One of the most important things you can do for hair is to wash it with filtered, chlorine-free water. Your hair will be noticeably softer and shinier, your scalp will be healthier and your color will stay true and last longer.

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.

Rated 5 out of 5 by from Love it I don’t smell chlorine anymore. Makes my skin feel better and my hair is softer. I like the hand held shower makes bathing animals easier. I highly recommend this item if you have allergies with chlorine.

Rated 5 out of 5 by from Bye bye hard water! We recently bought the Aquasana shower filter plus one for a friend and so glad we did. No more hard water stains on the shower walls or door plus softer skin and hair. It's easy to install and works great. When we contacted Aquasana with a question, they were quick to respond and very helpful.

Rated 5 out of 5 by from Love it! Installed it beginning of January 2018. LOVE IT!!!! After 2 weeks or so, the difference can be felt and seen. Skin isn’t dry like it was without the filter, a small amount of shampoo goes a long way, no more dry scalp/flakes... couldn’t be happier!

Rated 2 out of 5 by from Not Sure... The apparatus itself is fine, but not sure about its effectiveness for more than a couple of months. It is used by myself and my husband only. The water felt different in the beginning. It’s hard to believe that it has a six month time frame. Our next filter will come automatically so I will give it one more try before discontinuing.

Rated 4 out of 5 by from Takes too long for water to warm up I’d been mean to try a shower filter for quite awhile due to concerns about chlorine in the water and my itchy skin. It works fine but takes a long time to get the water to warm up, then it’s too hot when I’m trying to add cold water.

Rated 5 out of 5 by from Great product I bought this shower filter after going away & experiencing a different water out of nyc & was amazed at how terrible our water was & did some research and came across great reviews of Aquasana so I invested in one & it’s the best thing I could have done, my skin isn’t dry & Irritated any more, I don’t have to use so much soap, shampoo & lotion

Rated 5 out of 5 by from Great value for the quality I have used my shower head with extended hose for a month now. It was easy to install and does the job. The water smells clear of chemicals as well as I know that what I bathe in and drink are now cleaner which makes anyone feel better. The shower head is smaller than some other heads but if you want to save water, which is a responsibility in southern California then win win

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 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: https://www.aquasana.com/drinking-water-filter-systems/reverse-osmosis-claryum

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

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
