Review: This filter does the job - I’m really happy with my purchase! The installation was a breeze, and I can already notice the difference in the water. It’s also great on my skin it feels real soft after my showers.
Review: Makes a difference I won't go without! - I did much research before deciding on the Water Chef shower filtration unit. To say I love it is an understatement, I refuse to live without it. I live in a town where the water is hard and full of minerals. Before installing the Water Chef filter I'd find my skin felt itchy after showering and my hair felt dry after shampooing. I thought to myself if I filter the drinking and cooking water it only makes sense to filter the water I bathe with. When it's time to replace the filter I just unscrew the bottom of the housing and pop the new one in. You'll feel the softness of the water immediately. Do run the water for a bit after installing your filter till it runs clear. This only takes a few moments. It's hard to describe the difference in how the water feels, you just need to experience it. The company and the customer service is wonderful, they stand behind their products. So if you want glossier hair and softer skin after showering check out Water Chef. I'll know you'll be as pleased as I am.
