Rated 2 out of 5 by from Good Filter, Bad Flow After much research I purchased this filter confident that it was one of the best as far as its filtering abilities. Unfortunately after a few weeks the flow is down to a single stream of water. This is my third Aquasana and I’ve had the same problem with each of them. As much as I like what it can filter, I have to find another brand.

Rated 5 out of 5 by from Great Experience I really love the new shower system. The water feels softer. I am not experiencing the dry skin itch that I had before on my shins. It was so easy to install and it doesn't leave the water spots on my glass doors.

Rated 5 out of 5 by from Best shower ever! What a difference! The addition of the Aquasana shower filter and handheld wand has created a wonderful shower. I no longer smell the chlorine in the water, the water feels softer and less harsh than my previous showers without the filter. Great product!

Rated 5 out of 5 by from Great shower with great features!!! I have 2 of these shower headsets and both my husband and I love them!! They are versatile with multiple spray options from soft to hard. I love ❤️ that the chlorine is filtered out leaving my skin soft and not itchy. The handheld feature is great because my husband is handicapped and that makes it easy for him to shower easily without a lot of help. He also likes the variety of spray options. Also this shower head does not lower the water pressure from the original amount which was very important to my husband since he likes the heavy or firm pressure and was concerned that the pressure would not be the same with filter. It’s a GREAT SHOERHEAD!!!!....

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
