Most people have questions about adding essential oils to their air humidifier. Does adding to the incinerator increase the benefits of using it or are there any dangers? How to add essential oil to your air humidifier? It is important to note that it is not recommended to add essential oils to cold mist humidifier. The purpose is to add essential oil to the device water. It should not be added to the ultrasonic cold mist humidifier. Never. The ultrasonic cold air humidifier vibrates the water and directs it to the outlet of the machine. When the water is essential this frequency is not enough to vibrate and the device is damaged. In hot or warm mist humidifier even if they use heat to evaporate water adding essential oils will reduce the useful life of the device. You can only use essential oils in a device that has a separate chamber for essential oil. Because in this type of air humidifiers the compartment of the essential oil is placed in the vapor path of the device and does not need to be added to the water. In general pouring essential oil into the water will reduce the useful life of the device. So it's best not to use essential oil as much as possible. Try to use as much as possible refined water or solvent-free water to fill the machine. If you have no solvent-free water and you have a lot of water you can place it in the water filter. Of course some of the embedded devices are on their own and there is no need to buy it separately. When your water has a lot of salts these salts when evaporated are dispersed as particles in the air.
