Today, let's talk about the topic of general concern about air purification: can air filters resist viruses?

The answer is yes! With the help of air filters, it is indeed possible to achieve reliable protection against viral aerosols.

SAF air filter

The European Federation of Heating, Ventilation and Air Conditioning Associations (REHVA) is a HVAC association that aims to develop and promote energy-saving, safety and health technologies for building machinery services. In the constantly updated COVID-19 guidance manual, REHVA focuses on the reopening and safe use of buildings, and the recommendations on filter upgrading are also listed.

Droplet transmission is a major way of virus transmission between people. When people talk, cough or sneeze, the virus spreads in the air through droplets less than 5um. Due to limited air volume, infectious particles are more likely to accumulate indoors than outdoors. If several people stay in one indoor space, the risk of infection will increase.

In order to minimize the risk of indoor infection, air filtration systems play an important role. The high-performance filter can effectively separate particles of this size range by almost 100%, thus reducing the indoor pathogen concentration. The SAF customized filter scheme can ensure the ideal indoor air quality and minimize the pollution risk through multi-level combination of air filters of different levels.

For public buildings with high hygiene requirements such as food factories, hospitals and shopping malls, the effective compliance of air handling units (HVAC) is undoubtedly the key to protecting human health and ensuring safe production.
