Stronger, Healthier Hair

One of the most important things you can do for hair is to wash it with filtered, chlorine-free water. Your hair will be noticeably softer and shinier, your scalp will be healthier and your color will stay true and last longer.

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.

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.

Rated 5 out of 5 by from Awesome product I am already enjoying the benefits of my new shower filter after the first few showers! My hair is noticeably softer after only two showers. I was worried that my husband would not be satisfied with the water pressure coming out of the wand but I was pleasantly surprised. The water pressure is absolutely amazing; the filter does not hold any pressure back. Installation was a breeze. I did sign up for the filter savings program and now I do not even have to keep track of when to replace the filter. Great product!

Rated 5 out of 5 by from Great product! Have been using one of these for 4 years now. Moved to Ga from MA and the water was worse than MA. Bought one for both showers.

Rated 5 out of 5 by from Great shower - easy installation I have used this shower wand and water filtration for almost 10 years, and I wouldn’t use anything else. The wand head has several water flow combinations, and installation is easy. They also send me a new filter every six months, som8 don’t have to think about replacing the filter. Great product!

Rated 5 out of 5 by from Chlorine free Every time I took a shower I could smell chlorine. I purchased and installed this shower filter with shower hose and no longer smell chlorine. This is an easy install with simple instructions. I am a woman 71 years old and did it myself!

Rated 5 out of 5 by from Shower filter and chrome wand We love the system of filtering our water. All ready I am feeling the difference in my hair, it is softer and shiner. One obstacle we are working on and are open to suggestions. I am not very tall and my husband has PERMEANT BENT LEGS DUE to Cerebral Palsy, creating a challenge to reach the new hight of the wand in its holder. One other feature, we wish could be corrected. The wand holder is difficult to remove the wand at this new hight. A snap in design could be the answer. The plastic construction has already broken. A metal holder would be a welcome advance. Our many thank you to the company for replacing it with no extra charge. With God's greatest blessings Sincerely Matt and Loretta

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

Will you ever offer the shower filters and Wand in Black? All our bathroom fixtures are black, and the white and chrome you offer just do not match and clash. So I am hoping both the filters and wands will eventually be offered in black.
