What Antrum does
Antrum is a Michigan-based private company that builds a centralized indoor air quality monitoring platform for commercial, institutional, and life-sciences buildings. Its core system, AntrumX, uses a patented air accelerator with no moving parts to pull air samples through tubing from multiple rooms into a single monitoring panel, replacing the dense network of wall-mounted sensors used in conventional demand-controlled ventilation with one sensor per roughly 16 spaces. A cloud-based dashboard, AntrumEYE, aggregates data from the centralized sensors and the building management system to deliver real-time visibility into air change rates, kWh savings, sash positions, and air quality trends. An exchangeable Sensor Pack, calibrated with NIST-traceable gases and swappable in under 60 seconds without tools, underpins the maintenance model.
The company's go-to-market is enterprise field sales targeting facility managers, university operations staff, EHS teams, and building owners, with a "Schedule a Demo" call-to-action as the primary conversion mechanism and a deep library of specification and BACnet integration documentation supporting the technical evaluation cycle. Revenue is generated primarily through AntrumX hardware sales, with a recurring component from replacement Sensor Packs priced at $1,444 USD each and a software layer (AntrumEYE) bundled with the hardware; implementation partners handle installation and BAS integration. Customer evidence spans U.S. higher education (Grand Valley State University across nine buildings, University of Illinois), life-sciences research (Carnegie Institution sites, a Canadian research institution vivarium), pharmaceutical R&D and sterile manufacturing (a New Jersey global pharma campus, a leading U.S. sterile injectable drug manufacturer), and a leading U.S. defense, aviation, IT, and biomedical research company deploying for California Title 24 compliance. Quantified customer outcomes include 10–30% building energy savings at GVSU, 40% ventilation-demand reduction at a sterile injectable drug manufacturer, 50% projected reduction in laboratory exhaust energy at a defense/aviation/biomedical site, and roughly 200 metric tons of CO2 savings projected annually at the R2 Carnegie Institution.
Antrum has raised capital via SEC Form D exempt securities offerings with a $5,000,000 total target (approximately $3,709,475 sold as of July 2025 and approximately $2.7M sold in an earlier December 2023 filing), holds two granted patents covering its centralized sensing architecture and air accelerator, won the 2022 AHR Expo Innovation Award in the Indoor Air Quality category, and maintains integration partnerships with Siemens and Antec building automation platforms. The company operates with 1–10 employees from its headquarters at 1300 Michigan St. NE, Grand Rapids.

Antrum product offering
Product offeringCore offering
Antrum provides real-time continuous indoor air quality monitoring solutions for buildings. The system combines centralized hardware sensors (AntrumX and its component Sensor Pack, Air Accelerator, Monitoring Panel, Faceplate, Duct Probe, and Gateway) with a cloud-based ventilation dashboard (AntrumEYE) to monitor air quality across facility environments. Target deployments include universities, healthcare facilities, life sciences labs, clean rooms, vivariums, and general-occupancy buildings.
Product overview
Antrum offers a centralized air monitoring platform consisting of AntrumX as the core hardware system and AntrumEYE as the cloud-based software dashboard. AntrumX uses a patented air accelerator (with no moving parts) to draw air samples from multiple zones through tubing to a central monitoring panel containing an exchangeable sensor pack, replacing traditional wall-mounted sensors (1 centralized sensor for every 16 wall-mounted sensors). The Gateway enables BACnet integration with building management systems. AntrumEYE provides the user interface for real-time monitoring, analytics, and energy savings reporting. The system is designed for easy maintenance with sensor packs that can be swapped in under 60 seconds without tools.

Antrum competitors and assessment
Company assessmentBroad incumbents
- Trane Technologies: Trane provides HVAC equipment, building controls, and air-quality solutions for commercial buildings. Its Trane Building Advantage and Symmetry systems overlap with Antrum's lab and university use cases but within a much broader HVAC portfolio.
- Siemens Smart Infrastructure: Siemens offers Desigo CC and building automation systems that include IAQ sensing and demand-controlled ventilation. Antrum already publishes a Siemens integration cutsheet, indicating direct co-deployment and overlap in target customer accounts.
- Honeywell Building Technologies: Honeywell's building automation division offers IAQ sensors, demand-controlled ventilation, and BMS integration at scale. It competes with Antrum in commercial and institutional buildings but as part of a much broader portfolio spanning security, energy, and HVAC controls.
- Johnson Controls: Johnson Controls' OpenBlue platform and Metasys BMS include IAQ monitoring, ventilation analytics, and lab-specific airflow control. It serves the same university, healthcare, and pharma verticals as Antrum but bundles IAQ with security, fire, and HVAC.
Direct peers
- Setra Systems: Setra manufactures IAQ sensors, room pressure monitors, and particle counters used in healthcare, labs, and pharmaceutical facilities. It is a direct competitor in the IAQ sensing niche, targeting the same compliance-driven buyer personas as Antrum.
- TSI Incorporated: TSI designs and manufactures precision air quality and particle measurement instruments for cleanrooms, labs, and industrial facilities. It overlaps with Antrum on the cleanroom and laboratory IAQ monitoring use case, particularly where ISO 14644 compliance is required.
- Bacharach (UE Systems): Bacharach supplies commercial-grade indoor air quality monitors, refrigerant leak detectors, and combustion analyzers for HVAC and facilities applications. It targets a similar facilities-management buyer with portable and fixed IAQ instrumentation.
Emerging players
- Aclima: Aclima provides hyperlocal air quality sensing and analytics, with growing presence in commercial buildings and indoor environments. It is an emerging player with overlapping IAQ-as-a-service ambitions but is more focused on outdoor/indoor mapping than Antrum's lab ventilation control niche.
- Aeroqual: Aeroqual makes air quality monitors and sensor modules for industrial, commercial, and outdoor applications. It overlaps with Antrum on multi-parameter IAQ sensing but is more diversified across portable and outdoor use cases.
- Senseware: Senseware offers a wireless building sensor platform covering IAQ, energy, and occupancy with plug-and-play installation. It targets similar building-decisioning use cases as AntrumEYE but with a different (distributed wireless) sensing architecture.
