2026 UK guidance: Measuring secondhand vaping aerosol (PM2.5) and VOCs in pubs — ventilation and monitoring best practice
The 2026 UK guidance sets out standardised monitoring and ventilation targets to control secondhand vaping aerosol (PM2.5) and VOCs in pubs. It recommends continuous PM2.5 monitoring, periodic VOC sampling, and engineered ventilation (minimum 10 L/s/person and higher ACH in busy areas) to reduce spikes that studies have shown can reach mean PM2.5 ≈197 µg/m3 during dense vaping events.
