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.

Rated 5 out of 5 by from Hair I just wanted to say that my daughter has very long, think and wavy hair. Without the aquasana water filter in the shower she ends up with uncombable knots in the middle of her head. With the filter her hair comes out smooth and unknotted. This is a lifesaver for our family. Plus as the advertisements say, it really does allow you to use less shampoo and conditioner.

Rated 5 out of 5 by from As advertised After a very simple installation the shower filter was purged and put to use. We were delighted with the great water pressure, no slack off there at all. My wife's first impression was how much better the water felt and smelled. She liked the shower filter and the wand is nice to use and nice to look at.I had to concur and now we are contemplating a whole house system. Nice product....as advertised

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

Will you ever offer the shower filters and Wand in Black? All our bathroom fixtures are black, and the white and chrome you offer just do not match and clash. So I am hoping both the filters and wands will eventually be offered in black.

Does the coconut shell carbon filter work in hot water conditions? Does this filter out other impurities other than chlorine?

Asked by: LauraM
Yeah the shower filter has to be able to use hot water. I usually buy my filters for the last two years off the actually Aquasana site but just recently discovered Amazon sells it. With exchange the filter for me worked out cheaper but the kitchen sink unit(counter top) was double..just go on their site, you will find your answers as they have videos and detailed list what the filters protect you from..all I can say for sure is only one of their expensive units protects you from fluoride. so if fluoride is a concern do lots of research. I have used Aquasana kitchen sink filter and shower filter for two years. Until I got this I didn't realize how nasty city water is and how good water can taste but I don't get six month out of my kitchen sink unit as their is five of us drinking the water and using it to cook. I get about four months and you can start tasting the chlorine so you know it is running out.

Are these filters recyclable?

Asked by: Jean-Francois
Aquasana's website states that the plastic filter parts can be recycled. It also says the carbon filter can be composted. BUT, I read an article that said to never, ever, put the carbon filter in the compost or garden. All you are doing is putting all the bad contaminants in the carbon back into your soil! Who would want to do that?? Call your local sanitation department and ask them.
