Abstract
A method for manufacturing a plurality of filter assemblies is provided that includes providing first and second housing sheets and positioning a filtration medium therebetween. Heat and pressure are applied to form first, second, and peripheral seals of at least two filter assemblies at the same time. Each second seal is positioned outboard of the associated first seal with a non-seal area therebetween, while each peripheral seal is positioned outboard of the associated second seal. The first seal commingles the housing sheets and the filtration medium, while the peripheral seal and the periphery of the second seal commingle only the housing sheets. The peripheral seal may include a tear seal to enable separation of a plurality of adjacent filter assemblies.
