They should add a little sticker that certifies that the humidifier supports water conservation, but in the sense of energy conservation or momentum conservation.

Some humidifiers use an oscillating diaphragm to mechanically aerosolize the water. No heat, No steam.

Others are just a huge wick and a fan, also known as swamp coolers. Aprilaire whole house humidifiers work this way. Those are quite effective as well, and no heat or steam.

Yeah this is the ultrasonic type. The diaphragm is basically a waterproof speaker fed with a signal in the 3-5 MHz range. I don't get how the fine liquid bubbles don't coalesce. Are they all similarly charge or something?
