We recommend clean the water tank and transducer once every month. Rinse the filter with clean water once every 3 month. Once every six month, immerse the filter with white vinegar for 10 minutes and rinse under clean water. If not going to use for long time, please drain out all the water, let it air dry and store in a safe place.
When cleaning the humidifier, please unplug power cord, and drain water out before cleaning.
