Great filter, does the job

The filter itself is easy to install and I have seen a a noticeable difference in my skin and hair since I started using it. I joined Water for Life and I appreciate the filters just coming automatically in the mail just about the exact time I need a new one. Do not purchase the showerhead though, it's not neccessary and honestly I wanted to love it but it is terrible. It only has a super spray function or a heavy drip. I miss my rainshower head and will probably go back to it.

Great filtration

I am enjoying my new filter a lot. We are on well water so I have a shower head filter, my hair feels like it's actually getting clean now, and the soap fully rinses off of us.
