Innovation, comfort, quality: our Performance™ Series whole-home humidifiers represent more than a century of experience in making homes more comfortable. A Carrier humidifier enhances indoor comfort by adding moisture to dry air during the heating season. A properly humidified home can promote higher system efficiency while providing relief from many of winter’s discomforts.

  • HUMIDITY MANAGEMENT A Carrier humidifier can “moisturize” dry, heated winter air, making your home feel more comfortable. That’s important because during the heating season, your home can feel drier than the desert.
  • COMFORT Properly humidified air can provide comfort benefits during the heating season beyond feeling warm and cozy. It can help relieve the discomfort of dry nasal passages, itchy skin and static shocks as well.
  • HEALTHY AIR Keeping humidity under wraps can protect against warping or structural damage to wood flooring or furnishings.
  • WHOLE-HOME SOLUTION Our Carrier humidifiers easily tie into your heating and cooling system to provide a convenient, effective whole-home solution. With five distinctly different models, there’s a Carrier humidifier that is just right for your home.
  • EFFICIENCY Keeping wintertime relative humidity in check can help you feel more comfortable without overheating your home. You might even be able to turn the thermostat down a few degrees to save on energy costs.
  • LIMITED WARRANTY To the original owner, our Performance Series whole-home humidifiers are covered by a 10-year parts limited warranty. The limited warranty period is five years if not registered within 90 days of installation except in jurisdictions where warranty benefits cannot be conditioned upon registration.
