Final answer:
Yes, bubbling can occur with wick humidifiers. Regular cleaning and using distilled or filtered water can help prevent it.
Step-by-step explanation:
Yes, bubbling can occur with wick humidifiers.
Wick humidifiers work by pulling water from a reservoir up through a wick and then evaporating the water into the surrounding air. Sometimes, mineral deposits or impurities in the water can build up on the wick, causing the water to bubble or spit out of the humidifier instead of evaporating.
To prevent bubbling, it's important to regularly clean the wick and use distilled or filtered water in the humidifier to minimize mineral build-up.
