Positioning: Placing the humidifier in a central location away from walls and obstructions allows for better air circulation and moisture distribution. Ideally, it should be elevated on a table or shelf to enhance the spread of humidity throughout the room.
Use a Hygrometer: A hygrometer is a handy tool that measures the humidity level in the air, helping you to adjust the settings on your humidifier accordingly. This ensures that you maintain the desired humidity level without over-humidifying the space.
