This review summarizes existing research on microplastics floating in indoor air, finding that synthetic textiles, flooring materials, and increased use of plastic protective equipment since the pandemic are major sources. Indoor microplastic levels can be higher than outdoor levels, and inhaling these particles has been linked to respiratory, immune, and nervous system concerns. The findings highlight that people face significant microplastic exposure simply from breathing the air in their own homes and workplaces.
