Cool-mist humidifiers and warm-mist humidifiers create water vapor clouds of different temperatures, but cool-mist humidifiers are best if you’re using hard water.

How Do Humidifiers Work? Humidifiers are designed to increase the humidity in your home by pulling water from an internal tank, converting it into moisture, and dispersing it into a room.

A humidifier is a machine that adds moisture to the air. The best way to determine if you need one is to understand a bit about humidity and humidifiers.

Evaporative humidifiers work differently, relying on wick filters doused with water that collect any minerals before the water vapor is distributed via a fan.
