Ultrafine particles (UFPs) are particulate matter of nanoscale size (less than 0.1 μm or 100 nm in diameter). Regulations do not exist for this size class of ambient air pollution particles, which are far smaller than the regulated PM 10 and PM 2.5 particle classes and are believed to have several more aggressive health implications than those classes of larger particulates.
