RTW5AK-UV Reverse Osmosis Water Filter System with Alkaline Remineralization & UV Protection, 7-Stage Under Sink RO Water Filtration System with 3 Extra Pre-Filters

Wow Unbelievable. after 4 years - update. 2024. I called and talked with Nick again who provided the VERY BEST customer service I have ever gotten in my entire life. He answered the phone and within minutes my small install problem was solved and he is sending the part I needed at no charge. If you are looking for the best RO system, at the best price, you do not need to look any further. I did extensive research and found the Puredrop RO system to be the best overall. It has the best price, wonderful support, and is a very well-made quality system. ISPRING VS PUREDROP Puredrop is the same company that makes ISpring, which is also a very nice RO system. I was not sure if I should buy the Puredrop RO system compared the ISpring RO system, so I called support and asked the difference. I spoke with both Nick and Don who provided all the answers to my questions so that I could make an educated decision. ISpring RO t is more money, but you get more for your money: Larger Tank, a Clear 1st Stage tank, and a better faucet. In my case, it is just me and my wife, and I do not need a larger tank and I have a faucet from owning other RO systems and I would only be giving up the clear tank with the Puredrop System. CLEAR 1st STAGE TANK If you change your filters on time, there really is no reason to see inside the first stage. If you are forgetful, it may be a good idea to get the Ispring system with the clear first stage tank. FILTERS AND MEMBRANE I had other RO systems in the past, and the biggest issue I have found was the cost to replace the filters-especially the membrane, which can be as high as $40 for some name brands—especially if you have to have the check value built into the membrane. The Puredrop RO has the check valve as a separate component in the system, which eliminates having to buy a membrane one with a built-in check valve. PLUS, I love it that PureDrop provides an extra set of filters for the next time the filters need to be changed. After researching the filters, I found that I can buy generic filters for a lot less and if I wanted the Puredrop brand, it was not that much more. INSTALLATION AND SMALLER TANK The Puredrop RO system, which was easy to install with color coded water lines. So far everything is working fine and I really like the small compact tank, which gives me a lot more room for storage under the sink. There is no reason that I can see to have the larger tank for a family of two. CONCLUSION The Puredrop has been installed for a week when I wrote this review. I suspect that will not have any issues, but even if I do, I know that I can always call support: Nick or Don, and they will for sure take care of any issues I have for years to come.

Easy to install not a problem with leakage at all , I personally drained my storage tanks twice then connected my uv up and drained a third time water tastes great like rain water only way I can explain it , the design makes it pretty self explanatory and is a good quality product I’d recommend it especially if your on well water and share a well that doesn’t get much attention . Thank You !

We bought this during the latest prime day sale and we are happy with it. The installation went fine, though I did end up watching a couple videos along with using the manual to be sure I had things right. There were no leaks on startup despite there being at least 20 connections that could have a water leak. Most of those already come connected by the factory and you don't have to do them but they are still a possible leak source. I read a comment by a plumber that recommended putting something under the tank as the materials making up its valve are more likely to leak than others. This particular tank is smaller than most under sink systems so is better if it's tight under there. If you have a larger household you may want a bigger tank but I honestly think it's sufficient for most families and it is always refilling when water is depleted. My countertop had a hole already that was occupied by a soap dispenser, so I repurposed it for the included filtered water faucet and we fill a nice-looking dish soap dispenser that sits next to the sink now instead. Drilling the hole in the PVC pipe was much easier than I feared. Make sure it is done above the trap and the hole is the correct diameter. I purchased a digital total dissolved solids (TDS) device and the filtered water has been measuring 2 and 3 TDS, which is very good. The water tastes good to me despite there being no minerals and feels smooth in the mouth. It's nice knowing the water is pretty much as clean and pure as it possibly can be for us and our pets. The extra 3 filters included pushes out the filter buying time to 1 year. Reccomended.

Great 5 stage RO, I would definitely recommend , I don’t have to buy water from the stores anymore.

Super easy to install. I'm very satisfied with mine.

I honestly wish I had something bad to say about this system. But I got it at a really good price (127$) and it’s working flawlessly. It was pretty easy to set up. The instructions were a little confusing. But overall very easy set up and it works pretty good. I also like that it comes with replacement filters. Got my water down to about 20 ppm but don’t quote me on that because I can’t guarantee the accuracy of my meters ha ha. It fits under the sink nicely. I don’t use it for drinking water, but I do use it for my humidifier and I haven’t seen any residue buildup in the room since I’ve switched to RO.

Our "new" house had awful tasting water. The water was cloudy straight from the tap. Cold or hot, it was murky and I did not like the taste of it. When I found the reverse osmosis system with five filters from Puredrop I was very excited. It took a full day for my husband to install it. It kept leaking, and they warn you that it may leak. So he just kept tightening the canisters whenever they leaked. The leaks were not the systems fault, he had not tightened them very tight from the beginning because it is plastic and he did not want to over tighten them. My first cup of water was divine. Everything I had hoped water would taste like again. It seems like a small thing, water out of your tap, until it is foul and you will not drink it. No more bottled water and I can drink as much as I want again. I am very happy with this system. Everything tastes better. Coffee, tea, and I even noticed my pooch drinking more water. I am very pleased with the system. I included a photo of the system with the color coded tubes attached already. It made it very easy to install because everything is color coded. Even the clips that go over the connectors are color coded. The system included specialty wrenches for the canisters, the wrenches in my picture are my husbands who decided to go ahead and upgrade a couple of our pipes while he was under the sink. I am also pleased that PureDrop sent extra/replacement gaskets for the system. I bought extra filters for later, but the system I bought also came with an extra set. I am telling everyone about this in hopes they can have no fluoride/chlorine water. I plan on buying another system for my brother as a gift. Four-year Update: Costumer service is great except the product is awful. Three tanks later, they continually rupture, we bought a counter version. Something is wrong with the design of the tank, and it continues to rupture the bladder inside. After the last time they sent us a replacement tank, it was three days until it ruptured as well. One of the filters had a slow leak. We found out when the cabinet floor caved in, and we heard the tank fall over. We bought the system thinking it would be no hassle, but it turned into huge hassles. The countertop purification we bought is easy to use and we can keep an eye on it, plus we never have to call and get new parts and install them. Good luck, hope this helps.

Overall I am happy with this product but it comes with a few caveats. We have been using this for about 3 years and now my family refuses to drink water from any other source, taste is a definite strong point for this product. On the flip side we had a small leak problem in the beginning due to a faulty O-ring, not a big deal but local hardware stores did not have a similarly sized replacement and support twice sent me the wrong O-ring replacement. I ended up giving up and repairing the O-ring myself and it worked for several years after that. I then had an instance when the bottom of the housing was "blown out" by what was probably a spike in my city water pressure. After discussing with support they informed me there was an additional part needed to prevent this happening. Fortunately for me I was standing in the kitchen when this happened otherwise the damage to our kitchen would have been catastrophic. That being said support in the second instance was phenomenal, they immediately sent me both a replacement set up as well as the part needed to regulate the city water pressure spikes. This really should be included with the original product or it should have been designed to accommodate this as these are intended to be installed in homes. Nick with support was fantastic, knowledgeable about my issue and he happily remedied it immediately. **Update 2023 Unfortunately we had another leak due to a crack in the filter housing in spite of the water pressure regulator. ISpring and Nick again provided fantastic support immediately sending me a new pressure regulator as well as a complete new unit. I am disappointed in the several leaks we have had but this may be a faulty unit seeing the number of leaks over the years. The phenomenal customer support is why I remain a customer and if necessary will purchase from them again in the future.

As a plumber that’s installed hundreds of r/o systems, install is a breeze. Instead of the 5 stage I get from plumbing supplier I figured I’d try this for our new house. Other system had 200.00 filter change costs. Looks pretty much like a Hero system. Can’t knock it for the smaller pressure tank or short lengths of tubing that I didn’t use since I put it in mech room instead of under sink and used 1/2” pex for fridge and sink faucet runs. Good pressure at 30’ away. No leaks from system. A lil tip… get an oring that fits inside the tank valve instead of trying to Teflon tape tank threads and risk over tightening it.

Excellent system, all you need is there, water quality is great.

So Let me start off by saying I have been drinking RO water all my life growing up... So when I moved to this country I spent the first few years using Brita's and ZeroWater's pitcher filters but they were not up to the mark for me (I have sensitivity to something in Tap Water that these pitcher filters just would not help with). So I finally decided to give into an RO. This RO was easy to install !! No Leaks (and this was my first time ever doing plumbing related DIY, Although you have to follow instructions to the T). I didn't install the faucet that came bundled because I didn't want to drill a hole in the kitchen sink so I bought a new 3-way faucet for my kitchen which comes with a RO connection in-built. The RO works good. The taste seemed to get better over time... I did purchase and install the extra Alkaline Mineral Cartridge to this RO (The one in the Orange/Red in the picture) to make the water less acidic which RO's tend to do by stripping out the minerals. All in all a satisfactory purchase and the Support(My conversation over Email with NICK) was pretty quick to answer any questions/rectify any issues if you find them.

It works it takes all the time out and we have a lot problem is ultra light doesn't come on and it leaks on stage 3 looks like they're going to make it right though

I highly recommend the company and its products. They also have great support and can help you with any issues very quickly.
