No more cramps
My mom sufferes bad leg cramps due to a couple issues she has with auto-immune things. When she drinks the water from the cerra filter, they are almost non-existant. The other day she was doing some work outside and when she drank water, she didn't use the filter because she was in a hurry. She had leg cramps that night. It's shocking what a difference the filter makes for her.
