  1. Big humidifiers can be found at stores that sell musical instruments. Many wooden instruments are very sensitive to too low humidity and humidifiers are used to fix the problem. I would guess that the hardware store has cheaper prices for the same stuff if the same product is available in both sources.

  2. 9:27 The ultrasound humidifiers cause exactly the same power usage as the boiling water thingy - the evaporation takes the same amount of energy per 1 g of water no matter how you convert the water from dropplet to gas. In case of ultrasound humidifier the energy is taken from your house heating system. Granted, it might have better COP than 1.0 that electric heater in water can do. If you need to heat your house anyway and you need to use humidifier, the boiling versions are least bad option because it causes least issues with lime stains and avoids mold and algae inside the humidifier.
