Where to Find a Humidifier is a quest in ARC Raiders about finding a household item needed for the fourth stage of the Expeditions project. Below is a guide on the fastest places to find humidifiers and how to make farming easier.
Where to look for humidifiers

- Humidifiers can appear as individual items or inside containers in residential areas , but the chances of them appearing there are extremely low.
- The most reliable way is to look for them in the red lockers on the second floor of the Red Tower in the Buried City.
- This point almost always gives at least one humidifier per visit, allowing you to quickly collect the required five.
How to get to the Red Tower
- Climb up to the ledge at the subway entrance next to the tower.
- Then go up the stairs to the second floor.
- Directly opposite the stairs is a row of red cabinets – they provide a high chance of spawning humidifiers.
- The location is located near the metro, so you can quickly leave with loot, even if you’re playing with free gear without a safe pocket.
If the lockers are occupied or already looted
Humidifiers may appear in other residential areas as well. Check:
- Village on the Blue Gate
- Ruby Residential Sector at the Dam Battlefield
- Pale apartments there too
These areas are also good for finding valuable trinkets to sell, so running through them is rarely empty.
If you need to quickly complete an Expedition stage, the Red Tower is the best and most reliable source of Humidifiers. Other residential areas are only worth checking if the main route is occupied or already cleared.
