Dyson humidifier emits a musty or moldy smell during operation.

Safety first: Unplug the unit and empty all water before cleaning. Avoid inhaling cleaning fumes.

• 1. Empty and rinse: Remove the tank and empty all water from the tank and base. Rinse both with warm water.
• 2. Disinfect tank and base: Fill the tank with a solution of 1 part white vinegar to 3 parts warm water. Swirl and let it sit for 30 minutes. Pour some of this solution into the base reservoir as well. Use a soft brush to scrub accessible surfaces.
• 3. Rinse thoroughly: Rinse the tank and base multiple times with clean water until all vinegar smell is gone.
• 4. Drying: Allow components to air-dry with caps off before reassembly.
• 5. Maintenance routine: Change water daily and perform a full clean at least weekly. If odor persists even after thorough cleaning, internal channels may be contaminated and require professional disassembly and cleaning.
