Surveys show that modern people spend 90% of their time living and working indoors on average, and the degree of indoor pollution in modern cities is several times higher than outdoors. Therefore, the relationship between indoor air quality and human health is closer and more important.

An air purifier refers to a product that can filter, absorb, decompose or transform various pollutants in the air, and effectively improve the cleanliness of indoor air. Its main function is to remove particulate matter in the air, such as pm2.5, pm10, pollen , fiber, hair, etc. At the same time, it can also absorb and purify chemical pollutants introduced by decoration materials and furniture, such as formaldehyde, benzene, ammonia, TVOCs, etc., as well as biomass pollutants, such as bacteria and viruses. According to the characteristics of persistence and uncertainty in the release of air pollutants in relatively closed spaces, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

At present, in the air purifiers with activated carbon adsorption and purification function on the market, the activated carbon bed of the activated carbon filter is made of granular activated carbon filled plastic or paper honeycomb panels. The problem is that the activated carbon is not filled uniformly. Generally, only about 50% of the air-passing area is filled with activated carbon to increase the air flow through the net, so that only the airflow that flows through the activated carbon can be adsorbed and purified, and the airflow that flows through the unfilled part The airflow is directly discharged without any adsorption and purification, which greatly reduces the purification efficiency, and even becomes a decoration without any effect.
