Rated 5 out of 5 by from Love it! I purchased this brand and unit after my other filtered hand held showerhead broke. It was the clunky type that had the filter in the handle, which made it not only heavy, but inefficient. I’m glad it broke, because this one is fantastic! It has great water pressure and the range of types of water spray is great. The only negative is that it leaked from here the unit screws into the inlet pipe that comes from the wall. My husband turned the filter unit at an angle to get it to stop. It gets the job done, and I love how much softer my skin is now and the water feels great that comes out!! I’m so glad I purchased this!!

Rated 5 out of 5 by from Honest review I ordered the Aquasana showerhead filter because I was moving out to the country where we have rusty well water. I absolutely love it!!! It works better than I ever imagined!!!

Rated 5 out of 5 by from Quality Product The instructions for installation made it a simple process. I immediately noticed that the water is softer and it did not affect the pressure at all. Excited to see if this leads to any skin benefits in the near future.

Rated 5 out of 5 by from Nice Showers! My fiance installed the shower kit and was the first to test it out. Priming the filter was simple and fast; he did it in the shower stall. Both of our skin issues have been alleviated (mine went away completely) which leads me to believe that our sensitive skin was reacting adversely to the pollutants in our city water. This is our first purchase of this kind and from this company, so we immediately signed up for the continuity program. What surprised me the most was the customer care: Brent reached out to save us more $ by informing us we'd bought during a promotional sale. We ended up receiving a countertop model of a water purifier unit. That has yet to be installed but once it it we will use it a while and publish the review. Thanks!

Rated 5 out of 5 by from Excellent product - Easy to install. This product fit my needs perfectly. It delivers clean water in my shower and was very easy to install. Fool proof actually. The water pressure out of the hand held device is perfect. The handle is very light and easy to use when removing to wash hair, etc.

Rated 5 out of 5 by from Huge Improvement using your well water filters When I initially called Aquasana I didn't think that they carried filters for well water. But, amazingly, they do! The well water filters are not advertised on their website. What a wonderful difference in my shower now. Soap really suds's great now, skin feels really clean and without any residue from the well water. Also, hair is shiny once again and much more manageable. Also, utilizing less product. This is a great purchase and worth every penny. I am a renter. But, if I were the owner I would invest in the whole house system. Well water has different things in it over city water. It does not have chlorine or fluoride but it has iron and other contaminants. Aquasana is the only shower filter that I could find that has well water filters to remove iron plus other contaminants known to well water.

Rated 5 out of 5 by from Awesome Product The filter was easy to install but the metal connector was hard to attach to the inflow pipe. It was rather slippery. Other than that, the water quality has improved and the water acquired a better smell. It also became softer on the skin. I highly recommend this.

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

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!

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!

Does the hand held wand angle down ? I have a very small shower stall in my apartment and how the angle of it appears it will shoot water at the upper wall.

Asked by: Amy Marie
The angle is adjustable to a certain extent. The connector between the filter and shower head can be adjusted to angle up or down, but I think the furthest down is about a 45 degree angle from the vertical or horizontal axis. my shower is only about 4 ft and it’s fine.
