Please make sure the cotton core soaked in water 3-5 minutes until full absorbed before your first time use. 2. Mineral water, cold boiled water and clean tap water are the best, pure water and distilled water are not recommended. And do not add essential oils into the containers. Trouble Shooting: If the humidifier not used for a long time,the cotton core will be dry,which will lead to no fog.It needs to be soaked again. It is recommended to use short cotton core, long cotton core fogs smaller in the case of low water level. Replace the cotton core if it absorbs too many impurities. Using too much of essential oils will lead to blockage of the atomized plate.Just use cotton swabs and a little vinegar to gently wipe the atomized plate in this case.
