Rated 5 out of 5 by from aquasana shower i really recommend this shower aquasana to all my family, my skin it feel wonderful and also my hair

Rated 5 out of 5 by from City Shower Water caused stinging sensations Needed a filter to address this startling problem ASAP. Read up on filters and found that the best solution was a dual filter that contained a charcoal component. Aquasana had a sale at the time so I decided to try their shower filter and glad I did. Product has reduced the water irritation by at least 75% so now I can take a shower with much less suffering. What is going on in the City Water is very concerning so be mindful of what quality of water you are bathing with wherever you live.

Rated 5 out of 5 by from LOVE THIS FILTER! Installation was super easy! Noticed a difference in how my hair felt after just a couple of days - I didn't realize how much the city water was drying out and stiffening my hair. After a few weeks we can tell a difference on our skin - not nearly as dry. I wish I had bought this sooner! I recommended this item to my sister, and she is having the same great results.

Rated 5 out of 5 by from THIS SHOWER FILTER IS AMAZING!!!!!!!!!!!!!!!!!!!!! I had to write this review after just two days of use because the difference to my hair is amazing. I have been dyeing my hair for years and it's dry, brittle, broken and not in good shape at all. Even after using conditioner I would still have to use a detangler comb and detangler product to get through my hair. After just TWO DAYS of using this shower head, my hair is shiny, soft and I have not had to use a detanger comb OR product. I picked up my brush and it went straight through my hair. I expected some difference in the water but I really did not expect such a dramatic difference to my hair. I am SO glad that I made this purchase. Oh and it was easy to install too so that was an added bonus. Plus it has a nice massage feature and has really good water pressure. There is not one negative thing I have to say about this shower filter.

Rated 5 out of 5 by from Goodbye dry dull skin! I have been using this for 2 years and I hate showering anywhere but at home now. Getting the chlorine out of my shower has made a huge difference in my skin, even in the winter. Hair needs less conditioner because it's not getting stripped and color lasts longer. Also, no more funky orange rings around the drain.

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

how often do i have to change the filter

Asked by: moti
Hello Moti, Kindly keep in mind that the Shower System has been rated to last 400-10 minute showers or 10,000 gallons of water usage. For a household of 3-5 we recommend a filter change every 6-months. However, for a household of 1-2 the recommended time frame of 6-months can be extended to a 12-month interval if needed. Thank you, Aquasana Support

I installed my shower filter and white wand. Will the white hose eventually straighten out or will it always be kinked out?

Asked by: Shavey
I have the same product. The hose has never straightened. That said, I did not take the time to lay the new hose flat across a table before installing which you may help. This is a nice product. I would warn you that the small part that holds the removable shower head in place has broken on mine and I need to have it replaced.

Is this a water filter and water softener ?? Thanks

Asked by: Rachel S
Not a water softener it takes out as many impurities as the filter will allow and this makes the water not as harsh on your skin.

Asked by: SamB
I have used the Aquasana shower filter for over 10 years and found it to be very good in removing chloramine from the water. Immediately noticed the difference in my skin and hair. Would recommend it to anyone.
