<p>PURPOSE:The production of filter showing low pressure loss, comprising coating the opposite faces of a pair of three dimensional mesh elastic sheets with a limited amount of synthetic rubber latex having a specified particles size, dispersing adsorbent such as activated carbon into the space between two sheets, and joining two sheets each other by pressing. CONSTITUTION:The opposite faces of a pair of three dimensional mesh elastic sheets having a gap size of 9-31 per about 25mm wide in a skeleton structure, are coated with synthetic rubber latex having a particle size of 0.03-1.5mu in an amount of 250-500g of resin solids per m<2> of area of sheet, preferably 350-400g/m<2>. After dispersing an adsorbent such as activated carbon into the space between two sheets, two sheets are piled up and joined each other by pressing.</p> |
