Where to Find Humidifiers in ARC Raiders

The Humidifier is a rare Residential-zone loot item in ARC Raiders required for Stage 4/6 – Outfitting of the Expedition Project. You’ll need 5 Humidifiers to complete this step, along with several advanced crafting materials. Because Humidifiers spawn only in Residential Loot Zones, they can be difficult to farm consistently. But there are two highly recommended locations we have found: Buried City (with a guaranteed Humidifier spawn) and Dam Battlegrounds (with multiple Residential buildings to search).

Why You Need Humidifiers

For Outfitting (Stage 4/6) of the Caravan Expedition Project, you must gather:

• 5 × Humidifier
• 5 × Advanced Electrical Components
• 3 × Magnetic Accelerator
• 3 × Leaper Pulse Unit

When you reach Stage 4 of the Caravan Expedition Project, most players quickly realise that Humidifiers are one of the hardest items to find. They may seem like they should be common, but in practice they can be surprisingly difficult to obtain. To make this step easier, we’ve highlighted two of the best locations to farm Humidifiers reliably so you can progress your Caravan without the stress.

Buried City Humidifier Location (Guaranteed Spawn)

Step 1: Load Into Buried City

Enter Buried City using any loadout. This map contains the only guaranteed Humidifier spawn currently known.

Step 2: Head to Red Tower Near Plaza Rosa

Travel to the Red Tower, located just beside the Plaza Rosa zone, south part of the map.

If you are coming from the south, climb on the rooftop and follow the exterior walkway around the tower until you find a hole into the building. Drop down and enter inside.

Step 3: Loot the Two Red Lockers

Once you enter through the hole of the building, you will find:

• Two Red Lockers
• One Security Breach Locker

Go ahead and loot both Red Lockers — one of them always contains a guaranteed Humidifier (unless looted by another Raider).

Since this area counts as a Residential Zone, check the other drawers, cabinets, and small containers nearby, just incase you might get lucky for any more.

Step 4: Extract Quickly via the Metro Station

Once you are down, its time to exit the raid. The Red Tower farming route is incredibly fast because the Metro extraction point is located directly beside the building.

Head down the stairs and extract immediately — then repeat the run if needed.

Important Tip

This location has become widely known due to content creators.
If you join a lobby late, the lockers are often already looted. In that case, switch to Dam Battlegrounds for a more reliable fallback.

Dam Battlegrounds Humidifier Locations (Best Alternative)

Step 1: Load Into Dam Battlegrounds

Enter Dam Battlegrounds using any loadout or free loadout. This map contains several Residential Zones that can spawn Humidifiers.

We not 100% certain but apparently Night Raid, seems to have a higher chance of spawning them from other raiders experience.

Step 2: Head to Pale Apartments & Ruby Residence

Once you load into the session. Travel to the north-west outskirts of the map, where you will find:

• Pale Apartments
• Ruby Residence

These are full Residential buildings, which have the primary loot category where Humidifiers can spawn.

Step 3: Search Kitchens, Cupboards & Room Containers

Inside each apartment building, check every lootable container such as:

• Kitchen cabinets
• Bedroom cupboards
• Storage shelves
• Side-room drawers

These are the highest-chance locations to find Humidifiers.

While not guaranteed like Buried City’s Red Tower, this area has very low player competition and can produce multiple Humidifiers across several clean runs.

Step 4: Extract and Repeat

After fully clearing Pale Apartments or Ruby Residence, head to the nearest extraction point and secure your loot.

Because you need five Humidifiers, you may need several Dam Battlegrounds runs, or you can combine this with Buried City Red Tower attempts for faster results.

Extra Tip: Trading & Multi-Run Strategy

Since Humidifiers are very rare, consider using the Metaforge Marketplace to trade for missing components or sell surplus loot to acquire them indirectly.

Or simply gather them naturally while completing other Expedition steps — they spawn randomly enough that you’ll occasionally pick them up without actively farming.
