## Description

Product Description The Watts Premier Filter Pure UF-3 system was designed with you in mind. Capable of running at low water pressures, this system does not require a separate water holding tank, does not alter the pH of the water, and does not require electricity, allowing a continuous, on-demand supply of premium quality drinking water directly to your tap. Includes three pre-installed filters, a parts bag, and a brushed nickel top-mount, twist faucet.This system kit includes one 5-Micron Sediment Filter for reducing dirt, silt, and rust that affect the taste and appearance of your water; one LVOC Carbon Filter for reducing VOCs; one 0.1-Micron Hollow-Fiber Semi-Permeable Membrane for blocking sediment and suspended particles, as well as cysts from passing through. The space-saving design allows this system to fit comfortably under your sink and requires fewer tube connections. It is also equipped with backflow prevention valves in the filter lid between cartridges, as well as double O-rings to prevent leaks. Furthermore, the unique swivel valve-in, push button release system allows for easy filter changes with no need to shut off the water source.With a maximum operating pressure of 85 psi, the included WQA certified filters are crafted from high-quality materials for maximum filtration. Filter life may vary based upon local water conditions or use patterns, but we recommend replacing sediment and carbon filters every 6 months and the UF membrane every 12 months.Water.

Review: No leaks, no missing parts - 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 over a 1" rubber gasket that didn't seem to be needed for the faucet installation and was not mentioned in the instructions. The instructions mention a brass and a plastic T-junction. Mine was plastic and it installed easily once I ignored the complicated instructions for the brass version. The junction worked perfectly well. The green tube connects to it with a dead-simple quick connect method (the John Guest locking system): just stick the hose into the hole and push. Same easy method is used to connect the green and blue tubes to the filter assembly. Much simpler and easier than dealing with sleeves and nuts. For the connections that require nuts and sleeves, I wrapped a bit of white teflon tape around the threads to improve the seal. When I first turned on the water a few drops came out of the green hose at the filter unit. Turns out I hadn't pushed the hose far enough! I screwed the blue tube's connector nut at the faucet shank pretty tightly and got no leaks. I ran the water for a few minutes and didn't notice any of the carbon particles mentioned in the instructions. My old Seagull filter did put out quite a bit of grayish looking water for the first few gallons. Overall I'm very happy with the installation and the water is definitely better tasting.
Review: Great tasting water, easy install, cheap consumables, good flow, way better than Aquasana - I replaced an Aquasana single tap unit with the UF-3, and it's just so much better (at least, so far). The Aquasana filters would slowly reduce the flow rate just a few weeks after replacing them, to the point where the flow was a weak trickle, so I was motivated to find something from a different manufacturer. Glad that I found Watts Premiere. It has a much better flow rate than the Aquasana, despite the Aquasana claiming to filter 2x or 3x faster. Flavor is great (although so was Aquasana's) and having a dedicated tap for the filtered water just works so much better than the Aquasana single tap approach. The specs on the UF-3 are better, too, from what I can tell. But I've only had this installed for week, so things may change once it's been working for a while. The install is pretty straightforward, with one exception - you need a knockout punch for a stainless sink, like mine. They're kind of a pain to use, but you only have to do it once. Factor in to your DIY price. Everything proved to be leak free after installation. Even with the need to make a hole in my sink, it was actually easier to install than the Aquasana. Aquasana's design requires using hand tools for some of the fasteners, because of awkward placement that seems to serve no functional purpose, and it requires 10 fasteners to be installed. The UF-3 just needed two, and is power-tool friendly. The faucet is decent quality, but ugly as sin. I'd really like to replace it with something that better matches my sink, but I have no idea what to get. I'll just deal with it. You get a filter set that requires replacement for two cylinders at 6 months, the third at one year. I was able to order a full year's worth of replacements for about $85 (less than half of what Aquasana replacements cost) with some careful shopping. With this ROI, I didn't feel that badly about chucking the old unit in the garbage, where it belongs.

### ⭐⭐⭐⭐⭐ great tasting water and high quality faucet
*by K***N on March 14, 2012*

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 water-tight seal, but they did. After hooking this filter system up (which took about an hour), I let the water run and was relieved to find no leaks. As other reviewers have noted, make sure you push the plastic tube all the way into their connectors. Give them a slight tug to verify they are in. Also, you may need an extra hand to keep the faucet steady as you tighten the nut from underneath the sink. I was impressed by the quality of the included stainless steel faucet and was surprised at how attractive and well-built it was. Since the water filter was the focus of this package, I expected the faucet to be more of an after-thought. But the faucet's high quality exceeded my expectations. Of course, pain-free installation and quality faucet aside, I bought this unit for its water filtering capability. And I'm happy to report it filtered the water just fine. The water tasted great. I immediately noticed the lack of chlorine taste and smell. I couldn't tell the difference between this water and the water from my old reverse osmosis filter. In conclusion, I'm very satisfied with this purchase.
