Rated 5 out of 5 by from Love this filter! Easy to install and makes my showers infinitely better! I have very chlorinated water and I can't smell the chlorine at all anymore!

Rated 5 out of 5 by from So far, so good and I am pleased When I move out of state next year, will take this item along. Moving from a city with hard water, the quality of which depends on which section of the city one lives...to an alpine forest where I will have a well installed. After I move will purchase whole house water filter. Thank you for a little more peace of mind.

Rated 5 out of 5 by from Easy to install and works great! Installed quickly and easily. The filter works very well at removing the odor in the city's water. Using the filter has made the water seem less harsh and my skin feels much better.

Rated 5 out of 5 by from Love it! I purchased this brand and unit after my other filtered hand held showerhead broke. It was the clunky type that had the filter in the handle, which made it not only heavy, but inefficient. I’m glad it broke, because this one is fantastic! It has great water pressure and the range of types of water spray is great. The only negative is that it leaked from here the unit screws into the inlet pipe that comes from the wall. My husband turned the filter unit at an angle to get it to stop. It gets the job done, and I love how much softer my skin is now and the water feels great that comes out!! I’m so glad I purchased this!!

Rated 5 out of 5 by from Honest review I ordered the Aquasana showerhead filter because I was moving out to the country where we have rusty well water. I absolutely love it!!! It works better than I ever imagined!!!

Rated 5 out of 5 by from Quality Product The instructions for installation made it a simple process. I immediately noticed that the water is softer and it did not affect the pressure at all. Excited to see if this leads to any skin benefits in the near future.

Rated 5 out of 5 by from Nice Showers! My fiance installed the shower kit and was the first to test it out. Priming the filter was simple and fast; he did it in the shower stall. Both of our skin issues have been alleviated (mine went away completely) which leads me to believe that our sensitive skin was reacting adversely to the pollutants in our city water. This is our first purchase of this kind and from this company, so we immediately signed up for the continuity program. What surprised me the most was the customer care: Brent reached out to save us more $ by informing us we'd bought during a promotional sale. We ended up receiving a countertop model of a water purifier unit. That has yet to be installed but once it it we will use it a while and publish the review. Thanks!

Rated 5 out of 5 by from Excellent product - Easy to install. This product fit my needs perfectly. It delivers clean water in my shower and was very easy to install. Fool proof actually. The water pressure out of the hand held device is perfect. The handle is very light and easy to use when removing to wash hair, etc.

Rated 5 out of 5 by from Huge Improvement using your well water filters When I initially called Aquasana I didn't think that they carried filters for well water. But, amazingly, they do! The well water filters are not advertised on their website. What a wonderful difference in my shower now. Soap really suds's great now, skin feels really clean and without any residue from the well water. Also, hair is shiny once again and much more manageable. Also, utilizing less product. This is a great purchase and worth every penny. I am a renter. But, if I were the owner I would invest in the whole house system. Well water has different things in it over city water. It does not have chlorine or fluoride but it has iron and other contaminants. Aquasana is the only shower filter that I could find that has well water filters to remove iron plus other contaminants known to well water.

Rated 5 out of 5 by from Awesome Product The filter was easy to install but the metal connector was hard to attach to the inflow pipe. It was rather slippery. Other than that, the water quality has improved and the water acquired a better smell. It also became softer on the skin. I highly recommend this.

Rated 5 out of 5 by from Hair I just wanted to say that my daughter has very long, think and wavy hair. Without the aquasana water filter in the shower she ends up with uncombable knots in the middle of her head. With the filter her hair comes out smooth and unknotted. This is a lifesaver for our family. Plus as the advertisements say, it really does allow you to use less shampoo and conditioner.

Rated 5 out of 5 by from As advertised After a very simple installation the shower filter was purged and put to use. We were delighted with the great water pressure, no slack off there at all. My wife's first impression was how much better the water felt and smelled. She liked the shower filter and the wand is nice to use and nice to look at.I had to concur and now we are contemplating a whole house system. Nice product....as advertised

Rated 5 out of 5 by from City Shower Water caused stinging sensations Needed a filter to address this startling problem ASAP. Read up on filters and found that the best solution was a dual filter that contained a charcoal component. Aquasana had a sale at the time so I decided to try their shower filter and glad I did. Product has reduced the water irritation by at least 75% so now I can take a shower with much less suffering. What is going on in the City Water is very concerning so be mindful of what quality of water you are bathing with wherever you live.

Rated 5 out of 5 by from LOVE THIS FILTER! Installation was super easy! Noticed a difference in how my hair felt after just a couple of days - I didn't realize how much the city water was drying out and stiffening my hair. After a few weeks we can tell a difference on our skin - not nearly as dry. I wish I had bought this sooner! I recommended this item to my sister, and she is having the same great results.
Date published: 2018-12-12
Rated 5 out of 5 by from THIS SHOWER FILTER IS AMAZING!!!!!!!!!!!!!!!!!!!!! I had to write this review after just two days of use because the difference to my hair is amazing. I have been dyeing my hair for years and it's dry, brittle, broken and not in good shape at all. Even after using conditioner I would still have to use a detangler comb and detangler product to get through my hair. After just TWO DAYS of using this shower head, my hair is shiny, soft and I have not had to use a detanger comb OR product. I picked up my brush and it went straight through my hair. I expected some difference in the water but I really did not expect such a dramatic difference to my hair. I am SO glad that I made this purchase. Oh and it was easy to install too so that was an added bonus. Plus it has a nice massage feature and has really good water pressure. There is not one negative thing I have to say about this shower filter.

Rated 5 out of 5 by from Goodbye dry dull skin! I have been using this for 2 years and I hate showering anywhere but at home now. Getting the chlorine out of my shower has made a huge difference in my skin, even in the winter. Hair needs less conditioner because it's not getting stripped and color lasts longer. Also, no more funky orange rings around the drain.

Aquasana FAQs

  1. Do I have to pay for a plumber to install the system?

    Aquasana shower systems are very easy to install, and you can do it yourself in minutes. No plumber is necessary. If you have any questions or need assistance, our technical support representatives at 866-662-6885 can walk you through the installation process.

  2. What is the flow rate of the AQ-4100, AQ-4100NSH, & AQ-4105?

    The optimum flow rate for the filter and shower head is 2.5 gallons per minute.

  3. Can I use my own shower head or hand-held wand with the AQ-4100?

    Yes, you can use your own shower head. The AQ-4100NSH is the correct model for individuals using their own shower head. Just remember the shower head needs to have the same 1/2 inch connection as standard shower heads and the ideal flow rate would be 2.5 gallons per minute. If your shower head processes more than a 2.5 gallon flow rate per minute, the quality of filtration may degrade slightly. Increasing the flow rate by changing the shower head reduces contact time with the media and will reduce the filtration quality. If you decrease the flow rate of the system by using a different shower head, or use a shower head with a shut-off switch, you may cause damage to the system and void your warranty.

  4. Can I use the shower system for drinking water?

    Drinking some of the water during your shower poses no health risk. However, Aquasana does not recommend that you use the shower system as a primary drinking water source since it is not designed as a drinking system and has only been tested under shower conditions and regulations.

  5. Can I hook the shower system up under a constant pressure application?

    No, the shower system is designed to allow the water to consistently pass through the system as it filters. If the system is under constant pressure and unable to release the pressure introduced into the system during filtration, damage can occur to the unit.

  6. How do I know if the Aquasana shower system will fit the shower pipe coming out of my wall?

    Most shower connections are 1/2 inch, which means that the Aquasana shower systems will fit the shower pipe in most homes.

  7. How much chlorine does the shower system remove?

    Aquasana shower systems are tested to remove 91% chlorine for 10,000 gallons.

  8. How do I know how many showers it takes to use 10,000 gallons?

    10,000 gallons at 2 1/2 gallons per minute = 4,000 minutes of showering
    - You can take 400 10-minute showers
    - You can take 267 15-minute showers

Does this help with calcium?

Hello, We appreciate your question. The Shower System will help reduce your skin's exposure to harsh chlorine and synthetic chemicals that can cause skin damage and excessive drying. Unfortuantely, the Shower System will not help to reduce nor remove calcium in the water. -Aquasana
