Multi-layer purification, deep cleaning - explore the purification art of air filters

In modern life, air quality has become the focus of our attention. With the acceleration of urbanization and the improvement of industrialization, the types and quantities of pollutants in the air are increasing, posing a huge threat to people's health. Against this background, air filters, as a highly efficient air purification device, have gradually entered our daily lives. Today, let's explore in depth how air filters can achieve deep cleaning through multi-layer purification to protect our respiratory health.

1. The secret of multi-layer purification technology

The core of the air filter lies in its multi-layer purification technology. This technology scientifically combines a variety of different filter materials to form a solid line of defense, intercepting pollutants in the air layer by layer. Generally speaking, the filter layers of the air filter include the primary filter layer, the medium filter layer and the high-efficiency filter layer.

The primary filter layer mainly intercepts large particles in the air, such as dust, hair, etc. This layer of filter material is relatively rough, but the filtration efficiency is extremely high, and it can quickly reduce the concentration of particles in the air.

The medium filter layer further refines the filtration and intercepts tiny particles in the air. This layer of filter material usually adopts a finer fiber structure, which can effectively remove harmful microorganisms such as bacteria and viruses in the air.

The high-efficiency filter layer, also known as the HEPA filter layer, is the core part of the air filter. It is made of polymer materials such as ultra-fine glass fiber or polypropylene, with extremely high filtration efficiency and extremely low resistance. The HEPA filter layer can intercept particles with a diameter of less than 0.3 microns in the air, and the filtration efficiency is as high as 99.97% or more. This layer of filter is the key to ensuring the deep cleaning effect of the air filter.

2. The practical effect of deep cleaning
Through the use of multi-layer purification technology, the air filter achieves deep cleaning of pollutants in the air. In practical applications, the air filter can significantly remove harmful substances such as PM2.5, formaldehyde, benzene, etc. in the air, improve indoor air quality, and protect people's respiratory health.

Especially during the epidemic, the deep cleaning function of the air filter has played an important role. It can effectively remove viruses and bacteria in the air, reduce the risk of epidemic transmission, and provide people with a safer living environment.

3. Maintenance and care of air filters
Although air filters have powerful purification functions, they also require regular maintenance and care. Generally speaking, the life of an air filter is between a few months and a year, depending on the use environment and air quality. When the air filter reaches the end of its service life, its filtration efficiency will drop significantly, and may even cause secondary pollution. Therefore, we need to replace the air filter regularly to ensure that it is always in the best working condition.

In addition, we also need to clean and disinfect the air filter regularly to remove dirt and microorganisms attached to the filter material. This will not only extend the service life of the air filter, but also improve its purification efficiency, providing a more solid guarantee for our healthy breathing.
