I got one because in Arizona, the water quality's terrible, but the air is bone-dry to the point it turns your skin to sandpaper. The hard water means that vaporizing humidifiers fill the air with white dust that coats everything, because they vaporize the minerals. Evaporative humidifiers don't; the minerals all end up in the filter. And, while an evaporative humidifier has no trouble going through a full tank of water overnight on the lowest settings in AZ, it phsyically can't oversaturate the air like a sauna in the way that a vaporizing humidifier does.
The air in the north east just doesn't get dry enough (maybe in winter, but then you don't have the AC fighting your humidifier), and if boiling a pot of water is what the author's looking for, an evaporative humidifier just doesn't do that.
