A personal nanoparticle sampler is disclosed to include a pre-classifier, a nozzle, a particle-sizing filter pack and a final filter pack. The particle-sizing filter pack and the final filter pack respectively accommodate a particle-sizing filter and a final filter to collect nanoparticles smaller than a diameter. The pre-classifier removes large particles to avoid clogging of the particle-sizing filter pack. The nozzle raises the airflow velocity to reduce the cut-off diameter of the particle-sizing filter without increasing the total flowrate, allowing the personal nanoparticle sampler to be used with a personal sampling pump.
