Culligan ISH-100 Inline Showerhead Filtration Attachment with Filter, 10,000 Gallon, White

Short version:Easy to install, does not leak, and does exactly what it says it will do. Chlorine smell gone, skin not super dry and "coated" feeling after showers anymore. Would buy again.Long version:I was tired of high chlorine levels in our city water and the irritation it caused my skin. My wife couldn't smell or feel it so she didn't sympathize. Fortunately this is inexpensive enough she didn't complain that I bought it. When I opened the package I was pleasantly surprised to see teflon tape included - this saved me a trip to the basement to dig mine up. Installation was a snap - take off the shower head (this also gave a good opportunity to soak the shower head in some CLR to clean the nozzles out) and while it was soaking, put the filter on.I think I understand why some people say theirs leaks. The stem that fastens onto the shower spout is also the pivot point for the filter unit. If you don't tighten the screw onto the main shower spout tight enough, this pivot point is not tightened enough and leaks. It happened to me, and another 3/4 turn onto the spout and the leak was gone. This might be tough to visualize if you don't yet own this, but it should make sense if you make the purchase and have a similar issue.I would not hesitate to buy this again. It does the job well - so well that even my wife could tell a difference in how the water smells and feels.

My original one broke after ~10 years, 4 moves, and no small amount of neglect, so I reordered this. You should know before ordering that it comes with its first filter. It also comes with a tiny roll of teflon tape, so you don't have to buy that or go hunting for some in your cobwebby basement shop, either. The new one is exactly the same as my old one, because you can't improve on greatness. I used to use this system to filter out chlorinated city water and that was a very noticeable positive change. Now I'm using it to filter silt out of my well water because my whole house filters aren't fully eliminating it, and there's a noticeable improvement with that too. My water pressure doesn't change as long as the disposable filter is still good. I'll have to keep on top of filter changes so that this one will last longer than a decade.

This is an inexpensive and somewhat effective product. For the price I did not expect it to be the most durable, and it's not. The connection points, including the threads, are made out of plastic which means when you are screwing it onto a metal shower head the threads will eventually get stripped. When installing make sure to use the included teflon plumber's tape at the joints as it will ensure a good seal and has some give so less likely you strip the threads on the initial install.Our water does seem to be more manageable, skin is not quite as dry and hair seems less damaged. Again I would not think this is catching all the chlorine or otherwise filtering with 100% efficiency but for the cost it's pretty good. I did not do water tests like some other reviewers.The filter did come in what looked to be a repackaged state, the packing tape to seal the pacakge makes me think this was opened, returned, and resold. Still installed easily and had all the parts.Replacements are easy to get AQUACREST Replacement for Culligan WHR-140, WSH-C125, HSH-C135, ISH-100 Shower Water Filter Units (Pack of 2) in multi-packs

Installing was a breeze, does not leak at all. It comes with special material to prevent leaking. I could notice right away that the water felt softer and there was not much chlorine smell at all. I thought I might be imagining it so the real test was on my skin which has been very bad for quite some time with dryness, itchiness, eczema and so forth. Two days after taking bath in the water with this filter my skin is showing improvement and is definitely less itching. I will update after a month or so, but improving my kids' and my skin was the major reason for buying this, as well as of course the reduction of toxins. I believe this is something so worth buying.Update: Two weeks later, my skin has improved tremendously. It is no longer itching, my eczema is gone, which proves it was caused by the chlorine and other bad stuff in the water to begin with. This is definitely a good buy for people with sensitive skin. I haven't had to use any steroid cream since buying this shower filter.

I purchased this not too long ago, and so far it has been working just fine. I have to say, that the product does what it advertised. My apartment has very hard water, and after you get out of the shower, your skin is tough and dry and my hair felt like a brick! It was almost like taking a shower in hot pool water with all that chlorine!!! I needed to find a solution to this problem. After searching, I have heard about the rave reviews that the Aquasana product was getting. I was fooled... not only did my shower feel no different, but the thing is huge and takes up a lot of room (not to mention the black water that comes out for the first few minutes!). Not a good thing. So I tried a MUCH CHEAPER Culligan filter. Thank God I did, because this actually works decently (and it was easy to install). During the first shower I took, I was just wowed the whole time. Not only did my skin feel better and not dry afterward, but my hair was actually soft and I could brush it normally again. Although it's not at the level of being soft water, it's definitely miles ahead of the crappy water I had before! You definitely get what you paid for and more!In conclusion, please listen to my review and don't waste your money on that expensive Aquasana bulky thing, and buy a Culligan filter, you won't be disappointed! I've already recommended this filter to my friends that live in apartments and dorms!
