METHOD OF CONFORMALLY PROFILED CARBON FILTER FILLING Russian patent published in 2017 - IPC B01J20/20 B01J20/30 B01D24/00 A62B23/02 

FIELD: personal care items.

SUBSTANCE: method of forming a conformal filtering layer comprises a determination of the container inlet inner perimeter to form the filter layer, providing with filling tube with the first size inner perimeter. The filling tube first size is smaller than the inner perimeter of the filter layer, and a storm filling, at least partial, of the filter layer with the filter granules. Filtration granules are passed through the first filling tube for forming a layer in the filter layer. In one invention version the second filling tube with the second size inner perimeter is provided. The filling tube second size is smaller than the inner perimeter of the container inlet inner perimeter, and differs from the tube first size inner perimeter, while the filter granules are passed through the second filling tube for forming the second layer in the filter layer.

EFFECT: efficient production of filter with high performance.
