Customer Reviews for Filtrete Maximum Under Sink Water Filtration System

After two months in use the hose to the water supply came off and flooded my kitchen cabinet within seconds. Luckily I was in the kitchen when it happened, otherwise our whole house would have been flooded. I will not reinstall it again, unreliable, can't believe that this product is still on the market.

This is my initial review after only a few days so far. I purchased this to replace my in-fridge filter "every drop 2" which on my specific model refrigerator only filters the water dispensor and not the ice. My fridge has a dual ice maker and there's a big difference in filtered ice vs non-filtered ice. Also, these tiny in fridge filters don't last long and only have basic filtration. My "every drop 2" was only rated for 200 gallons. This Filtrete is rated for 1500 gallons. Should last several years. Thankfully once I removed my in-fridge filter, the fridge bypassed the in-fridge filter automatically with no plug needed. I ended up purchasing additional parts because 1) better quality piping desired and 2) flush valve desired. Flushing a new filter via fridge dispensor would take forever. I now have a turn valve to flush out a new filter in my basement. I also DID NOT USE the plastic threaded coupling/adapter as that seemed like a bad idea. Any pressurized water and plastic threads is a recipeit for disaster. I bought type B 1/4 inch pex (3/8od) which is stronger and has better longevity. The included Parker polyethylene parfex has a 0.62 wall, and per Parker's website, this 0.62 pe piping should last "several years." That was not comforting for me. 1/4 (3/8od) pex is less than 2 dollars per 5 foot pipe. Plus I used a brass compression insert/stiffener inside the pex with a plasic ferrule which I have a lot more confidence in that using a plastic threaded adapter. I also bought a Watts 3/8od to 1/4od adapter to go to my 1/4 brass supply line. So far so good, and as you can see, this filter is way way bigger than the tiny in-fridge filter. Happy with this setup! By the way the pex I utilized was Apollo 1/4 pex (3/8 outside diameter). So far no leaks. I wish the filter inlet/outlet had mechanical connections rather than push fit, but so far so good. Taste is better than the "every drop 2."

I installed this filter under the kitchen sink. It took me about 30 minutes from unboxing to running water and removed all unwanted tastes. The next one will probably go in the bathroom.

The filter comes will all the parts you need PLUS a reminder timer. That's really helpful so I don't have check the date. we installed these on 5 gallon water coolers to filter the jobsite water. if it ever gets warm outside again, we'll be able to add ice to our filtered water.

I bought this system to replace the Kohler filter system after Kohler doubled the price of its water filters in 2018. I still have my Kohler water faucet above the sink, but this Filtrete system is now my water filtration under the sink and the replacement filters are less than 1/4 what Kohler charges. Water tastes great, makes great coffee and my dog loves it!

[This review was collected as part of a promotion.] Purchased 2 months ago to filter kitchen drinking/cooking water from municipal supply. I have a whole house filter on water intake but it is only a string or paper type for heavier sediment to protect water heater. This one is for drinking water/ice maker tapped in. Went in quickly without problem. Just followed directions on package. Press in fittings work fine, no stress. My only concern now is I cannot get it at local big box store and their website says not available. Water tastes great, no noticeable odor.

It literally took 10 minutes to fully install and get it running. I had horrible tap water that smelled and tasted awful. Even cooking with it made my food taste funny. This has completely solved all of these problems. The water flow is a little slower but a lot better compared to a pur or britta faucet filter. It's Well worth the money to invest in your drinking water. Just use some extra Teflon plumbing tap on all metal threads and make sure to push all connections into the quick connect pieces all the way in. Awesome product!

[This review was collected as part of a promotion.] Installed the 3M Filtrete Under Sink water filter. Goes in pretty easily, though I would have liked more images on the instructions. Water does come out slower but having filtered water, like we do at the refrigerator, is a plus. No more having to keep a Brita in the fridge. 3M provided me with the filter to review. However, that does not change my review because I'm the one who had to install it and has to live with it.

[This review was collected as part of a promotion.] A couple of weeks ago, I received a free sample of 3M Filtrete Maximum Under Sink Water Filtration System, compliments of the good folks at 3M. First, I would like to say it has made a distinct difference in the taste of our water for the better. It's super easy to install, just make sure to cut off your cold water first. It took three simple tools, a drill, a pencil and a wrench to install. Make sure to leave 2 to 3 inches underneath your Filtrete system to allow for filter changes every 6 months. If you have a garbage disposal, make sure your Filtrete system has enough space between it and the garbage disposal. It was so easy to install and I love that the filter lasts for 6 months, not to mention all of the money you save on bottled water! It's definitely a thumbs up from me! Thank you 3M!

[This review was collected as part of a promotion.] I received a free sample Of 3M - Filtrete™ Maximum Under Sink Water Filtration System and the installation sounded like it would be complicated but it actually was easy.Took about 30 mins from start to finish and produced a wonderful outcome. The water from our well now tastes good and I feel secure letting my family drink it. Good value and saves on bottled water now.

[This review was collected as part of a promotion.] I just received a filter sent to me by 3M to test and review. Although I have not had the chance to really see any major difference with the old reverse osmosis filtration system (which is already an indication of good performance), one thing Incan tell you is that the installation process is simple and straighforward. The instructions that came with the filter are clear and easy to follow and it only took me 15-20 minutes to get it all set. I will be executing some water test in the future and post them forveveryone to read. For now, it all seems good and 3M is alreadybdelivering on its promise

easy to install, affordable health benifits to home owners or renters

I'm a big fan of Filtrete Maximum Under Sink and have been using this product for at least 5 years. The fact that it is NSF certified means a big deal to me, all of our kitchen pots and pans, dishwasher, and more are all NSF certified. The flow rate is very good and slightly less than without the filter - it's a filter and it's suppose to remove stuff so it's also expect to reduce flow rate and if it didn't, I'd wonder if the filter was working. Other than reading an article from Michigan State university and on NSF, all filters with NSF must reduce PFAs and PFOs "o make a PFOA/PFOS reduction claim, a water filter must be able to reduce these chemicals to below the EPA healthy advisory limit of 70 parts per trillion. Certified products must be retested periodically and manufacturing facilities must be inspected every year, which ensures products continue to meet all requirements. To find products that are certified by NSF to reduce PFOA/PFOS in drinking water, see NSF’s certification listings."

My plumber installed it and I’m using it and sm very happy!

The tubing was too loose around the piece they give you to screw back into the water fitting outlet. Returning. Pain.

Simple, easy to replace filter, water tastes and smells great!

Easy to install fit easy in space under sink

Super easy to install with significant improvement to tap water quality and taste!

easy to install and have the filtered water I need

I purchased this filter as an alternative to a reverse osmosis system that went bad and would have cost $1,300 to replace, not to mention the yearly maintenance to replace the two filters on it. ($100). So, I already had a dedicated line and faucet for drinking water. The filtrete was easy to install. My only trouble was I didn’t have much room to work because we have a very deep sink. Because of this, it was hard to snap the water line in and it leaked a bit at first, but I finally got a good connection. The cloudy water is normal and is caused by air bubbles. I did some research and discovered that the cloudier the water, the better the filtration. And the water becomes clear in a few seconds. I’m happy with the purchase, and my wife is even happier!

Easy to install and retrofit to my dedicated spigot.

Water tastes great! Was easy to install and super easy to change the filter

They dont include the proper quick connect fittings. Had to get my own. Filter works fine otherwise

I have had this water filtration system installed for about 2 years now. I've changed the filter before the recommended 6 month interval however both times my water pressure has almost completely stopped. This product works great for about 1-2 months max. I looking into switching systems to something a little more reliable now.
