Optimizing Indoor Air Quality with Science and Actionable Data

Chemistry

Our DNA-barcoded aerosols use synthetic DNA, with a unique sequence, to identify each aerosol release point. Our aerosols are water-based, non-toxic, model airborne pathogens, and can be used in occupied spaces safely.

Particle Size

Using a controlled release process for our aerosols, we are able to generate a particle size distribution of our aerosol simulants, correlating well with natural respiratory aerosol size range.

Barcode Sequences

Using multiple DNA tags in our aerosol tracers enables tracking and quantification of different release locations and iterative scenario testing under different building conditions for maximum data accuracy and granularity.

Detection

Using Quantitative Polymerase Chain Reaction, or qPCR, we are able to extract data from the collected air samples and quantify DNA concentration levels. We also use surface swabs as a secondary sampling method to complement air sampling.

Analytics

We provide heatmaps and visualized analytics for equivalent air change rates, airflow, air distribution, particle leakage and migration, and surface deposition levels, along with cost and energy modeling.
