My local pharmacy sells air purifiers which claim to kill 99.9% of all viruses using patented plasma technology to "continuously pull contaminated indoor air across internal short-exposure plasma coils, deactivating airborne microorganisms and viruses at the DNA level".

It is claimed they literally pull viruses apart at a molecular level destroying their infectivity.

This groundbreaking device uses a non-selective, rapid killing, patented plasma technology, which offers a unique, safe and scientifically proven solution to killing airborne viruses 24/7.

They have been independently tested in over 30 laboratories against MS2 Bacteriophage, a commonly used surrogate for SARS-CoV (Coronavirus), and were shown to reduce the virus by 99.99%.

Anyone know the science behind this? Is it credible? If so it seems to me such relatively inexpensive and portable devices should be installed in the air-conditioning systems of planes, cars, schools and workplaces.
