FIELD: filtration.
SUBSTANCE: invention is intended for air and liquid filtration. Technology described in the present document relates, in general, to corrugated filter assemblies, wherein corrugations formed in filter packing pass from the first surface for a filter assembly flow to the second surface for a filer assembly flow, wherein one surface for the flow is an inlet surface, and the other surface for the flow is an outlet surface. Options of filters are described, in which the distance of the first corrugation length between the first surface for the flow and the second surface for the flow differs from the distance of the second corrugation length between the first surface for the flow and the second surface for the flow for more than 2 mm. In some embodiments, at least one of the first surface for the flow and the second surface for the flow is not flat, although, in other embodiments, both the first surface for the flow and the second surface for the flow are flat and non-parallel.
EFFECT: increase in the purification quality.
