Engineering and HVAC Control Verification


The American Industrial Hygiene Association (AIHA) states, “Engineering controls that can keep infectious aerosols at very low levels indoors offer the greatest promise to protect non-healthcare workers and other vulnerable populations as we reopen our businesses and workplaces.” veriDART™ identifies hotspots, assesses ventilation and filtration systems, and informs critical decisions on occupational health and capital expenditures with empirical data.

Create Safe Spaces in a Changing World

Scientists and public health officials acknowledge that SARS-CoV-2 is airborne. AIHA and ASHRAE highlight the importance of engineering and HVAC controls, particularly ventilation and filtration, to reduce airborne exposures indoors. However, safety and facility professionals face overwhelming, confusing, and highly consequential decisions without the ability to validate and verify which engineering and HVAC controls are appropriate for their own buildings.

The veriDART Solution

veriDART is the first and only liquid aerosol-based solution for verifying engineering and HVAC controls in order to mitigate viral spread indoors. veriDART’s proprietary airborne tracers safely mimic the chemical composition, mobility, and effect of ventilation and filtration for aerosol contaminants.

  • Survey Test: Verify aerosol mobility and airflow patterns in order to identify hotspots and inform remediations
  • Dilution Ventilation Test: Verify time and HVAC settings for aerosol dilution under multiple scenarios in order to inform decisions on ventilation, filtration, and airborne interventions
  • Filtration Test: Verify filtration efficacy at different MERV-levels in order to audit existing systems and inform enhancement decisions
