Abrégé

A method, system, and computer program product for managing particle concentrations without human intervention before, during, and after a respirator fit test. One method includes controlling power to a particle generator to establish a target particle concentration in a breathing zone of a respirator fit test subject, collecting particle concentration data, analyzing the particle concentration data, and controlling, in real time without need for human intervention, power to the particle generator to maintain the target particle concentration.

Abrégé

Improved respirator fit test devices including piezoelectric pumps that reduce noise and vibration of the device. The devices may include two or more piezoelectric pumps, wherein a first pump moves sheath air through a differential mobility analyzer and a second pump alternately moves aerosol from inside or outside a respirator through the differential mobility analyzer. A size selected portion of each aerosol sample is then moved through a condensation nuclei counter. Control circuitry enables user selection of a respirator type to be tested, wherein the differential mobility analyzer may be enabled or disabled based on the user selection. The control circuitry further enables calculation of a fit factor corresponding to a quantitative effectiveness of the respirator fitting a user based on signals from the condensation nuclei counter for each aerosol sample.
