Can UV-C Lighting Clean the Air in Your Common Areas?

While the region navigates the new normal as a result of the coronavirus, companies are looking for unique ways to protect employees in the workplace with UV-C lighting. Obviously, the use of masks, disinfecting spray, and hand washing stations have increased. Additionally, many companies have seen the benefit of using microbial lighting as an additional layer of security for common spaces. Currently, there are three types of lighting used to “clean” spaces, UV-C, Far UV and antimicrobial lighting.

How does it work?

UV-C light (250-280nm) lies just beyond the visible spectrum and is a form of electromagnetic radiation. It is known to effectively eliminate mold, bacterial, viral, and other harmful contaminants by breaking down microorganisms in the air. These microbes can no longer replicate and thus no longer survive, nullifying the virus itself. Medical centers have been using this technology for years to purify surgical rooms prior to procedures and it has been medically proven to effectively eliminate the coronavirus. It is important to note that UV-C lighting is dangerous to humans and animals and should not be run while spaces are occupied.

Far UV (201-222nm) is a newer technology which also breaks down mold, bacterial and viral organisms, similar to UV-C. Studies show that low doses of Far UV-C have no effect on humans or animals making it safe to run while spaces are occupied, but can be effective in eliminating viruses in the air and on surfaces, including the coronavirus.

Antimicrobial lighting is on the visual light scale (405nm) and is known to break down bacteria on surfaces only. This lighting has a violet tint and is safe to run in occupied spaces. It is most effective at eliminating antibiotic-resistant superbugs like MRSA and E-Coli, but it does not protect against viruses.

Where can it be used?

Common areas, including beak rooms, conference rooms, classrooms, and waiting rooms are ideal candidates for UV-C lighting. Depending on the application, lights can be used overnight, or while spaces are occupied to reduce the spread of viruses. UV-C lighting options are often considered when the use of heavy chemical cleaners is not ideal or when an area cannot be manually cleaned on an increased cadence.

Buyer beware

There are many different features and brands coming to market. Be sure you purchase a UV-C light option that covers safety certifications and has been tested and assured for compliance in the US.
