Earlier this year – and soon after the start of– Kentucky-based producer Big Us Fans Introduced A great smart sealing fan with the purpose of disinfecting and sealing ultraviolet lights built into the base. The pitch was very beautiful at times – as the fan transmits air throughout the room, those UV lights hit the airways that cross their path.
Now, after several independent tests in accredited laboratories, the company tells Tips Clear that the fan – which starts at about $ 1,750 – can kill SARS-CoV-2, which causes the pathogen COVID-19.
“In relation to the aerosol test we saw a decrease of about 48% [of airborne SARS-CoV-2] Reduced by about 86% over the fan in 5 minutes and over the fan in 10 minutes, ”reads the cover letter to the test report written by Kevin Noble, COO of Innovative Bioanalysis, the California lab that tested the fan against the coronary virus. ” It can be concluded that there was a total reduction of 99.99% or more between 10 and 20 minutes. “
The letter, which Big Us fans shared with Tips Clear, ends with an endorsement for the efficacy of ultraviolet light against COVID-19.
“Regarding whether your technique works to discredit SARS-CoV-2, I would say that you can clearly state that the pathogenesis in the air passing over the fan and through UVC is actually UV light. Are negatively affected by, “Noble’s letter. It ends.
now with, The Big Ass fan, is set to market this fan as a COVID-killer.
“Big Lab CEO Lenny Roheads said,” Our work with independent laboratories allows us to verify the lack of harmful viruses and the lack of SARS CoV-2 and other pathogens and volatile organic compounds. “These third-party results give our customers confidence that the clean air system will protect their people and businesses.”
UVC and Security
Safety is an important concern with ultraviolet light. Simply seated from the visible light spectrum, UV light comes in three types: UVA, UVB and UVC. The first two are strong enough to burn your skin if you’re out in the sun too long, but UVC is the strongest, and is able to burn the eyes and skin within seconds. It is also a known carcinogen.
Fortunately, the UVC light produced by the sun is almost completely absorbed by the Earth’s atmosphere – but a disinfectant has caused a flood of new products to bring invisible light to homes and businesses due to renewed interest in UVC’s capabilities . It is led by security scientists– Especially with handheld UVC wands that glow openly during use.
Todd Straka, global industry director of lighting for Underwater Laboratories, said, “Under the epidemic, we have seen a considerable increase in interest about UV disinfectant type devices, which now have more consumers to face”. Tested for security certification. “These can be very dangerous if you don’t use them properly.”
The same safety scientists told Tips Clear that they are less concerned with upper-room disinfectant products like Haiku UV-C that use UV light to clean the air above eye level – although they made some additional guidelines Was offered
“The concerns that still need to be mitigated are making sure it is installed correctly, that it is the required distance from the floor where the light is [at least 7 feet], And UV lights are not up and down from that perspective, “said Pamela Gwinn, UL’s chief engineer for life and health sciences related to medical devices.
To that end, Big Ass fans state that each Haiku-UVC has been installed by a trained technician from its network of professional dealers, and that fans have been certified by Intertech to comply with North American safety standards . The company says that UV lights can be switched off independently of the fan, and they automatically turn off whenever the fan is off. This makes way for safe maintenance and cleaning.
From lab to class?
Big As Fans tells Tips Clear that it is seeing interest in haiku UV-C from a wide variety of homes and businesses across the country, adding that it is testing the fan for efficacy in various environments. It includes test chambers designed to mimic the living room and bedroom – but also places such as break rooms, restaurant dining areas, and even classrooms.
A test, which measured the efficacy of two fans spinning in a classroom environment contaminated with SARS virus, found that UVC lights would reduce the student’s risk from 39% to 5% during a 60-minute class. For a teacher who spent seven hours in a room during the day, the exposure risk dropped from 97% to 30%.
Big As Fans says Carnegie Mellon University is among the schools that have added Haiku UV-C fans to their classes, and says the list is growing.
“A big-ass fan spokesman said that down to small Kentucky school districts and anywhere in between,”. At least some of them were purchased with the help of government money through the CARES Act, although the company notes that customers are not obligated to share that information with them.
Big Ace fans told Tips Clear that it has no immediate plans to create a less expensive version of the fan, and says its focus is on businesses and public organizations currently looking for ways to protect people in shared spaces. Along with Haiku UV-C, the new clean air system line of the company’s disinfectant offerings includes large industrial fans and floor fans equipped with disinfectant ions. They, too, have been tested for efficacy against COVID-19, with results promising as haiku UV-C.
A company spokesperson said, “Ideally, someone calls and says, ‘We will help you with air disinfection.” “We then assess space, specs, application and determine the correct technique to implement based on other goals.”
Translation: Don’t expect to see a budget-friendly version of these fans anytime soon – but don’t be surprised at the end by watching a spinning overhead when you’re out or about.
