I had to do more research than I felt was necessary to actually figure out what I was buying and if it would work with the filter holder/filter set I bought at Wally World. So, being the nice guy that I am, I'll post it so you can make a better informed buying decision.. The 3M Filtrete 3US-PF01 is the advanced replacement filter cartridge designed to fit Filtrete Systems 3US-AS01, 3US-PS01 and Whirlpool Systems WHCF-SUF, WHCF-SUFC. This is a genuine 3M Filtrete Professional Water Filter. 54417. Replaces the old part number WHCF-SRC and WHCF-SR. The 3US-PF01 Product Specifications: Micron Rating: 0.5 Capacity: 2,000 or 6 months Flow Rate: 2.0 GPM Operating Temp: 40-100 F Operating Pressure: 25-125 psi Dimensions: 13 11/16" x 3 3/16" No Tool Required for filter change Filtrete Systems equipped with an internal shut-off valve Notice the "Micron Rating." This filter does a better job than MANY reverse osmosis systems!!! .5 micron rating is ridiculously small and will astound you with how much better your coffee, icecubes, cooking water, etc. will taste. You WILL notice a drop off in your water pressure at the sink tap when you use it. I consider that to be an engineering limitation and easy to live with. When you use the hot water you'll still have all the pressure you need. BTW, take your time when installing it. I know, if you've got a cramped under sink area it can get pretty claustrophobic under there. Well, suck it up, buttercup, and do it right the first time. Otherwise, you'll be under there SEVERAL times trying to get it right. Having an attentive helper to hand you tools, etc. will definitely be a big help for you so you won't have to slither in and out of there to get it done. Your effort will be worth it. You'll love the way your water looks and tastes. Btw, if you have REALLY bad water, I'd recommend some type of string filter before it. One of the "whole house filters" would be a good choice. (If you're concerned about your water quality, you should probably have one of those installed on your house anyways.) That way, you won't be clogging up this filter prematurely with large particles.

I got this filtration unit three years ago along with expensive 4-filter Royal Berky system. I did an extensive research for water filtration systems and didn't want a reverse osmosis filtration that removes naturally occurring minerals (although a few incorporate Re-Mineralization) that contribute to a good taste and health, and wastes a large portion of water to produce a fraction of drinkable water. My original plan was to double filter through Royal Berkey by using 3M Filtrete water for the purest water possible while retaining minerals. After a few months, I stopped using Royal Berkey because it required constant maintenance and Filtrete is so much more convenient and drastically improved water taste on its own with no noticeable odor from my tap. I use the filtered water for cooking, coffee/tea, drinking, pet water, aquarium, etc. The following performance data sheet info is included with the 3US-PF01 Advanced Water filter: Chlorine Taste and Odor - Avg % Reduction 97.5% Nominal Particulate Class I, ≥0.5 to < 1.0µm - Avg % Reduction 99.9% Microbial Cysts - Avg % Reduction 99.99% 3M also seems to care about their product from my recent interaction with the company. I recently replaced the 3US-PS01 filter as usual but tasted chlorine for the first time in 3 years. After a week of noticing the off-putting taste especially when used for my tea/coffee, I decided to contact 3M to report the problem. Although they never heard of such issue, they decided to send me a replacement filter and asked to send back the defective filter for evaluation. The replacement filter they sent worked immediately to remove the chlorine taste and I was able to send back the defective filter through a prepaid label. I finally decided to write this review after the experience, and I'm glad the company cares enough to investigate and improve their product consistency. One thing that you may want to consider is to install a dedicated filtered water faucet after trying it. For two years, I simply installed the system as the direction indicated on my existing kitchen faucet. The installation was very easy, but my cold water pressure got affected slightly and I felt like I was wasting filtered water whenever I was doing dishes or using warm water in my sink. Also, I always had to be careful to let the faucet water run for a bit to remove the stagnant unfiltered water in the faucet path, and just a bit of the unfiltered water was enough to ruin the taste of the drinking water. After installing a dedicated filtered water faucet that I got from Amazon (I used KES Z501C), my family can access filtered water immediately and my kitchen faucet water pressure got restored. It required extra work, but the effort was totally worth it. I suppose I'm saving my dusty Royal Berkey for the zombie days to filter local stream/rain water should the need ever arise, but I'm very happy with the inexpensive Filtrete system and never thought to research for another filtration system since use. I highly recommend you give this a try. Read more
