Why are tiny worms in my cool mist humidifier?

Tiny worms in a cool mist humidifier may be a sign of stagnant water or high humidity levels, creating a breeding ground for organisms like nematodes or other tiny worms. It is important to clean and disinfect the humidifier regularly to prevent the growth of these organisms. Using distilled water and ensuring proper ventilation can also help reduce the risk of infestations in your humidifier.
