We have made the decision to discontinue to offer the active humidity feature.
This includes the built-in humidity feature on the self-contained units, split systems, and the stand alone ACH550.
We have found that industry standard built in humidification systems require the use of a water filtration system to remove minerals which can deposit inside of the unit. When installed properly and maintained regularly, the filtration system will prevent scale build up. Without the appropriate type of equipment, scale build up can cause corrosion which will lead to unscheduled and inconvenient maintenance on the cooling unit.
