Abstract

A compact, portable, low-cost electrostatic bioaerosol sampler device is provided for collection of aerosolized biological and non-biological particles. The device may be used for long-term, large-scale deployment. With a low-pressure design, the device can sample a high flowrate of 10 lit/min with a low-power fan. The device collects dust particles with a nominal size range of 1-10 μm, with an efficiency of >60%. The device may include aerosol sensing components, a particle ionizer, and an electrostatic precipitator. A removable cassette includes a ground plate for collection of ionized particles and a high voltage plate opposite the ground plate. A divider may be included beneath the ionizer to facilitate separation of collected particles by size on the ground plate.
