This is a simple device that takes AC mains power and turns it on or off depending on the ambient CO2 levels in a room. The purpose of this is to address indoor air quality issues with filtration or ventilation while also being conscious of energy use.
The Nukit CO2 Controller uses an extremely accurate NDIR CO2 sensor (the Sensirion SCD40) on a convenient, 3-meter cable.Suggested use:
Use one, CO2 Controller in each room. The best way to keep CO2 levels low indoors is ventilation- a shuttered exhaust fan, or fans adapted to sliding windows can be connected to the Nukit CO2 Controller and will turn on and off when the set CO2 levels are reached.
The next option is to connect the Nukit CO2 Controller to an air filter like our Nukit Tempest.
Filtration will not lower CO2 levels- it can only reduce the level of pathogens in the air and lower infection risk. When there are fewer people in the room, the CO2 level will drop of its own accord, the infection risk will be less, and the CO2 Controller will turn the filter off.
Setup:
Indoor CO2 levels should always be under 1000ppm. Between 600-800ppm may be difficult to achieve without significant energy use from an exhaust fan or filter running continuously, but it's worth trying. "Current Conc(entration)" in red shows the current CO2 level in the room.
Set the "Start Conc(entration)" on Nukit CO2 Controller to turn on at 800ppm, and the "Stop Conc(entration)" to 600ppm, using the blue arrow buttons. When you are finished, the display will look like this:
This means AC mains power will flow to the outlet on the Nukit CO2 Controller when CO2 levels reach 800ppm, and power will stop when CO2 levels reach 600ppm.
If you find the fan or filter your Nukit CO2 Controller is connected to never turns off, you might need to raise your threshold to 1000ppm to 800ppm. Using the arrow buttons, your display will look like this:
Your Nukit CO2 Controller will turn on (Start Conc) at 1000ppm, and off again (Stop Conc) once CO2 levels drop to 800ppm.
Avoid making the high and low threshold numbers closer than 100ppm or you will find your air treatment device turning on and off fairly quickly- which could shorten it's life.
There should be no need to turn the Nukit CO2 Controller off at night or when the space is unoccupied. With no one there, CO2 levels will stay low and your air treatment device will not cycle on.

Perfect for air travel! Just wish for a longer battery life.
I am extremely pleased with my Nukit FAR-UVC torches. Extremely lucky, too, as I understand that the Cyber Night Market can no longer ship to Canada, so it seems I got in just ahead of that sad news.
They are easy to charge and use, and people are interested wherever I take them.
Thanks, Nukit!
I purchased Nukit torches as an extra layer of protection against COVID. The fantastic support and communication about its safety and capabilities on the product page and X from the creator are what sold it to me!
Since making the purchase, I've been using torches mostly at home to meet friends. However, recently I took them for a ride. I went on vacation and used it inside the airplane – CO2 levels were bad, so I was very happy to have the torches at hand!
I also put the torches to work in the hotel each time after housekeeping was in my room – the window alone was not enough to ventilate well, so the torches were very useful. With them, I felt confident that all housekeepers left in my room was cleanliness and not viruses :)
I also loved the bag that Nukit sent along with the torches. When I traveled with it, I was able to fully appreciate how sturdy and useful it is for safely and compactly transporting the torches.
I always take my Nukit Torches with me as an extra layer of protection in situations where I won't be able to keep my mask on, and I'm so happy to have these in my toolkit. The Torches are well made, lightweight and easy to use with lights that indicate the level of charge. They come with a soft carrying case with adjustable velcro dividers and a 4-headed USB cable, so carrying and charging them is really easy. All in all the Nukit Torches are excellent value for money and I would recommend them to anyone who is considering using Far-UVC. Thank you, Nukit!
Extremely happy with my purchase. Long battery life and resilient construction that can survive being accidentally knocked down. Handy carrying case. Unfortunately, my silly country of Canada now considers these a “pest control” product so here’s my dog being brainwashed into breathing cleaner air at the vet. Thank you, Nukit!
I am planning on traveling this summer, but with COVID and other viruses continuing to spread out of control, I need all the protection I can get. I tested these out after arrival and they did wonders cleaning up the air in their vicinity. In tandem with HEPA air filtration, they work to help mitigate the spread of airborne pathogens. The torch kit is affordable, well made, and functions as advertised. No lies or exaggerations about what they can and can't do, which is refreshing.
Very easy and safe to use, fantastic quality and at a price ordinary mortals can afford.
I have read a lot about UVC & far-UVC and am happy they are adding a useful layer to my protection (I'm still a Novid!)
We love our Nukit Torch Far-UVC lights! I am so happy to have these lights as an additional layer of protection for our family members against Covid-19 infections. The design is elegant and they are easy to use discreetly in various settings. (Visiting friends and family, small social gatherings, business meetings, while travelling, etc.) Love the slim protective storage case and the multi-prong USB-C cord that simplifies charging all four lights at once. Ordering was easy and shipping to Canada was fast. Excellent customer service. I have recommended Nukit Torch Far-UVC Light kits to friends going on trips and travelling on airplanes. My friends who purchased them were also happy.
I love these little torches. Adds a layer of protection to keep us safer.
Very quiet. Easy to put together. Zero complaints.
Easy to charge and use, and I appreciate the detailed explanation and testing… thank you, Naomi!
Easy to charge and use. Low profile, and love that it comes in its own carrying case with all the cords needed tucked in. Great added layer of protection along with masks and sprays.
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!
