The obvious advantage is the cost effectiveness of the salt-water chlorine generator. For example, you spend $300 per day on chlorine for a commercial pool. Over a period of five years you will spend in excess of $500 000. An equivalent Commercial System will cost under 1/4 of that amount. The system would pay for itself in two years. AIS Also provides two year warranty for commercial chlorine generators!

Aside from the initial start-up, salt is only added to replace what is lost due to splash out, backwashing, pump out or draining. Cell (electrode) life is up to 5-7 years. The only other cost is for electricity and that is very modest.
