All units will perform well to a varying degree with any cation resin. The above table is strictly suggestive for obtaining optimal performance from your unit and extending the life of your resin bed.

When in doubt, ProSoft™ Premium is your best value for an all-around softening resin.

* Cabinet models can or should substitute ProSoft™ Fine Mesh resin for faster kinetics.

This table is based on SWT’s conventional wisdom only. Performance can still vary from factors such as high temperatures, oil in the water, silica or other local water characteristics. Contact your SWT representative for further assistance.
