Check fitment on the card before ordering
Replacing on schedule, not on failure
A filter fails quietly
Output falls before anything stops working. The unit tracks each cartridge's life so replacement is a reading, not a guess.
Order ahead of the date
Delivery is three to five working days. Your account raises the reminder early enough to order without a gap.
Fitting is free in warranty
You can seat a cartridge yourself in minutes, or have an engineer do it at no cost while the system is covered.
