“ A crisper drawer, sometimes called a humidity drawer, is a bin in your fridge that helps preserve freshness and may prolong the lifespan of your fruits and vegetables by exposing them to different levels of humidity.”
That’s from Whirlpool, a NA manufacturer, the rest say the same. Might be slightly cooler as it’s always on the bottom of the fridge, but the main selling point is higher humidity.
The “crisper” drawer on our fridge (low end LG, very old) is the worst for moisture, I don’t understand why manufacturers recommend putting veggies in such a saturated atmosphere.
