A team of engineers from the University of Cambridge has developed a carbon-based air purifier. Tests have shown that the new system removes viruses from premises with an efficiency of 99.9%. A detailed description of the air filter was published in the journal Carbon.
When creating the device, scientists used carbon nanotubes, known for their sorbing properties. Also, the new filtration system was equipped with polyester linings, which not only does not wear out, but also tolerates high temperatures. Its resistance to heat plays a particularly important role, since the device contains filters made of electrically conductive membranes that can heat up to 80 ° C in a matter of seconds and thereby decontaminate.
After the experiments, the scientists found out that the new filtration system effectively cleans the air from various viruses, including the beta-coronavirus. This type of coronavirus is carried by animals and is similar in structure to COVID-19. The device also successfully fights against adenoviruses. They affect the human respiratory system, causing pneumonia or tracheobronchitis.
The creators of the air purification system see the potential for rapid mass production in the development. Scientists have verified the filtration efficiency and suction power that put their device on a par with high-efficiency air filters (HEPA). According to engineers, the new system can be used in ambulances, hospitals, and public places. Scientists also point out that the air purifier can work not only separately, but also together with heating or ventilation systems.
