New Technology Turns Ceiling Fans into Air Purifiers.

Ceiling fans are popular, but the air they circulate is often loaded with dust, pollen, molds, smoke, animal odors and more. Now, Heartland Technologies LLC of Derby, Kansas, has introduced the Purifan System, which turns any ceiling fan into an efficient air purifier.

The Purifan System, a self-contained, circular unit that replaces the paddles of a standard ceiling fan, uses a three-stage filtration system: a prefilter, a charcoal filter, and a high-efficiency-particulate-air (HEPA) filter to help remove unwanted and unhealthy contaminants in the home, office, or workplace. The Purifan uses natural high and low air pressure to draw up unclean air and recirculate the fresh air at a rate of 2,000 cubic feet per minute. That means it completely recirculates and refreshes the air in an average 20-foot-by-20-foot room every 90 seconds.

While many stand-alone air purifiers can be effective, they are notorious energy guzzlers and move only a fraction of the air moved by a typical ceiling fan. The Purifan uses no more energy than a ceiling fan, takes up no floor space, and is a considerably more quiet alternative. It sells for $269.95 and can be installed in minutes.
