Cleans water nicely
Its a good filter, easy to install, made of lightweight plastic (a good thing because it will not make the shower pipe droop down like the old heavy ones did) and it completely eliminates all the smell of chlorine and everyone stopped complaining of dry itchy skin after I installed it.The only tip I should pass along is that the you install a new one, do instal the hose and point the hose at the drain, as close as you can get to the drain) then slowly turn up the water. The first few seconds that the water is running it will throw out some carbon from this filter. The carbon is, of course, completely harmless but its particles are so small that will get trapped in the texture of your shower floor and leave a black mark. It eventually goes away but it might be noticeable to some people.The other tip I can offer is that this is an effective filter but it clogs up easily. There are only two of us that use the one in the master bath and it only lasts 4 months (once it lasted 5 months, I got al excited but the next one only lasted 5 months again). I do wish that it lasted longer because I have having to recycle the perfect shell, but that is a small wish for future versions.I highly recommend this unit if you have excessively chlorinated water in your shower.

Only buy one at a time
I’ve been using these filters for 15+ years, first when we lived with well water that had a great deal of iron and now on city water that is just very, very hard. Clearly, they work well or I wouldn’t keep buying them. With the well, I changed them out every 6 months. Now on this hard city water, I need to change them out every 4 months. I believe it’s because the water is so much harder than our well water was. When we moved to the city, w e took our filter and had an extra one, so they were the ones I usually bought, and they worked just like on the well water.. I mention this because if I hadn’t had this experience if their lasting 6 months, I’d wonder about the quality of the product since they say they last 6 months.I would give 5 stars because this filter really works. My hair is a rat’s nest on this hard city water, weighed down, looks greasy, gets smelly-dirty extremely fast, just gross. My skin is itchy…all that goes away with this filter. It’s really a good product.However… I used to buy them in pairs, but the last purchase, the second one leaked. Read the one-star reviews, and I had a similar experience with filter #2, which I could not return because it was 4-5 months after my purchase. First the thing leaked and trickled water, then very soon began spurting water, and we went through that filter in a matter of a few months. Since then I only buy one at a time.I didn’t contact cs for a replacement, so I don’ know how that would have gone, but the 2025 1-star reviews don’t look encouraging, so I continue to buy one at a time. Just in case. Beware!I never had this leaking happen 5, 10, 15 years ago…is this a new development in their quality, I’ve begun to wonder.

Constantly leaked
I purchased the Aquasauna Shower Filter from Amazon because I heard great things about this product. I received this product on 9/21/2025. Since day one when I installed there has been a small stream of water where the filter screws into the shower portion. Today I put plumbers tape on the threads in an attempt to fix the issue and it did nothing. I checked all the gaskets and it did not visually appear damaged. I made sure it wasnt cross threaded, and it wasn’t. Nothing appeared to be cracked or broken. I had taken it off and on about 10 times, to see if I was missing anything, then it snapped at the neck. The part where it meets up with the water outlet. This is very frustrating because I only had their product for a short while. It was working at it should as a filter, but now I have nothing. I have submitted a request to see if they will replace their product, since it is past the 30day return with amazon. If they do, I will update my review. If not then it goes down to a 1 star review and will make sure that no one I know attempts to purchase their product.Update: sent an email to Aquasauna about a replacement part, never heard back from them after two emails sent. Garbage it goes and what a waste of money for me. 1 star product for durability, it leaking and terrible customer service. I would not recommend

Difficult Installation
This item is probably OK, if you can use it. It did not work for me and I will try to return it. The Benefits:A. Made in USB. Does not lower the position of the shower head.C. Does basic filtering, maybe less than 6 mo.Downside:a. It only works with a narrow shower head. We have a large diameter (maybe 6”-7”) shower head, that cannot be screwed on this filter.b. This filter comes without any basic items required for installation: such as teflon tape and in-line filter gaskets. Which are necessary for installation.To add insult to injury, the Item was left on the ground, in the open walkway of our building, instead of delivering it to our front door as instructed.

Our water is very good but a bit alkaline leaving water scale on the shower and dry itchy skin. Though skeptical of these things I decided to try it. It works well. The shower is staying much cleaner and our skin and hair feel better. I bought the filter only because we really like our shower head. Everything fits up but you have to offset the the hose and body of the filter a bit because of interference. Most existing hose / shower head combos would have this minor problem. Remember that the water has to flow through the filter before coming out the head making the temperature changes longer. Overall I’m pleased.

Water feels noticeably lighter and my hair is so much softer and less irritated. Highly recommend!Only thing I’d caution is that it wasn’t the easiest to install. I’d recommend using plumber/Teflon tape around the threads of the screw-in parts and a wrench. Once installed, it works really well!

I like it very much
