CleanView Mod (1.19.3, 1.18.2) is a Minecraft client mod which removes potion particles. This mod will remove any particles that were caused by potion effects from your character and other types of camera entities. However, the potion effects will still be affected. This mod is fantastic and should have been included in the game right from the beginning.
This feature is automatically enabled. However, you can toggle it by pressing a key. You can find this key under the Miscellaneous category. It does not have a default mapping.
