Humidifier tank empties unusually fast and room feels overly damp or condensation forms on windows.

Safety first: Unplug before moving the unit if there is risk of water spillage.

• Step 1 – Check humidity setting: Set the target humidity to 40–50% RH. Higher settings often cause condensation in cool climates.
• Step 2 – Use auto mode: If available, use automatic humidity control instead of continuous mode.
• Step 3 – Relocate unit: Move the humidifier away from cold windows and exterior walls where condensation is more likely.
• Step 4 – Verify sensor accuracy: Compare the unit’s humidity reading with a separate hygrometer. If the unit reads much lower than actual, the RH sensor may be faulty and should be replaced.

Proper humidity control protects your home from mold and condensation damage; avoid running the unit continuously at high set points.
