Protection from airborne pathogens using eye and skin safe, 222nm Far-UVC
*Sorry, we can no longer send to Canada.
Suggested use:
Assuming no more than four hours of use in a single day, and an approximate room size of 9-12m², each lamp should be positioned no closer than 50cm away from a room occupant. The more widely the lamps are spread, the more air volume will be exposed. If there are children or pets present, the lamps should be placed well out of reach.

Description:
The germicidal properties of ultraviolet light are well established and have been in use for almost 100 years, but that effectiveness has always come at a price- the potential for eye and skin damage. Far-UVC, the portion of the ultraviolet spectrum that ranges from 200nm to 230nm is often described as “eye and skin safe” but is perhaps more accurately described as “safer”. There is still an exposure limit- just much, much higher than with other portions of the UV spectrum.
Because of its relative safety, Far-UVC technology has tremendous potential and has attracted companies engaged in dishonest, even dangerous, marketing practices. Selling lamps that are not filtered so emit at unsafe portions of the UV spectrum above 230nm, that are far too low powered to be effective, or that make inflated claims of efficacy- including that Far-UVC is comparable to wearing a well-fitted N95 mask (it is not) or a substitute for upgraded filtration and ventilation in buildings (it is not).
New Far-UVC guidelines are being developed, and new products are being brought to market. For now, the safest way to use Far-UVC is as an additional layer, and not change your behavior because you have access to Far-UVC. We all have to eat anyway- eating with Far-UVC is safer. We have to go to the dentist anyway- going with Far-UVC is safer. Children need birthday parties and playdates- and even with kids old enough to mask, those masks slip or can be dislodged. With carefully positioned Far-UVC, these activities are safer. But if we are going to take a long flight- having a Far-UVC device is not a reason to fly unmasked. Far-UVC is a useful layer on top of masking, and adds a measure of safety, but it should never be considered justification to unmask in situations you normally would wear one. (If you have trouble finding a comfortable mask, we recommend the CanadaMasq Q100.)
Early on in the pandemic, it was hoped that a single, small Far-UVC device could offer “near-field” protection- create a zone of light around a person that would destroy pathogens before they were inhaled. Devices- including wearable ones, were made and tested, but in the end, the math for a single small emitter, providing any near-field protection, just does not work.
Pathogens need to be exposed to a certain amount of energy to be inactivated- joules or power over a given duration. A single 3-watt, low-power Far-UVC emitter does not have enough time to inactivate airborne pathogens to a significant degree before they are inhaled. If you increase the power- and so shorten the exposure time needed, it is no longer safe to have the emitter immediately next to the user for hours or days at a time.
When using Far-UVC, our goal is to get as much power (joules) into air volume as possible without exceeding the daily exposure limits of the occupants- so you need to avoid “hot spots” created by high-wattage Far-UVC emitters. Diffusing lenses are one way to spread the light more evenly throughout a room; another is using an array of small Far-UVC emitters instead of one or a few large emitters- and that is what the Mini Far-UVC kit does.
The Mini Far-UVC kit is sold as a package of four battery-powered, three-watt Far-UVC emitters with a carrying case and USB charging cable. That is a total of 12 watts- the minimum that would have an effect in a small (9-12m²) room.
12-watts, for a few hours a day, is also a very safe dose of Far-UVC that people can be trusted to self-administer without professional UV meters and installation equipment or issues involving secondary compounds that might arise with fixed, higher wattage installations intended for continuous use.
The set of four emitters are intended to be placed throughout a small room to expose a large volume of air without creating hot spots of potentially high exposure. They are not sold individually because one, 3-watt emitter simply would not have any meaningful effect based on the data we now have. If anyone tries to sell you a single 3-watt UVC emitter as any kind of mitigation tool- you are being scammed. The data simply does not support it at present. Please do not split up the set or share individual units- they are designed to be used together.
The price for four Mini Far-UVC lamps is the same price as just one of the competing portable lamps of comparable power. At the moment, this Mini Far-UVC kit offers the lowest price per filtered watt of any battery-powered Far-UVC emitter. It is an imperfect solution- but during its 3000-hour operating life, it should offer a meaningful layer of additional protection and bridge the gap until we have more solid guidelines.

My husband and I just used our Nukit torches for the first time, as he had surgery.
I set the four torches out in the recovery room and left them on until we were ready to go. This added a layer of protection for us both and was especially important for my husband, who had to briefly remove his mask to eat, etc.
I think the torches went unnoticed. They're small and unobtrusive, especially in a medical setting, where they blend in. I really like the look of them - an added bonus.
The battery indicator is right on the front, so it's easy to see how much battery is left without having to pick them up or move them. They pack away quickly into a sleek case.
We also used them in the hotel the night before: all four in the bathroom for about an hour before moving them into the main room.
I bought a UVC/far-UV beam detector when I thought I'd have to chance buying a 222nm light of unknown brand from a big reseller (so glad I found these instead!). The detector lights right up in Nukit's beam.
Having small, portable, unobtrusive lights that don't require a huge stand is fantastic.
Having them at all is more than fantastic! I never thought I'd be able to. Now I have these thanks to the maker keeping prices as low as possible. How rare is that these days? Or any days? Many, many thanks!
So glad I received my set of torches before an unavoidable overseas trip.
Easy ordering process, excellent customer communication, and short international delivery times for a high-quality product you won't find elsewhere at such an affordable price.
The torches are easy to use, and I love the neat case that comes with them.
There was honest interest, but no problems at airport security when mentioning they are UV lamps.
Knowing that air quality is a real issue on airplanes especially before takeoff (and with about one in four passengers coughing or sneezing), I felt much more comfortable flying with the torches. My personal setup includes a high-quality respirator, personal HEPA filter, and from now on also these UVC torches as an additional layer of protection.
I'm convinced long-term mitigations can only succeed by cleaning indoor air. Until this becomes standard in public indoor spaces, Naomi is a real pioneer providing such innovative tech for personal use.
Loved these so much we got another set. Easy to use everywhere from the home when people over to hotels to medical appointments given the small size and really light weight. Come with a perfect travel case. Last for close to 4 hours on a full charge. Bonus aspect is the person behind them is committed to trying to make tools like this more affordable and accessible for everyone. Total badass.
These torches gave me the courage to go to the dentist for the first time since the beginning of the pandemic. Thank you so much. They are practical and well-designed and I may have convinced my dentist to buy some, too.
We use Nukit Torches to make rehearsals safer. Loving the added layer of protection. Thank you Nukit!!

This Far-UVC torch set is great because they are small, lightweight, and easy to use in a multitude of situations. They are added protection for us when we are masking, traveling, and especially when we cannot wear a mask (dentist office, etc.).
Product arrived well packaged with thoughtful documentation on how to use as well as how to learn more. It's clear that safety is a high priority to Nukit which makes me rest easier when using these torches. Thanks to them (in addition to other precautions like masks) I felt comfortable receiving in-home care for my wife who is high risk. Thanks for what you do, Nukit!
I thought this was a cute keepsake. As always, Cyber Night Market exceeds expectations. The packaging was beautiful and the product is high quality.
Amazing tech at a price affordable to regular people.
Our family’s been using these torches as an extra layer of protection alongside ventilation and air purification, as we were able to prevent household-wide spread when one of my kids tested positive for COVID. I am so very grateful for the wealth of information provided on this product and research behind it. Many thanks, Nukit!
Portable, reliable, and rugged. It's hard to know how effective this sort of thing is, but I had these running through a whole bunch of holiday gatherings with relatives who can't be bothered to mask anymore, some of whom have small children, and I didn't get sick at all, so that's a good sign at least.
I’m so happy with my Nukit torches. They are another layer of safety for both myself & my dental hygiene patients. Thank you so much for producing them. 🙌🏻
An amazingly innovative and portable extra layer of protection for airborne pathogens. Nukit has made this product affordable, is transparent with data, and operates with integrity. I use the torches at the dentist where masking is impossible and anytime I need to supplement masking and air filtration. Thank you for your community care.
Finally took the plunge on a purchase last December, and I've been very glad that I did. The torches are elegantly designed and well-packaged for portability. My family and I use them as an added layer, in addition to air cleaners (HEPA or MERV13 filter boxes), when hosting dinners in our home. We have also traveled with them to use during the first several hours in a hotel room or when unmasking indoors can't be avoided (i.e. medical appointments).
The Nukit Torch far-UV lamps have been a wonderful addition to the layers of mitigation I have employed during this pandemic. They have allowed me to have my parents over for a safer dining experience. They also allow me to eat my lunch at work in a shared office when I am too tired/busy to go out to the car. Torches seen on my workstation are discreet and highly portable. Thank you for all the work you have done to design, build and promote this product. That's leadership!
