What healthcare air quality testing measures
A healthcare air quality test typically covers PM10 and PM2.5 particulate concentrations, CO₂ as a ventilation marker, total VOC load, temperature and relative humidity. In higher-risk areas we also assess HEPA filter integrity, pressure differentials between spaces, air change rates and microbial contamination where indicated. The exact protocol is set by the room's function and the relevant section of HTM 03-01 — what is appropriate for an outpatient consulting room is very different from what is required in a neutropenic ward or theatre.
How a healthcare testing visit runs
Tests are scheduled around clinical activity to avoid disruption. Our engineers deploy calibrated reference-grade instruments at the patient zone and at key supply and extract grilles. Measurements run for a representative occupied period so we capture real-world conditions rather than commissioning-only data. Findings are written up with clear pass/fail status against the applicable benchmark, photographs of plant condition where relevant, and a prioritised remediation list.
When healthcare air quality testing is required
Typical drivers include statutory ventilation verification, post-refurbishment commissioning, change-of-use of a clinical space, suspected infection clusters linked to a ward, complaints about odour or thermal discomfort, and routine annual validation of critical ventilation systems. Where the trigger is an infection or contamination concern, testing is paired with a healthcare environmental risk assessment.
