Researchers create air filter that can kill the coronavirus
Why not use a HEPA filter?  Surely, if it can filter heavy isotopes, coronavirus won’t fit through.  Coronavirus doesn’t last more than a few days without a host, so the HEPA filter will eventually “kill” 100% of the virus as well.<p>Also, ~8-18% of the population (mostly women) is allergic to nickel due to A combination of genetic predisposition prolonged contact with nickel-coated jewelry.  Presumably this filter dumps trace amounts of nickel dust into the air.  What could go wrong?
