A four-page brochure on the PurePak electronic air filtration system is available. According to the manufacturer, the system does not create ozone, lose efficiency as filter media increases, or require large, noisy fans. PurePak uses a patented carbon core filtration media system that absorbs odors and conducts an electrical charge that creates a polarizing field. The air scrubbing combination of electrostatic polarization and activated carbon is 97 percent effective at capturing contaminants down to 0.3 microns. The air filtration system can be added on to the company's SpacePak line of air conditioners.
