All filters cleaned by PPSL are fully tested and the results compared with the "as new" technical specification published by the filter manufacturer. Weight Checking is undertaken as standard:All filters are weighed after cleaning. This enables us to compare the weight of the cleaned filter with the base weight of the new filter. Over time, weight loss can be tracked, and can be a useful factor when determining the continued integrity of the filter.
