Keeps hair from getting build up. Works perfect on a cruise ship. After a seven day cruise, the filter was completely brown. Amazing what it gets out of the water. I am used to soft water so when traveling I always struggle with hard water making my hair feel like straw and greasy with all the build up it gets. Using this filter made my hair look and feel more like I was using soft water with no build up. I will be taking this on every cruise I go on.

Strongly recommend. As you can see in the picture, I am using three shower filters. The showerhead filter after the iblue link is totally white even though I have been using the iblue link for almost two months. The filtering ability of the iblue link is amazing!! Even if you are already using a shower filter, I strongly recommend using the iblue link filter.

Excellent shower filter for the skin! Over the years, I have tried several water filters for my shower due to skin issues, especially in the colder months. This iBlue Link is the first one where I could tell the difference it was making in the water immediately. After the first shower, my skin seemed smoother and wasn't irritated. I decided to use it for a week before leaving a review, so I can now say I'm definitely satisfied with this filter and will be giving some as Christmas gifts.

A MUST HAVE FOR YOUR SHOWER HEAD!!! I never expected my water to be so dirty. But after seeing the before and after I don't think I can ever go back to just using my shower head. Check it out and I am sure you will agree. Easy installation, No leakage and made out of very good quality material. The water pressure is fine as well! A+
