How to tell when it's really time
This is the stuff our customers ask us most, after 20+ years and [thousands] of systems sold.
Six months is a guideline. Big households and hot, long showers use cartridges up faster. The real test: grab chlorine test strips from a pool store and test the shower water. If chlorine is back, swap it.
