Rated 5 out of 5 by from Bye bye hard water! We recently bought the Aquasana shower filter plus one for a friend and so glad we did. No more hard water stains on the shower walls or door plus softer skin and hair. It's easy to install and works great. When we contacted Aquasana with a question, they were quick to respond and very helpful.

Rated 5 out of 5 by from Great product I bought this shower filter after going away & experiencing a different water out of nyc & was amazed at how terrible our water was & did some research and came across great reviews of Aquasana so I invested in one & it’s the best thing I could have done, my skin isn’t dry & Irritated any more, I don’t have to use so much soap, shampoo & lotion

Rated 5 out of 5 by from Great value for the quality I have used my shower head with extended hose for a month now. It was easy to install and does the job. The water smells clear of chemicals as well as I know that what I bathe in and drink are now cleaner which makes anyone feel better. The shower head is smaller than some other heads but if you want to save water, which is a responsibility in southern California then win win

Date published: 2017-12-18
Rated 5 out of 5 by from Great filter Works well, no loss of water pressure. My only complaint is nit-picky for the wand, it would be nice if it angled down in a straight position. You have to do a side angle thing to achieve it instead. Not a huge deal, I still like the wand.

Rated 5 out of 5 by from Great shower with great features!!! I have 2 of these shower headsets and both my husband and I love them!! They are versatile with multiple spray options from soft to hard. I love ❤️ that the chlorine is filtered out leaving my skin soft and not itchy. The handheld feature is great because my husband is handicapped and that makes it easy for him to shower easily without a lot of help. He also likes the variety of spray options. Also this shower head does not lower the water pressure from the original amount which was very important to my husband since he likes the heavy or firm pressure and was concerned that the pressure would not be the same with filter. It’s a GREAT SHOERHEAD!!!!....
Date published: 2017-11-21
Rated 5 out of 5 by from Great upgrade Bought this to replace the original plastic one, the plastic clip holding the shower head broke. Was going to order a replacement and saw they now offered chrome. The shower head also comes off at end of hose for ease of cleaning, something the plastic version lacked.

Rated 5 out of 5 by from Awesome buy! So glad I purchased this water filter shower head. My expensive blonde hair color was not staying bright, and I knew I needed to treat the water I was showering and shampooing with. Easy to install and have enjoyed the benefits.

Rated 5 out of 5 by from Love this shower filter! We have used Aquasana Shower Filters for years now. I'm so glad that they filter out the chlorine which can damage our health. We also use the filter for our kitchen sink so we don't have to drink chlorine, fluoride and lots of other nasties!

Rated 5 out of 5 by from Something new in the shower!!!!!! We have been dealing with Aquasana for the past three years, since we moved to New Mexico, from Pa. Our home had a standard Aquasana shower filter, which we changed it for the filter, with the wand. We have a guest bathroom, so I ordered a new one for that bathroom. The sales person asked me which one I wanted. Chrome, or white plastic, like we already had. For a couple dollars more I ordered the chrome unit. When my wife seen the new unit, she said that one is going in our shower, and the one from our shower goes into the guest bathroom. We both love it...

Rated 5 out of 5 by from Water filter I am very pleased with my water filter. It was economical and easy to install. The customer service is so excellent. My countertop water filter is more than a few years old, yet aqua sauna replaced for free the housing when it started leaking.

Rated 5 out of 5 by from Life saver! I moved to Delaware from NYC a year and a half ago and that’s when I realized how different the water is in each state. NYC has amazing water but DE has very hard mineralized water. My hair started to change, it became dry and started to break and my skin became so dry! I used lotions, oils and nothing helped my dry skin condition. Someone suggested I get a shower filter, which I never heard of. I immediately started to research shower filters and Aquasana was rated one of the best! I decided to purchase the shower filter and it was so simple to install! I immediately felt the difference on my skin, it was like taking a shower in spring water! My skin is no longer dry and what a difference it has made when washing my hair! Before the filter I would wash my hair and apply conditioner and my hair felt like straw after rinsing it out. Now my hair feels silky after rinsing out the conditioner! I’m so happy I made this purchase, it has definitely changed my life!

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 the hand held wand angle down ? I have a very small shower stall in my apartment and how the angle of it appears it will shoot water at the upper wall.

Asked by: Amy Marie
The angle is adjustable to a certain extent. The connector between the filter and shower head can be adjusted to angle up or down, but I think the furthest down is about a 45 degree angle from the vertical or horizontal axis. my shower is only about 4 ft and it’s fine.

Does it remove arsenic and flouride?

Asked by: Melvin
Fluoride or arsenic both require Reverse Osmosis to be removed/reduced from water. We do offer a Point of Use Reverse Osmosis for your drinking water, and many of our Whole Home customers purchase it in combination.   You may read more about our Reverse Osmosis system at: https://www.aquasana.com/drinking-water-filter-systems/reverse-osmosis-claryum If you are interested in a system, please call 866.662.6885 or e-mail sales@aquasana.com and a representative will be happy to discuss your needs and options.   Thank you,   Aquasana Support
