Filter media, filters, and methods for making the same

A filter media consisting of:

• a single layer of 50% or greater of a cellulosic pulp fiber, by weight of the filter media, a bonding material, and 3% or greater of a flame-resistant treatment composition, by weight of the filter media, the flame-resistant treatment composition consisting of citric acid, sodium hypophosphite, and combinations thereof;
• wherein the filter media has a MERV (ed. 2017) rating of 7 or greater,
• wherein the filter media has an initial pressure drop from 0.02 inH2O to 0.45 inH2O at an air flow rate of 110 ft/min, a thickness of 800 μm to 3200 μm, a permeability of 200 cubic ft/min (CFM) to 1000 CFM at 0.5 inH2O, and a density of 0.03 g/cm3 to 0.10 g/cm3,
• wherein the filter media has a dust holding capacity of 30 g/sq.ft. to 50 g/sq.ft. measured at an air flow rate of 110 ft/min and a final pressure drop of 1.0 inH2O, and
• whereby, when the filter media is converted to a filter, the filter meets the flammability requirements defined by UL 900 (8th ed. 2015).
