Scientists have designed a "catch and kill" air filter which they say can trap the novel coronavirus and neutralise it instantly, an invention that may reduce the spread of Virus in closed spaces such as schools, hospitals and health care facilities, as well as public transit environments like airplanes.
According to the study, published in the journal Materials Today Physics, the device killed 99.8% of the novel coronavirus, SARS-CoV-2, in a single pass through its filter.
The device, made from commercially available nickel foam heated to 200 degrees Celsius, also killed 99.9% of the spores of the deadly bacterium Bacillus anthracis which causes the anthrax disease.
According to the scientists, since the virus can remain in the air for about three hours, a filter that could remove it quickly was a viable plan, and with businesses reopening across the world, they believe controlling the spread in air-conditioned spaces was urgent.
They noted that the novel coronavirus can’t survive temperatures above 70 degree Celsius, so by making the filter temperature far hotter -- about 200 degree Celsius, the researchers said they were able to kill the virus almost instantly.
I think Log 9 Materials is listening to this.
