‘Catch and Kill’: Scientists develop air-filter in US claiming it can trap and kill coronavirus
New Delhi | Jagran Lifestyle Desk: Researchers in the America’s University of Houston have developed a ‘catch and kill’ air filter which scientists claim can trap the Coronavirus, and can reportedly neutralise its existence.
This may decrease the risk of COVID-19 spread in the closed spaces, such as schools, colleges, hospitals, indoor sports complexes, alongside public transport means, metro, buses and railways as well. The scientists say that since the virus can remain in the air for close to three hours, a filter that could remove it quickly was a viable plan
According to a study published in Materials Today Physics journal, the device developed by University of Houston researchers can kill 99.8 per cent of the novel coronavirus, just within a single pass through its filter.
The device is comprised of already widely available Nickel-made foam, which is heated to 200 degrees Celsius, far more than 70 degrees Celsius at which Coronaviruses may survive. And thus, the researchers said, they were able to “instantly” neutralise the virus in the surroundings.
“Schools, transit systems, hospitals, aeroplanes, office buildings, other health care facilities and public settings would be first in line to receive the devices,” Garrett K. Peel of Medistar, a Houston-based medical real estate development firm which has partnered with the University of Houston for developing the device was quoted as saying by the news agency PTI.
Furthermore, the high-temperature at which the device works does not mean that it will interfere with the cooling or air conditioning in place since the air filter is electrically heated and not heated from any external source.
That’s how the amount of heat escaping from the device is minimised. And since the whole point here is to ‘trap’ the virus, there is the least possibility for anything to escape out of the filter.
“This novel biodefense indoor air protection technology offers the first-in-line prevention against environmentally mediated transmission of airborne SARS-CoV-2, and will be on the forefront of technologies available to combat the current pandemic and any future airborne biothreats in indoor environments,” said Faisal Cheema, co-author of the study was quoted as saying by PTI.
