Where particulate monitoring matters
Theatre suites, neutropenic wards, cleanrooms, ICUs and respiratory units are primary candidates for continuous particulate monitoring. Outpatient and general ward areas benefit from periodic surveys, particularly where ventilation is older or where the building sits in an urban high-PM environment.
Instrumentation and method
We use reference and reference-equivalent optical particle counters for surveys and validated fixed sensors for continuous monitoring. Counts are typically reported as PM2.5 and PM10 mass concentrations, with particle-count channels for ISO 14644 cleanroom classification where relevant.
Interpreting healthcare particulate data
Healthcare benchmarks are tighter than office indoor air quality guidance. WHO annual PM2.5 guidance and the ISO 14644 cleanroom classes both inform our thresholds, alongside the room's clinical risk classification. Exceedances are investigated against filter condition, external air quality and recent works.
