Y. Wang: I had this water filter for years then developed leaks at joint of valve so I change the whole unit.

Iyiad: I did flush 3 gallon of water at first use. But I am seeing like chlorine in water. What is really strange, the tap water looks crystal clear comparing to filtered water!

B's from Alberta: We brought this filter down to our home in Costa Rica to give us an extra measure of water safety. The Water in most of Costa Rica is "Potable" but the taste and smell is not always the best and recent water rationing means that many complexes have commissioned tanks to tide over users when municipal water is turned off. We never want to be blindsided by accidental biological contamination which would occur quite easily.

The filter was very easy to install if you have some minor plumbing experience and it works well at low to modest pressures. Access to filters and fittings is super easy and we really like the way it works. Maintenance is very well thought out and super easy. Spare filters are readily available on line

Water comes out of the filter tap gently with lots of very small bubbles in it and it tastes quite soft. We place nice glass jugs in the fridge and within a few minutes the bubbles have gone leaving crystal clear water. As a result we now drink more water and have eliminated plastic water bottles from our regiment....NICE

Elliott: Definitely made a change in taste & smell of our water. Significantly lower solid-count in the water, and the Chlorine smell / taste is gone.
Coffee and Tea tastes very different (for the better). Even when cooking (IE: Pasta, Rice, steaming vegetables, etc.) there is a noticeable difference in the result.
Didn't have the space to dedicate to a Reverse Osmosis system, and didn't like the idea of wasting water. The UF-3 system "fits the bill".
The only reason not to receive 5 out of 5 rating from me is the quality of the plumbing fittings included with the kit. While they get the job done (1 connection needed some "fussing" to stop a slow leak), there are definitely higher quality options to be found / used (an inexpensive trip to the home improvement store was my solution for piece of mind).

Kenneth Chen: Before I selected this, I considered the Multi-Pure MP750SB and the AquaPure AP-DWS1000. Both were highly reviewed on Consumer Reports but were also considerably more expensive than this unit, each costing more than $300. I'm sure both got the job done but I couldn't find a reason to spend an extra $200 to $300 for a filter that didn't appear to be more effective than the Watts Premier. Also, the two more expensive filters had few reviews here and the ones that were written seemed suspiciously biased.

Anyway, I selected the Watts Premier mainly due to the high ratings here, its reasonable price, its use of widely available Watts filters and the certifications that validated its effectiveness. I was apprehensive about the installation after reading the problems some people had with it but mine went smoothly and without problems. I was concerned about the effectiveness of the plastic diverter valve but it worked fine. I took another reviewer's advice to use teflon tape to make a tighter fit between the brass fittings and the plastic valve.

I was also concerned about these snap-in, connectors you slide the plastic tubes into. I wasn't convinced they would create a...

Apta: At first I looked at reverse osmosis systems but was put off by the wasted water and having to tamper with the drain pipe under the sink. So I kept looking and found that the UF-3 has pretty good filtration specs, down to 0.2 microns thanks to the UF membrane. This system, certified to meet NSF/ANSI Standard 53, is able to take care of volatile organic compounds (VOC), heavy metals, and fluoride. See what the NSF certification entails here:[...]and here: [...]. Having used a Seagull IV water filter system for the past 20 years, this was a step up in filtration quality.

I was a bit hesitant to do the installation since several reviewers commented about missing parts, leaks, and about the plastic T-junction (the piece that connects the green tube to the water source). But since Costco also sells the UF3, I figured that it couldn't be that bad since the store seems to carry mainly high quality products.

I do admit that there is some confusion in the instructions. The faucet was made for three different systems and has three sets of instructions printed right on the box. Ignore all of them since the correct instructions are in the installation pamphlet. I did have left...
