Panasonic Eco Solutions’ newest ventilation fan, the WhisperFresh Select, is designed to help builders meet the ventilation requirements for tightly built homes. The fan integrates with both central HVAC and ductless systems, and it may be used as a standalone whole-home solution or paired with Panasonic’s multispeed central fans. The unit’s ECM motor with SmartFlow Technology is designed to ensure optimal output, and the Pick-A-Flow Air Selector allows contractors to manually adjust the unit’s airflow settings between 50 cfm and 150 cfm. The vent fan costs $860. panasonic.com
