I just installed one of these filters. The push-in connectors worked great. The only thing I needed was an adapter to connect the compression fitting to the flanged cut-off valve. The water flow is better than I expected. I now have filtered cold water from the kitchen faucet. Replacing the filter is simple and inexpensive. I wish I had changed to this new Filtrete filter sooner. I hated the job of replacing filters in my other water filter. In the past, I always delayed filter replacement because of the effort required. On this new unit, 1/4 turn removes the filter, and the water flow is cut off. Grab the replacement filter, 1/4 turn and water is ready for use.
Highly recommended!

I just installed this unit and it works great. Glad to be rid of my PUR faucet-mount filter. The flow rate is much improved with this unit. Installation was easy, except for an extra trip to the hardware store for a 1/2" adapter. The installation video on the 3M website was very useful.

I purchased this product after seeing the positive reviews it received. Unfortunately my purchase would not be one of them.

The filter is not difficult to setup at all (they even have a step-by-step instructional video on their web site if you need), it only took about 30 mins at the most. The issue came when turning the water on and losing water pressure after installation. The water line was cut so there was no excessive tubing to restrict water flow, so that wasn't the issue. 3M Filtrete touted their product as one that would not lose water pressure, but yet this was the exact issue I had.

I went to their web site for support... no support to be found on their web site. So I sent an email explaining my situation... to this day (more than 4 weeks later) I have yet to receive a reply regarding my issue. I considered returning the item to Amazon, but allowed myself to become content with the pressure until I decide to buy a replacement.

So if you are able to install the filter with no issues, then sure it's worth the purchase for the positive effects it can have on your water. But be advised, it may not work as advertised, so be prepared to send it back if you are not satisfied.

It's a simple install if the product came with the right parts. Typical filter lines are 1/4" compression on both sides. The adapter that comes with the product goes from a 3/8" tube to a 3/8" male. So now you have to figure out how to get from a 3/8" male pipe to a 1/4" compression. It took me a couple of trips to OSH and HD to get the right tube union which goes from 3/8" tube to 1/4" compression to get this right. So I skipped the adapter that came with the product altogether. btw the tube union that I needed is cheaper at OSH 3.99 vs 5.50 at HD. The other user error here was that I pushed the provide pipe into the filter and turned on the water and it was leaking all over the place. I then realized that I need to make sure that it is pushed all the way in. Once I did that, there were no leaks.

I have a lot of experience plumbing and since I have this experience I sadly have to use this knowledge.
I hate getting under a sink, but I installed this unit in conjunction with an on demand hot water unit.
Just give yourself plenty of time and draw out your design on the wall if you have to.

Yes, there are plastic parts, but they worked well for me and they are not exposed to ultra violet rays, so
they wont break down due to that and they are only used on cold water lines, so they will not crack or break
due to hot water exposure.

It was a no brainer to choose this system. I use Filtrete filters in my heating system and since I was going to
the expense of installing a hot water on demand system in my kitchen it was going to be filtered after all of that
work.

It works flawlessly and I've had it installed since before Christmas 2010. I wont have to change the filters as often
since I only use the on demand hot water a few times a week.

The water tastes great and you can always upgrade or downgrade filters to fit your needs.

It's a shame they'll make most people run down to the hardware store to pick up a cheap 3/8 adapter, instead of including it in the package. I use this in conjunction with a brita pitcher and the water tastes much better now. Using the brita alone always left my water with a bitter taste. Easy to install and worked as advertised, and cheap!

I installed this product a couple of days ago after finally figuring out the cryptic instructions. My faucet has copper stubs with hot and cold 1/2" male connectors. It was originally installed with braided metal tubing terminating in 3/8" female connectors which attached to the stopcocks. With the supplied instructions and 1/2" adapter I could not attach the supplied tubing to the end of the 3/8" original metal braided tubing. I finally figured out that if I climbed under the sink I could remove the original braided tubing and connect the supplied 1/2" female plastic connector to the original male connector on the faucet.

To improve the situation 3M should provide both a 1/2" and 3/8" connector or at least an adapter.

Otherwise I'm delighted with the filter. It's easy to install and use and there were no leaks even on the first try.

Unlike what the other reviews said, my water pressure did go down when connected to the filter. As far as everything else, I assume it is working.

My husband installed this with no problems whatsoever. It replaces a stand-alone filter unit that was sitting next to the sink, so it's a big improvement to clear the clutter with an under-sink unit. And you can't beat the price. Plus, replacement filters are available at Wal-Mart, which makes it all the easier to maintain.

I live in the suburbs of Washington, DC and we have very good water but you can still taste the chlorine. I bought this filter to remove the chlorine taste and smell from my drinking water, coffee and tea. This filter does the trick. There is no chlorine taste or smell when using the filter. Coffee and tea even look clearer. The filter was relatively easy to install. It uses the new push together connectors. I was skeptical of push together connectors at first, but they seem to work well and not leak.
