WaterChef U9000 Premium Under-Sink Water Filtration System w/Intelligent Monitor & Designer Series Faucet (Brushed Nickel), NSF/ANSI Certified for 78 Contaminants, 1,000 Gal., Stainless, Made in USA

I don't typically leave feedback, but this product is too good to not comment on. The build quality is so far superior to the plastic multi-cartridge units I looked at. The WaterChef is totally in a different class. The tank is metal with a clamp mechanism similar to what I've had on pool equipment, The flow meter is an actual flow meter. The faucet is extremely well constructed (and available in brushed finish). And it is all protected by a LIFETIME guarantee. The minute I opened the box I knew I bought the right unit. The instructions are clearly written in real English! This unit has a single cartridge which lasts 1000 gallons. (Typically one year.) The water tastes great! I highly recommend this unit. It costs a bit more, but you definitely get what you pay for!

1. The water tastes great! Crisp, refreshing and a HUGE difference from our tap. We live in Brunswick, ME which actually has very good water as it is, but I brew Kombucha so I wanted some extra safeguards that the water would be clean and clear. I had bought this unit for friends as a wedding present and they loved it, so I thought I'd give it a try myself.2. Filter replacement is extremely easy, and can be done in less than five minutes. No, you won't have to mop up likes and water spillage.3. CUSTOMER SERVICE IS AWESOME! I had an issue with the green light not functioning on the faucet. I emailed customer service and before the end of the day, I got a call back from Chelsey, a real live human that isn't based in the Philippines. She was kind, helpful and with no questions asked, looked up my order then said she'd send me a replacement part. Literally three days later I get a package in the mail with all the replacement parts I needed, plus an extra battery just to be kind and thorough!This level of ease and kindness is rare these days unfortunately. With this little kernel of good business sense and kindness, I'm a customer for life!Thanks Chelsey at Waterchef!

I have had the water filter system for couple years and the faucet leaks really bad. Contact customer service and was told the faucet is not covered by warranty. They asked me to purchase the faucet for $139.95. If warranty does not cover the faucet, what else left for the warranty to cover?

We've been using the WaterChef for several months now and are quite pleased with it's functionality and the water quality. The filter cartridge tank is small yet robust taking less area than any of the prior water filter systems we've used previously. The water dispensing faucet with the package is of top-notched quality and adds to the high value look of the kitchen sink counter. The three LEDs are a nice 21st century touch to alert of impending fliter change needs; however, we have not seen any indication of filter change so we can't really comment on the effectiveness of these LEDs.I've had two other 5 stage RO water filters over the last 20 years and must say that the output quality and water taste is equal if not better.In a nutshell, the biggest plus is very small foot print under the sink, excellent construction, luxurious faucet design and exceptional water quality.

We have a small kitchen with little counter space; this replaced a 1.9 liter Pur counter water filter. We were happy enough with the Pur, but really missed the real estate, so we opted for an under counter filter instead. We did a lot of research and found most under counter filter systems were made with plastic parts and prone to failure, so we took a chance on this even though it only had a few reviews at the time because the literature indicated quality, metal parts. Installation was a breeze, took little effort and time. It had to be installed on one side of the cabinet, though I don't recall why, when I would have preferred putting it on the other. Followed the instructions and had wonderful tasting water right away, unlike the Pur where we had to cycle through a number of gallons of water before the charcoal taste subsided. At one point filter indicator stopped working until we realized it had been knocked when the garbage disposal was replaced; we simply re-seated the cable and it works fine again. The only complaint I have at this point is that lately when we turn the water on it sprays all over. Unscrewing the aerator, the screen is not held in place by any means such as a gasket or o-ring. To be fair, I have not contacted the vendor for a solution, though I will soon. We installed this unit early December 2014 and we are just ordering a replacement filter.Update: Received and installed the new filter and the problems with the water spraying all over were resolved. Guess the old filter was only letting a small amount of water through, which we didn't realize since the battery for the indicator had come loose. We are only two but we live in a very hard water area (hence the filter) and use it for anything ingestible like drinking, cooking, plants, (3) cats. Replaced the (included) battery but it failed again soon afterwards. We will probably just assume an every 6 month replacement, which is an acceptable trade-off.
