Rated 1 out of 5 by from Filter Great, Want HORRIBLE I've been using the Aquasana Shower Filter for nearly 15 years. The filter is great and its effects are immediately noticeable. However, the wand they now use is horrible. When you turn the dial all the way to the left, it is supposed to come out like a rain shower. However, the design on this wand is faulty. The water struggles to come out in a rain formation. Instead it keeps wanted to go back to the massage formation, even though the dial is in the correct position. The original wand they used was perfect. But this new design, which Aquasana switched to a few years ago, is faulty.

Rated 3 out of 5 by from Prefer older elegant rounded design & materials I do not care for the most recent model: it does not have the elegant design of the previous models (this one is more angular and does not have that elegant curve), and the handfeel is not as good as the handle is angular as opposed to the previous rounded handle which had no edges. The material also looks cheaper. Other than that, it's fine and I will continue to use Aquasana.

Rated 3 out of 5 by from product great, however discount wasn't applied I have bought this product before, love it. however, i was granted a 30% discount and it was never applied. I receive emails daily still after my purchase for great sales, discounts but i do not trust they will be applied as it wasn't on my last purchased hence discouraging me to purchase again.

Rated 3 out of 5 by from easy to install My wife thinks she sees an improvement in her hair, what I noticed was a lot of charcoal come out of the shower head the first few days. The shower head could have a wider pattern.

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

Hi!  I'm a new shower filter user and my hair feels greasy faster than ever with my filter.  Is this normal?  Is my hair balancing itself out?

Asked by: Carrie
Hi Carrie, thank you for your question. Your normal water supply contains chlorine, which dries out skin and hair. When you take the chlorine from your water, it can certainly take a while for your hair to adjust. You may also notice that you do not need to use as much conditioner, and this may keep your hair from becoming greasy more quickly that usual. Thank you, Aquasana Customer Support

Hi I want to find out if your filters take out fluoride out of the water???

Asked by: Patty
Thank you for your interest in Aquasana! Due to the high flow rate of shower filtration systems and the minimal contact time with filtration media, this system is only certified for 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. That being said, we are currently unable to provide an exact percentage of these reductions. Thank you, Aquasana Customer Support
