- 4
Auto shut-off: Essential to prevent burning out the motor when the tank runs dry.
- 5
Cleaning: Clean weekly to prevent mold and bacteria buildup. Top-fill designs are easier to clean.
- 6
Placement: Keep at least 12 inches from electronics. Place on a waterproof mat or tray.
Frequently Asked Questions
Q:Can a humidifier damage my computer or electronics?
Cool mist humidifiers are safe if kept 12+ inches from electronics. Avoid pointing the mist directly at screens or keyboards. Warm mist produces less ambient moisture and is safer for nearby devices.
Q:What humidity level is ideal for a home office?
40-60% relative humidity. Below 30% causes dry skin and static. Above 60% promotes mold growth. A $10 hygrometer helps you monitor levels.
