Transparency on impact measurement.
Every Bufaga environmental statement has proof. Here you find the technology, the calculation methodology and the independent verification documents that support it.
Verifiable statements
Every figure we communicate — from the mass of particulate removed to the equivalent kilometres or breaths — is calculated in real time by our device sensors, validated by independent laboratories and audited by a third-party verification body.
01
Technology
The sensors that measure every gram.
The device integrates Sensirion sensors for continuous measurement of particulate concentration and a differential pressure sensor in the filtering system. Data is acquired up to every second and associated with a timestamp, device ID and ambient parameters at the time of detection. This granularity enables accurate calculation of removed mass in real time.
02
Methodology
How we calculate impact data.
Removed mass is derived from the difference between incoming and outgoing particulate concentration, the latter correlated with the treated flow rate. The flow rate is determined by the actual equilibrium point between available ventilation and filter resistance. Published values apply a conservative uncertainty margin to ensure no statement is overstated.
03
Supporting evidence
The laboratory reports.
Performance tests (ref. UNI EN ISO 14644): Tests were conducted by S.T.S. – Servizi Tecnici e Sanitari at 21 sampling points. Result: PM10 reduction of up to 93% near the device after 90 minutes of continuous operation. Sensor validation: Integrated sensors were validated against reference instrumentation by an accredited supplier collaborating with institutions on air quality monitoring. Correlation found: R² = 0.999 on an hourly and daily basis for PM2.5; R² = 0.998 for PM10; R² = 0.997 for PM1.
04
Verification bodies
Who certifies our data.
The entire green claims management system — calculation methodology, data traceability, statement formulation — has been audited by an independent verification body, guaranteeing compliance with the European Anti-Greenwashing Directive and ISO 14021. The complete documentation (raw data, calculation parameters, test reports) is archived and available on request for external verification.
