Cotton swab is an important accessory for filtering impurities in the humidifier. It is a consumable. When the spray volume of the humidifier decreases or does not spray, it needs to be replaced with a new cotton swab
The cotton swab replacement cycle is approximately 15-30 days, and if you add essential oil to the water, this time will be even shorter
I strongly recommend purchasing some cotton swabs as spare parts, as this will prolong the lifespan of the machine!
