Find out the answers to the most commonly asked questions about S.A.G.E. UV, how it works, and how it can help protect you, your customers, and your employees.



1. What are the benefits of Violet Defense’s S.A.G.E. UV products?

Violet Defense created the S.A.G.E. line of products because we believed there had to be a better way to keep us all safe from harmful bacteria and viruses that cause millions of people to get sick every year and unfortunately, far too many deaths. We are on a mission to bring the power of ultraviolet and violet-blue light, which kills up to 99.9% of harmful germs, to everyday spaces. Our solutions are safe, proven, and effective that can provide you an insurance policy to protect you, your family, your customers, or your employees from harmful bacteria and viruses.

2. How does UV light work?

UV light is energy at a frequency that has been proven effective at killing bacteria, fungus, mold, and viruses. When the energy hits these single-celled organisms, it is absorbed and destroys the RNA and/or DNA of the germs – leading to inability to reproduce and death of the organism. For more information, download our Guide to Understanding UV.

3. How do you know that S.A.G.E. UV works?

There have been over 100 years’ worth of research conducted on the effectiveness of UV against harmful pathogens, including bacteria and viruses. For more information, this NIH-funded study summarized key research on the effectiveness of UV.

Specifically, our S.A.G.E. UV units have been tested against key pathogens of concern for the industries that we are helping protect. Clinical validation testing from an independent, third party laboratory has proven that we can kill up to 99.9% of E. Coli, Salmonella, Norovirus, and MRSA.

4. How is UV different than other cleaning methods?

UV has a few critical benefits that help it stand apart from the alternatives.

  • Chemical-Free: UV is a chemical-free option that effectively kills the harmful germs you are concerned about. With recent studies demonstrating major health risks for long-term use of chemicals, this may help reduce the use of harmful chemicals.
  • Reliable: In 2 billion years, microbes have not built a resistance to this method of cleaning, unlike certain disinfectants that have reduced effectiveness over time as microbes adapt.
  • Consistent: Light will kill germs wherever the light touches. It’s not subject to the variation or inconsistent application of chemicals that can happen with manual cleaning. It can also help address germs in the air and on surrounding surfaces.
  • Autonomous: If using one of our installed options, there is no labor required to operate. They can run automatically when the room is unoccupied or at a pre-determined time of day that works for your business.

5. How would you recommend I use this in my space?

The S.A.G.E. UV line of products are designed to be a supplement to existing cleaning practices. Once you have used your standard cleaning protocols, the units can then be activated to disinfect the space to protect against any harmful bacteria or viruses.

S.A.G.E. UV products feature multiple programming options, including Artificial Intelligence mode. This mode works in concert with the unit’s motion sensors to detect when a room is unoccupied and automatically activates the system to begin cleaning the room. The units can also run various single-cycled options for certain lengths of time – typically 15-30 minutes depending on the size of the room – which could be manually activated or programmed to operate at a specific time each day, depending on the operation of your business. Most of our units (S.A.G.E. Micro and whole room units) are programmed to operate a 30-minute cycle each time the unit is turned on.

Note that if the space you are cleaning has any bodily fluids visible, you may want to run the units before and after cleaning the area for additional protection.

6. Do you have a solution that could help clean rooms continuously?

Our S.A.G.E. Blu units operate using LED lights in the violet-blue spectrum that are safe to run full-time. These have been proven effective against bacteria, including E. coli and Salmonella. For more information about the effectiveness of the violet blue spectrum, visit our how it works section.

7. I’ve never had any issues. Why do I need this technology?

The S.A.G.E. line of products are designed to provide an additional layer of protection to prevent issues. Even with the best of intentions, there is a high likelihood that areas will be missed or chemicals won't be left on long enough to do their job (which can be up to 10 minutes of surfaces remaining visibly wet). There are so many places in every type of space that can be difficult to keep clean using traditional methods.

There have been numerous companies out there that thought they had everything covered, but found themselves on the front page of the paper or online due to an outbreak in their business. This isn’t limited to any single type of industry. Hotels, restaurants, assisted living facilities, cruise lines have all experienced the negative effect an outbreak can have – not only in lost revenue, but long-term damage to their brand or reputation.

The question we would ask if we were in your shoes: “Is it worth the risk?”

8. In my business, my staff cleans with chemicals. How would this help us?

When thinking about your cleaning protocols, we would look at a few questions:

  • Have I tested my protocol to know that it produces the results I need?
  • How do you know your staff are following the cleaning protocols every day, including following all guidelines about length of time cleaners must stay on a surface to disinfect properly (a lot of them are longer than you might think)?
  • How do I know my staff are not inadvertently creating new problems when cleaning, such as spreading germs between locations by not changing rags frequently enough?
  • Are my staff cleaning everywhere, every day – or are there places that are rarely disinfected?

S.A.G.E. UV can provide insurance against these potential pitfalls of only using chemicals in your protocols. Our products have been tested and proven to effectively kill up to 99.9% of the key pathogens, including E. coli, Salmonella, MRSA and Norovirus. Even better, ultraviolet light will work consistently every day – killing germs everywhere the light touches.
This will provide additional protection against any potential mistakes or missed areas during your regular cleaning protocols and add disinfection to areas that may not be cleaned regularly.

9. I don’t have a lot of money for something like this. How could I justify this expense?

To put that question in context, we would compare to the alternative to simply continue your current cleaning operations and take the risk that you will not have an issue. If you own a business and were to have an outbreak, how much would even a single day of having to close down for cleaning cost your business? We are going to presume it’s more than the cost of one of our units. Not to mention the financial impact that damage to your brand and reputation could cost you in lost revenue.

For around $3/day per unit you could add an insurance policy to a room to reduce your risk of outbreaks due to improper cleaning and disinfecting of your business. Protect your bathrooms for even less per day.

10. Is this safe?

The S.A.G.E. UV units have built-in passive infrared (PIR) sensors used to detect motion in a space. If the sensor detects motion, the unit will not flash. The unit will not resume operation of the cleaning cycle until it has successfully detected the space is free of motion. If any issues are detected with the sensor, the unit will not operate. The units may also be programmed to operate at a specific time of day or via a switch so you only activate them when the room will be unoccupied for the desired cleaning cycle. Even if we didn't have these built-in sensors, there is very little exposure to UV - it is about 1000 times less than what you would get while being outdoors in the sun. The light is bright (one of the main reasons to not be in the room while unit operates), but UV can't penetrate glass, so you could safely see the unit operate if on the other side of a window or glass door.
