The cotton swab plays a crucial role in filtering impurities within the humidifier and is considered a consumable component. When you notice a reduction or absence of spray output, replacing the cotton swab with a new one is necessary. Typically, the replacement cycle ranges from 15 to 30 days, and using essential oils in the water can shorten this interval. To maintain optimal performance and extend the device’s lifespan, we strongly advise keeping spare cotton swabs on hand.
