New metrics for filter selection and ‘true cost’ determination
There are new measurement tools to select filters, as well as new holistic concepts which obsolesce traditional individual selection methods. There are also new measurement needs. Measurement Tools: The COVID-19 pandemic has created a major controversy over life quantity vs life quality. It is likely that filtration selection will be permanently impacted by the efforts …
Millions of lives can be saved with an efficient mask program
Three billion people are wearing masks every day to reduce the spread of the SARS-Cov-2 virus. No mitigation option compares to providing them with tight fitting and efficient protection. When both transmitter and recipient wear masks with a fitted filtration efficiency (FFE) of 90%, the net result is 99% virus capture (i.e., 99% solution). It …
A sea change in the filter industry is underway
The true cost of one filter as opposed to another has been traditionally limited to considerations of energy cost vs performance. Health has been a factor in filter decisions, but not dominant. In this pandemic era the concept of true cost includes health factors measured in $ billions and even $ trillions and is unlike …
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 …
