High-efficiency filters and laminar air flow systems needed in the battle against COVID-19
At the time of this writing, 800,000 people around the world have died from COVID-19. There have been 22 million reported infections. There is growing evidence that small aerosols are a major transmission source. Social distancing, inefficient masks, and MERV 8 filters are not a viable defense when dealing with a sub-micron enemy. Without some …
More efficient masks are the best weapons against COVID
The filtration industry needs to take the lead in resolving the COVID problem. Transmission does not come from contaminated food, mosquitoes or fleas. Very little transmission has been traced to surface contact. The new evidence is that small aerosols provide a major route for COVID transmission. These aerosols create viral clouds, which are not deterred …
Is filtration more effective than social distancing in preventing virus spread?
At the time of this writing, the CDC predicts 135,000 deaths in the U.S. from COVID-19. McIlvaine has calculated the cost in terms of life quality reduction for those sickened, as well as those dying, plus healthcare costs at $58 million per death. The result is a $7.8 trillion cost, not including lost economic activity. …
As coronavirus surges, filtration questions arise
There is extraordinary confusion about the basic issues that will shape the market for face masks and filters relative to the coronavirus pandemic. This applies to fundamental questions, such as does a medical mask provide protection for the wearer? Will the virus travel through the air and ductwork? How long will the virus remain viable? …
Applications determine air filter market share & influence total cost of ownership
Air filtration media is used in treating ambient air as well as process-generated particulate. Filtration media companies, such as Lydall and Ahlstrom, provide media for both applications. There is some media common to both applications, but the process applications require cleaning of the media and can involve high temperatures, acid gases and other contaminants not …
