Ultrasonic Mist Maker Kits — What's Inside & How It Works

Curious what's actually inside an ultrasonic mist maker? Here's the full breakdown of the fogger itself — the part that turns water into cool, dry fog. Click any labeled part (float, stainless transducer, ceramic discs, or power supply) to find its replacement, and hover for a quick description of what it does.

This diagram shows the mist maker unit on its own. To see how it fits into a complete humidifier with a fan and humidistat, visit the interactive Build Your Own DIY Humidifier diagram, or read the Mist Maker FAQ for full specs and setup.

Every part shown here is included in our ultrasonic mist maker kits — each kit ships complete with the transducer, float, a free spare set of ceramic discs, and the power supply. Need a single replacement part? Browse DIY humidifier accessories & replacement parts.
