| — In-game description |
The Gas Mask Filter (a.k.a "Filter") is a consumable utility item used by Gas Masks to protect players from the deadly clouds of Gas Grenades which progressively consumes the filter.
Description
The Gas Mask Filter is a utility item consumed by equipped Gas Masks to reload their filter.
When an empty Gas Mask is equipped, a filter from the inventory is automatically consumed to refill its 100 filter points. When inside a Green Ash cloud, the mask loses 7 points every second. Sitting it out in a cloud for the full duration makes the equipped Gas Mask loses 77 points. When hit by Green Ash and out of points, the mask automatically tries to recharge by consuming the first filter in the player's inventory.
Gas Mask Filters do not stack in the player's inventory unless they are wearing a Tank Uniform (stacks of 2 per slot).
Production
| Structure | Input(s) | Output | Time |
|---|---|---|---|
Factory  (Utility) | 100 x Basic Materials  | 1 crate  of 20 x Gas Mask Filter  | 00:00:50 |
Storage
It does not stack in structure or vehicle inventories (1 per slot).It can only be stored in the stockpile of Bases (32k max).
Crates of Gas Mask Filter can be directly submitted to any item stockpile that accepts that item to transfer their content.The crates can also be stored in the crate stockpiles of Storage Depots (1000 public, 100 per Reserve Stockpile), Seaports (1000 public, 100 per Reserve Stockpile), Shipping Containers (60), or Storage Ships (1000).
It can be transported by almost any vehicle with inventory slots. However it is much more efficient to transport it in bulk amounts as crates, either delivering them to a Base's stockpile with a Truck or to a crate stockpile with shipping vehicles carrying Shipping Containers.
Tactics
- Generally speaking, infantry should not be equipping them, unless they are using equipment that requires them to be stationary. (i.e. mounted weapons)
- Vehicle crewmembers should always carry a gas mask and multiple filters as those are high priority targets for gas attacks.
