There are several types of humidifiers. Evaporative humidifiers blow air through a soaked filter, spraying water droplets into the air. Impeller humidifiers have strong internal fans, which generate a powerful air stream of cool air. Ultrasonic humidifiers are similar to impeller models, but generate moist air with vibrations instead of fans. Central humidifiers connect to central climate conditioning systems. This type of humidifier treats all rooms connected to the central system.Steam vaporizers are popular due to their affordability and portability. These electrical humidifiers generate steam, cool it and release it into the air. Steam humidifiers are small, light and intended for single-room use.
It is important not to over-humidify the air. Excessive humidity encourages mold growth and may exacerbate respiratory health problems, according to Healthline. The ideal humidity is between 30 and 50 percent. Some humidifiers have an integrated hygrometer, a device that measures humidity. Inexpensive hygrometers are also sold separately.
Humidifiers require proper care and cleaning. The tank needs cleaning every three days, according to the Mayo Clinic. Changing the filters frequently also discourages bacterial growth and foul odors.
