Is UV Disinfection Safe?

During the COVID-19 pandemic, hospitals, airports, hotels, schools, and endless other large facilities have been scrambling to find ways to efficiently sanitize their premises. 

Fortunately for them, UV disinfectant has been proven trustworthy as an established technology for sterilization since 1845.

This unique means of sanitation can be used to disinfect surfaces, water, and air. 

But is it actually safe?

Let’s take a look.

Understanding the risk

UV disinfection uses ultraviolet (UV) light at a wavelength of between 100-280 nanometers in order to kill or deactivate harmful microorganisms like bacteria and viruses, thus sanitizing the designated areas. This process is called irradiation. 

UV disinfection is most commonly used to clean surfaces like keys, cell phones, and entire hospital rooms. It’s a great choice for those who want to avoid chemicals and harsh cleaning products. 

However, sterilizing large areas or objects may be time-consuming, so keep that in mind. UV light can be harmful to your skin and eyes when you are in direct contact with it. For this reason, rooms should be completely empty while surfaces are being disinfected. Once the cleaning has been completed and the UV light has been turned off, the room will be safe to reenter. 

Some researchers have found that certain carcinogenic chemicals may be formed when using UV light to disinfect water, although they occur at such small levels that they do not pose any real risk to humans. That being said, there should be no concern when using UV water disinfection like the LUMARS, LUX, and SULAOS systems for hotel or commercial laundry.

This method does not require any chemicals or filters to work, which will save you money in the long run. It’s also environmentally-friendly, allowing you to spend less on your energy bill each month.

UV light is equally as safe when disinfecting the air. Technology like Spiro-Max kills 99.9% of bacteria and viruses that cycle through your HVAC system without producing any harmful by-products that will then be breathed in by your occupants. This is an especially useful tool when it comes to killing airborne viruses like COVID-19.

UV disinfection is safe to use and can save you money in the long run. When using UV disinfectant, the only real concern you should have is making sure that your lights are regularly replaced and direct human contact with the UV rays is avoided.
