The present invention relates to a filter (1103) configured for use in a hood (1101), comprising: a first flat filter element (1301) adapted to face towards an air inlet (1201) of the hood (1101), a plurality of second filter elements (1302, 1303, 1304, 1305) arranged along the perimeter of the first filter element (1301) to form a side wall extending externally to the air inlet (1202), and a third non-filtering closing element (1306) connected to the side wall to form a box-like structure (1103). The present invention also relates to a filter (2103a, 2103b) configured for use in a hood (2101), comprising: a first flat circular filter element (2301) adapted to face towards an air inlet of said hood (2101), one or more second flat filter elements (2302, 2303, 2304), having the shape of sectors of a circle, arranged along the perimeter of said first filter element (2301) to form a side wall, said side wall being adapted to extend externally to said air inlet, and a third non-filtering closing element (2306) connected to said side wall to form a box-like structure (2103). The present invention further relates to a range hood comprising: a central filter (3103) comprising: a first flat filter element (3301) located within said hood, a plurality of second flat filter elements (3302, 3303, 3304, 3305) arranged along the perimeter of said first flat filter element (3301) to form a side wall, said side wall being adapted to extend partly external and partly internal to said hood, and a third non-filtering closing element (3306) connected to said side wall, external to the hood, to form a box-like structure; one or more side filters (3501, 3502), each comprising a first filtering surface (3504) and a second non-filtering surface (3505), said first and second surfaces facing towards the outer bottom part of the hood, and having oppositely oriented inclinations, said first filtering surface (3504) facing towards the outside of the hood, and said second non-filtering surface (3505) facing towards the inside of the hood and towards said central filter. |
