Dry indoor air is more than just uncomfortable—it can affect your health, your sleep, your skin, and even your home’s woodwork and flooring. The Healthy Climate® HC18 is a high-capacity, fan-powered whole-home humidifier that works with your HVAC system to deliver consistent, balanced moisture across every room—no matter the weather outside.
With up to 18 gallons of moisture per day, the HC18 is built for larger homes or households that need a stronger, more consistent humidification solution than portable or bypass units can provide
Unlike bypass humidifiers that rely on the furnace blower, the HC18 has its own integrated fan, allowing it to operate independently of your heating system. That means it works even when the heat isn’t running—keeping humidity levels steady throughout the day and night.
With the ability to provide up to 18 gallons of moisture daily, this unit is ideal for larger homes or families with heightened humidity needs. Dry air doesn’t stand a chance.
Maintains indoor relative humidity between 30% and 60%, the optimal range for human comfort according to national health guidelines. Helps ease dry skin, sore throats, static electricity, and allergy symptoms.
The HC18 runs quietly and efficiently, with simple annual maintenance. Just replace the water panel once per year to keep performance optimal.
The HC18 does not produce ozone, unlike some other indoor air quality systems—making it a safer, healthier option for your family and your home.
