ARC Raiders‘ progression is tied to various items, which often take a long while to find and discover.
The currently-ongoing event, Flickering Flames, also requires specific items to be advanced, including Water Filters, which are tied to its fourth stage. Water Filters also have other uses and are generally a valuable item, one you can either sell or keep, depending on the situation.
So, here’s how and where you can find it.
Where to find Water Filter in ARC Raiders

Water Filter usually spawns in Industrial loot zones that can be found on just about every map of the game. However, I’ve had a lot of luck with them on Dam Battlegrounds, specifically in the Research and Administration building (itself quite a good spot for valuable loot overall). Try to loot every single container you come across in the building, and odds are you will get at least one Water Filter, if not more.
Additionally, Water Filters tend to spawn in Security Breach boxes. These can only be opened if you have the necessary skill unlocked from the Survival tree, but trust me, they’re worth it. You have a great chance to find Water Filters in them, and players have reported seeing tons of Legendary items, such as Kinetic Converters, in them, and I myself have found many pinks in them.
Security Breaches are scattered across all the maps, but you can find one in the Power Generation Complex on Dam Battlegrounds, which you can visit and loot before gunning for the RnD building.
