“Thanks to our pioneering HepaSilent technology, our air purifiers have a superior performance even at lowest speed, said Alexander Provins, Director Europe. “I’m not surprised that our Blueair Classic 405 was awarded top scores in the Which? test. It is rated “Best-in-Test” in the UK by Testfakta and is our most popular product among consumers.” added Provins.
