The invention discloses a filter material and a filter assembly. The filtering material is provided with different functional layers; all the functional layers comprise a physical filtering functionallayer and a chemical filtering functional layer, wherein the physical filtering functional layer and the chemical filtering functional layer are overlapped front and back in the filtering direction;the chemical filtering functional layer comprises a chemical filtering layer for filtering at least one volatile organic compound; the physical filtering functional layer comprises a second physical filtering layer for filtering at least one volatile organic compound; and the filtering material further comprises a connecting layer for connecting two adjacent functional layers. By arranging the connecting layer, the problem that the resistance of the to-be-filtered object is increased due to disturbance of the large gap to the to-be-filtered object can be avoided, and the filtering process is more stable; tests prove that the resistance of the to-be-filtered object can be reduced by at least 30%; and by arranging the connecting layer, a plurality of functional layers can be compounded intoa whole, so that the damage problem caused by shaking and mutual collision of the functional layers is avoided.
