Abstract

Methods and devices to determine rate of particle production and the size range for the particles produced for an individual are described herein. The device (10) contains a mouthpiece (12), a filter (14), a low resistance one-way valve (16), a particle counter (20) and a computer (30). Optionally, the device also contains a gas flow meter (22). The data obtained using the device can be used to determine if a formulation for reducing particle exhalation is needed. This device is particularly useful prior to and/or following entry in a cleanroom to ensure that the cleanroom standards are maintained. The device can also be used to identify animals and humans who have an enhanced propensity to exhale aerosols (referred to herein as 'over producers', 'super-producers', or 'superspreaders').
