Under Sink Water Filter for Sink Faucet by CuZn, 5 Year Filtration Life, Reduces PFAs, PFOS, Lead, Chlorine, Improves Taste of Tap Water with NSF/ANSI 42 & 372 Certified High Performance

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.

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

The unit installed easily in minutes using the included braided metal supply line with no additional adapters needed (although the company's guaranteed installation policy promises to supply anything you may need to make it fit) and it works exactly as advertised. The filter is a stand-alone unit that sits solidly under the sink against the back wall and requires no mounting brackets to hold it in place. The water runs clear and tastes fine, reminding me a little of soft water, although this line does not run through our whole-house water softener. My wife and I drink Ice Mountain bottled water exclusively, but we use this filtered kitchen water for coffee, cooking, and for our three dogs and three cats. We live in Speedway, Indiana, and the city’s water quality has been borderline in its annual testing over the last few years. So, we felt we needed to do something to protect ourselves and the fur babies. We have a Delta Lenta touch-activated single-handle faucet with pull-down sprayer, so a faucet-mounted filter is not an option for this location. After thorough research, we chose the CuZn product over several other highly rated brands with replaceable filters. Based on the online reviews, their customers have been extremely satisfied with the ease of installation, product performance, and the level of service and support. We also liked that their product is made in America. The filter has a 5-year pro-rated replacement policy for the unit and when the 5 years is up, you can just easily remove and replace it with a new unit. The per year cost is less than other units that require their filter cartridges to be replaced on a regular basis. One of the reasons I chose it over the others was its high GPM rating, and I’m happy to say there was no noticeable reduction in the waterflow after installation. Another reason I chose it was the wide range of contaminants it filters. CuZn included 5 chlorine test strips with the product under the theory that Chlorine is the contaminant most commonly present in city water and is a good indicator of overall filter performance. The first test 24 hours in came back clear, so I assume it is doing its job. However, I may run a more extensive water quality test on it at some point to satisfy any curiosity I might have about its rated performance. Like many on the market, this unit is not a TDS (Totally Dissolved Solids) filter. But since these include beneficial minerals found in spring water generally thought to be essential for good health, you probably don't want them to be removed unless you're trying to achieve totally pure H20 for some reason. If you are, you should opt for distilled water. Bottom line: It seems to be a solidly built, high-quality product and we’re happy with our choice.

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!

Good filter. I works for its purpose
