The device killed 99.8 per cent of the novel coronavirus, SARS-CoV-2, in a single pass through its filter according to the report.

The device is made from commercially available nickel foam heated to 200 degrees Celsius, also killed 99.9 per cent of the spores of the deadly bacterium Bacillus anthracis which causes the anthrax disease.

This filter could be useful in airports and in airplanes, in office buildings, schools, and cruise ships to stop the spread of COVID-19.

Its ability to help control the spread of the virus could be very useful for society.

The researchers said they are also developing a desk-top model for the device which is capable of purifying the air in an office worker’s immediate surroundings.
