When selecting a fan, the purpose — that is, central or intermittent ventilation — should be your foremost decision-making criteria:
- Continuous, central ventilation system, such as the Panasonic 2-Speed WhisperCeiling Exhaust Fan FV-11VQD2, are used to to continuously replace stale air with fresh, clean air in the whole house quietly and energy-efficiently. In the summer, in fact, circulating air can keep your house feeling 4 degrees cooler.
- Intermittent ventilation fans, such as the Panasonic WhisperFit-Lite Exhaust Fan, are used in certain areas like the bathroom, kitchen, or garage to quickly exhaust moisture and chemicals. In fact, if you live in an â€œairtightâ€ home, the Panasonic â€œbathroomâ€ (intermittent) fans are quiet and energy efficient-enough to continuously ventilate your entire home.
