Filtrete Advanced Under Sink Quick Change Water Filtration Filter 3US-PF01, for use with 3US-PS01 System, 1 Count (Pack of 1), White

It was very easy to install.

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.

it did the trick

Finally great tasting water or tasteless water! I grew up drinking well water at my parent's house and always hated having to drink public water due to the chlorine taste. I recently purchased a house that does not have well water, but the water is not terrible. I really did not want the huge brita filter on the faucet. In fact I am replacing the faucet with a new single post faucet so the brita will not work on it. This was the perfect solution to have great tasteless water. I read the reviews here on Amazon and decided to go for it. Install was somewhat of a breeze and the results are great.As for the installation it really is simple, but you need to be sure you snap the tubing in correctly. Push the blue tubing into the connectors all the way and pull to make sure there snug in the connection. I found that afterwards the seal or grey piece should be pushed out just a bit when the connection is correct. If you do not have it correct it will leak immediately. Also when you are hooking up from the filter to the faucet make sure you have 2 wrenches to ensure that the connection is tight. After my little mishap with the snap in fittings (Really it was my fault anyway) the installation was a breeze. I let the water run for 7 minutes like the directions told me to do.After the 7 minutes were up I put my glass under the faucet and tried the water. Finally my public water is now like well water or at least I cannot taste the chlorine. I am very pleased so far with this unit, and in 6 months I will be buying the replacement filter. I will update if anything goes wrong with the product, but I feel that there should be no issues. Also the water pressure did not drop at all at the faucet which if you own a brita style you know how much you lose when you filter the water. I am so pleased with this product.I would like to note that the filter when filled with water is pretty heavy. Make sure you install this into studs or use a nice strong screw with either a molly or an anchor.I am very pleased with this product and would recommend to anyone who wants great tasting or tasteless water!

Great filter system, I have had it for 8 years! Changing the filters takes less than a minute. Good water pressures with filter in place. Water tastes great!
