Killer Air Filter - In a Good Way
With the war against COVID-19 still raging, researchers at the University of Houston have unveiled a new weapon: an air filter that can trap and kill the SARS-CoV-2 virus, which is responsible for COVID-19.
According to their study, which was published in the journal Materials Today Physics, the new, high-tech filter is made from nickel foam that is heated to 392° F -- hot enough to kills 99.8% of virus particles in just a single pass through the filter.
It's thought the filter, which was created in partnership with Houston-based medical real estate development firm Medistar, could be employed in elevators, offices and other confined spaces where air recirculates and therefore could spread airborne diseases.
"This filter could be useful in airports and in airplanes...schools and cruise ships to stop the spread of COVID-19," says lead researcher and University of Houston professor of physics Zhifeng Ren.
What's more, the high-tech filter can wipe out anthrax spores.
The team that built the filter is first looking to deploy it in high-risk environments like hospitals and airports, before trying to scale it down to make a desktop version.
