Buy ahead, pay less
Cartridges ship flat and cheap, so stocking up by the year saves you money and a few trips to the checkout.
Good questions.
How long does each cartridge last?
About three months of typical household use. So a year is 4 cartridges, two years is 8, and three years is 12. Heavier use shortens cartridge life proportionally.
How long do unused cartridges keep?
They arrive sealed, and the carbon inside is dry, so unopened cartridges sit happily in a cupboard. The three months is time in use — the clock starts when you fit one, not when it arrives — so buying two or three years ahead doesn't cost you any of their life. Keep them somewhere cool and dry, out of direct sun.
Will these fit my filter?
If it's a NERŌ Kitchen Filter, yes — every one uses the same cartridge. Unscrew the body, drop the new cartridge in, screw it back on. No tools, no plumber.
