2020 Hindsight
We can all agree that 2020 has been the decade of years. If we think back to approximately 12 months ago, some of the top stories in the news included the World Cup-winning US Women, the fire at Notre Dame Cathedral, and Hurricane Dorian (yes those things were only last year!).
Before 2020, we usually thought of masks like those worn by children for Halloween, the ability to purchase disinfectant was an afterthought, and science was usually referred to as a class our kids took in school. So what have we learned this year? What do we have to look forward to?
Among the many lessons, we’ve learned are many ways to improve our safety within our workplace. We at CDA are striving hard to make this happen, and we are leaders in this field. You may have read our previous newsletters where we’ve discussed different technologies. Within this article, we will provide an overview to summarize end-of-the-year documents.
We’ve learned that there are quite a few technologies available to purify the air. Filtration is the most common and typically the most effective method for HVAC systems. Other technologies, including irradiation and thermal sterilization, inactivate biological particles in the air without removing them. HVAC systems can also incorporate ionic purifiers, ozone generators, and other devices for sanitizing air.

There is never a “one size fits all” approach to removing viral and other harmful particles from the air. Alternatives and options need to be considered to provide the right answer in each setting. In addition to mitigating harmful particles, some of the options, such as Bi-Polar, further provide the benefit of reduced energy costs.
The primary options for use in buildings today seem to be, Ultraviolet, Bi-Polar and high-performance filtering. Furthermore, there are benefits to increasing the ventilation of “fresh” air in addition to using any of the previous three options.

And now…the reason you scrolled to the end:
Chewie's Cozy Corner

As we approach the end of the year, Chewie has informed us his holiday wish list consists of: more naps more treats, and for Mom to look the other way when Dad tries to slip him a scrap of bacon!
In addition, he wishes everyone the fullest bowls of holiday cheer. He suggests that in lieu of hugging family and friends, give your 4-legged friends the extra love!
