Before you go

Farming steps

  1. Make or obtain Fabric and gather a supply of Coal and Iron Plates.
  2. Set up a Manufacturer and choose the Gas Filter recipe.
  3. Feed 2 Fabric, 4 Coal, and 2 Iron Plates into the machine for each batch.
  4. Run the eight-second cycle to produce one Gas Filter.
  5. Carry Filters in inventory with a Gas Mask before entering toxic gas areas.

Repeat, collect and use

Make enough Filters for the next excursion and replenish whichever input limits production first.

Common mistakes

  • Assuming the Gas Mask provides filtration without Gas Filters in inventory.
  • Searching for Gas Filters on the map instead of manufacturing them.
  • Forgetting that Fabric is a separate crafted input.

When to stop or switch

Stop when you have the Filter reserve you want or Fabric, Coal, or Iron Plates become limiting.
