Here’s the latest you can use right now:
-
Most reliable spot: Red Tower in Buried City. Look in the red lockers on the second floor; these lockers almost always contain humidifiers. The Red Tower is just east of Santa Maria Houses and northeast of Plaza Rosa. This is repeatedly cited as the easiest farming route for humidifiers.[1][2][3]
-
Alternative spots if you’re unlucky at the Red Tower: residential areas around Dam Battlegrounds or Dam West, Plaza Rosa vicinity, and Space Travel Building lockers in Buried City. These locations are commonly mentioned as backup sources in recent guides.[3][4][1]
-
Quick farming tip: some guides describe a fast loop that starts at the Red Tower, then checks nearby residential plots and apartment blocks for higher spawn chances. If you’re short on time, prioritize Buried City routes but don’t ignore nearby residential zones as a secondary option.[5][3]
-
Notes on availability: humidifiers are a common Expedition Project loot item, but they are not guaranteed in every run, so having a couple of backup locations can save you time.[9][3]
If you’d like, I can pull together a concise mapped route you can follow in this session (step-by-step with waypoint references) and estimate how many runs you’d typically need to reach your quota. I can also summarize the pros and cons of each location to help you decide where to search first.
