Air cleaning filter

Abstract

The invention relates to the technical field of air purification filters, in particular to an air purification filter, which comprises a shell, wherein a PM2.5 particle filtering layer, an organic pollutant purifying layer and an ozone catalytic purification filtering layer are arranged inside the shell, and simultaneously at least one layer among an initial effect filtering layer, an antibacterial filtering layer and an anion generating layer made of anion generating materials is also arranged inside the shell. The novel air purification filter purifies the indoor air and simultaneously can also purify PM2.5 lung impairment particles and ozone exceeding the national sanitary safety standards due to atmospheric haze pollution and near-earth ozone pollution, and has important practical significance of improving the life quality and preventing diseases caused by air pollution.

Description

technical field

[0001] The invention relates to the technical field of air purifiers, in particular to an air purifying filter. Background technique

[0002] In recent years, with the study of compound atmospheric pollution, the seriousness of the hazards of haze pollution and near-earth ozone pollution to human health has emerged. Atmospheric smog is formed by complex reactions of automobile exhaust and industrial pollution under the action of sunlight. The main components are aerosol lung-damaging particles smaller than 2.5 microns, complex organic pollutants, such as acetyl peroxynitrate, aldehydes and other irritating compounds. The ozone in the atmosphere comes from the breakdown of the normal near-earth air ozone cycle chain, the ozone cannot be produced and degraded normally, and the harmful concentration exceeds the limit of the health standard. A large number of research data analyzes have proved that haze and near-ground ozone pollutants are harmful to the human ...
