CuZn Under Sink Water Filter for Sink Faucet, 5 Year Filter Life, NSF/ANSI 42 & 372 Certified, Reduces PFAs, PFOS, Lead, Chlorine, Inline Faucet Connection, Improves Tap Water Taste

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.

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.

great filter and easy DIY. Water tastes great. Comes with water testing kits but I haven’t used it yet.

Easy install, makes a noticeable difference in water taste (municipal water; idk how it would do for well water). Three or four people in the house noticed when the filter no longer worked, which made it easy to know when it needed replacing. The first one lasted 4 years, which is great. I know the description says 5 years, but we do a lot of cooking and a good amount of entertaining, and therefore a lot of cleaning, too; so we probably use more water than average. I never really expected it to last 5 years; I'm very happy with 4 years, and I'm sure I'll buy another one (my third). For the cost, it works out to about $35/year, which is comparable to what I pay for filters for the refrigerator water dispenser. And a whole lot more water runs through this filter than through the fridge! FWIW I have this on the cold water line only, which does not filter the hot water from the hot water tank, nor does it filter the water to the dishwasher. But it does filter the water to the under sink instant hot water tank for the separate hot water dispenser. Because the instant hot water tap is mostly for making tea and other drinks, having this filter is almost essential. We added one at work, too, because of the instant hot water tap there. Probably good to know that this is for taste. It is not a purifier or a softener. If you have a purifier or a softener, this could pair with those easily, if you want go change the taste. Also good to know that it did not seem to reduce the water pressure at all. It uses the same size and type of hoses as most faucets, so it's easy to hook up. It stands up behind my garbage disposal, do it's out of the way.

Personally, I can't taste the difference between ditch water and rainwater, but my wife is Canadian and has always lamented the poor taste/quality of tap water here in Perth. This unit gets her tick of approval for water quality, and it gets my tick of approval for value for money, ease of install (did it myself with the excellent instructions provided), and customer service from the company. These guys really care about providing you with a quality water filtration system and a hassle-free experience. Gotta love that.

Great filter. Easy to install. 5 year filter. I no longer smell or taste chlorine and other chemicals in our city water. We used to use bottle water, including for our dogs, but I got fed up with that and found this solution. It's perfect!

El filtro leí que es una de las mejores opciones qué hay. Pero llevo dos meses buscando un conector que me sirva para conectarlo al tubo de plástico de 1/4 (tipo filtro de agua) que va a mi llave de sobretarja exclusiva para agua purificada. Para conectarlo a una llave de cocina normal, no hay problema. Las mangueras de 3/8 funcionan Perfecto. Pero en MEXICO no he encontrado el conector necesario para un tubo

Based in Singapore, I was not sure if I would be able to successfully use this given the differences in plumbing standards between the United States and Singapore. Nevertheless, I took a leap of faith, and decided to give it a go. After trying to find the fittings unsuccessfully, I reached out to the CUZN customer service and it was a lifesaver. CUZN sent over the required fittings to me and provided the plumbing schematics, and with some additional hardware bought from the local store, I was able to get it working. Thanks!

I'd been using jug filtration systems for many years and after using the CuZn system now for a couple of weeks I am wondering why. After you factor in a jug, replacement filters over 5 years based on a 3 month replacement cycle, taxes etc. you are around $150 TCO. With this system you are around $180 TCO but no need to refill jugs and wait for it to filter, it's right out of the tap, for $30 difference that not a lot pay for the convenience since this lasts for 5 years. The install is so easy and comes with everything you need. You do need your own wrench though. Suggestion to the manufacturer to include a mini wrench like IKEA does? Anyhow, on to the most important thing, how does the water taste since that is where you really find the value in this system. For my family, we love it. We compared it to the jug filtered water and could really notice the things left behind in the jug filtered as opposed to the CuZn system, no after taste at all, super clean and crisp. Initially you will see cloudiness in the water as the filter primes but that passes very quickly and you get a great tasting glass of cool H20. I highly recommend this product to anyone interested in a water filtrations system.
