## 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. It's in our name and close to our hearts. Since 1874, Watts Water Technologies has been delivering innovative technologies that make the world's most precious resource safe and accessible. Everything we design is made to keep the Earth's most precious resource safer, cleaner, and more useful for our customers. desertcart.com The Watts Premier Filter-Pure UF-3 Water Filtration Device utilizes three-stage filtration to ensure you get cleaner, healthier drinking water straight from the tap. In addition to reducing lead, chemicals, and chlorine taste and odor, the UF-3 uses Hollow-Fiber technology to trap and remove even the tiniest particles from your water. Featuring a patented space-saving design that is perfect for houses and apartments, the UF-3 can be installed in a matter of minutes.Other ProductsYou May Want to Consider:All-in-One Water Test KitStandard Faucet with Air Gap, Brushed Stainless SteelWater Filtration Booster Pump Kit3-stage filtration and Hollow Fiber Technology provide cleaner waterstraight from the tap.During the lifecycle of a single filter, you can save up to 16,000 plastic bottles from being deposited in landfills. Three-Stage Filtration Removes ContaminantsThe Watts UF-3 filters drinking water in three stages. Once the system is connected, water from the tap passes through a five-micron sediment filter, followed by a heavy-duty one-micron carbon block filter that reduces lead and chemicals.The third stage of filtration involves a state-of-the-art UF Hollow Fiber Technology membrane. Hollow Fiber Technology uses standard home water pressure to push water through a semi-permeable membrane. Suspended particles and materials of high molecular weight are unable to pass through the 0.2 micron UF membrane, leaving you with only fresh clean water and dissolved minerals.This specially formulated filtration process is capable of reducing cryptosporidia, giardia, entamoeba, and toxoplasma, as well as a long list of chemicals--from herbicides and pesticides to disinfection byproducts and gas additives.Cleaner Water Straight from the TapIt is estimated that VOCs (volatile organic chemicals) are present in one-fifth of the nation's water supplies. These contaminants can enter ground water from a variety of sources, including herbicide and pesticide runoff, gasoline or oil spills, leaking underground fuel tanks, disinfection byproducts, septic system cleaners, and chemicals used in the dry cleaning industry.The UF-3 keeps you safe from these and other VOCs with its three-stage filtration, so you can turn on the tap with the assurance that you're getting cleaner, healthier drinking water.Simple Operation for In-Home ConvenienceThanks to technological advances, the UF-3's sophisticated filtration process, which was commonly used only in municipal water treatment plants and hospitals, is now available for home use. The UF-3 is capable of running at low water pressures, and it won't alter the pH of your water. For added convenience, the filtration system doesn't require electricity or a separate holding tank.Easy Assembly and Filter ReplacementThe UF-3 features unique swivel-valve, push-button assembly that allows for easy initial installation, as well as simple and sanitary one-step filter changes that don't require you to shut off your water source.The Importance of Drinking Clean WaterWater is critical to proper food digestion, kidney health, brain function, blood health, joint functionality, and more. It's important to make sure that the water you drink is devoid of contaminants. Thankfully, using a Watts water filtration device will ensure consistent quality for all of your drinking and cooking needs. In fact, when you use Watts' high-quality certified water treatment devices and filters, your water will be free of chlorine taste and odors, particles, and many other contaminants that can be detrimental to your health.*Please refer to the Performance Data Sheet for the complete list of claims for which this system is certified.Not only is the UF-3 filter a healthy choice for you, but it's also a healthy choice for the environment. This filter helps you minimize the harmful environmental consequences of buying bottled water. Incredibly, if a mere ten percent of North America's bottled water intake were reduced by switching to home-filtered water in reusable containers, we could eliminate:133,000 trucks driving an average of 500 miles--saving nearly 12 million gallons of diesel fuelOver 100 million pounds of greenhouse gasses--equal to taking 1,100 cars off the road annually213 million pounds of PET--equal to 1.5 million barrels of crude oil or improving the PET recycling rate by 10%Depending upon which Watts water-filtration product you use, you can prevent up to 16,000 half-liter bottles from being deposited in landfills--all in the time it takes to use and replace a single filter.The Watts Premier Filter-Pure UF-3 Water Filtration Device is backed by a three-year limited warranty.

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 and high quality faucet - 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.

### ⭐⭐ Plastic valve can FAIL!!
*by B***S on July 28, 2025*

System was easy to install and worked well UNTIL the plastic water shut off they supply cracked and flooded 1/3 of my 1st floor. It's only 2-3 years old and not covered under the one year warranty. No-one local carries the valve and Premier wants $16.67 for the valve and almost $40 for shipping. You'd think for customer relations they would send me one for free since this could have resulted in thousands of dollars in damage if it hadn't been caught within 1-2 hours of the failure. Three members of my family have these systems but I will not reccomend it in the future.
