After purchasing and using the KIT,  purchasing a 32 fl oz (946 mL) container of Salt-Away Refill Concentrate is a recommended choice, depending on frequency of use, area to cover, and economic considerations.

No need to purchase the Mixing Unit again. Part Number: SAM (SAMI for International customers).

Mixing Units can be ordered independently of the Kits. Ask your favorite store to inquire about this option.
