Another alternative is to use essential oils or other natural substances like eucalyptus or tea tree oil. These can be added directly to the water reservoir or used in a diffuser that attaches to your humidifier.

It's recommended to use pure, non-iodized salt, such as kosher or sea salt. Table salt or salt with additives may contain minerals or chemicals that could be harmful to the humidifier or the air quality.
It depends on the manufacturer's instructions. Some humidifiers are designed to be used with certain types of water or additives only, and using salt may damage the device or reduce its effectiveness.
The amount of salt to use varies depending on the size of the humidifier and the desired level of humidity. It's recommended to start with a small amount, such as 1 teaspoon per gallon of water, and adjust as needed.
