When worn, it protects the player character from getting Poisoned by gas cloud attacks of Poison Holes and Stink Rays. However, it offers no protection against Poisoning via physical attacks of Poison Snakes, Poison Mosquitos, or Spider Warriors.
- WX-78 is immune to poison, therefore using a Particulate Purifier provides no benefits to it.
- Prior to the "Seas The Day!" update, this item was simply called "The Gas Mask", which functioned identically, bar for a slightly different recipe and texture. Its description was "Why smell bad smells?", and it cost 2 Empty Bottles, 1 Cloth, and 1 Jellyfish.
- The Gas Mask also had a voice filter which would increase the pitch of a character's voice when saying something.
