Contractors can have the seals factory-imprinted with their name, logo, website address or other details. 

Grand Rapids, Mich.-based Hart & Cooley Inc. offers its Smart Filter Seal with factory-stamped logos, websites, phone number and other information.

Company details can now be emblazoned on the filter seals' 4 inch by 2.75 inch area, officials said.

The printing allows the "calling card of their choosing to display on every job," officials added.
