Humidifiers play an essential role in maintaining indoor air quality, particularly in dry environments or during winter months when heating systems can strip moisture from the air. Among the various types of humidifiers available, warm mist humidifiers have become increasingly popular due to their ability to create a soothing, warm atmosphere. They work by boiling water to produce steam, which cools slightly before being released into the air, effectively raising humidity levels.
