Another issue that is frequently wondered by people is whether diffusers and humidifiers are the same. Although they look the same, the purpose of working on both devices is different. Diffusers can work with essential oils to change the atmosphere of the areas where they are used. Diffusers are suitable for use in problems such as throat dryness and clogging. But you cannot add humidifiers to essential oil. They only work to remove the dryness of the areas and restore the correct moisture level. It would help if you preferred humidifiers, not diffusers, to give the moisture that plants need.
