Healthcare professionals around the world are responding to a pandemic of respiratory disease spreading from person-to-person caused by a novel coronavirus. The virus causing coronavirus disease 2019 (COVID-19) is not the same as the coronaviruses that commonly circulate among humans.
COVID-19 has prompted researchers, manufacturers, and consumers alike to search for practical solutions that can prevent the spread of this deadly virus. Crystal IS- manufacturer of1Manbetx
and systems for disinfection- has seen a surge in interest for our high-performance UVC LEDs to potentially combat the virus. This page provides answers to common questions about Klaran UVC solutions for disinfection and COVID-19.

What is COVID-19?
Severe Acute Respirator Syndrome Coronavirus 2 (SARS-COV-2) is the newly discovered coronavirus responsible for the 2019 novel coronavirus disease (COVID-19). This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.
How Does COVID-19 Spread?
According to the CDC, Coronaviruses are generally thought to spread from person-to-person through respiratory droplets. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.
How Do UVC LEDs Disinfect Pathogens
UVC能量被RNA和DNA内的核酸吸收，导致在右剂量的共价键可以使病原体不能再现和感染。这most effective germicidal wavelength occurs with a peak between 260 nm to 270 nm, the point at which DNA absorbs UV energy the most.
UVC能量是一种常用的灭菌技术，已被证明是灭活各种病原体（例如MRSA，C.差异，大肠杆菌和假单胞菌）。多年来，紫外线汞灯被认为是最佳选择。然而，灯具有几个限制，包括在制冷温度下的低活动，脆性建设，长的预热时间，汞暴露的风险，以及254nm的限量紫外线发射。相比之下，UV发光二极管（UV LED）可以被配置为以理想的杀菌波长发射，并提供可靠的按需消毒，而不会妨碍汞灯的限制。
Are UVC LEDs Effective Against COVID-19 (Coronavirus)?
Crystal是与波士顿大学国家新出现的传染病实验室（Neid1）的一项研究，以了解SARS-COV-2如何在克拉·UVC LED（260nm至270nm）的排放范围内响应紫外线和不同剂量。新万博客户端万博捕鱼手机游戏将病毒暴露在5 mj / cm2dose of UVC light at 268 nm resulted in a 2.8 log reduction of the virus. Read more about the results of this study,here.
Can UVC LEDs be Used to Disinfect N-95 Filter Respirators?
In general, this is not recommended, as notedhere. Healthcare providers should contact respirator manufacturers for specific guidance and recommendations on whether and how to disinfect Filtering Facepiece Respirators (FFRs).
但是，CDC发布了关于在流利期间管理呼吸器的指导，包括重用和扩展呼吸器的使用。虽然研究表现出对这些呼吸器的拟合造成潜在损害，但几项研究表明了UV杀菌辐照辐照降低病毒载荷的有效性。[1,2,3]
Most recently, the University of Nebraska developed an N95 Filtering Facemask Respirator Ultraviolet Germicidal Irradiation (UVGI) Process for Decontamination and Reuse (source).
What Products Available Today Can Help to Combat COVID-19?
世界各地的oem厂商的信任Klaran WD系列UVC LE万博捕鱼手机游戏新万博客户端DandKlaran LEto provide effective surface disinfection in their products. For example, LED Tailor’s WiSDOM DS disinfection box-which is marketed to healthcare facilities- features Klaran UVC LEDs to combat dangerous pathogens on handheld devices. Similarly, Klaran UVC LEDs are used in the CX1 disinfection cabinet by Cleanbox to disinfection hardware and other products with personal touch points.
