So far so good with this vita fresh shower filter. I've had it for a week now. It installed easily and looks really cool in the shower. Plus it came with 2 vitamin c refill tubes(3 total). Shipping took just under 1 week. I'm surprised there aren't more reviews. makes me wonder why more people aren't buying it. Regular water filters can't filter out chloramine, which is the most commonly used disinfectant in the water supply in America these days. At least the last 2 cities i've lived in(dallas and San Fran) definitely have had it. If you're getting dry scalp, this might be your solution.
