WINGSOL Under Sink Water Filter NSF/ANSI 42, Reduce 99.99% Chlorine, PFAS, PFOA/PFOS, Bad Taste & Odor, Sediment, Quick Change, Life Indication, 6K-Gallon Water Filtration System

This is not our first filter system. We used the 3M Filtrete 3US-MAX-S01 filter system for several years. It became increasingly difficult to find replacement filters which also became increasingly more expensive. I decided to try the Wingsol WS-US-002. Because we recently replaced our kitchen sink faucet with a touchless faucet which limits the flow rate to about 2 gallons/minute, the 3M filter became an annoying problem because its flow rate dropped even more.Installation of the Wingsol went without any problems. I do have some experience with plumbing jobs so whenever I have to screw metal hose connectors onto plastic threads (the hose connectors of the Wingsol filter), I use teflon tape. Not as much as I would use on standard NPT thread (which usually is tapered), but around 3 to 4 turns. Just enough to make the connection between the metal connector and the plastic thread more snug. And don't overtighten! Really - just gentle tight. Grab the wrench at the top of its head, not at the end of it. That way you feel it much more that you are getting tight.Plan your installation and measure. In US kitchens, the rear wall of the cabinet usually is flimsy. And the filter combo does have some weight to it. I decided to mount on the right inner wall of the cabinet. For me that meant that the hose which goes from the water valve to the filter was long enough. Had to get a 1ft extension hose to the faucet (which I already had).I mounted the PC filter 180 degrees rotated so that I can look at the filter indicator when it is installed. I don't need to see the "front" label - I know it's the PC filter. See the attached picture.After installation was completed, I tested. Everything was tight, no leaks. And the flow rate is phenomenal! Basically no difference between full cold (filtered) and full hot (unfiltered). Very happy with this setup. Water tastes good, no complaints here.I was wondering about the filter life of stage 2 - the instructions say "Replace CB filter after 3-6 months or when water starts to taste bad". Our water does not taste bad without a filter. So I contacted the seller about getting some clarification. Seller reacted very quickly. After some exchanges of messages I learned that of course the filter will become less efficient over time (I expected that anyway) and that it may reach a breaking point. I asked the seller about my idea of running some simple chlorine/pH/alkalinity test every month (filtered and unfiltered) to maybe get an idea about when the filter gets bad. Seller agreed to that idea and that's what I will do. So ... if I can discover that filter performance really starts to go down after, e.g. 5 months, I will replace every 4 months to be on the safe side. Just want to get to a replacement interval that fits my specific water quality and consumption.Conclusion: easy install, no problems with the quality, great customer support, I call that a good deal!

I recently installed the Wingsol under sink water filter, and I am thoroughly impressed with its performance. The installation process was straightforward, even for someone like me who isn't particularly handy. Within minutes I had fresh clean water flowing from my top. The taste difference is remarkable, Chris and pure, without the slightest hint of chlorine or other unpleasant flavors. It's been a great solution for our family, offering Peace of mind knowing we're drinking contaminant free water. I also appreciate how compact it is, saving space under the sink while still delivering high quality filtration. The filter replacements are reasonably priced to swap out, making maintenance hassle free. Overall the wings all under the sink filter is a fantastic investment for anyone trying to improve their homes water quality. Highly recommend!

Depending on how much room you have under the sink, it should be easy to install. I have a high flow faucet and the filter doesn't have a problem keeping up. The water tastes better and is clearer than any bottled or other types of filtered water I've ever had. I have never had a leak, and depending on how clean your tap water already is depends on how quickly you will need to change the filter which is very easy to do.

The media could not be loaded. Before purchase, I checked into how this unit is tested and built. Every answer from the manufacturer indicates the filter manufacturing is done after completion of necessary engineering process. That includes the necessary certification and water hammer test. Some folks commented on my inquiry of the unit hammer test as unimportant. They forget most liquids are incompressible and the constant open/close of water faucet can over time cause leakage and even burst inside this filter. The most unpleasant thing after installation is to see a flooding in my kitchen.The filter arrived with two connectors which allow half-inch or 3/8" connection. My picture shows how the 3/8" connection should be made for my kitchen faucet. For 1/2", exchange the two connector positions in the picture. The overall installation took less than 10 minutes including flushing the filter for 3+ minutes before taste test. It is simple and straight-forward as expected. You can see in my short video that there is no INITIAL cold water pressure drop after installation. Comparing the taste before and after installation, this filter surely takes away the chlorine taste. About how well this filter can perform in other areas, most test kits cannot do a good job and I also have no reason to suspect heavy metal poisoning in the Chicago Cook County suburb area. So I will not spend time and effort in this area.I also tested how to replace the inside cartridge as the manufacturer said. It is a simple twist to unlock the housing from the top cap, then use the enclosed wrench to release the cartridge before placing a new one inside the housing. However I turned off the water supply when doing my test. Their claim is that this is not necessary but I do not want to take that risk. And I won't be surprised a strap wrench is necessary for cartridge replacement after some period of use.The main reason I cannot give an initial 5-star rating is due to the 8K gallon filter life misinformation found on the Amazon web description. As you can see on the filter label, it clearly states maximum filter life is 2K gallon. 8K is very different from 2K. My area has water from the nearby Lake Michigan water treatment center so they are very good city water. My expectation is that this filter should last at least six months before replacement. I will update this review later on the durability aspect of this filter. My initial impression is that I would recommend this filter based on its price and quality.

The media could not be loaded. Very easy to install and has worked well. You can taste the difference. I think it depends on your water use as to how long it lasts too because it says 3 months but it's been about 5 before I'm thinking it might be time to replace.
