Excellent product, MADE IN THE USA -- it matters, and most importantly works well!We can absolutely feel the difference once a new filter is installed -- the water is softer and not nearly as abrasive. Skin and hair do better, this really does change the way you shower, and it's also very affordable and worth every penny! Also, as long as it's installed properly (which is not difficult), you will not have any "messes" to deal with -- and we have had this for years with no issues. The only downside is that it really does not be replaced more often than the recommended 5 months. I would say every 3-4 months. Still absolutely worth it.PROS:+Works well, removes most of the harsh chlorine in your water.+Skin and hair feel much better.+Affordable.+MADE IN THE USACONS:-none really, just make sure to replace it every 3-4 months depending on usage

This works great, just as described. It is not a water softener. It's a chlorine filter. Like it says. All these reviews about the high TDS readings are beyond ignorant. A water softener system is huge and costs thousands of dollars. This filter helps reduce chemicals from processed city water. Like it says.

Highly recommend. Works well.

So far, this is the only shower filter that prevents the water here in Jupiter Fl from turning my hair green. Also, my $60 shower & sink water filters even tested as CLEANER & SAFER then a separate unit/side of the house that uses it's own $2000 filter system. We can't live without this filter.

If your water is very hard and irritates your skin you need to give these filters a try, they might make a difference.

This thing is bulky and ugly but it works SO well. I bought it after moving to a house with well water and noticing discolouration, dryness, and breakage in my hair which I’d never had before. My skin was also becoming dry and itchy.I noticed the difference with this filter immediately. The water smell disappeared, my hair felt silky smooth, and so did my skin. When I needed a replacement filter after a few months, I opted to I try the Jolie filter which has celebrity endorsements and Instagram ads everywhere, because it’s much sleeker and had great reviews too. The Jolie filter is actually useless in comparison to this one, so I’m going back to Aquasana. Great product!

Not much to say other than this is a great filter and solid long term company. Have been using these filters for 6 years now after 10 years with another brand that routinely had issues if not installed very precisely. Aquasana is an excellent choice in my opinion. I've never had problems with them. Easy to install and reliable! Only $.006 per gallon of filtered water if you do the math. That's somewhere around 12 to 15 cents per shower unless your one of those types who sits in the shower for more than 15 minutes with water running.

This is a replacement cartridge for the Aquasana filter I already have in my "insert" shower-tub unit. I really like the filter itself, which lasted longer than expected and did not release nearly as much carbon residue as I expected with the initial flush (municipal hard water with lots of chlorine). I have a hand shower diverter with a quality metal push-pull shut-off valve installed between the filter and the shower head that came with the system. The tight fit of this combination means that the push-pull valve rests at an angle and is more awkward to operate than it was with a straight flow-through filter system. The amount of residual water in the filter means a cold shock if you are in the line of flow when it is first turned on, but I do a cold shock at the end of a hot shower, so do not mind (I do warn guests about this feature). The unit arrived two days earlier than the anticipated date (the order also included an unrrelated item).

Me ha funcionado bien, cumple expectativa en calidad y precio

not for me but I believe its works

I've used this filter for about 5 years now - and I can't be without it. I don't want to ever be without it, is probably more accurate, but seriously, the difference it makes in my skin, my hair, the rashes I get on my back, dry hands and nails, even difficulty breathing in the shower - this filter makes all those things seem like a bad dream. Just last week, during warmer weather when the humidity was high and it was raining off and on here in the Midwest, I was experiences the driest skin, and the driest hair and I just thought, so this is what happens when you get older - is it? I looked in my bathroom cabinets, I had 6 different shampoos each promising to fix the dry hair I thought was mine for the rest of my life, and next to the shampoos, I don't want to even tell you how many creams and lotions I'd collected, each one promising to do what the one before didn't. Nothing worked. All that money spent on nothing useful, I still itched, and my hair looked awful, no life in it at all.Then the lightbulb moment: I remembered that I hadn't replaced the Aquasana filter on the shower for over 5 months (and yes, I usually need to do it every 4 months, not 6, we take long showers in this house) - so I did, and the next day after one shower, I could feel the difference, less itchy skin, less redness on my face, and my hair, which had been coated with heavy shampoos that I'd bought to fix my dry hair - it felt and looked so much better right after the shower. Much healthier, and shinier.Fast forward to this week, one week of Aquasana filtered showers, and all is well. Even my legs don't feel dry, and my hair looks like it did before I FORGOT to REPLACE my Aquasana shower filter.Today is garbage pick up and I was able to throw away the half used bottles of shampoos that made me cough, lotions that either did nothing or made me feel sticky until I washed it off - now it's back to a simple shampoo and simple uncomplicated lotion. I'm telling you this filter makes all the difference in the world.If you find it to be expensive, I urge you to try it if you can, because at least for me, the cost of the filter for 4 months (my choice, long showers) is offset by my not having to buy expensive shampoos that promise to fix what's ailing the hair, but only make it worse, in combination with bad water - as well as body and face lotions that cost so awfully much, but again are only temporary fixes and can't fix the real problem of the coating that's on your skin from unfiltered shower water. It sounds like a commercial, but these filters may be expensive but they will pay for themselves by taking the place of the other products you'll no longer have to buy.I can't say enough good things about this filter - clearly by the length of this review, it would appear I've said plenty, so I'll shut up now, hoping you'll give this filter a try because I know you're going to love it. Okay. I'm done. I'm gone. Just buy it. You can come back here and thank me later. Enjoy.

Aquasana shower filter is very good product and I am using it for more than a year, hope you will have more AQ-4125 replacement cartridges in stoke soon.
