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 Best decision to buy this! I am loving my new filter in the shower for several reasons: my skin and hair immediately feels better, less dry, and less itchy from the chemicals in tap water. My hair has a brilliant shine now too! That alone has made this purchase worth it. But I have bought this for health reasons. It is A known fact that chemicals in water are harmful to our health and our skin is our largest organ!!! I feel protected now.

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.

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?

Asked by: Beachbum
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

Where are your products made? I have a showere head and wand just got and they seem cheap! I had same from 12 years ago and they seem much better quality, very sad!

Asked by: RitaKay
Thanks for your message. All of our systems are certified non-BPA, non-leaching by the NSF International, a third-party nonprofit entity that develops standards for clean water, food and consumer products. The filters and media are assembled here in the U.S. at our Haltom City location just outside of Fort Worth, Texas. Please let us know if you have any additional questions. Hope this helps!
