Buying Guide: Nursery Safety
Keep these points in mind before you buy.
Safety features that matter
Look for auto shut-off when the tank is empty, a child lock if a toddler can reach it, and a stable spot out of reach with the cord tucked away.
Choose cool mist for nurseries
EPA says to keep steam vaporizers out of children’s reach because steam and boiling water can cause burns; cool-mist and evaporative models avoid hot water near a crib.
Skip scents and oils
Some models have aroma pads or trays; we suggest leaving them empty around babies unless your pediatrician approves.
Safety Tips
Keep little hands safe:
- Place it out of reach.
- Tuck and secure the cord.
- Use the child lock.
- Never use steam near a crib.
