Aquasana Shower Filter | Dermatologist-recommended for softer, healthier skin & hair | Proven to reduce 90% of chlorine for 6 months | High pressure | Use your own shower head | AQ-4100NSH

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.

What an amazing product. I was suffering from flaky skin and scalp for many years and tried a lot of different shampoo, conditioners and other products nothing worked. As soon we got this and every shower feels great and flaks are gone my skin feels much better. I bought this and got one for my kids with handheld shower head.

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

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.

Got one of these a few months ago for the master bath shower. Our water has chloramine and very high TDS. Noticeable improvement in our skin and hair. Very happy with it and was happy to get one for the kids, so they could benefit from the improved water quality and resulting improvement in skin and hair health.

Update: 5 Stars for sure. It has now been eight months and we are so happy with this filter! Our black showerhead has no mineral build up and is as black as the day it was installed. It delivers what it claims. First, a little background to why we purchased this filter. When the government lowered the allowable levels of arsenic in drinking water our private community well (150 hookups) association was required to build a treatment plant to remove the now unacceptable arsenic levels. The low interest State loan to pay for this also required we start adding chlorine. The chlorine amounts added are so high that when my laundry is done washing and I open the door it smells like I had added bleach! I have to step back from the sink when I fill the dishpan because my eyes burn and run from the chlorine. And, when the powder room toilet refills we must close the door because of the overwhelming chlorine smell. Our scalps were itching and bery red after showering. My hair was falling out so badly it began to scare me and I was ready to see a doctor. And, we both developed very dry skin. I was very skeptical about the reviews for this filter, claiming great results after the first use. How could that be? What could we lose...? So, we decided to give it a try. After a month we are now among the people who report great results from using the Aquasana Premium Filter. I also saw results after my first shower, my hair was unbelievable soft and tangle free. It was as though I’d used a conditioner but, my hair was full of body not weighed down and lifeless like from using a conditioner. I am thrilled and so happy that my hairbrush is no longer full of hair ! We bought the unit without the showerhead and my husband installed our personal choice (new). During our construction my husband placed the shower plumbing to our height preferences (see pictures) so we have no issues of the showerhead location being to high or to short. Comments about dark water (carbon): it lasts for approx. 4-5 seconds, the time it takes my water to get hot. Not an issue at all. I will upgrade this to a 5 Star rating if the filter does not clog and is still effective at six months.

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 US B. 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.

After moving to North Texas several years ago, I noticed right away my hair/scalp felt yucky. My scalp never felt clean and my hair was becoming more damaged as time went on. Back in Ohio we'd had a water softener, so I looked for something that could be attached to myshower head. This has been a game changer! My scalp feels sooo much better and I notice that I requires less shower gel to get a good lather going. My skin feels better, also. If you're dealing with scalp issues, the first place to start is to get the minerals/deposits out of the water you're using to wash your scalp! All the products you try won't make a bit of difference if the water, itself, is not filtered. While our City tries to filter it, it can only get so much out of the water, so in the end this cleans it before it reaches my scalp or body. Be warned, though. Since it has a filter inside, when you move the temperature knobs it can take a minute or so for the water to change temp. as it has to run through the filter inside. So be patient and you'll have a much better showering experience. Depending upon how many use this shower filter, keep an eye on how often you need to change it. It does come with a shower head, but I just buy the filter system as I use my own beloved shower head. For one person, showering every other day, you'd probably need to change this filter twice a year. You'll be able to tell when it needs to be changed as your scalp won't feel as clean, and your ability to get good bubbles going when you shower will diminish. This has been a game changer for my hair , and you know how us women like to have our hair look nice, as well as feel nice! I am soooo glad I came across this wonderful product! BTW, I have not been asked to give any sort of review, this review is from buying the product myself and having used it for several years. Funnily enough, the other day my nurse in recovery (I had a small surgery) accidentally felt my hair when taking off that silly surgery cap, and she instantly wanted to know why my hair is so soft, feels like baby soft, she said. I immediately told her about this shower filter and she turned around and told the nurse next to her bout it and she came over to feel my hair. While my husband thought it rather odd, I understood. They both planned on buying one immediately upon getting home, the water is that bad in certain places around the DFW area. Please do not ever stop making this as you have a customer for life in me, and now probably these two nurses...lol

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.

Fue el mejor evaluado en internet, aunque no he percibido una diferencia, espero que si cumpla su función

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!

Es muy bueno filtrando, pero es muy pesado y por el proceso que realiza baja mucho la presión del agua.

I like it very much
