The Media Performance Upgrade Kit features advanced filtering technology for Models 2200/2400 and SpaceGard media air cleaners. According to the manufacturer, the kit is intended to retain media replacement business and increase revenue by providing a product that will eliminate retail competition. The kit is designed to improve efficiencies nearly two times by going from a MERV 10 to a MERV 13 filter and reduce service time by eliminating pleat spacers. It includes two galvanized steel rails and four supports, MERV 13 media, and a door spacer to seal the air cleaner door. The kit installs in minutes, and no tools are required, according to the company.
