Where to Find Humidifiers in ARC Raiders
Linear run based on the Dec 9, 2025 reference: the two red lockers in Red Tower (Buried City) give a near-guaranteed Humidifier with a metro extract beside it; if contested, pivot to the northwest apartments in Dam Battlegrounds for low-traffic container sweeps. Each loop takes about 3–6 minutes.

Why you need Humidifiers
Caravan Expedition Stage 4 (Outfitting) needs 5 Humidifiers. They only drop from Residential loot, so random searching is slow. Use the two high-signal spots: Red Tower lockers for a near-guaranteed pull, and Dam apartments for low-contest, container-dense backup runs.
Route 1: Buried City Red Tower (fastest)
Head to the Red Tower beside Plaza Rosa. Core idea: sprint the tower, drop through the wall gap, open the two red lockers, and extract at the metro next door—reset the lobby within three minutes.

Steps
- 1) Spawn and sprint to Plaza Rosa. Ignore side loot; stamina matters.
- 2) Climb the outer scaffolding, enter via the wall gap. Circle the roof to find the opening.
- 3) Open both red lockers. One usually holds a Humidifier; check nearby drawers for extra residential loot.
- 4) Drop to metro and extract immediately. If empty, reset the lobby to maximize attempts.



Route 2: Dam Battlegrounds apartments (low contest)
When Red Tower is stripped, switch to the northwest residential block in Dam. Pale Apartments and Ruby Residence have dense residential containers with low competition—often enough to finish the remaining Humidifiers in 1–2 raids.

Steps
- 1) Pick night or off-peak lobbies. Less PvP, higher container completion.
- 2) Clear Pale Apartments first. Prioritize kitchens, wardrobes, side cabinets, and shelves.
- 3) Rotate to Ruby Residence. Hit kitchens and small storage rooms; avoid lingering in hallways.
- 4) Extract nearby and queue again. Residential loot is light—speed beats hoarding.


3–6 minute repeatable script
- 1) Queue Buried City → sprint Red Tower → two red lockers → metro extract.
- 2) If empty, queue Dam → Pale Apartments → Ruby Residence → extract.
- 3) Alternate maps until 5x Humidifiers are secured.
- 4) Grab Advanced Electrical Components, Magnetic Accelerators, and Leaper Pulse Units en route to cut future trips.
Loadout and pacing tips
- Go light; Humidifiers weigh little—speed and stamina trump capacity.
- Lockbreakers help with nearby secure lockers, but don’t detour from red lockers/residential drawers.
- Night or off-peak lobbies increase Red Tower success; in primetime, go straight to Dam to save time.
- Duo split: one camps Red Tower, one clears apartments to finish the 5-piece requirement faster.
After you have 5
- Combine with Advanced Electrical Components and Magnetic Accelerators to finish Outfitting.
- Recycle spare residential junk per the loot page to keep stash space free.
- Plan ahead for Stage 5: Dam apartments can also feed medical/lab items while you’re there.
