Check the prevailing Dew Point & Humidity in your Area. The highter the Dew Point or Humidity the more ventilation is needed when using Evaporative Cooling. In more humid areas this may lead to considering the K2 and the Air Intake Housing Kit.

To find the
Dew Point or Humidity in your area click on your favorite weather site and put in your City and State for present & past readings.

Check the Continental USA Map or World Map to see if your area is typically Humid or Dry.
