FAQ's

Q - How does UV Personal Wand Work? 

UV light comes primarily from the sun, but there are also man-made sources of UV light, including tanning beds, UV disinfection lamps and more. 

There are three classes of UV light: UV-A, UV-B and UV-C.

UV-A and UV-B light cause sunburns and premature skin aging, and exposure to both is associated with the development of skin cancer. UV-C light, which has the most energy of all three types, is the most harmful, but it fortunately doesn't reach the Earth's surface because our atmosphere absorbs it. 

There's man-made UV-C light, too: It's what's in our Personal Wand sanitizers. According to the National Academy of Sciences, it's probable that this is true, because UV light has been used to disinfect surfaces and water for a long time.

It works because UV-C light is strong enough to destroy the genetic material -- either DNA or RNA -- of viruses and bacteria. There's no evidence right now that typical sun exposure can kill the coronavirus, so going outside on a sunny day won't reduce your risk of catching it.

Does the UVC Personal Wand affect the covid 19 virus?

The sanitizing effects of UV lights have been seen with other coronaviruses, including the one that causes severe acute respiratory syndrome (SARS). Studies have shown that it can be used against other coronaviruses. One study found at least 15 minutes of UVC exposure inactivated SARS, making it impossible for the virus to replicate. New York’s Metropolitan Transit Authority announced the use of UV light on subway cars, buses, technology centers, and offices. The National Academy of Sciences says although there is no concrete evidence for UV’s effectiveness on the virus that causes COVID-19, it has worked on other similar viruses, so it would likely fight this one too.

Since the interest in UVC spiked, Amazon announced the creation of an ultraviolet robot: a metal frame on wheels equipped with ultraviolet tube lights, meant for use in Amazon warehouses and Whole Foods stores. Other products, like our Personal Wand are meant for at-home and travel use. 

Q: What are uses for the Personal UV Wand?

In general, UV sanitizing wands have been shown to work about as well as a Clorox wipe at killing bacteria and viruses on smooth nonporous surfaces like airplane tray tables, for example. Suitable for office use and travel. Maintains cleanliness in the room, closet, and household items. Lightweight and convenient hand-held design can sterilize the required area at any time.. Used in personal daily necessities, spoons, cutlery, telephones, desks, toilets, public places, cars, etc., to avoid the harm of germs and bacteria. See more guidelines below. 

Q: How much intensity do I need to kill organisms?

The exposure of ultraviolet is the product of time and intensity. High intensities for a short period and low intensities for a long period are fundamentally equal in lethal action on bacteria. The inverse square law applies to ultraviolet as it does to light: The killing power decreases as the distance from the lamps increases. The Personal UV Wand is low intensity for both safety and convenience-carrying reasons. Specifications are contained here.

Q: How do I know when my Personal Wand is fully charged?

The light changes from Red to Green and you are good to go. Charging usually can be accomplished in less than 60 minutes. We recommend charging after each hour's usage of the Personal Wand.  

Q. How do you measure UV effectiveness?

The effectiveness of germicidal UV depends on the length of time a microorganism is exposed to UV, the intensity and wavelength of the UV radiation, the presence of particles that can protect the microorganisms from UV, and a microorganism's ability to withstand UV during its exposure. The Personal Wand has low intensity and thus will take longer to achieve a 90.00% and above kill rate. But, closeness to the surface will speed the process and provide comfort in knowing bacteria and virus issues have been addressed, and each time you wave the wand above the surface, you are destroying some percentage of the harmful bacteria.   

Q - Is there any way to predict how long it will take to kill 90% of bacteria on a particular surface?

If you look at our specifications, loosely translated and rounding from centimeters to inches, our Personal Wand, from a height of 1 to 2 inches, will kill close to 99% of all bacteria in 15 seconds in a 2 inch square range. 

Now that is in a perfect world, with the wand held exactly where you want, not tilted, without any extra mass on the object you are sanitizing, how quickly you are moving the wand over the surface, and many more variables. Here are some rough estimates that should be used as guidelines only, because of the many variables that can come into play: But, they will give you a road map for how to use. 

• For Bedding/Mattresses: Hold the UV-C Light Sanitizing Wand approximately 1-2 inches from the surface and gradually move the wand over the entire area. Allow the light to stay on each area for 5-10 seconds to ensure optimum exposure, per the description above.

• For Personal Hygiene items (hair brushes, toothbrushes, jewelry, razors): Place items on a counter, away from water. Hold the UV-C Light Sanitizing Wand approximately 1-2 inches away from each object. Expose each object to the UV-C light for 10 seconds.

• For Kitchen Utensils: Place items on a counter, away from water. Hold the UV-C Personal Wand approximately 2-3 inches away from each object. Expose each object to the UV-C light for 10 seconds.

• For Counters/Bathroom Fixtures: Hold the UV-C Personal Wand 2-4 inches above the surface. Expose the counter/fixtures to the UV-C light for 10-20 seconds.

• Other uses (computer keyboards, telephone handsets, baby toys, etc.): Hold the UV-C Personal Wand 2-4 inches above the surface. Expose the items to the UV-C light for 10-20 seconds.

*** - These numbers are estimates and guidelines and do not imply specific numeric performance. You are free to wave the wand longer to insure better bacteria removal.

**** - In all uses, keep Personal Wand light away from skin and especially, eyes.
