Aquasana Shower Filter Replacement Cartridge AQ-4125 (4-(Pack))

I have been using these filters for many years. I could not figure out why my blonde hair kept turning a muddy brown. I would highlight my hair and then within a few weeks it was brown. I finally went to a color specialty salon and they told me it was most likely my water. I told them I bought an expensive water filter for my shower. It was then that I realized these filters have copper in them. If you google copper and hair color you will see it ruins hair color; mostly blonde highlights. These aquasana filters are now made with copper. If you color your hair this is not a good filter for your hair. I have since bought some product to strip the copper and other minerals out of my hair and am switching to a shower filter with no copper. My blonde is staying blonde now.

I bought this filter because it had great ratings and I wanted something that did more then just filter chlorine out. I am crazy about researching things before I purchase them. I really liked the multiple filter steps that this product has. My problem is hard water and the mineral buildup that ends up on my hair. This in combination with special shampoo and conditioner has helped me so much. When you first put it on and run water through it, it comes out black at first due to the carbon. It is supposed to do that and they say you can collect it and put it in your garden as it is good for it. After less than a minute of running it it will be clear. I also purchased this with the adjustable shower head which has different spray options if you like more or less pressure. My only drawback is the size of the filter. Its not huge but it does make it so I cannot adjust the angle of the shower head to be right over me so i have to stand a little further out. But it's not that much of a big deal to me.

Ive had this filter on my shower for several years. The filter removes the chlorine in the water and leaves my hair soft and healthy. It helps maintain the color since my hair is colored treated.The problem is that it is very difficult to unscrew the filter from the shower head. Since it is a filter, the connection needs to be secure. When it is time to change the filter, I need to use a large pipe wrench to unscrew the filter from the head. This is difficult for me since I have arthritic hands and my husband has to do it. Once it's on,I love it. The shower head was expensive, so I am motivated to keep it and replace the filters instead of buying something that's easier to install.

Notice a big difference in the quality of water since I started using this. Skin is much smoother, less dry, and no longer itchy. A warning: when you install a new filter, the water comes out black for a bit. Make sure you have something to run the water into. I tried doing it in the tub without a bucket or such, and the tub became stained. The stains weren't permanent - I was eventually able to get them out - but it took a while.

Nice for people with gross water. The municipal water where I am tastes gross and I don't want it on me in the shower, so I'm that guy. I mean, what if I want to gargle in there? Gross water begone. Lasts a long time. They say replace them every 6 months but I typically go a year.

So the instructions tell you to remove everything (the filter/housing/adapter/shower head/everything) from the shower pipe, and then replace the filter, and then put everything back together...well that wasn't why I bought this. I bought this with plans of not removing everything from the pipe.I setup Amazon to automatically send me a new filter every 6 months.When it came time to replace it it was stuck/frozen in place...well darn...So I bought a EcoPure EPUSW Whole House Water Filter Universal Strap Wrench.I used my new strap wrench to carefully (trying not break the plumbing) to remove the filter. It worked great.Then the new filter easily screwed on.The filter itself it great. Great water pressure and my hair feels healthier.

THEY ONLY LASTED 4 WEEKS. CONTINUED TO PURCHASE FOR THREE YEARS.FINALLY BOUGHT A WATER SOFTENER. BEST DECISION I EVER MADE. I HAD TO BUY DOUBLE ORDERS TO KEEP OUR HAIR FROM BEING SPONGY. FOR TO SHOWERS. THE TOPS WOULD CRACK, SOMETIMES YOU HAD AN EXTREMELY DIFFICULT TIME UNSCREWING THE TOP TO REPLACE THE NEW FILTER. THEY WORK GREAT, BUT ONLY FOR A VERY VERY SHORT TIME!

I've been using these for years. I purchased the whole unit with shower head initially, and replaced it once. But each year, I only purchase replacements, for both bathrooms. These prevent the skin and hair from drying out from chlorine in the water, and they are very efficient. You will definitely notice the difference in your skin and hair. Highly recommended.
