Monadnock's vacuum filter papers are custom designed to meet the specifications of cleaner OEM's or their filter bag producers. Filter media are composed of high strength cellulose or cellulose/ synthetic fiber blends. Air flow is a critical performance characteristic and the cubic feet per minute flow is designed to optimize performance of the finished bags, be they single or multi-ply construction.

Monadnock Non-Wovens LLC, a subsidiary of Monadnock Paper Mills, manufactures melt blown synthethic filtration media for use in combination with cellulose webs to produce high efficiency vacuum bas.

Critical performance characteristics include Porosity / Air Flow (CFM), Dust Retention / Filtration Efficiency, High Wet Strength, Processability and Printability.
