A closet has no supply vent, no return, and a door that stays shut. Add stored cotton and cardboard and you have an ideal small climate for mildew.
The tell
The smell hits you when you open the door and fades within a minute. That is accumulation in dead air, not a whole-house problem.
Cheap fixes worth trying first
Leave the door cracked, get boxes off the floor, remove cardboard, and add a small dehumidifier or a vented louver door.
When it is more than air
If the shelving, drywall or stored clothing smells on its own after airing out, the materials are holding it and need treatment.
The short version
- ✓No airflow is the root cause
- ✓Cardboard is a magnet for musty odor
- ✓Material smell after airing out means treatment
