Rated 3.6 out of 5 by 59 reviewers.
Rated 1.0 out of 5.0 by I'll never buy another of this model Easy to install, visually pleasant. Great design to install, swap filters, overall use... BUT, some kind of internal design flaw. When not using filtered water, the filter housing was creating a water flow restriction causing poor water pressure. This was with filter bypassed. Changed filter, no difference. Removed product, great water pressure. Bought another, good for less than 2 months and did the same thing again. I'm done with faucet mounted filters. They're not worth the trouble. And this one, complete waste of money! October 28, 2014
Rated 1.0 out of 5.0 by very poor quality Bought it after trying a Brita product, which was not working very well. I am very disappointed. The product worked perfectly the first month, I was very happy -- very easy to use and to install. Just entered the second month an it is leaking like crazy. Tried various fixes, but nothing worked. Just went to the trash July 12, 2014
Rated 5.0 out of 5.0 by Great product The Pur water filter is easy to install and works perfect. There's an indicator light that will flash a few times when using the filtered water so you know it's working. August 21, 2013
Rated 5.0 out of 5.0 by Easy to install and looks great. This filter was very easy to install. It comes with four adapters that will fit 99% of all faucets. You will probably need a pair of pliers to get the old strainer off. The new adapters are finger tightened. Filter just clips on. There is a green light when filter is working and goes to yellow and finally red when it needs changing. The only thing is the filter side water stream is very slow but fills up an empty water bottle in about 10 seconds. DO NOT run hot water through the filter side. If I have problems I will let all know about it. July 2, 2014
Rated 1.0 out of 5.0 by cheap plastic connector doesn't stay connected. It does a good job of purifying your water, but does not stay connected. It has a cheap plastic aerator that screws into your faucet and the threads wear out and it falls off after a couple of months. I've bought two of these filters in the past 6 months and they both had the same problem. It would be a much better product if they used a metal connector instead of cheap plastic. I would not recommend getting one until they fix this defect. August 23, 2011
Rated 4.0 out of 5.0 by Good, but still has a design flaw that requires it to be replaced every three years or so. I've been using faucet-mount PUR water filtration systems for more than 10 years. The cost of the unit and filters is less expensive than buying water and obviously much more convenient. Unfortunately, in that time, PUR still hasn't mastered the attachment mechanism. A few years ago, attachment required screwing on the appropriate fitting (several were provided) and then screwing the unit with fitting onto the faucet. In order to tighten it adequately, you had to use channel locks that then marred it and over time when you bumped it, it moved, and you had to tighten it again, it would more than likely end up stripped. Now there's a new attachment design that still requires choosing the appropriate fitting for your faucet, attaching it to the faucet, then squeezing the buttons that open the mouth of the unit's mouth, and then just locking it into place. Unfortunately, if you ever accidentally knock the unit off the faucet, you can't reattach it. So, factor periodically replacing it into your decision. July 17, 2012
Rated 5.0 out of 5.0 by convenient and excellent the filter has worked excellently in both Michigan and Texas. I love it April 8, 2015
Rated 5.0 out of 5.0 by Best faucet mount purification system I've tried other faucet mount purification systems including Brita but as far as operability and overall quality, Pur beats the competition. The faucet hook up is a breeze, the filter replacement is really easy and the water switch moves with the push of a finger. Brita offers the complete opposite of what I just described. June 24, 2014
