For Residential and Light Commercial Applications
The Coronavirus disease, or COVID-19, is a virus that is mostly transmitted through the air in water droplets found in coughs and sneezes by those infected. UVC irradiation has the ability to kill any kind of bacteria or virus. The COVID-19 virus is 0.1 microns in size making it highly susceptible to UV-C (https://www.cdc.gov/coronavirus/).
The amount of UVC necessary to kill virus varies from virus to virus. Here are a few examples measured in Microwatt Seconds per Square Centimeter:
Adeno Virus Type III 3 4,500
Bacteriophage 1,3,4,5,6,9 6,600
Influenza 1,2,3,4,5,7,9 6,600
Infectious Hepatitis 1,5,7,9 8,000
As you can see some are easier to kill than others, but all are killed by UVC.
What we do know is it takes a considerable UV dose to kill germs and virus. The principle of UVC sterilization is related to intensity of the lamps used. The more powerful the lamp the better the kill. The larger/longer the duct the better the kill. The slower the air is moving the better the kill.
The type of light and quantity of lights and intensity and power of each light varies. The placement varies. The brand that is best for you will vary. We provide and install a whole host of UV lights for residential, commercial and hospital-grade applications.
Please note that a UV light will only kill about 80% of airborne viruses per pass. So this does not replace the needs for all the other safety meausres receommend by heath professionals, officials and the federal health authorities. It simply compliments the meausres. By the way, we also provide more robust and powerful solutions for your office. So, if your office or place of work needs something like this (they all should be fitted with these), please have them contact us.
