摘要： Disclosed are filter media packs having a single layer of a high loft filter media and a single layer of a low loft filter media, the filter media pack characterized by the absence of oil added to the filter media pack, the filter media pack capable of filtering air laden particulates from an air stream at greater than 94% efficiency at air stream flow rates of between about 100 feet per minute and 3000 feet per minute. Also disclosed are filter assemblies formed from the filter media pack, and methods of using the filter assemblies.
