Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
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.

I don't know about this particular solution, but in general yes, you can filter away and/or destroy viruses. Read a paper where they had very good success with, if I recall correctly, HEPA filters + UV light.

We have an air filtration unit in our bedroom, primarily because our neighbor has a wood stove that causes tremendous particulate pollution throughout the neighborhood. It works very well, at least as far as can be detected by smell.

My concern is about changing the filters without shaking all the bad stuff loose.

DNA collected from air could revolutionize the monitoring of biodiversity
Two independent teams of researchers -- one based in Denmark and the other in the United Kingdom and Canada -- set out to collect several air samples from two European zoos: Hamerton Zoo Park in the U.K. and Copenhagen Zoo in Denmark. Their findings, published Thursday in the journal Current Biology, showed the presence of a wide range of animal species both within and outside the two zoos.
"We were even able to collect eDNA [environmental DNA] from animals that were hundreds of meters away from where we were testing without a significant drop in the concentration, and even from outside sealed buildings.
UK virus [RNA] hunting labs seek to bolster global variant network
The laboratory is one example of how British scientists have industrialized the process of genomic sequencing during the pandemic, cutting the time and cost needed to generate a unique genetic fingerprint for each coronavirus case analyzed.
Britain made sequencing a priority early in the pandemic after Cambridge University Professor Sharon Peacock identified the key role it could play in combating the virus and won government funding for a national network of scientists, laboratories and testing centers known as the COVID-19 Genomics UK Consortium.
That has helped slash the cost of analyzing each genome by 50% while reducing the turnaround time from sample to sequence to five days from three weeks, according to Wellcome Sanger.

Increasing sequencing capacity is like building a pipeline, according to Dr. Eric Topol, chair of innovative medicine at Scripps Research in San Diego, California. In addition to buying expensive sequencing machines, countries need supplies of chemical reagents, trained staff to carry out the work and interpret the sequences, and systems to ensure that data is shared quickly and transparently.
