar with these systems. Overall, replacement filters are reasonably priced and the water tastes amazing. I couldn't be happier with the switch. **This review is done just after install, I will update review if things change, Initially I am EXTREMELY impressed and happy with my purchase**

Fácil de entender. Fácil de ensamblar. Recomiendo lubricar las juntas con lubricante de silicona grado alimenticio antes de ensamblar. Ayuda enormemente y extiende la vida de los empaques. La instalación a la toma de agua es el paso crítico porque depende de la tubería. Desde ahí, todo muy sencillo. Claro. Excelente la válvula de autostop. Tener cuidado porque si le caen unas gotas de agua ya instalada, la almohadilla es muy sensible y se expande. La calidad del agua muy buen. El medidor (no incluido) marca 1ppm.

Works as Advertised! Here in Calgary, the Lefties decided we needed fluoride in our water. I don’t like more fluoride as fluoride is a naturally occurring substance in River water. This takes care of fluoride and any other contaminants. We were using a zero pitcher for our drinking water. Water is as good or better than that and our zero water filters only lasted a month! Water tastes fantastic too! With system running water to our fridge we have 5 filters cleaning water after the osmosis filter. Installation was easy. Have been running for six months and just coming up on first filter change. Damn dog likes water so much she won’t drink anything else! Won’t be disappointed .

Muy buen purificador de Agua, el agua sabe muy rica además de que viene con un set de repuestos, lo unico es que compren la bomba de presión por que en México es muy baja la presión y no funciona agréguenle mínimo unos $2500 pesos mas de la bomba, yo la compré en home depot por rapidez me costó $3300 pero en amazón está mas barata, su instalación es muy sencilla. el instructivo está en inglés pero hay videos de Youtube, recuerden reutilizar el agua que sale de desperdicio, sale limpia, pueden instalar un bote de recolecta del agua o mandarla de nuevo al aljibe.
