Powerful & Reliable Stainless Steel Ultrasonic Fogger for Humidification or Fog Effects

💨 Always Free Shipping on All Products — No Hidden Costs!

The 12XL Mist Maker is our highest-output kit at 9,000ml/hr — built for the biggest jobs. It's designed for the largest greenhouses and grow rooms, commercial mushroom fruiting rooms, warehouses, and industrial humidification, holding humidity in spaces well beyond the reach of smaller units.

For projects larger than about 20×40 ft targeting 95% humidity, you may need more than one unit — many large operations pair a 12XL with a second unit (such as a 9 Disc) for full coverage and redundancy. Coverage depends on ambient humidity, fresh-air exchange, heat/AC, and lighting — see our sizing guide, or contact us and we'll size your space. For standard homes and rooms under ~10×20 ft, the 9 Disc or 12 Disc is the more economical choice.

Perfect for:

• Largest greenhouses & grow rooms (20×20 ft and up)

• Commercial mushroom fruiting rooms (90–99% humidity)

• Warehouses & industrial humidification

• Commercial fogponics & large hydroponic operations

• Whole large homes & commercial spaces

• Large-scale special effects & fog installations

Built from stainless steel—not chrome-plated zinc that corrodes and leaches into your water—this fogger features an LED-free design that prevents algae growth and extends lifespan. The twelve large 20mm ceramic discs produce fine, dense mist with higher output and superior durability compared to smaller 16mm brass discs used by competitors.
