Abstract
Various high performance, high efficiency, long service interval air filter media that are cost effective and easy to manufacture are provided. The filter media of the present invention can have at least two layers comprising blends of binder and non-binder fibers that are thermally bonded to one another and set to caliper in a high velocity forced draft oven. The layers can also be subsequently resin saturated, dried, and optionally cured. The resulting media can be characterized as having a gradient in properties such as fiber composition, fiber diameter, solidity, basis weight, and saturant content.
