WaterChef Premium Under-Sink Water Filtration System U9000 with Intelligent Monitor & Designer Faucet (Chrome) | NSF/ANSI Certified 78 Contaminants | 1,000-Gallons | Stainless Steel | Made in USA

1 year after my purchase, I did my first filter change. While going through the very simple exercise of changing the filter, I realized how pleased and happy I still am with this product and the customer care experience.I ordered the replacement filter through Amazon Prime which many of you know is the easiest and the ultimate in high speed convenient shopping and high customer service standards, but that's Amazon. It's from the time I received the filter two days later that I was realizing how good the WaterChef experience is for customers.First, the outer packaging was high quality, efficient, and even aesthetically pleasing to the eye (not a requirement by any means for a water filter, but it does add to the overall "quality experience" of owning this water system). It securely holds and protects the filter, yet it's easy to open.Once you open the box, you see a very simple, well-written and easy to follow instruction leaflet including diagrams which includes everything I needed to know to exchange the filter properly. They took the time and effort needed to write the instructions in a properly helpful and clear manner. There is also a very clearly-written separate leaflet telling you exactly how to contact WaterChef if you have any problems or questions.Then you see the water filter, which is securely clear-plastic wrapped to ensure a sanitary product.It was at this point that I realized they ALSO include a replacement battery preloaded in a battery tray which you instantly can swap out with the old battery (this battery powers the filter life indicator). I had totally forgotten about needing to replace this battery so the fact that they include it with the replacement filter was so convenient and great (who has time to remember or worry about these trivial little details these days?).The way they designed even the battery compartment shows you how thoughtfully they designed this system for maximum convenience and low maintenance. The small watch battery comes preloaded in a tiny "tray" which sticks out from the water flow monitoring unit a little bit so you can easy grasp it and pull it out in one second, then swap in the new preloaded battery tray in another second. No need to fumble around with a tiny watch battery while hunched down under your sink trying to remember (from a year ago) where and which way to insert the tiny battery into the water flow monitor unit.The above may easily be overlooked as a just a minor detail, but to me I really enjoyed that thoughtful design nod to the customer. I felt they truly want my experience to be excellent, and that they care about making sure I am very pleased with their product. Such a refreshing feeling in today's consumer world.Then while changing the filter and washing out the filter housing, I realized I had forgotten how heavy the housing is due to the quality and durable construction. I also noticed how everything inside the housing was so smooth with basically no seams or creases where debris or grime could get stuck inside which would be very unappealing. It was a breeze to wash it out thoroughly.The clamping mechanism to secure the lid of the housing to the body is very robust and thoughtfully designed for maximum ease and convenience without sacrificing function and effectiveness.And swapping out the filter was simply unscrewing the old filter and screwing in the new filter. The instructions even thoughtfully tell you how to determine how tight to screw in the filter without risking damage to the expensive (but high quality) filter. Nice.Afterwards, the water filter unit was gleaming and shining exactly like brand new! I feel like this water filter system is going to last me a very long, long time and knowing that changing the water filter each year is so simple, easy and convenient makes me a very happy, satisfied customer.I did think this filter system was expensive when I first bought it, but now after experiencing their quality, durability and service, I realized the cost was well worth it. I really hate buying junk that ends up wasting my time, especially expensive junk. But this product pleasantly surprised me...enough to inspire me to write this review. It really is like the "Lexus" of water filter systems. The best part? I like the taste of this filtered water over bottled water. Awesome.

I had the exact same issue as another customer who posted a similar review here. The main water valve for the house had to be turned off because of some maintenance. When it was turned back on, all other faucets in the house were working fine except the water filter which started leaking under the cabinet. Luckily I heard the sound of water leaking and threw some rags to soak up the water and put a bucket to collect the water. It did cause some damage under the sink cabinet. Mind it, it was a newly remodeled kitchen! Bad decision to buy this product. I have put this filter in a big bucket permanently under the sink in order to prevent any future water leak damage (should anything like that happen again)

The media could not be loaded. This water filter is really easy to install. Granted, I already had a hole in my sink for it so I can't really speak on drilling the hole, but nonetheless. The instructions are very clear and I highly suggest you read them before you start the installation. The parts were very easy to put together and didn't leak at all. They all felt like great quality partsThe water itself tastes really good, although on the first try it was a little cloudy. It did clear up in the glass afterwards. Not too sure what it is, but I'm assuming it has to run a bit more than the 15 minutes recommended in the manual.I'll try to update this review after my first filter change. But so far I'm very impressed with this, especially for being able to grab it on Prime DayUpdate 10/26/23:The water is absolutely crystal clear and tastes amazing. Can't recommend it enough. I'll update this after my 1st filter changeUpdate 11/02/24:Still going strong! Filter hasn't needed a change yet. Absolutely awesome a year in

Installed the unit for less than a week. Happy so far with the performance. it is a quality product. The faucet ends at a vertical rather than an outward bend which would have projected the water stream farther out. In our case, because the faucet opening is set back, the water stream is a little too close to the sink wall for putting a cup down on the sink under the faucet to collect the water. Minor inconvenience.The wire for the indicator ring gets into the way of the center metal tubing and needs to be filed down for the ring to fit evenly around the tubing. Otherwise, the gap where the wire abuts the tubing will have a wider gap. Minor cosmetics.

Overall excellent. Installation was straightforward with basic knowledge of hot/cold turn off. Drilling hole thru granite was long(40 minutes) and tedious, but doable with correct equipment. Used Dewalt corded drill and Milwaukee 5/8 dry diamond bit. Flow thru provided faucet is steady and adequate. Taste of water is definitely better than city tap. I cannot tell difference in smell.I would definitely purchase again. Solid made product.FYI. Reason purchased was due to water dispenser failure on 2 expensive refrigerators

While the filtered water does its job, the connectors are weak and caused a leak.Be aware that the water pipe connectors (from the water line to the filter sensor, and from the filter sensor to the filter and back) are not well designed. They cause leaks. We had a recent situation where one of the connectors (from the sensor to the filter) popped out because of a slight increase in water pressure (resulting from some water main work). This caused a big leak in the cabinet under the sink and eventually seeped under our laminate wood which is completely warped.I am surprised that such a good quality filter comes with such a poor connector. I would have preferred a pipe connectors which had to be screwed on rather than one which are pushed in.I would not recommend buying this product.
