Balancing the invisible.

Very few things are more dynamic than the indoor air we breathe. Each room, even parts of rooms, vary due to occupancy, season, ventilation settings—even the time of day.

  • Some areas are over-ventilated and use more energy than needed to heat, cool and circulate clean air

  • Some areas are under-ventilated and put occupants at risk of getting sick

Balance can be achieved by:

  • Natural or mechanical means (think open windows vs. HVAC settings)

  • Diluting, filtering and purifying the air (especially HEPA & MERV-13)

  • Adjusting how an area is used and by how many (a busy gym vs. quiet office)

It's hard to improve what you don't measure, so Poppy accurately measures ventilation performance.

What you get.

How it works.

The world leader in clean airflow monitoring, Poppy's tracer particle system measures all natural and mechanical ventilation-dilution, filtration and purification with one accurate, real-time test.

After releasing safe, food-grade tracer particles into the air, Poppy sensors collect millions of data points tracking how particles move and are removed over time. Within minutes, results and recommendations are available in a secure online dashboard.​

Poppy system includes:

  • Sensor accuracy with 10% of ISO 21501 calibrated reference particle counters in all size ranges (E1, E2, E3) - mandatory for ASHRAE Standard 241 tests

  • Particle counts within 7 submicron and supramicron size bins ranging from PC0.1 to PC10

  • Food-safe tracer particle (salt & water) diffusion at known sizes

  • 3D Digital Twin capture and volumetric measurement using LiDAR

  • Automated machine learning/AI data analysis algorithm and recommendations

  • Secure Online Dashboard & Testing App, SMS or Email Alerts

  • Secure IoT wireless connected system (USB, WiFi LAN WAP/2.4gz 802.11n)

  • Building Management and Building Automation System (BMS/BAS) integrations and APIs

What Poppy monitors.

Poppy monitors the broadest range of accurate airflow and air quality measurements in a compact, affordable tracer sensor system.

  • Equivalent Clean Airflow Rate (ECAi, VECAi)

  • Effective Air Change Rate (eACH)

  • Airflow Pathways and Patterns

  • Safe Occupancy Levels

  • Wildfire Smoke Clearance Rate

  • Cigarette Smoke & Vape Events

  • Indoor Air Quality (IAQ) & Air Quality Index (AQI)

  • Temperature & Humidity

  • Volatile Organic Compounds (TVOCs)

  • Carbon Dioxide (eCO2)

  • Particle Counts, ultrafine, fine, coarse (PC0.1-PC10)

  • Particle Mass, ultrafine, fine, coarse size (PM0.1-PM10)

Data-Driven Decisions.

Poppy's system automatically generates recommendations based on your latest results - either for humans to review, or integrated into your building management system (BMS/BAS) to trigger the best HVAC run-mode automatically.


Accurate, instant data alone doesn't move the needle, so Poppy provides hands-off energy savings. Now that moves the needle. 

The new standard.

Released in July 2023, ASHRAE, the American Society of Heating Refrigerating and Air-Conditioning Engineers released Standard 241, the new indoor air quality standard for control of infectious aerosols in buildings. With testing protocols outlined in Appendix C, Poppy provides the only digital method to test for Standard 241.
