We have real hard water on a well.I am ready to bite the bullet after five years and put in a system before it destroys all our fixtures and makes it more enjoyable to drink.It actualy test potable and taste good but you can see minerals in the water,like if you had a glass of ice water by your bed you dont want that last drink in the night because in the morning you can see clingy mineral type stuff.I've put in a few filters over the years (non-salt)and have not been happy with any,except an EWS charcoal filter.It's pretty darn expensive but like I said I am ready.Anybody install any others that stands out head and shoulders above the rest(non salt).
