Under Sink Water Filter for Sink Faucet by CuZn 5 Year Filtration Life Reduces PFAs PFOS Lead Chlorine

Just bought our second one after 5 years. Definitely takes the chlorine taste out of water. Very easy to install, worked fantastic for the 5 years (maybe a little longer), no issues at all. I reckon I’ll keep buying these every 5 years Read more

Just reordered. The first filter lasted 4 years and 4 months (it's a decently high volume household, and our water is overly softened, courtesy of the HOA). The salt taste came back just now. Otherwise, this filter has been fantastic. Good flow rate, doesn't get the off taste and pH issues from RO water. Hookup takes less than 10 minutes. Also this somehow avoided inflation? Since my previous purchase (4+ years ago) the total cost to reorder now (after tax) went up by a total of 8 cents. Read more

I feel extremely excited writing this review. I ordered this water filter system after spending many hours browsing for a water filter that was reasonably priced and offered the best filtration system for a clean supply of water. This filter was the only one in our search that offered exceptional value for our money. Not only did it not have any requirement for periodic change of filters which most other systems require, but it also had the most thorough filtration process making the water extremely clean and pure. And another amazing feature of this darling was that it was so easy to install and the system was not a bulky item. This beautiful system also offered a life of 5 years. No other filtration system we saw offered this for such an amazing price. We have been using this filter for over a month now, and we are the happiest people. We have tested the water using testing strips and the results are always positive for pureness. We use the water for all kitchen purposes with peace of mind and the water tastes crisp. This system is saving us 50 dollars a week which we used to spend buying water cans from the store. Not to forget to mention the amount of nano plastics we were injestic from these plastics cans which this system has now put an end to. This review will not be complete without mentioning the extraordinary customer service that the owners of this system provide. The team is exceptional and they are with us till the installation is complete and running smoothly. Every step of the installation process they offered guidance and shipped the required installation accessories free of charge, including a small filter system to remove TDS. They were readily available for troubleshooting and followup. And they promise replacement if we encounter any problems during the 5 year period. No company offers such a sweet deal and keeps cutomer first. Thank you Cuzn Family. We are very happy that we became part of the Cuzn family. Extremely happy customer for life. Read more

I don't have a single bad thing to say about this filter. It's super well made, super easy to install and the water tastes as good as my old triple stage reverse osmosis unit. After a pretty exhaustive search, I don't think you can do better in this price range. Construction- Really well built. Heavy and sturdy. They did a great job. It looks like the person or people that made this really cared about the kind of water you are going to drink as opposed to how to cost effectively deliver a decent water filter. Still, at $119.00 this is great and in person, it looks/feels a lot more well built than it does online. Installation- First off I love how this can just stand in the corner and not get in the way of anything. I've tried a few other filters and they took more work to get them out of the way. The hose it came with didn't look cheap and matched the hose I already have that attaches to the faucet. Also where you mount the existing hose to the sink is built into the filter. So many other under the sink filters have another hose that connects with a male to male adapter. This reduces clutter and makes it really easy to install. Size- It's pretty big and it's a lot more filter than you would think when looking at the pics. Make sure you know how much room you have under your sink. Still, I had a lot of room left before it would hit the top. There is a lot of filtration going on. Water Flow- It's almost unnoticeable after it's installed. My wife or nanny didn't even notice the difference. I was really worried about an under the sink filter because I knew any good filter would probably not filter water as well if it had high flow. I tried some, like the Woder 10K and the Hansing 13k. They weren't bad but neither flowed like this. My main concern with the faucet was too much reduced cold water flow would cause the hot water to be too hot but this is really close. Water Taste- Not only does this flow well the water tastes really good. The place we moved to couldn't house our Reverse Osmosis unit so I had a lot of trouble finding something comparable. Luckily we now have much better water so I didn't need as much filtration to get the same taste. It blew away the Hansing 13K and is noticeably better than the Woder 10k. It also blew doors on some sink top filters I tried as well like the CleanWater4Less and Apex Countertop Waterfilter. The water is clean and crisp. Before this the water from the other filters didn't taste that great and sometimes made my stomach a little off. Nothing bad but just wasn't settled like it use to be. Now the Woder 10k wasn't bad and I could have probably lived with it but the CuZn was so much better. After being unsatisfied with all these highly rated countertop and under sink filters I finally found the right one. It tastes like bottled water and I'm so happy I took the time to write up this review. I feel like I owe it to this company for standing so far out above the competition. Hopefully, it will help others in a similar situation as myself. I'm buying their refrigerator line filter next and my incredibly frustrating search for a good water filter is finally over. Thanks CuZn and you make a really great product. I don't think there is a better under the sink filter in this price range or even a good bit higher that can do what the CuZn does. Read more
