The Best Humidifier for a Baby

The best humidifier for a baby is the same one that’s best for adults—it just needs to be cleaned more often. Beyond that, a humidifier in the baby’s room should run all night without over-humidifying or needing a 4 a.m. tank refill. The model that meets those needs is the same one we picked in our guide to the best humidifier: the Honeywell HCM-350 Germ-Free Cool Mist Humidifier. It doesn’t have the cartoonish cuteness of some other humidifiers marketed for children's rooms (which is arguably not exactly a flaw). More seriously, this model is easier to clean and maintain than nearly every competitor out there, and we can’t overstate how much cleaning and maintenance are required to operate a humidifier in a baby’s room in the healthiest possible way.
