Welcome back to the great indoors

COVID-19 exposed the risks inside buildings. Science will help us reduce them.

Mask Use
Ability to Distance

Pathogen risk levels in shared spaces are influenced by three factors:

Occupant Dynamics

Number of people, duration, activity type, ability to distance, and mask use.

Building Performance

Layout and design, cleaning, ventilation, and air filtration.


Community infection and vaccination rates; prevalence of variants.

Proven science, advanced technology

ParticleOne applies building science and computational modelling to design pathogen risk-management solutions.
