▎ 摘　　要

NOVELTY - Antibacterial and antiviral filtering device crossed by contaminated air, comprises at least one column structure of many contiguous filter modules (1) delimited by a lateral surface at the inlet and a lateral surface at the outlet, where the antibacterial and antiviral filtering device comprises at least one biological pre-filter (2) located in a seat (3), the seat located upstream of the lateral inlet surface in a drop and collection area of a quantity of fine particles of biological contaminants and/or aerosol residues released from the contaminated air. USE - The device is useful for: antibacterial and antiviral filtering crossed by contaminated air (claimed) by adopting the 3D printing technology; and separating using semipermeable membranes; tubular membrane modules, with a porous block having membrane-coated passages, separation processes using semipermeable membranes, e.g. dialysis, osmosis, ultrafiltration, reverse osmosis, hyperfiltration, nanofiltration. ADVANTAGE - The device: defines and controls a compromise between the filtration capacity and the fluid dynamic energy necessary to move the fluid mass charged with contaminant particles; blocks and eliminates a high percentage of viruses and bacteria that deposit on the filter surface; utilizes UV lamp that allows to increase the bacterial and viral reduction of the filtration system; utilizes ultra-fine HEPA filtration allows increasing the filtration efficiency by reducing the presence of aerosols in the air flow, allowing to block the residual ultrafine particles of particulate matter; and is suitable for being made with recyclable material, for example, plastic derived from maize, beet. DESCRIPTION OF DRAWING(S) - The figure illustrates essential elements of the antibacterial and antiviral filtering device. 1Contiguous filter modules 2Biological pre-filter 3Seat 6Supporting means 7Sealing means
