Rated 4 out of 5 by from Love knowing I have better water quality. I love the shower filter and knowing I have much better water. I couldn't use the hand held part because it was too high in my shower.

Rated 4 out of 5 by from I can take it anywhere! I bought this 3 months ago, but waited till I moved to my new apartment to install in my shower. Maintenance did it without any problems, although I probably could have. I did need to get a new shower caddy, one that had enough clearance space for the filter.

Rated 3 out of 5 by from Disappointed My original shower filter failed to work well. It was old, so I ordered a new one. When we installed it, it was leaking at the hose join and tightening did not help. We discovered that it came missing an important washer. Luckily we had some washers and were able to find one to fit. Since then, there are no more perceivable leaks. A new product should come in perfect condition, so this was a disappointment.

Rated 5 out of 5 by from Great shower - easy installation I have used this shower wand and water filtration for almost 10 years, and I wouldn’t use anything else. The wand head has several water flow combinations, and installation is easy. They also send me a new filter every six months, som8 don’t have to think about replacing the filter. Great product!

Rated 4 out of 5 by from Silky skin feels good Wanting to continue my efforts in healthy living I began researching shower filters ...drawn by the reviews and at the time the sale on the aquasana; I made this my choice. I can't say enough of how great it feels to be showering in water that is being filtered and purified by aquasana. My dogs like it too!!!!!

Rated 5 out of 5 by from Chlorine free Every time I took a shower I could smell chlorine. I purchased and installed this shower filter with shower hose and no longer smell chlorine. This is an easy install with simple instructions. I am a woman 71 years old and did it myself!

Rated 3 out of 5 by from 1.5 year lifeline This is the second one I bought. The light spray stops working properly after 6 months and it gathers so much bacteria by 2 years you'll want another one. Not long lasting.

Rated 5 out of 5 by from Shower filter and chrome wand We love the system of filtering our water. All ready I am feeling the difference in my hair, it is softer and shiner. One obstacle we are working on and are open to suggestions. I am not very tall and my husband has PERMEANT BENT LEGS DUE to Cerebral Palsy, creating a challenge to reach the new hight of the wand in its holder. One other feature, we wish could be corrected. The wand holder is difficult to remove the wand at this new hight. A snap in design could be the answer. The plastic construction has already broken. A metal holder would be a welcome advance. Our many thank you to the company for replacing it with no extra charge. With God's greatest blessings Sincerely Matt and Loretta

Rated 4 out of 5 by from Soft Hair This product has already shown a major difference in the softness of my skin and hair. The only thing I would change on this product is the flexibility of the wand so it does not stick out into the shower area while on the handle.

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 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. Feel free to check out our RO system here:

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
