Running a humidifier with a window open is largely counterproductive and inefficient, as the added moisture escapes while dry air enters. While not entirely "pointless" if the device is close to you (e.g., on a nightstand), it wastes energy and makes it difficult to raise the overall room humidity.

Can I use a humidifier with the window open?

After purchasing a humidifier, the question often arises as to whether you can continue to sleep with the window open or tilted. The answer is no, because that would be counterproductive. The humidifier constantly supplies moisture to the room air.

Can opening a window help humidify a room?

Opening windows promote air circulation in your home which can lower the humidity levels. So, when using a humidifier, it's best to close the windows to help the unit work properly. However, if you notice that the humidity has exceeded the ideal levels of 50%, you can open the windows to prevent mold growth.

Where should you not place a humidifier?

You should not place a humidifier on carpet, wood furniture, near electronics/wiring, in corners, directly by vents/windows, or within reach of children/pets to avoid moisture damage, electrical hazards, uneven humidity, or burns. Instead, use a flat, elevated surface like a table or nightstand in a central spot for better air circulation. 

Does running the AC help with mold?

Yes, air conditioning (AC) helps prevent mold by removing moisture (dehumidifying) and improving airflow, as mold thrives in damp, stagnant air, but it doesn't kill existing mold and can even create mold if the system itself gets dirty or malfunctions. Running the AC in humid conditions and keeping filters clean are key, but proper system sizing and maintenance are crucial to avoid making mold problems worse.
