Good Ventilation is Better Than Plastic Partitions
July 23, 2025
Researchers found that good ventilation is better than plastic partitions for the spread of aerosols indoors, according to a recent study published in Building and Environment. However, in the absence of ventilation, small and large partitions reduced aerosol concentrations and transmission risk.
During the COVID-19 pandemic, plastic partitions were commonly used to protect workers from any potentially infectious aerosols generated by customers or colleagues and in some scenarios (e.g. shops) these are still often in use. In preparation for a future pandemic, the researchers said it is essential to understand what protection, or risks, are created using these barriers.
The study builds on existing evidence to quantify not just the changes in airborne particles with the provision of partitions, but to incorporate ventilation for healthier environments.
