Is UV Germicidal Light Safe to use in Nursing Homes?

UV light is a naturally occurring phenomenon. In fact, 10% of the sun’s rays contain UV light, which is a form of electromagnetic radiation.

Science has proven that UV light can be used to prevent the spread of microorganisms and pathogens.

The sun produces several different types of light, which include ultraviolet, visible, and infrared wavelengths. UV light includes wavelengths that are between x-ray and visible light. The nuances that occur within the UV spectrum separate these wavelengths into three sub-bands. This includes UV-A, UV-B, and UV-C wavelengths.

Wavelengths, which are measured in nanometers (nm), make all the difference when it comes to germicide. UV-A light, which includes wavelengths between 315nm and 400nm, are considered the ones nearest to visible light. UV-B light, which ranges between 280nm and 215nm, are considered “middle” wavelengths. UV-C light, which spans between 200nm and 280nm, are those farthest from visible light. They are also the wavelengths considered to have germicidal properties.

So to answer the question, “Is UV Germicidal Light Safe to use in Nursing Homes?” When used properly, germicidal light is extremely safe and effective. With AeroCure 200 and GermZone 100, the UV-C used is completely contained within the unit, so there is no exposure to skin or materials.

What are the Advantages of UV-C Germicidal Light?

The benefits of this long-established germicidal method are well known. In addition to being safe when used properly, some of the benefits of germicidal light also include:


  • Non-Toxic: Germicidal UV light is completely non-toxic. Unlike harsh chemicals that can leave behind residue, as well as germs and other particles – germicidal light can reach into every cranny and crevice. Furthermore, for those who suffer from breathing conditions, harsh chemicals may aggravate symptoms. This is not so with germicidal light.
  • Effective: To date, almost all viruses or bacteria that have been exposed to germicidal UV light have been unable to survive its effects. That means that germicidal light is 99.9% effective. Additionally, all known viruses and bacteria have yet to develop a tolerance towards UV-C germicidal light, meaning there is no chance of these microorganisms surviving exposure. The technology used in our units has been independently laboratory tested to deactivate SARS-CoV-2.

How Does UV Light Disinfection Work?

Germicidal UV light has many benefits. But the most important, given the current crisis, are disinfection applications. To explain how this occurs, it is important to understand what disinfection, decontamination, and elimination actually mean according to the Centers for Disease Control and Prevention (CDC).


  • Disinfection: Disinfection occurs when a process is used to eliminate many, if not all, pathogens on an inanimate object. As with UV light elimination, the RNA and DNA of pathogens are disrupted when exposed to germicidal light. Again, this prevents their ability to reproduce, eventually leading to their death or inactivation.


  • Decontamination: Decontamination is what occurs when an object or area has been disinfected and eliminated. Because of this, UV germicidal light is a great way to decontaminate items and areas as it destroys microorganisms and pathogens without immunity.


  • Elimination: Elimination is a process through which microbial life is destroyed through physical or chemical methods. UV light elimination breaks down chemical bonds found in microorganisms. In doing so, it disrupts their regular DNA and RNA sequences and prevents the cells from reproducing. When this occurs, bacteria and viruses are no longer able to spread, therefore eliminating them.

How safe are UVGI (ultraviolet germicidal irradiation) products?
  • Unlike many UVGI products currently available, AeroCure 200 and GermZone 100 have ultraviolet lamps contained within the units, so there is no exposure of ultraviolet light to people and therefore safe to use in occupied spaces.
  • UVGI lamps have been used for many decades in the healthcare industry. UVC treatment is a known disinfectant for air, water and nonporous surfaces.
