A supply air terminal unit ( 10 ) has a body ( 11 ) with side walls, top and bottom walls and an opening cover, which is opened to allow access for service work inside the structure. A wall structure ( 12 ) formed by needle-fin tubes ( 100 ) is fitted around a central fine filter ( 13 ), whereby the needle-fin tubes ( 100 ) are placed on top of each other in order to form a filter wall ( 12 ). A needle-fin tube ( 120 ) has needle-like fins whereby in its tube a heat carrier is made to flow in order to transfer heat into the air made to flow through the structure or in the opposite direction. The fine filter ( 13 ) covers an air outlet port (A<SUB>2</SUB>) located in the bottom ( 11 a<SUB>5</SUB>) of the supply air terminal unit.
