Dynamic Air Cleaners utilize active–field, non-ionizing polarized-media technology. While Dynamic has pioneered and perfected its application to air cleaning in general HVAC applications, the basic principles have been around for a long time. In fact, the word “electricity” comes from the Greek word for amber elekton when it was observed that dust particles would hop onto amber after it had been rubbed. That seemingly magical force was called electricity. The first electrically-enhanced air filters date back to 1930 and combine elements of both passive and electrostatic filtration. As with most high-efficiency filtration products, polarized media had its roots in industrial applications. Although there have been a number of different configurations since then, all are based on charging or polarizing fibers in a media and particles within the air in order to generate an electric force between the fibers and particles. While the principle has been around for many decades, it has only been in recent years that the technology has been fully understood to maximize effectiveness and to provide consistent, reliable performance.
In 1982, two university professors from Carleton University in Ontario, Canada developed a polarized media design for a residential application that provided a simple means of replacing dirty media. They started Engineering Dynamics, Ltd. (EDL) and began manufacturing 1” and 2” polarized-media air cleaners, room console units and overhead ceiling-mount units, all under the Dynamic brand. All of the polarized-media air cleaners on the market today can be traced back to beginnings at EDL, although subsequent patents and refinements have created discernable differences in the product designs and features.
In 1993, EDL was acquired by Environmental Dynamics Group, one of EDL’s largest distributors. The companies are now known as Dynamic Air Quality Solutions. With headquarters in Princeton, New Jersey the primary manufacturing operation still resides in Carleton Place, Ontario. Although the company’s initial focus was on residential applications, Dynamic has strived to address the clear need for improved air quality and energy savings in commercial and industrial applications. This has resulted in an emphasis on technology enhancements, new product configurations, and a complete, comprehensive line of commercial products that now dominate in some categories. Today, healthcare and energy retrofits are the company’s two largest business segments.
Dynamic has doubled sales every few years, invests heavily in research and product development and holds a variety of patents on the technology.
