Tank size and runtime decide refill frequency. The Crane holds 1 gallon for up to 24 hours, the Fontaines holds 2 liters for up to 33 hours, and the Lightest Pick holds 2.5 liters with a top-fill tank. A bigger tank with a longer runtime means fewer trips to the tap, so match the tank and the runtime to your refill routine.

All three fill from the top, so compare what else each one adds. The Crane adds a sound machine with 3 white noise options and a color-changing night light. The Fontaines adds a nightlight, a water level indicator and auto shut-off. The Lightest Pick adds a carry handle and a 7-color night-light. Pick the extras you will actually use each night.
Check weight and coverage
Weight decides how easily a humidifier moves, and coverage decides which rooms it fits. The Lightest Pick weighs 1.9 lb, the Fontaines weighs 2.14 lb and the Crane weighs 2.38 lb. The Crane covers rooms rated for up to 500 sq ft by the maker and the Fontaines covers rooms rated for up to 247.5 sq ft by the maker. Match the weight and the coverage to your room.
