Even the most advanced filters are unable to effectively fight bacteria and viruses. A new solution by engineers from the University of Cambridge is able to solve this problem: it copes with the task with an efficiency of up to 99.9%.
The device is based on carbon nanotubes and allows you to clean the air, removing dangerous pathogens much more efficiently than most commercial counterparts. The filter is equipped with polyester liners, which has extended its service life and allows it to perform its tasks at high temperatures. This plays a key role in the operation of the device, since it contains electrically conductive membranes that are heated to 80 degrees for disinfection.
During the experiments, it was found out that the filtration system cleans the air even from beta-coronavirus. It is carried by animals and is similar to the coronavirus known to mankind. It has also been shown to be effective in killing adenoviruses that affect the human respiratory system, causing pneumonia or tracheobronchitis.
The developers hope for the commercial demand for the filter in the market. The device will be especially relevant in ambulances, hospitals and other places where a large number of people gather. The possibility of combined use of the filter together with anti-dust, heating and other systems has been studied.
