(2) The medicament method adopts high-efficiency oxidant such as chlorine dioxide to purify and kill the air, the medicament loss needs to be maintained, and the oxidant has destructive influence on the indoor environment and is not good for the health of human bodies.

(3) The plasma method utilizes high-pressure ionized air to generate low-temperature plasma, generates oxidation reduction effect, and treats indoor air, but the effect is generated on corresponding indoor area only when certain power is reached in use, however, the power rise can lead to ozone rise, and the ozone is harmful to human bodies, influences human health and is not environment-friendly.

(4) The ultraviolet irradiation method is to kill bacteria and viruses in the air by using an ultraviolet lamp, but ultraviolet rays with the wavelength of 254nm are ineffective in chemical pollution treatment, and if the ultraviolet rays with the wavelength of 184nm are adopted, a large amount of ozone can be generated, so that the human health is damaged.

(5) The photocatalytic method generates high-energy electron hole pairs by photocatalysis to generate an oxidation-reduction effect and purify air, but in actual use, when the concentration of pollutants is high, the pollutants which cannot be treated in time can cover the surface of the catalyst, light rays are blocked to irradiate the photocatalyst, the catalytic activity can be slowly reduced, and the effective effect is difficult to play.

Therefore, the traditional indoor air purifier is difficult to realize the functions of chemical pollution elimination, sterilization and disinfection and environmental protection at the same time, and the indoor air cannot meet the requirement of human living health.
