  • Trion humidifiers help provide a healthier, more comfortable indoor climate- because susceptibility to viruses and bacteria is greater when the inside air is too dry, maintaining proper humidity levels can help make indoor air healthier. See chart at bottom of page.
  • Energy cost savings and increased comfort: indoor air will feel warmer at 68°F ( 20°C) when properly humidified than it will at 73°F (23° C) when relative humidity levels are too low. The Herrmidifier 707U humidifier allows the homeowner to lower the thermostat, experiencing substantial savings on monthly energy bills, without sacrificing comfort.
  • Protects fine furniture: because wood tends to shrink, split, and crack in an environment that is too dry, adding the proper amount of moisture to the air helps lessen these problems
  • Fast installation: coming with a self-piercing saddle valve and requiring just a 3 1/2" (89 mm) diameter hole cut into a duct, this unit can be up and running in no time
  • Incredibly easy assembly: just fit the dome snugly on top of the pan, that's it!
  • Flexible operation: 24 V / 120 V / 240 V wall- or duct-mount humidistat is easily adjustable from 20% to 80% relative humidity
