I have always had very hard water and I have always hated it. So I personally couldn’t imagine not using a water filter. I have one of those systems that filters your whole house including the shower heads. What was even better is that it really didn’t cost me that much. I thought a whole house filtration system would be very expensive but in the end it didn’t come out to be nearly as much as I thought it would. Though even if it had been more it would have still been worth it for the clean water we now get.
