“Alfaa UV Launches Mobile UV sanitizer STERO 360”

Alfaa UV recently introduced Stero 360, a high-performance mobile UV sanitizer, to address the rising demand for hassle-free touchless and non-chemical disinfection solutions especially during the COVID-19 pandemic.

As per a release, STERO-360 uses Ultraviolet Germicidal Irradiation (UVGI) disinfection method in which the sanitizer emits short-wavelength ultraviolet (ultraviolet C or UV-C) light to inactivate microorganisms by disrupting their DNA, hence destroying the ability of the microorganisms to reproduce and thereby effectively killing them.

The release cites global clinical studies which reportedly mention that UV-C light can combat the novel coronavirus as UV-C falls in the range of 200nm to 280nm of the ultraviolet light spectrum, which is known to eradicate micro-organisms, viruses, bacteria, yeast, molds, fungus, etc., in air and on surfaces. The chemical-free technology is known to kill 99.99 percent of all pathogens with no residue or by-products.

An organism must receive the correct UV dose for it to get inactivated. The mean UV-C dose requirement for the coronavirus group of organisms (of which COVID-19 is a part) is 26,000 uW-sec/cm2 for a 4 log (99.99 percent) kill rate. STERO 360 is designed to provide a 50,000 uW-sec/cm2 dose to a target surface at a distance of 1.8 meters and height up to 2.5 meters within 2.5 minutes.
