Product Description


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.

3-stage filtration and Hollow Fiber Technology provide cleaner water
straight 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 Contaminants
The 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 Tap
It 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 Convenience
Thanks 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 Replacement
The 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 Water
Water 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 fuel
  • Over 100 million pounds of greenhouse gasses--equal to taking 1,100 cars off the road annually
  • 213 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.

he good: Compact unit takes up very little space under the sink. Attractive faucet. Install SHOULD be easy.

The bad: The 'T' junction fitting that connects the filter to the cold water line is a piece of garbage. Throw it away. Don't even try. When I finally did get it hooked up, after running out to HD for extra o-rings, I turned on the valve to allow H2O into the filter and water started spurting out of the valve. Water was not coming out around my connections, mind you. The water was coming out around the "dial" you turn to open the flow to the filter.

I'm not a plumbing novice. In the just the last three months I've installed a toilet, a faucet, a garbage disposal and a dishwasher. This should have been the easiest of those jobs, by far (it wasn't). This valve is a tragedy.

So, my recommendation is to go ahead and get this filter. However, if you receive the plastic fitting instead of the brass, just throw it out and buy a brass fitting instead. It's the same fitting you would use to hook up a fridge/ice-maker to your cold-water line. If I'd just done that from the beginning, this would have been a 40 minute job. Instead, it took several hours over two days, including all the re-work and the two separate trips to HD.

I wanted to give this kit a good review because it saved me from another crappy one made by GE. I found this kit pretty easy to install and only had to do it once to get it right, without leaks. The faucet in particular is well made, solid, and attractive, and fits very well in my cramped sink area. The handle on the faucet is right in front, so you don't have to worry about it hitting stuff on either side. Good design, and looks nice as well.

The Watts hose connectors are higher quality than another kit I bought, made by GE. I wasted a whole Sunday afternoon installing that GE kit over and over, only to find it kept leaking. The problem with the GE kit is that it relied completely on push-in hose connectors, the kind with the little plastic collet with rasps to hold the hose in. And those connectors were not made well.

I'm much happier with this kit, even though it cost $35 more. It does also use 2 of the push-in hose connectors, but they were better made than the GE kit, and easier to insert. The other 2 connectors are actual compression joints that screw in. They hold much better and, after tightening, have not leaked.

The instructions in the box might throw you off a little bit. In one area, it has 3 sets of instructions for how to install 3 different faucets. You need to figure out which faucet you have, and ignore the other instructions. Not a big problem, but not as easy or clean a process as it could be. There was also a half-page addendum floating around the box which I didn't see till I was already done, which had a correction for one of the lines in the instructions. After puzzling over it, I started to suspect this addendum did not in fact belong to the kit I bought but some other one. Shrug.

This review is being written for Watts 3-stage water filter 531130 on Amazon.com 1/21/2011.

This system consists of a filter housing unit that mounts under the sink and holds three filter cartridges. The filter and housing are fairly compact compared to the previous generation of water filters. For routine filter changes, no tools are required. Each filter is removed by turning the water off at the shutoff valve and pushing a button above each filter. The filters are proprietary and not readily available in local stores. My previous system used screw on filters that were difficult and messy to remove and required a proprietary wrench.

The water tastes OK from this system, but in my case the tap water already tastes fine. I'm using the filter for added safety.

The dedicated drinking water faucet looks nicer than average. It's heavy and has an upscale nickel finish.

Perform a pre-assessment of your sink before you buy this product. If the answer is "No" to any of the following questions, then you should consider the additional difficulty of the project:

1. Does a shutoff valve exist under your sink for the cold water line?
If no shutoff exists, you will need to turn off your main house water line.
2. Turn on the cold water, and turn off the shutoff valve under the sink. Does the water flow completely shut off? If not, you will need to turn off your main house water line.
3. Does the faucet connect to the shutoff valve using flexible hose (common in newer installations)? If not, it may connect with hard copper tubing which will need to be cut, with additional fittings possibly required.

this was the 3rd filtration system that I tried.

all of them were similar and in the same price range; this one was the cheapest.

the quality of everything that came in the box was pretty amazing, down to the brass fitting, while the other 2 I tried were PVC.

the knock on this system is the installation manual picture of how to assemble all the washers- it was pretty bad, but I was able to figure it out.

perfect water stream and great taste.

I've had it for a month or so and no leaks or any other issues.

very, very simple to install and I may be the world's worst plumber.
