Rated 5 out of 5 by from Awesome product I am already enjoying the benefits of my new shower filter after the first few showers! My hair is noticeably softer after only two showers. I was worried that my husband would not be satisfied with the water pressure coming out of the wand but I was pleasantly surprised. The water pressure is absolutely amazing; the filter does not hold any pressure back. Installation was a breeze. I did sign up for the filter savings program and now I do not even have to keep track of when to replace the filter. Great product!

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 this filter out iron?

Asked by: Dlife
I believe it does as I have a tub/shower and the shower curtain does not have that orange stain at the bottom. My hair is holding its color longer and my skin no longer itches like it use to. I notice right away that my color was not fading out so fast. I hope this answer your question.

Can I order 2 filters at a time and keep it to replace whenever its the time to replace the first one ?

Asked by: Jaga
You probably can, but I have found that the company sends me a new filter every 6 months and I know it's time to change it.  That works great for me plus I don't have to have storage place for the extra filter.

What is the price for the chloramine shower filter?

Asked by: DebbyA
Hi Debby, our chloramine systems are the same cost as the chlorine systems on our website. Just give us a call at 866.662.6885 so that we can place that custom order for you. Thank you, Aquasana Customer Support

The design of this unit puts the shower head at a strange angle so that it actually almost hits the upper wall at the other end of the tub. The angle cannot be changed to lower the shower head because the filter is in the way. Suggestions please.

Asked by: wynnie591
I installed a longer threaded shower pipe than the original one that comes from the wall. Longer ones are curved downward significantly greater that the standard  installation pipes. It gave more room for the filter to be installed in the correct position & allowed the shower head to be lower & positioned correctly too. And gave me back the space to put the shower caddy back over the shower pipe too.

In our RV, there is no shower head.It has a handheld sprayer that attaches to the faucet below.Will this filter work with this type of setup?

Asked by: traveler
No it won't. I've had 3 RVs with the hose connection by the faucet. Top or bottom. The filter and the connection are 2 different sizes. The weight of the filter would break the fitting anyway. All you need is a good outside filter.
