Advantages and disadvantages of photocatalyst activated carbon air purification?

Time: 2022-03-31

Advantages of Photocatalyst Activated Carbon Air Purification:


Under the action of light, photocatalyst can oxidize and decompose formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other harmful organic substances, pollutants, odors, bacteria, etc. into harmless CO2 and H2O. The product has efficient and broad-spectrum disinfection performance. Effectively control the cross-infection of bacteria and viruses to control the reproduction of bacteria and purify the air. The product itself does not change and only provides a reaction site. It has the advantages of lasting time, continuous action, safety, non-toxicity, and no secondary pollution. It is an internationally recognized green, environmentally friendly and pollution-free product. The products of Shanghai SFFILTECHphotocatalytic activated carbon air purifier manufacturerhave the following characteristics. Comprehensiveness: photocatalyst activated carbon air purification can effectively degrade formaldehyde, benzene, toluene, xylene, ammonia, TVOC and other pollutants, and has efficient and broad-spectrum disinfection performance, which can kill and inhibit the survival of bacteria, fungi and viruses.


Sustainability: During the reaction process, the photocatalyst itself will not change and be lost, and it can continuously decompose pollutants under the irradiation of light, which has the advantages of lasting and continuous action.

Safety: Non-toxic, harmless, safe and reliable for the human body; the final reaction products are carbon dioxide and water, without secondary pollution.

Efficiency: Photocatalysts can decompose pollutants diffused in the air by using light sources such as ultraviolet light, sunlight, and fluorescent lamps.

Bactericidal Function: It has the effect of killing and inhibiting bacteria such as Escherichia coli and Staphylococcus aureus.

Deodorizing Function: It has the effect of removing cigarette odor, toilet odor, garbage odor, animal odor, etc.

Self-Cleaning Function: It can play a self-cleaning role on the surface of indoor and outdoor objects.

Purification Function: It has the function of degrading organic harmful substances in sewage.

Disadvantages of photocatalyst activated carbon air purification: It is necessary to keep the light in the room as much as possible to provide a good working condition for the photocatalyst. At the same time, the photocatalyst, like other passive air purification products, needs the harmful substances in the air to contact its surface to react. Some ventilation is good.

It is a photocatalyst product with good effect under fluorescent lamp. The photocatalyst has been tested by the [National Environmental Protection Product Quality Supervision and Inspection Center] authoritatively. Under 24h fluorescent lamp, the removal rate of formaldehyde is 81%, the removal rate of benzene is 82%, and the removal rate of TVOC is 78%. Under the detection conditions, the purification effect is at the leading level.
