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. Couldn’t be happier, and once you get used to having a handheld you will never go back! Simple install, and great for rinsing the shower too!

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

User Q & A

Does this help with sulfur and calcium in the water? We live in the country and have hard water. Will this help?

Asked by: Britty1717
As for sulfur I do not know, however as for calcium yes. An example we use to wash our shower curtain weekly, how only every couple of months and the yellow has come out of our white hair.

Does this help reduce calcium and lime buildup?

Asked by: Micheline
No idea. In fact, if you have calcium in your water I think it will eventually clog the holes in the shower head.

Does this system remove flouride?

Asked by: Yeng
The only way to remove fluoride from your drinking water is through Reverse Osmosis. Our OptimH20 removes 95% of fluoride plus 87 additional contaminants including lead, mercury, asbestos, pharmaceuticals, pesticides, herbicides, and more.

What exactly comes in the package? One showerhead one filter casing and one filter? I cannot find the detail anywhere

Asked by: Cecilia
Hi Cecilia - Thank you for reaching out. This specific product comes with the shower filter cover, the actual filter, and the chrome 5ft shower wand. We do have multiple configurations, but any of our shower filters will include the casing and the actual filter. Please let us know if you have any additional questions.

We have well water, so we aren't concerned with chlorine. We have hard water, and currently use an all-house water softener system, and a reverse-osmosis system for drinking. Winter time has our skin dry and itchy after showers. Would this filter help?

Asked by: Trying to get healthy
Yes I believe when the filters are fresh my skin and scalp feels moist not dry after a shower, I feel hydrated, this is an indication when to change a filter
