YORK® Steam Humidifier.

Humidity When You Need It

The YORK® Affinity™ Series Steam Humidifier delivers optimal humidity levels – up to 23.3 gallons per day (GPD) – even when your HVAC system is not engaged. It also reduces the conditions that can lead to mold, bacteria and virus growth. This option is ideal for applications when evaporative units are less practical, such as with systems located in attics, crawl spaces or closets, or in areas with milder winter climates or homes with a non-forced air heating source.

The Value of Whole-Home Humidifiers

Insufficient humidity in your home can make you feel colder, leading to a higher heating bill. In addition, a humidity imbalance can create a breeding ground for bacteria and viruses, which can have an impact on your health. YORK® whole-home humidifiers help, with simple operation that creates a more comfortable, healthier environment.
