Pleated filter paper has major advantages over flat round filters:
- time savings required to fold round filters into squares to fit the cone of filter funnels in repetitive or multiple analyzes
- reduction of the overall filtration time thanks to the larger filtering surface; the normal slowing down of the filtration speed due to particle loading is delayed
- increase of the total load capacity thanks to the greater filtering surface
- maintenance of the filtration speed due to the reduced contact of the filter paper with the wall of the funnel and, of course, due to the self-standing shape of the filter itself
- pleating does not significantly affect any technical data and the same data as for round filters are valid
