LENOX, markets MANOA brand UVC disinfectants, products that effectively kill highly contagious and pathogenic germs and bacteria. MANOA hand sanitizers are the first to use germicidal UVCs, a technology currently in use in hospitals and other healthcare settings to help effectively disinfect operating rooms and other high-risk areas.

The MANOA is not a medical device, but it can be used to help fight the spread of infections in many settings: home, schools, healthcare facilities, restaurants, office buildings, shopping malls, etc. And, unlike other hand sanitizing options, MANOA does not leave residue behind, dry out skin, and require no recharges or batteries (just an electrical outlet).

Our goal is to provide effective and innovative products that address unmet germ and bacteria disinfection needs, while adhering to the following business principles to ensure that every product released by LENOX meets user expectations


UV-C decontamination technology.

UVC light in the form of germicidal lamps has been used since the late 1800s to kill the types of microorganisms that typically cause indoor air quality problems - bacteria, molds, yeasts, and viruses.

Soon after, UVCs were used to treat disease and disinfect municipal water supplies. After World War II, UVCs were widely used to sterilize the air in hospitals, kitchens, meat storage and processing plants, bakeries, dairies, pharmaceutical plants and animal laboratories - everywhere where microbiological contamination is a problem. Recent technological advancements have enabled UV-C disinfection technology to be deployed in an ever-expanding field of applications.

How does UV-C technology work?

The germicidal range of UV LIGHT, known as UVC, deactivates bacteria, viruses and other microbes by attacking their DNA.

UVC light is able to penetrate the cells of microorganisms and disrupt the structure of DNA molecules. Microorganisms, in turn, lose their reproductive capacity and are destroyed, rendering them inactive and no longer harmful. A cell that cannot reproduce is considered dead; because it is unable to multiply into infectious numbers within a host. The germicidal nature of UVC is well suited for treating microorganisms that become extremely resistant to chemical disinfectants, as they are unable to develop immunity to UVC light.

Electromagnetic spectrum

Ultraviolet light, especially UV-C wavelength, has good germicidal properties.

UV-C destruction of microbial DNA

UV-C light penetrates pathogenic DNA and destroys its structure to prevent its replication

UV-C has broad spectrum activity

Since all cells are sensitive to UVC, they are considered to have "broad spectrum" activity.

Viruses contain RNA or DNA and are therefore sensitive to UVC, as well as bacteria and fungi (candida). The spores are also sensitive to UVC. Alcohol-based hand sanitizers and their method of chemical disinfection have been found to be less effective in eliminating more resistant pathogens.

Short list of pathogens inactivated by UV-C

Plug in and disinfect!

MANOA is designed to produce UVC at the optimum germicidal wavelength to quickly disinfect hands and other germ-bearing objects such as cell phones, remote controls, toothbrushes, baby pacifiers, etc.

Once inserted, MANOA turns on and off automatically, while indicating the status of disinfection by display on screen and audible message. 

MANOA lamps have a lifespan of 10,000 hours. MANOA does not require recharges or batteries.

Plug in and disinfect!

Practical advantages over alcohol-based gels

In addition to its broad spectrum activity, MANOA has many other advantages over alcohol-based gels to better protect against the spread of disease-causing germs and bacteria.

  1. Works on cell phones and other objects. Cell phones and TV remotes are two of the most germ-laden items, and they can be quickly disinfected in the MANOA.
  2. Does not use harsh chemicals. No need to worry about chemical irritants and their potential side effects.
  3. Does not cause severe dermatitis of the hands. Frequent use of alcohol-based gels can lead to severe hand dermatitis, making the skin even more susceptible to infections!
  4. No risk of ingestion (accidental or otherwise). Alcohol products are naturally controversial in schools because of the risk of ingestion by children. As of 9/30/17, the American Association of Poison Control Centers reported 13,959 cases of ingestion (+ 16.3% from 2016), which can cause alcohol poisoning.
  5. Low maintenance. Alcohol-based gels require refills. And, in the case of "contactless" or "automatic" gel dispensers, battery inventories are also necessary to avoid downtime.

When to use the MANOA?

When hands are NOT visibly dirty and greasy. . .

  1. Use the MANOA to disinfect your hands when they have come into contact with a potentially contaminated surface (even if you have used protective gloves)
  2. Use before and after meals and use the toilet
  3. Use after each thorough washing of hands with soap and water
  4. Use regularly to disinfect cell phones (more bacteria than a typical toilet seat).

MANOA, UV-C technology.

We use UV-C with lamps of different powers depending on the use we want to make of them. Thanks to technological progress, today there are light-emitting diodes (LEDs) which produce UV-C, which has enabled an even greater number of applications, MANOA is an illustration of this. With a lamp power of 8W, coupled with a duration of 3 seconds, the germicidal effect is sufficient to eliminate 99% of germs without the exposure time being harmful to your hands.

The principle of sterilization of the MANOA system becomes active when an organism is exposed to UV-C light. UV-C is then absorbed into the thymine layer of the cell's DNA and destroys the alignment of the DNA, thereby killing the genetic function of the cells instantly.

Equipped with a sensor, the MANOA system turns on automatically as soon as the hands or an object are inserted. A screen display indicates the disinfection time (3 seconds) and the lamps are placed so that they are out of direct view for a completely safe disinfection solution . MANOA does not require recharges or batteries. LED lamps have a lifespan of more than 10,000 hours, or more than 5 years! The MANOA system has many advantages over alcohol-based gels, to better protect against the spread of germs and bacteria causing disease.

MANOA requires very little maintenance and no consumables, due to the lifespan of LED lamps, it plugs directly into the mains. The MANOA is not a medical device.

“The UV incident on human skin can take one of three courses, it can undergo absorption, reflection or scattering. Thus, the actual radiant exposure received by the different layers of the skin will be less than the incident exposure. Reflection does not only occur at the surface of the stratum corneum, but at all interfaces changing in refractive index. Dispersion occurs due to different structural elements, such as hair follicles and sebaceous glands, and also by cellular components, such as mitochondria and ribosomes. The remaining UV can penetrate deeper skin layers. ”
