The tiniest particles are also the most dangerous. Ultrafine particles (smaller than 0.1 microns) are so microscopic that they can move through your lung tissue, into your bloodstream and then to any organ within your body. IQAir technology in the Atem Desk filters 99% of particles down to 0.003 microns – as small as the smallest virus. Filters allergens, PM2.5, bacteria and viruses like SARS-CoV-2, the virus responsible for COVID-19. Removes airborne particles and traps them on filter materials – where they can’t escape.
