UVC Light Treatment For  Coronaviruses. Any potential for Sars-Cov-2 disinfection?

UV light,  between 200-280nm was found to inactivate  at least two  coronaviruses related to the novel Sars-Cov-2  virus: SARS-CoV-1 ‎[4]and MERS-CoV ‎[5], ‎[6]. It should be mentioned that this inactivation has been shown under controlled conditions i.e. in laboratory settings. The effectiveness of UV light in practice will depend on various  factors including the exposure time and the ability of the UVC rays  to reach these viruses in water, air, and on various materials and surfaces.

UV Light Disinfection. Safety concerns

UVC rays are safely used on various surfaces, but humans should limit the exposure to them. UVC rays can cause skin and eye damage. Although research found that UVC rays within a specific range do not cause skin damage ‎[1], humans should avoid exposure, and this therapy should be used on various surfaces and spaces only. 

Pulsed UV light treatment Versus Continuous UV Light Treatment

Pulsed UV light treatment is more effective and rapid for microorganism inactivation than continuous UV light sources  [7]. 

Pulsed light technology  has received significant  attention as a strategy for decontaminating food, packaging, water and air and could also be used to decontaminate surfaces in hospitals. Pulsed UV light has the ability to  kill micro‐organisms by using ultrashort‐duration pulses of an intense broadband emission spectrum that includes UV‐C germicidal light (200–280 nm band) ‎^[3]

The PXL Sanitizer Advantage : Effective UV Light Disinfection for Bacteria and Viruses

The PXL Sanitizer uses enhanced pulsed UV light to disinfect surfaces from bacteria and viruses. It could be the ideal option for disinfecting surfaces in the food and beverage industry, where multiple tools are shared in kitchens and other spaces that contain food and drinks. This device can be easily installed above the surface that has to be disinfected (ie fridge, counter tops). It can also be used to disinfect handles, toilet seats, keyboards/mice, plates, pens, remote controls, and more. It is user friendly and has a compact design, using battery power or direct electrical connection. When turned on, the PXL sanitizer will illuminate the surface that has to be disinfected.

 PXL Sanitizer- UV light disinfection effectiveness. PXL Santizer  was tested  by a third-party analytical microbiology certified laboratory, which found that this device is highly effective and can virtually eliminate bacteria with antibiotic resistance. “On a surface with 65 million bacteria cells with antibiotic resistance, less than 1000 cells remained after 30 seconds of illumination with the PXL Sanitizer. After 5 minutes of illumination, only 6 cells remained”.
