Crane 3-in-1 Compact Humidifier vs Crane Personal Ultrasonic Cool Mist Humidifier

Both are small Crane ultrasonic cool-mist units, so the real split is size and extras. The 3-in-1 adds a seven-color nightlight and an essential oil diffuser and holds more water, which suits a nursery or bedside table. The Personal Travel model is smaller, filter-free and built to pack, with variable speed and a 360° lid, but it has no light or aroma function. Owners of both report quiet mist and simple cleaning; the 3-in-1's extra features are the reason to step up unless portability matters more.

• Choose the Crane 3-in-1 if you want a nursery humidifier that also works as a nightlight and aroma diffuser.
• Choose the Crane Personal Travel if you need a compact, filter-free humidifier to move between rooms or pack for trips.
