We were shopping around for a home water purification system on and off for a few months as I was tired of lugging in RO water jugs from a nearby store. We checked out a few other brands. Then we called in Aquasoft, made an appointment for their sales guy Donald. We liked what he had, ended up buying the whole house system as well as the reverse osmosis system under the sink. The installer Bill was a very nice guy too. Thanks, Aquasoft!
