Culligan IC 4 EZ-Change Inline Icemaker and Refrigerator Filtration System, 4 Count (Pack of 1), White

I had one of those filters that you put on the end of your faucet for a number of years. It worked pretty well until I finally noticed that water had started leaking out from the base of the faucet neck. Apparently after all this time the back pressure caused by that filter and the weight of it levering down on the neck was causing the internal gaskets to fail. I removed the filter and the leaks stopped. But, this left me without filtered water. I wanted filtered water still but without the hassle of a pitcher in the fridge or having to replace my entire faucet due to the back pressure and levering caused by the on the neck one.Looking on Amazon I found a number of filters of varying prices and ultimately I decided to take a chance on this Culligan unit because the price was decent, the name is well known to me, and it had pretty good reviews. So far in the month or so that I've had it installed I'm quite satisfied with it. The water comes out at a very decent pressure, far better than my old on the faucet based filter.The kit comes with a plastic bracket that fits to the wall, some plastic tubing, a little adapter to put in-line with your cold water feed, some screws, the filter cartridge and the faucet.The faucet is not a super high quality item. It's mostly plastic, but it feels pretty solid for my needs. It actually comes in several pieces that you put together during the installation.I started my installation by drilling a hole in the sink. Make sure you have a sharp drill bit of the right size. The size they ask for is 5/8" which is one size larger than you'll find in most off the shelf drill bit sets. I thankfully had a 3/4" bit laying around from a different project, but my bit was fairly dull after that previous project so drilling was a bit of a challenge for me. I compared my 1/2" bits to the threaded stem on the base of the faucet and decided it just was not worth the risk of making too small a hole. The threads on the stem are all plastic and could be easily damaged by jamming the works into a hole that wasn't big enough. So do yourself a favor and get the right size drill bit before you start.After I had the hole drilled I unscrewed the wing nut from the base of the faucet and removed the metal plate. This left a plastic gasket on the base of the faucet that came off and I had to put back in place. After looking at the pictures I finally realized that the handle is supposed to go on the side of the faucet so I set the faucet in the hole and then reached under the sink to put the metal plate on and thread on the nut. Be careful not to over-tighten this as you could easily strip those plastic threads. Once it was snugly on the base felt pretty solid. I then took the neck of the faucet and attached it to the base and it looked pretty sharp, with no sign of the mangled hole I had drilled to put this in place.Next I shut off the cold water and proceeded to disconnect the feed line from the cold water connection on my faucet. I applied a little nylon plumbers tape to the connection and screwed on the plastic connector that came with the kit. A little more plumbers tape on the bottom and I reconnected the cold water feed line.After that I took the plastic bracket and using a sharpie clearly market the in and out sides so I wouldn't get confused later and hung it on the back wall with the included screws.Once all the major pieces were in place I took the plastic hose line, this is the same diameter as the kit that feeds my ice maker on my fridge, and carefully measured and cut two sections. On the base of the faucet you'll have a little plug that goes into the tube and a collar that goes over the hose. This threads onto the base of the faucet and once snugged down creates a good connection. The other end you simply wet and insert into a friction lock on the plastic bracket. The other line is even easier as it uses the same friction locks on both the hose line adapter and the plastic bracket.Finally I took out ye olde sharpie and wrote the date on the filter to remind me when I had installed it and connected it to the bracket by twisting it into place. Once it was snugly connected on went the water and after a quick check for leaks I turned on the faucet and a jet of water came streaming out. The instructions say you have to let it run for about ten minutes or so to let it flush out material from the filter. After the directed time I filled up a cup of water and tasted the sweet tasteless taste of success.The best part is that there is absolutely no impact to the water flow on my regular faucet and the new faucet provides water at pretty much full pressure. I'm sure this will go down over time but it is much better than my old filter.Looking at this solution I can see where if I ever so desired to step up to the two or three cartridge solution I could easily swap out the bracket by simply removing the plastic hoses from the friction locks. So if you are questioning whether you need the single cartridge or three cartridge solution know that you should be able to easily upgrade.

We have had this product for a couple of weeks now. The difference in the water is very noticeable. We were purchasing water by the gallon from a machine in our neighborhood. I'm using the Culligan water for my ice and it is smooth and comes out in one piece not breaking like it used to. The water does taste better (no taste). Very happy with this purchase. Also after looking at other filters the cost was definitely affordable.

Good kit for the price. Easy to install and works amazing from a well known brand. I can see and taste the difference in my drinking water. I ordered the "good" kit when it's time to replace the filter I will be ordering the "best" filter

I bought this product over a decade ago and now that I've moved homes, I bought another one. However, I can't believe that the water supply adapter is still not resolved with this product. If you have 3/8" sized water spigots, which most US homes do, then the 1/2" plastic adapter isn't going to cut it. (And given that it's plastic, couldn't Culligan have bothered to include 2 sizes?). So, like other reviewers here, it required either a trip to the hardware store (which also only had plastic tee valves in stock) or wait for an Amazon order (which had a brass tee stop in the right size for around $15) in order to complete installation. My other complaint is that the faucet fixture is still ugly and plastic-y. I think I would have gone with another brand of filtration system if not for the fact that I have a bunch of EZ filters still stocked up.

Been using these on my refrigerator for years. They filter great and remove the chlorine taste from the water and ice.

Easy to install. Been using this unit for years.

Can’t hardly get them anywhere else. We like our filtration system.

It should be noted that to attach to the supply line the tee included has half inch connections. It is normal to have 3/8" connections at the shutoffs under the sink so it appears the 1/2" tee is intended to attach to the fixture end and not the shutoff end which may be why so many reviews mention the 3/8" connection being a problem. Disconnect the supply hose from the faucet cold 1/2" connection and thread the tee on to the faucet and then connect the supply hose to the bottom of the tee. If your faucet has the hoses built into it that cannot be removed you will need to find another way to connect the supply. Check your faucet to see if you can thread 1/2" hoses onto the bottom to be sure.I read a few reviews that mentioned leaks occurring when the filter split. That seems like a pretty huge flaw if that is possible. To be safe I didn't mount it under the sink.It is an inexpensive setup and I can see how the fittings could cause a problem especially if the hoses aren't cut properly and squarely. Also the hose is marked to indicate that you have fully pressed it in and engaged the fittings on the filter. Once you push the hose in it seems like its tight but you want to push it in a little more, about to the lines on the hoses. If using another hose or a cut portion of the hose you need to make sure it is fully engaged. The connection to the bottom of the spigot was a little odd, it seemed you could put a lot or a little of the hose in and the water fills the full length of the threaded portion under the sink. You want to make sure that the insert that goes into the hose is inside the nut when securing, you can easily feed more hose into the fitting than is necessary and you won't have the hose insert under the nut to assist with the compression seal. I did not have any leaks from the press on fittings or hoses.I did not use the tee for the supply and instead opted to use longer 1/4" hose I had purchased for an Ice maker install and ran the tubing into the basement directly below the sink and conveniently above the sump pump hole should any major blowouts occur. This is not possible in all situations but this would also allow me to tee off the filter again for use as the ice maker filter with a bypass plug for the fridge filter. Without the sink supply to attach to you would have to find another cold water supply. I had an unused washer hose connection in the same location so it seemed a waste of time to solder in a tee and shutoff or using a saddle valve (I wouldn't use a saddle valve). I purchased a screw on hose connection to 1/4" compression fitting and inserted the supply into that, a quarter turn of the hose bib was all I needed to have adequate water pressure to the filter.The filter fills a gallon jug two to three times as fast as our old faucet mounted Culligan Filter that served us well for the past three years. The water seems to taste the same but we have only had it three days. The quality of the spigot is good enough for me, it seems solid enough but I don't have anything to compare it to. If we have a problem with it then I will replace it someday, no big deal. I am happy we have filtered water and could finally replace the sink faucet we neglected to change because we were dependent on the old Culligan filter. We filter for taste and Chlorine as we have city water, it should last us the full 12 months between filter changes I hope.
