Buying advice: humidifiers

  • 1Ultrasonic cool mist models are quiet and efficient. Evaporative models use a wick and fan and cannot over-humidify. Warm mist models boil water, which reduces germs but uses more power and is a burn risk around children.
  • 2Match output to the room. A small unit in a large living area will run constantly without raising humidity much.
  • 3Look for a wide-mouth — top-fill tank and few hidden crevices. Clean weekly and change water daily.
  • 4Ultrasonic humidifiers can spread minerals from hard tap water as white dust. Distilled water or a demineralization cartridge prevents it.
  • 5A built-in humidistat stops the unit at your target level and saves you from over-humidifying.
