It is also a 6-month cartridge, so the cost repeats twice a year.",

The NSF/ANSI 53 and 401 claims rest on a reproduction of NSF directory entries checked 2026-09-30; neither live listing names this cartridge today, so treat those two claims as unverified and check any cartridge in the live listing under its own code before you buy it."
