Methodology
How we measure.
01
Certified sensors
PM2.5, PM10, CO₂, temperature and humidity sampled every 30 seconds by certified sensors.
02
Digital signature and cloud
Every data point is digitally signed, timestamped and transmitted in real time to the Bufaga cloud. No post-collection interpolation.
03
Third-party audit
Datasets are available for verification by third-party certification bodies. Every impact report is structured for EU Green Claims compliance.
Certifications
Every claim has a certifying body.
ISO 14001
Bureau Veritas
Certifies the environmental management system and the accuracy of the integrated IoT sensors.
CE Marking
EU Conformity
Compliance with European directives on safety and electromagnetic compatibility.
Verifiable claims
Our environmental claims are verifiable.
Every figure we communicate — from the mass of particulate removed to the equivalents in kilometres or breaths — is calculated in real time by our device sensors, validated by independent laboratories and audited by a third-party verification body.

Frequently asked questions about environmental impact
How does Bufaga measure the environmental impact of its devices?
Every E-Bufaga device samples PM2.5, PM10, CO₂, temperature and humidity every 30 seconds with ISO 14001-certified sensors; data is digitally signed, timestamped and transmitted to the Bufaga cloud in real time, with no post-collection interpolation.
How much particulate matter does an E-Bufaga device remove on average?
Across the active fleet, each device removes over 200 grams of PM with a certified average efficiency of 90%, a certified average uptime of 99.4%, and a treated airflow above 1,200 m³/h per unit.
Is Bufaga's impact data compliant with the EU Green Claims directive?
Yes: every impact report is structured for compliance with the EU Green Claims Directive (2024/825), with third-party-verifiable data, documented methodology, and audit availability from independent certification bodies.
What certifications does the E-Bufaga technology hold?
The IoT sensors and environmental management system are ISO 14001-certified by Bureau Veritas; the devices carry CE marking for compliance with EU safety and electromagnetic compatibility directives.
