Acer “antimicrobial” laptops have been around for a few years, but they became particularly relevant during the COVID-19 pandemic. During its next@Acer event today, the company announced three new PCs—a laptop, a two-in-one, and a tablet—that will be joining its antimicrobial lineup.

Something is considered antimicrobial if it's capable of "destroying or inhibiting the growth of microorganisms and especially pathogenic microorganisms." That means it fights disease-causing things you can't see.
