Questions, answered
Is warm mist safe for babies?
No. Pediatric guidance favors cool-mist humidifiers for children's rooms because warm steam vaporizers can cause burns if tipped or touched.
What humidity is best for a nursery?
Aim for 40 to 50 percent. Below 30 percent irritates tiny nasal passages; above 60 percent invites mold. A humidistat takes the guesswork out.
How often should I clean a nursery humidifier?
Daily rinse, weekly deep clean with vinegar. Babies breathe the output all night, so a moldy tank is worse than no humidifier at all.
