Filters and HVAC Choices to Mitigate COVID discussed in webinar yesterday
This 90-minute webinar covered choices to filter the air in buildings and vehicles using the most cost-effective products and technologies. The benefits include protection from air pollutants as well as viruses. Christine Sun of Waterloo Filtration Institute outlined the potential benefits. Bob Mcilvaine provided evidence that most COVID transmission is through small aerosols. Some of these aerosols are generated when larger droplets are only temporarily captured by inefficient masks and filters.
Bob Burkhead of Blue Heaven Technologies then described the testing rig which could be adapted to test filter efficiency over time and not just measure what is temporarily captured. This rig allows recirculation of up to 1000 cfm and can measure degradation of meltblown media over time, ozone levels when ionizers are utilized, and other contaminants which need to be assessed over time. Barry Kellar, Saru Dawar, and Uwe Haffner of Freudenberg talked about the needs in vehicles where conditions are rapidly changing. The company is addressing the potential for aerosols generated from surfaces as well as directly from people and has an efficient filtration system which includes a surface layer of a proprietary citric acid compound which inactivates the virus. Freudenberg recognizes the role of very fine particles (smaller than 0.3 microns) and is looking at capture rates on activated carbon due to diffusion. There was a brief discussion on the potential to spray citric acid in the vehicle interior similar to the Purdue concept of spraying food dyes into classrooms. Bob Mcilvaine then summarized market aspects such as the much higher efficiency of H13 filters than MERV 16 in capturing small particles and virus. The decision on which product to choose is enhanced by a value system which takes into account lives saved and sickness reduced compared to the economic and life quality costs.

Product innovations will be the key to solving the COVID problem
the webinar yesterday focused on a few of the product innovations which can solve the COVID. But there is a whole arsenal being created which will be instrumental in winning the war. Efficient masks and filters will be available. Innovative air system designs such as fan filter units for meat packing stations instead of partitions will also be part of the solution. There are so many developments that Mcilvaine is publishing daily alerts in order to keep clients informed. Click here for more information
Pandemic is impacting all the air, water, and energy markets
In general, the pandemic is depressing most of the air, water, and energy markets. It will continue to do for the next several years. The impact will be uneven with the U.S. India, Brazil and some other countries being much more affected than China, Japan, Taiwan, and Korea.
the indoor air filter market will be very positively impacted with revenues more than doubling over the next two years. The fabric filter market will be impacted primarily due to reduction in investment by the chemical, wood products, steel and mining industry. The precipitator market will be impacted more by the reduction in coal combustion than COVID.
the IIoT & Remote O&M market will be bolstered by building automation investments to control air quality. the continuing growth in food and pharmaceuticals will benefit liquid microfiltration, centrifuge, and cartridge suppliers. The Mcilvaine market reports are found at MARKETS
