Clear the air on Covid

Dr. Alondra Nelson, head of the White House Office of Science and Technology Policy and Deputy Assistant to the President, discusses Covid-19 transmission in a recent White House post.

“The most common way COVID-19 is transmitted from one person to another is through tiny airborne particles of the virus hanging in indoor air for minutes or hours after an infected person has been there. While there are various strategies for avoiding breathing that air – from remote work to masking – we can and should talk more about how to make indoor environments safer by filtering or cleaning air…

Dr. Nelson also discusses the benefits of ultraviolet germicidal irradiation (UVGI).

“By inactivating (“killing”) airborne virus through methods like ultraviolet germicidal irradiation systems, we can add another layer of protection in indoor spaces. The latest technology in these UV lights is particularly useful in crowded areas with poor airflow, in healthcare settings with vulnerable populations (such as hospitals or nursing homes), or in areas like restaurants where people aren’t wearing masks because they’re eating and drinking. For instance, one study demonstrated that when used with proper ventilation, UVGI is about 80% effective against the spread of airborne tuberculosis, equivalent to replacing the air in an indoor room up to 24 times in an hour. However, there are some challenges to doing this widely, and more research and innovation is needed to develop UVGI systems that are more affordable, standardized, and consume less energy.”

The Bluezone PK-220 is an affordable and low energy stand alone air cleaner that uses ultraviolet germicidal irradiation to kill airborne viruses and improve the indoor air quality. The PK-220 can be easily installed on the floor, mounted to the wall or installed into 2’x4′ drop-ceiling tiles. Demonstrate your commitment to staff safety with Bluezone.
