Cimatec's products are 1- and 2-inch electronic air cleaners that fit into standard filter racks found on most residential-type air-handling systems.

The filters use Electronic Bipolarization Technology (EBT), Roblin explained, which allows them to trap submicron-size particles with minimal pressure drop.
