Set of P2 cartridges with filters for its respirators, but I personally checked and tested that these can be used with 3M 5000/6000/7000 series respirators. Similar 3M replacement cartridge with filters sold for $26 at Bunnings, which are sold out in store and online.
Safecorp P2 Replacement Cartridge w/ Filters 2pc for $0.80 set
Great deal. Ordered the cartridges. Expect to get it cancelled though…
