Rated 3 out of 5 by from Less dry skin - awkward in my small shower For the price, the product is worth it regardless of the cons thus far (I've had for 1 month). Don't forget to buy plumbers tape because all new shower heads leak. The hose connecting to the shower head are fussy and if it turns 1-8 of an inch it will leak, which is easy for me to do. This system makes my shower head higher than it was before, and I'm short, and so I need bring it down frequently, which causes it to sometimes leak when I turn or accidentally unscrew the head. Still, my skin and hair aren't so dry anymore and I feel comfortable staying in the shower longer without fear of chlorine being absorbed into my body then entire time.

Rated 3 out of 5 by from Haven't noticed a difference I purchased this almost a month ago and it was easy to install; however I have not noticed any difference in my water, which still feels hard to me. My hair hasn't become softer or any better than before and my skin is still as dry and flaky, so it doesn't seem to be doing anything for me. Not sure if I will buy any replacement filters after this one runs out, since I haven't noticed a difference. Also, the water pressure is REALLY low now that I have installed this. I used to have great water pressure but now it is slow and feels like I barely get any water on me in the shower.

Rated 5 out of 5 by from Provides a fresh, enjoyable shower every time Have used an older model Aquasana shower filter before which I loved. Saw a great deal over the holidays for this and decided it was time to switch to the newer model and I'm glad I did. Works perfectly with a good feel to the shower head. I'm tall and most shower heads are too short for me, but using this type with the hand held wand seats the shower head a little higher than a standard one norma

Rated 5 out of 5 by from Love showering in clean water My bathroom use to smell like a chlorine filled swimming pool. Now there is no smell at all. I feel soooo much better taking a shower and bathing my children with this shower head. My hair has also improved. It feels less damaged and does not tangle as easily. When I first moved into this house my hair immediately became damaged and matted just after my first shower here. Thats how much chlorine and ammonia is in the water here. With this shower head my hair has improved greatly.

Rated 4 out of 5 by from Aquasana meets shower filter need Purchased the Aquasana shower filter to fill bath tub with filtered water for salt baths. So far I've only showered with it. I selected the wand attachment option which compensates for the limited range of motion of the shower wand while it is docked due to the bulky filter mounted behind it. The water pressure is even and strong, and the wand has an adjustable pressure setting to power wash if needed. The hose is made of a tough rubber which doesn't hang straight down while the wand is docked and sometimes causes the wand to rotate. I haven't tested the water quality. I basically trust that the water is being filtered and will probably notice that it is once I change the filter, a filter good for six months. Overall I'm happy with this purchase. Also installation was a breeze being completed in about 25 minutes including catching the carbon water from the filter on first use.

Rated 5 out of 5 by from Softer Skin & Shinier Hair I recently started dry skin brushing and wanted to improve the quality of the water in the shower. From the very first use, I noticed my skin was softer and my hair was shinier. My husband said the water no longer stings his eyes. Even our dog is softer and shinier after her bath. I installed them at our home and cottage. The well water at our cottage turns our skin orange and does bad things to m

Rated 5 out of 5 by from Awesome!!!!!!! I am enjoying my water filter and so is my hair. I have hard water in my home, but my husband would not let me get a whole home system. I opted for just the shower system. The feel of my water has changed. My water used to feel heavy, now it feels soft on my hair and body. I look at my shower curtain and I have no residue on it. It has been great. My shower is easier to clean without the hard wate

Rated 3 out of 5 by from Cost-Reward Difficult to install due to angle-size of filter housing. Showerhead and hose that came with filter is low quality. I installed a quality replacement but had trouble. It is not right, but I made it work. Purchased this filter to help with chlorine reduction. Can not smell the chlorine now, but my eyes are still irritated and red when I get out of shower. Simple charcoal household filters worked be

Rated 4 out of 5 by from Great Filter This Filter is used in a bathtub shower. I wish I could install his filter directly to the bathtub faucet to have filtered water for my baths. I would be willing to pay extra$$ for a better cord (white) between the filter and the handheld wand. The wand is light which is a positive thing, but the cord is too rigid, when water is running through it. Also the other shower that we have is Grohe, unfortunately this filter is not comparable with Grohe assembly. Any suggestions would be appreciated.

Rated 5 out of 5 by from So far, so good! I purchased one of these shower head filters and got one free! That's a great way to start. I have only had this product for a month but I already see a difference in my hair and skin.||We recently moved to a new town and were met with harder water than we were used to. My hair became frizzy and straw-like and my face started breaking out. Since using this product my hair is already back to normal

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

We recently purchased two shower filters but it has been brought to our attention that our water company uses chloramine rather than chlorine. Do these also eliminate chloramine?

Asked by: LivingOrganic
I hope you have been enjoying you shower filters so far! Unfortunately these systems are only intended for use on chlorinated water. They have certainly been helping with your water quality, but because chloramines are such a harsh chemical, the 6 month lifespan will most likely be cut in half. We do have a shower filter that is designed to be used with chloramines. Please call our service team at 866.662.6885 and anyone here will be happy to assist. Thank you, Aquasana Customer Support

Does it filter Lead and other metals too?

Asked by: Nirel
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
