Restart, Reunite with Antrum

The quality of your restart — measured in ppm.

Know Your Air

AntrumX™ is a patented Indoor Air Quality (IAQ) monitoring technology that provides your Building Management System and facilities personnel with the real-time data needed to ensure the healthiest air quality possible for your students and faculty—all while optimizing ventilation for increased energy savings.

The COVID-19 pandemic has drawn the world’s attention to indoor air quality. Recent studies consistently rank indoor air pollution among the top five environmental risks to public health. When it comes to schools, the EPA is explicit: “Good IAQ is an important component of a healthy indoor environment, and can help schools reach their primary goal of educating children.”

  • Indoor pollutant levels may be 2 to 5 times higher than outdoor levels—and occasionally more than 100 times higher. This is concerning because on average most people spend 90 percent of their time indoors.
  • Nearly 1 in 13 school-age children has asthma. Asthma is the leading cause of school absenteeism due to chronic illness. There is substantial evidence that indoor environmental exposure to allergens plays a role in triggering asthma symptoms.

To ensure the best air quality for all of your occupants, you have to know what’s in your air.

Introducing AntrumX.

How it Works

AntrumX centralizes sensors in a patented sensor pack, allowing multiple IAQ parameters to be measured simultaneously from a single location. AntrumX continuously draws air samples from up to 32 unique faceplates/spaces to the sensor pack in the monitoring panel, where it measures and reports data to the BMS and the cloud for further analysis.


Supplying the necessary volume of outdoor air to maintain appropriate CO2 concentration is essential to the overall health of your building. Additionally, optimized ventilation dilutes the concentration of airborne contaminants, improves occupant comfort and efficiency, and decreases energy usage and cost.


VOCs include a variety of chemicals emitted by a wide array of everyday products, i.e. paint, disinfectants, clothing, building materials, and office equipment. Supplying adequate outdoor air and maintaining appropriate ventilation are critical to reducing VOC exposure inside commercial buildings.


Environments with higher moisture content are susceptible to mold growth. Adversely, studies have begun showing a connection between drier indoor climates and increase virus “float” and survival time. There is growing scientific evidence regarding the significant benefits a mid-range air humidity has on human health. Understanding and managing RH has never been more essential to the health of your building and its occupants.


Particulate matter (PM) is the term representing the sum of all solid and liquid particles suspended in air, many of which are hazardous. Besides the potential harmful effects PM can have on the environment, exposure to these dangerous microscopic solids and liquids can adversely affect human health, with fine particles (PM2.5) being the most dangerous. Supplying adequate outdoor air and maintaining appropriate ventilation are critical to reducing exposure to harmful PM inside commercial buildings.

A Study in Innovation

Engineers at Grand Valley State University developed the technology behind AntrumX for over a decade. In that time, it has monitored the IAQ of nearly 900 rooms and 600,000 square feet of educational space, creating demonstrably healthier learning environments for GVSU students and resulting in significant savings, both in energy usage and in installation/maintenance costs.
