Healthy air requires viral-risk interventions
A simple, validated, science-first solution to managing viral risk
Developed and used by world-class building-performance engineers and scientists at RWDI, ParticleOne is a cloud-based platform that measures and monitors specific airborne risks within a building, based on use, location, and ventilation systems. Factoring in the latest epidemiological data, it creates clear, evidence-based mitigation plans as needed, which are customized for each space.


Validate air quality. Reduce viral risks.
