I grabbed this one at Target when my LO was sick (it's blue though not grey) and it works great. I like the handle for picking it up to refill the water.
Just know that if you go with cool mist, you have to clean it every single day. They get gross quickly and you don't want to circulate all of that junk into the air - causes more problems than you're solving. I don't use it unless I absolutely have to. I prefer the warm mist and as long as LO isn't free to room the room at night, the safety concerns aren't really there.
I use a warm mist one for colds. It even has a place to put some minty inhalent in there to help break up the mucus. Works wonders for my two kids. I hated the cool mist ones, I felt they didnt really do anything for cold symptoms
