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.

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

Flow rate is very low on my old and new units. Volume and flow normal with unit removed. Is there a water saving feature that is reducing the flow rate. Can I open the inside of the first washer to increase flow rate and still allow proper filtration.

The question was asked but not exactly answered. Yes or no.. Does this filter out fluoride?

Asked by: DōTERRA life
Hello, Thank you for your question. No our shower does not remove fluoride. Due to the high flow rate of shower filtration systems and the minimal contact time with filtration media, this system is only certified for over 90% chlorine reduction. We do know that the media used can help reduce volatile organic chemicals, herbicides, pesticides and other chemical compounds, as well as lead and other heavy metals. Thank you, Aquasana Customer Support

Does this filter remove flouride?

Asked by: Chanel
Hello Chanel, Thank you for your question. Fluoride removal requires special filtration through a membrane. Our Reverse Osmosis System is NSF certified to remove over 95% of fluoride in your drinking water, as well as 87 other contaminants.

I can't stop the leakage between the filter and where it is attached to the metal screw in part.  It's not where the metal part attaches to the water source.

We have a regular shower head and a separate wand that has a separate plumbing outlet that is very close to the wall. We always use the wand and never the shower head. Can the filter be connected to the wand by the wall? Perhaps there is an adapter?

Asked by: TracyTP
go to a hardware store like Ace, with the wand
