what is the difference between 3 systems & what size I need & what is the best

1- Deluxe Electronic Metered Demand ACMS Series Fully Automatic Softeners

2- ACMS Series Cabinet Style Water Softeners

3-Deluxe Metered Demand Water Softener and Activated Carbon Filter for Hard, City Chlorinated Water ( is this one Salt-free compatible when using potassium).

02.26.2007 We do not sell mentioned salt based softeners. Please see our NEW NO SALT softeners http://www.doultonusa.com/whole_house_water_filters/salt-free-softener.php

They are all metered demand regeneration softeners (the best). Cabinet style means the softener is inside the brine tank making it look as one piece and they all can use potassium for regeneration instead of salt.

The no. 3 is a softener and carbon filter combination.

Based on number household members and amount of bathrooms in your house we can recommend you the appropriate size for San Diego water hardness which is averaging 13-16 grains per gallon.
