Rated 5 out of 5 by from Awesome buy! So glad I purchased this water filter shower head. My expensive blonde hair color was not staying bright, and I knew I needed to treat the water I was showering and shampooing with. Easy to install and have enjoyed the benefits.

Rated 5 out of 5 by from Love this shower filter! We have used Aquasana Shower Filters for years now. I'm so glad that they filter out the chlorine which can damage our health. We also use the filter for our kitchen sink so we don't have to drink chlorine, fluoride and lots of other nasties!

Rated 5 out of 5 by from Something new in the shower!!!!!! We have been dealing with Aquasana for the past three years, since we moved to New Mexico, from Pa. Our home had a standard Aquasana shower filter, which we changed it for the filter, with the wand. We have a guest bathroom, so I ordered a new one for that bathroom. The sales person asked me which one I wanted. Chrome, or white plastic, like we already had. For a couple dollars more I ordered the chrome unit. When my wife seen the new unit, she said that one is going in our shower, and the one from our shower goes into the guest bathroom. We both love it...

Rated 5 out of 5 by from Water filter I am very pleased with my water filter. It was economical and easy to install. The customer service is so excellent. My countertop water filter is more than a few years old, yet aqua sauna replaced for free the housing when it started leaking.

Rated 4 out of 5 by from Very happy I installed my filter and shower head about 2 weeks ago. I love the filter. My hair feels and looks so much better. My skin is also softer. I am very pleased. The shower wand however spays too far back in my shower is not adjustable but i can live with it for now.

Rated 5 out of 5 by from Life saver! I moved to Delaware from NYC a year and a half ago and that’s when I realized how different the water is in each state. NYC has amazing water but DE has very hard mineralized water. My hair started to change, it became dry and started to break and my skin became so dry! I used lotions, oils and nothing helped my dry skin condition. Someone suggested I get a shower filter, which I never heard of. I immediately started to research shower filters and Aquasana was rated one of the best! I decided to purchase the shower filter and it was so simple to install! I immediately felt the difference on my skin, it was like taking a shower in spring water! My skin is no longer dry and what a difference it has made when washing my hair! Before the filter I would wash my hair and apply conditioner and my hair felt like straw after rinsing it out. Now my hair feels silky after rinsing out the conditioner! I’m so happy I made this purchase, it has definitely changed my life!

Rated 2 out of 5 by from Not a fan I bought one and was then offered another for free (with a water for life membership). These are so awkward and barely adjustable. This shoots way over my head when installed in both of our showers. It’s not adjustable. It can’t be pointed down so the only option is to hold it, which then leaves only one hand free. A customer service rep said it will move after it heats up...not in any way that’s helpful to me. I could return it, but at my cost, or keep it for one replacement cycle and then cancel it. (Free is not free.) I’m keeping for now since we need a VOC filter, but if I was doing it again I would do more research and find one with better functionality.

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

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

Hi I want to find out if your filters take out fluoride out of the water???

Asked by: Patty
Thank you for your interest in Aquasana! Due to the high flow rate of shower filtration systems and the minimal contact time with filtration media, this system is only certified for chlorine reduction. We do know that the media used can help reduce volatile organic chemicals, herbicides, pesticides and other chemical compounds, as well as lead and other heavy metals. That being said, we are currently unable to provide an exact percentage of these reductions. Thank you, Aquasana Customer Support
