Discovery and Early Years
Dynamic Air Cleaners use a
technology called non-ionizing “polarized-media” and it’s
actually been around for a long time. The first electrically
enhanced air filters date back to 1930 and combine elements of
both passive and electronic filtration. As with most
high-efficiency filtration products, polarized media had 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 filter and particles in 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 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 electronic air
cleaners, room console units and overhead ceiling-mount units.
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.
The original EDL was acquired in
1993 by Environmental Dynamics Group, now known as Dynamic Air
Quality Solutions, the manufacturer of Dynamic Air Cleaners.
Initially the focus was primarily residential, but there was a
clear need for improved air quality in commercial and industrial
applications. This resulted in a focus on technology
enhancements, new configurations, and a complete line of
commercial products that now dominate in some categories, such
as casinos.
