Filter Integrity Testing

Filter Integrity Testing


Filter integrity testing is a technique that evaluates the effectiveness of a filter to perform its task. This test measures the bubble point (BP) – the pressure required to break the surface tension of the liquid inside the filter and allow the air to pass through to the other side). The BP is specified by the filter manufacturer, and depends on a number of factors including pore size and liquid type.
