A sealed bin does most of the work in a PETKIT box, but the N50 cartridge is what actively neutralises the odour that's left — and it's a consumable. These N50 2.0 cartridges are made for the PURA MAX and PURA MAX 2, removing up to 95% of ammonia odours with premium activated carbon. Each lasts about 30 days, so this six-pack keeps your box fresh for roughly half a year. Fitting takes seconds, and they're dermatologically tested and non-toxic.
