Verifying Cost Efficient Indoor Air Quality

The veriDART® Performance Management Platform provides actionable field data across real estate & facility portfolios to keep indoor spaces healthy, profitable, and sustainable.

Regular Performance Checks

Use the veriDART Portal to plan, execute, and manage ventilation and filtration with regular performance checks.

Dilution Tests (Room-Focused)

Optimize HVAC settings to clear high density areas of aerosols

Survey Tests (Zone-Focused)

Verify aerosol mobility and identify hotspots in ≤25,000 square foot zones

Recirculation Tests (HVAC-Focused)

Verify aerosol mobility to air handling units for improved outside air and filter management

Field Verification of Ventilation and Filtration in High Density Areas

Field verification leverages veriDART, the first diagnostic solution for verifying ventilation and filtration performance using patented aerosol tracing technology.

Aerosol tracers safely simulate pathogen mobility and exposure for performance verification and management of HVAC systems.
