Air filter: multi-layer filtration, effectively blocking tiny particles

In the face of increasingly severe air quality problems, how to ensure the freshness and cleanliness of indoor air has become the focus of modern families and businesses. As the core component of air purification equipment, the air filter has become an important line of defense to protect our breathing health with its multi-layer filtration and effective blocking of tiny particles.

The working principle of the air filter is based on sophisticated filtration technology. It is usually composed of multiple layers of different filter materials, each of which has a specific filtration task. The outermost layer is often the primary filter layer, which is used to block large particles in the air, such as dust and hair. The main function of this layer is to extend the life of the internal high-efficiency filter layer while reducing the filtration resistance.

Next is the high-efficiency filter layer, which is the core of the air filter. It uses more refined filter materials to capture tiny particles in the air, including bacteria, viruses, pollen, smoke, etc. This layer has extremely high filtration efficiency and can block most of the tiny particles that are harmful to the human body, ensuring that the air entering the room reaches a high degree of cleanliness.

In addition to the primary and high-efficiency filter layers, some advanced air filters are also equipped with activated carbon layers or other special filter materials. The activated carbon layer can absorb harmful gases and odors in the air, such as volatile organic compounds such as formaldehyde and benzene, further improving the air quality. Other special filter materials may filter specific pollutants, such as PM2.5, ozone, etc.

The multi-layer filtration design not only improves the filtration efficiency of the air filter, but also makes it more adaptable and durable. Filter materials at different levels work together to deal with various pollutants in the air to ensure the freshness and cleanliness of indoor air. At the same time, multi-layer filtration also extends the service life of the air filter, reduces the frequency of replacement, and reduces the cost of use.

It is worth mentioning that with the advancement of science and technology, the filtration technology of air filters is also constantly innovating. Some new air filters use nano-level filtration materials or electrostatic dust removal technology, which can more effectively block tiny particles and even achieve the filtration effect of HEPA level (high-efficiency air filter). These new technologies not only improve the filtration efficiency of air filters, but also make them more energy-saving and environmentally friendly, in line with the concept of modern green life.
