Unlike other spray nozzles, our patented, Ruby-orifice nozzle would not can become clogged in hard water situations, necessitating the use of water filter, periodic cleaning of nozzle, or nozzle replacement. Cold Fog ® ruby-orifice nozzles have Lifetime Unconditional Orifice-Wear Warranty.

  • Simpler than bypass types to install – single cut hole for installation, no additional ducting.
  • Uses little electricity.
  • Small, compact unit – fits where other types cannot.
  • Because it does not require bypass ducting it does not undermine the pressure separation (and therefore, blower efficiency) of the return and supply ducts.
  • Does not require use of moisture pads (on-going expense).
  • Highly efficient usage of water. Does not generate waste water and does not require separate connection to a drain.
  • Requires little maintenance. Periodic cleaning of nozzle may be required in hard water environments.
  • Lack of a pan of potentially stagnant water to serve as a breeding ground for mold as with a drum-style humidifier.
