I recommend Nova - reasonable cost, separate components for maintenance, responsive on service needs.

We installed Nova filters & water softener for the whole house 7 years ago when we moved in. The water softener is potassium based vs salt based. The potassium softener is healthier and the discharge is not harmful to landscape/lawn. Unfourtney potassium is more expensive than the salt.

Our water has a hardness of 15 graines which is extreme. The Nova system brings it down to 0 graines. When we moved in 7 years ago (house 10 years old at that time) we noticed all the water fixtures, toilets, and mirrors (splatter from the sinks) had noticeable calcium deposits which we had to scrub off with CLR. That is not an issue now.

Probably the biggest benefit from the Nova system is the water taste - there isn't any!
