    I built a variation from your instructions. These instructions were inspiration to make one half the size, with a 6-disc ultrasonic emitter in a 5-gallon pail. You just can’t buy anything else like this in the marketplace. It’s crazy that you have to buy the components and piece it together if you want a whole-home ultrasonic humidifier. Adding an automatic float valve with an ice maker line, this is a completely automatic system. I also attached some PVC pipes and elbows to direct and distribute the dog. Thanks for sharing!

    These are good for many uses, but for me I would rather use the electricity for lights.
