At an affordable price, the SoftCell softener provides a simple solution to the problems associated with hard water used in recreational applications. Simply installed between the hard water source supply and your boat or RV, the unit requires no electrical power and has no moving parts to repair or replace. You can fill your potable water holding tanks, or use a hose directly from the softener to wash and rinse without the stains and spots from rusty and hard water. SoftCell’s portability allows you to take the benefits of your home water softener with you as you travel or cruise from place to place
