The invention relates to a natural bamboo fiber filter material and a manufacturing method thereof, the natural bamboo fiber filter material comprises a first chemical fiber layer, a natural bamboo fiber and 4080 mixed layer, a PM filter paper layer, an activated carbon layer and a second chemical fiber layer which are sequentially arranged from top to bottom, and the adjacent layers are compounded together through a hot melt adhesive layer. The manufacturing method of the natural bamboo fiber filter material comprises the following steps: step 1, uniformly mixing granular activated carbon with hot melt powder to obtain a mixture; 2, uniformly spreading the mixture on one side of the second chemical fiber layer, and covering the mixture and one side of the second chemical fiber layer withone side of the PM filter paper layer; 3, heating the mixture through a laser head to allow the hot melt powder to be melted into the hot melt adhesive layer so as to allow the granular activated carbon to be bonded to one si
