Benjamin Sturtevant invented the first exhaust fan in 1860, to draw out airborne dust for his woodshop workers. Since then, exhaust fans have been used in homes to remove cooking odors in kitchens and to dry heavy moisture in bathrooms. More recently, whole-house fans were added in today's air-tight energy-efficient homes, where stale air lingered both day and night.

But, as time marches on, so does fan technology and due to ?exhaustive? research (pardon the pun!), indoor air quality is better than ever! Good examples are the new Whisper Aire whole house dual-drive fan that moves 2200 cubic feet of air per minute, with remote control ease, cooling more efficiently than traditional air conditioning. Other new ventilation options and upgrades include new attic fans with roof-mounted solar panels that power on and off thermostatically, without using a drop of household electricity. Today, state-of-the-art home ventilation is easy— and it's come a long, long way from Benjamin Sturtevant's woodshop, so check it out!
