What is deployed today.
Continuous indoor air risk measurement, turned into evidence an institution can defend.
AirShield is the part of the system that is operational now. It runs in real buildings, it produces the data the laboratory iterates on, and it is the reason Sentinel is being developed against real air rather than test air.
How it works
Measure, interpret, act.
01Measure
Continuous multi-zone sampling of biological and environmental signals across critical areas. No spot checks, no annual snapshots: a permanent, defensible baseline.
Operating blocks, ICU corridors, isolation rooms, sterile storage — every zone that carries risk carries a continuous signal.
02Interpret
Analytics turn raw signals into risk positions: which zone, what severity, which trend, and what it means against an accreditation criterion.
Interpretation is validated against accredited laboratory methods, not against thresholds we set ourselves.
03Act
Decision-ready evidence: prioritised interventions, verified outcomes, and documentation that survives an audit.
Every action closes with an evidence pack. Governance means being able to show your work.
The science inside
Nothing in AirShield rests on our own word.
Every analytical method in AirShield is validated with accredited reference institutions, developed under competitive public funding, and protected by a filed patent. The full record is public and verifiable.
Accredited validation
Analytical methods validated with ULB CREST, the Belgian reference laboratory for indoor air quality.
Public-science backbone
Developed within EU and regional research programs, alongside Sciensano, VITO, and IssEP.
Protected method
The AirShield system is covered by a patent filed Q1 2026 via Calysta.
Regulatory alignment
Built to the biological IAQ criteria now forming in the European regulatory debate.
Field data
Why this matters for Sentinel
A detection platform is only as good as the environments it has survived. AirShield deployments give the laboratory continuous measurement from real critical zones on three continents — the messy, drifting, occupied air that a bench cannot reproduce. Sentinel is being developed against that, not against a clean-room simulation of it.
Results under clinical review.
The first case study, from the UZ Brussel deployment, is in progress. We publish results in one format only: full name, exact title, service, institution, and a measured outcome. Nothing vaguer than that is worth your reading time.
