Abstract
An apparatus and method for measuring the filtration efficiency of a moving air-permeable web. The apparatus includes a sampling head with an upstream head and a downstream head disposed on opposite sides of the moving web and spaced apart to define a path for web travel. Particle laden air from the upstream head passes through the moving web and is collected in the downstream head where a sampling probe is disposed to collect filtered air for efficiency measurements. The method can be practice on-line in the media manufacturing process to continuously monitor the filtration characteristics and if necessary change the process condition to maintain the filtration characteristics within design parameters.
