The principal mode by which people are infected with SARS-CoV-2 (the virus that causes COVID-19) is through exposure to respiratory droplets carrying infectious virus. In the early days of the pandemic we were told about the staying power of the virus on substances, such as stainless steel, cardboard, plastics, etc. The survival rates were from four hours up three to four days. Back then my wife and I would put on nitrile gloves to collect our mail. The concern of course, was coming into contact with the virus and then touching our mouth, nose or eyes. Now we are learning from the experts that that is not the main way that the virus spreads. Surface contamination still needs to be respected, but the spread of infection through exposure to virus-containing respiratory droplets is considered the primary explanation.
Respiratory droplets and pathogenic viruses can travel over large distances and remain airborne for long periods of time. HVAC air current also provide momentum for the surge.https://www.cdc.gov/coronavirus/2019-ncov/more/scientific-brief-sars-cov-2.html
An asymptomatic diner was able to infect numerous diners in a restaurant, with some seated more than 20 feet away. Complex patterns of airflow can keep viruses aloft, a dramatic example that six feet of distance is not sufficient for safety. The CDC still affirms that six feet provides ample safety and the wearing of face masks mandatory. - Indoor activities, especially in enclosed spaces, whether at the office or a food establishment, are of great concern to health experts.
With 10 or less games played in the 2021 NHL season, numerous games have been cancelled and forced to reschedule, because of the aggressive transmission of the virus. The NHL has made changes to the in-arena COVID-19 protocols. The first step is to remove the glass or plastic sheets, behind the player's bench, to allow for better airflow. The teams have also been asked to install portable air cleaners behind the benches, to improve the quality of air and help reduce airborne transmissions.
The recognition and the gravity of airborne transmission has been well documented for reduction of these pathogens. Providing HEPA filtration in the HVAC systems along with UV lighting is vital. Additionally, portable units can be introduced to your businesses, to maintain a an active layer of protection and confidence against airborne viruses to ensure people are safe indoors and in shared spaces such as a doctor’s office, school/daycare facility, restaurant, or manufacturing facility.
We are not referencing air units that you would use at home. Those units are practical for persons with allergies and other breathing impairment's. In order to provide the security necessary for your business you will require an instrument, qualified for use in medical applications as well as institutional. - The UVairo air sanitizer is such a match.
The UVairo is considered a best choice with a particle reduction of 96% in just 5 minutes of operation. That's with 12,602,000 virus Particles Killed/m3 in air: (5 minutes). A 99.993% reduction are achieved in just 30 minutes. No other company in the United States is showing these success rates in such a short amount of time! The science behind its effectiveness is the special wavelength of ultraviolet (UV) light known as the germicidal range (254nm) that can deactivate viruses and bacteria. Air is drawn in,
filtered, and passed through a high-intensity UV-C light chamber, removing harmful particulates. - The effectiveness is dependent on how long the air is exposed to UV-C, the wavelength the light is at, and how intense the light is. UVairo air sanitizer uses the preferred wavelength for killing microorganisms and also use an intense bulb that allows deactivation the microorganisms, in a short time.
There are three UVairo devices available with airflow ranging from 450 CFM, 600CFM and 1600CFM.
