LAS VEGAS -- Two notable features of this year's CES, a big consumer electronics show held annually in Las Vegas, were the absence of Russian exhibitors and the Ukrainian startups looking for a recovery in business from the ravages of its war with Russia.
OptySun filters, Ukrainian startup that makes water purification equipment, was a first-time participant to CES. The company is based in Kharkiv in northeastern Ukraine, which became a fierce battleground in the conflict with Russia. One of OptySun's products is mobile water-purifier that kills bacteria using ultraviolet rays.
