UV Disinfection: How It Addresses COVID and Other Health Safety Concerns

The COVID pandemic has everyone on high alert when it comes to cleanliness and disinfection. Hospitals, businesses, and homes take extra steps to ensure surfaces are free of the virus. But what about the air we breathe?

Not many people knew about air and surface disinfection before COVID came along. But now, it’s become a hot topic. And one of the most popular ways of disinfection is UV light.

What Is UV Disinfection?

UV disinfection uses ultraviolet light to kill microorganisms. The UV spectrum can be divided into UVA, UVB, and UVC. UVC is the most harmful to human health, but it’s also the most effective at killing viruses and bacteria. That’s why it’s the type of UV light used in UV disinfection.

How Does UV Disinfection Work?

UV disinfection works by damaging the DNA or RNA of microorganisms. This damage prevents them from replicating, which effectively kills them.

While UV light can kill a variety of bacteria and viruses, it’s important to remember that it doesn’t work instantly. The time it takes to disinfect a space depends on the intensity of the UV light and the amount of time the light is in contact with the microorganisms.

For example, in a hospital setting, a UVDI 360 room sanitizer would need to run for about 5 minutes to disinfect a patient’s room completely.

Is UV Disinfection Effective Against COVID-19?

There are still many things to discover about COVID-19, but what we do know is that it’s a respiratory virus that primarily spreads through droplets from coughing or sneezing.

Studies have shown that UV disinfection can be effective against similar viruses, such as influenza. While more research is necessary to confirm its efficacy against COVID-19 specifically, UV disinfection is a promising option for helping to reduce the spread of the virus.

Are There Any Risks Associated With UV Disinfection?

UV light can be harmful to human skin and eyes, so people must not be in the room during a UV disinfection process.

There are also potential risks to the environment if UV-C light is not used properly. For example, if UV-C light reflects off surfaces, it can cause ozone depletion. Ozone depletion can increase UV radiation exposure, harming both people and the environment.

How Can Industries Use UV Disinfection in Many Industries?

UV disinfection can be used in various industries to help reduce the spread of bacteria and viruses.

Hospitals are one industry that can benefit from UV disinfection. Hospital private rooms can also be disinfected with UV light after patients have been discharged. This can help reduce the risk of hospital-acquired infections, which is a severe concern for both patients and staff.

Food processing facilities can also use UV disinfection to clean surfaces and equipment. This can help lessen the risk of foodborne illnesses, a major concern in the food industry.

Additionally, groceries can use UV disinfection products, such as a disinfection robot, to clean their stores. This can help create a safer environment for both employees and customers.


UV disinfection is a promising technology that can help reduce the spread of bacteria and viruses, including COVID-19. While more research is necessary to confirm its efficacy against the virus specifically, UV disinfection is a safe and effective way to disinfect surfaces and equipment.

Additionally, it can be used in various industries, such as hospitals and food processing facilities, to help create a safer atmosphere for both employees and customers.
