Your CHF system,
simply explained.
A whole-home filter sits between your mains water supply and the rest of your house. Water enters the first housing, flows through each stage in series, then exits to feed every tap, shower and appliance in your home.
How water flows through your system
Each housing holds one filter or refill. Water flows through three stages in series — what each stage does depends on your setup. Together they treat the water before it reaches the rest of your home.
