The invention discloses an air purifying preparation by plants and a preparation method thereof. 15 percent to 25 percent of a deodorant extracted from plants, 15 percent to 25 percent of an off-flavor removing agent extracted from plants, 2 percent to 5 percent of fungicides extracted from plants, 0.2 percent to 1 percent of a dispersed emulsifier and water are added into a closed vacuum mixer blender for 10 to 20 minutes under the conditions that the vacuum degree at room temperature ranges from 1000 Pa to 1500 Pa and the rotation speed is under 40 to 70 r / min; and then the mixture is mixed for 10 minutes under the condition the rotation speed is under 500 to 80 r / min before closed subpackage. The invention adopts natural plants as raw materials, which contains a plurality of composite microorganisms and composite enzymes. The air purifying preparation of the invention overcomes the defects of an air purifying preparation formulated by traditional chemical synthesis. Besides, the air purifying preparation of the invention has the functions of proactively combining pollutants in the air, removing the off-flavor in the air, decomposing germs in the air, swiftly decomposing harmful gas such as formaldehyde, benzene, ammonia, smoke and odor, and efficiently removing germs and mucedine, thus cleaning the air and avoiding causing secondary pollution to the environment. Besides, the air purifying preparation of the invention is non-toxic and harmless to human body, and is convenient for using.
