Questions & Answers

I have been using this filter (aq-4100/4105) for years, because I'm on a well that is heavy in iron. My first line of defense is a whole house softener, with this being secondary. Are you now saying this is not the correct filter for hard well water?

Asked by: AMU*
I have very hard well. water with no softener installed. Works great for my shower. Only issue is it does not last very long. Because of how hard my water is. But for first 2 months its the difference between night and day. I would say yes this is the correct filter for hard water. And with a softener installed up stream. This filter should last a lot longer then it does at my house.

How do I know when a new filter for my shower is needed? When I turn it on the water runs dark for a few minutes. Is that normal?

Asked by: bella
Hi Bella, There are a couple things that can cause that surge of dark water when you turn the system on. If it is a new filter, then this is just the excess carbon being flushed out, and should resolve itself after a week or so. If it is an older filter, then it is just sediment that has been trapped inside the filter. When you turn the water on, that initial surge of water can force that trapped dirt out. We suggest changing the filter every 6 months to ensure that the filtration media does not start to degrade. Thank you, Aquasana Customer Support

are all the replacement filters the same price.is there any kind of penalty for stopping auto filter delivery.

Asked by: sc64
Thank you for your interest in Aquasana! We currently only have 3 types of shower filters. The one which can be purchased online is intended for use with water treated by chlorine. If your city uses a combination of chlorine and ammonia (chloramines) or if you are on well water, you can call into 866.662.6885 and request a special filter be sent out. All of these filters will be the same price on Water for Life ($44.62). You can cancel this program at any time with no penalty. However, if you enroll in the program with one of our BOGO offers and receive a free product, we will ask that you either send back or pay for the free product if you cancel prior to your first Water for Life shipment. Thank you, Aquasana Customer Support

Premium Shower Filter Replacement Cartridge is rated 4.7 out of 5 by 913.
Rated 1 out of 5 by from Cheap Plastic Broke The 1st time I attached the filter to my shower pipe from the wall, not after time from use, it cracked & leaked. The threads are cheap plastic.

Rated 5 out of 5 by from The best Been using this for years. The best decision I've ever made

Rated 4 out of 5 by from Shower water feels clean and pure. The shower water has a very clean and pure feel to it. The only downside to this product is that the filter housing, which attaches directly to the plumbing pipe outlet, tends to crack where the neck of it attaches to the pipe. This neck appears flimsy in design, and is made of plastic. This problem has happened frequently, usually after about three filter replacements have been made; about once every 1.5 to 2.0 years of operation. I suggest using a metallic neck in place of the easily cracked plastic in a new design of this housing.

Rated 5 out of 5 by from Can't live without it! I love this shower filter. Without it the water smells awful and very chlorine-y. This filter is so easy to install, as well as replace, although it lasts a long time. My skin and hair is softer and I feel like it keeps more of it's natural moisture. I've used it in NYC and then when I moved to LA, I'm not outside of LA and the water is all the same. When I've moved or when I travel and have to use municipal water and then come home to my filtered water and I remember how awesome it is and I'm grateful to have it.

Rated 4 out of 5 by from like rainwater Have used these filters for years now -- they do a great job, better than the old shower filter system we were using. The filtered water is so much better for my skin and it also makes my hair softer and fuller. My only complaint is that the installation is a bit of a headache -- you have to remove the whole filter assembly from the fixture before installing the new filter, and this takes some strength since it's tightened firmly to prevent leaks. But the results are worth it!

Rated 5 out of 5 by from Can't live without these shower filters I've been a long time user of Aquasana shower filters and they are the best I've ever found. I regularly get hair colour and highlights and my hair stylist regularly comments that my colour is very well preserved. There's no dullness or fading. I credit the shower filter for this. I used to experience chlorine ring in my shower stall but this no longer occurs and there is no chlorine odor. My skin and hair have improved considerably since I started using these filters.

Rated 5 out of 5 by from I will continue to use, so far I love it I live in Florida so out water is very hard, I started using Aquasana under the sink for my drinking water several years ago but then learned how much of the contaminants you absorb through your skin while in the shower. This filtering system has made a huge difference in the way my hair and skin feel after taking a shower. I take advantage of the filters for life so I do not have to remember to order, they just come when I need them.

Rated 2 out of 5 by from Grrrrr . . . install nightmare. I originally bought the shower-head, spray hose, and all attachments as well as Filters for Life. The filters are great but the rest of the package, which should be designed to cope with hard water and difficult conditions (if you have great water, why would you buy this?) is indadequate. I dread replacing the filters an now, after 3 years, need a new shower-head, new attachments, new hoses, whole works. Irritating for the price.
