Our History in Brief:

1981 – Air Ion Devices, Inc. is founded by Al Barsimanto and begins doing business as AspenAir. Al’s primary objective is to master the technology that will enable cigarette smoke to be effectively removed from indoor air, while providing “balanced” air that is found in nature.

1984 through 1996 – AspenAir sells nearly a million Indoor Air Purifiers, primarily via direct to consumer marketing.

1997 – The company begins work developing a high-efficiency; electronic, whole house air cleaning system, leveraging their breakthrough proprietary technology. Primary focus is to create high-performance units which can be installed either at the furnace or in the return air filter grille. The latest patent for our revolutionary technology was approved in 2006.

2006 – With Mike Gunion as CEO and Joe Castner as COO, (AspenAir) closes its first round of equity financing investment. Primary investment comes from the green building industry.
