Ventilation & IAQ Solutions
working together to make buildings healthier, more energy efficient & sustainable
“Airborne transmission of all infectious aerosols (including SARS-CoV-2) is significant and should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning systems, can reduce airborne exposures.”
Without people, there’s no need for buildings. Let’s provide a high standard of care for people inside all buildings, as well as making the buildings efficient and sustainable.
Improve IAQ & Control Infectious Aerosols + Reduce Energy Use & Carbon
Clean the Indoor Air First
“It is the responsibility of building owners & businesses to insure IAQ in their indoor spaces and to reduce the risk of disease transmission.“
– National Strategy for Improving Indoor Air Quality – Johns Hopkins Center for Health Security –
ASHRAE Standard 241 establishes minimum requirements for controlling infectious aerosols and reducing the risk of disease transmission in new and existing buildings. Included are requirements for both outdoor air system and air cleaning system design, installation, commissioning, operation, and maintenance to reduce exposure to infectious aerosols.
Improving ventilation measurement, verification & performance
ACH to eACH to ECAi
from Air Changes/Hour to Equivalent Air Changes/Hour to Equivalent Clean Air Flow/Person
Current minimum ventilation requirements in ASHRAE Standard 62.1 are not sufficient for infectious aerosol mitigation. Providing higher clean air rates as required in the new ASHRAE Standard 241-2023 can significantly contribute to creating safer and healthier indoor spaces. ACH (air changes/hour) is a measure of airflow relative to the room volume, it does not take into account occupancy. It is not a meaningful value when assessing the concentration of pollutants. The new metric ECAi (equivalent clean air flow/person) takes into account occupancy, room volume and the concentration of pollutants.
May 16, 2023 | CDC: Aim for 5 ACH/hour in Buildings. The Centers for Disease Control and Prevention (CDC) updated its “Ventilation in Buildings” guidelines to include a discussion on “How much ventilation is enough?” to help prevent airborne disease transmission (5 ACH).

Right size to your building’s true occupancy for energy savings, sustainability & occupant health 
The world’s first real-time indoor air particle tracing system. Poppy’s particle-and-sensor system mimics human breath. It instantly measures the equivalent clean indoor airflow of all natural and mechanical ventilation, air purifiers and filtration. Professional-grade accuracy by means of the tracer aerosol decay method specified in ASHRAE Standard 241-2023.

Delivers Infection Control to Everyday Workspaces & Educational Buildings
Combines high-capacity airflow, ultraviolet germicidal irradiation (UVGI), true HEPA filtration and activated carbon to remove dangerous airborne particles and disable pathogens as quickly as every 5 minutes.
450 CFM, 1200 CFM & 1500 CFM Models 6-12 equivalent eACH
Adds Equivalent Clean Airflow (ECAi) without increasing the OA
Airborne transmission is the primary route of viruses & other pathogens. Improving the Equivalent Clean Air Flow/Person (ECAi) in occupied spaces is a bigger determinant in controlling infectious aerosols, than increasing Outside Air via the HVAC system!
Healthy Buildings Start with Far-UVC.
Introducing Visium™, the revolutionary solution from Lit Thinking™ that utilizes human-safe light to inactivate up to 99.9 percent of airborne viruses and bacteria silently and continuously. With Visium™, the future of healthy buildings has arrived.
Visium™ is the first UL certified, continuous sanitization device of its kind, and its efficacy has been rigorously tested and validated. UL 2998 Zero Ozone Emissions Certified.
