FPI’s air quality monitoring systems have achieved full US EPA certification, marking a significant milestone in global environmental governance.
As regulatory standards continue to tighten worldwide, greater emphasis is being placed on data consistency, system stability, and adaptability across diverse environmental conditions.
In response, FPI has developed a comprehensive air quality monitoring solution covering both particulate matter and gaseous pollutants, delivering reliable data aligned with international standards for global users.
FPI’s AQMS portfolio has achieved full certification by the United States Environmental Protection Agency (US EPA), demonstrating compliance with stringent performance and long-term consistency requirements.
The PM₂.₅ particulate matter analyzer has been officially listed in the Federal Register under certification number EQPM-0325-269.
As a key part of the certification process, the instrument underwent 15 months of field testing across multiple U.S. states, including California, Connecticut, Michigan, and Idaho, completing five rounds of equivalency and gravimetric comparisons. Across different seasons and environmental conditions, the FPI PM₂.₅ analyzer consistently demonstrated stable performance, validating its long-term consistency in complex environments.
Bakersfield, California – February 10, 2023 to March 10, 2023

Michigan – Dearn, January 15, 2024 to February 15, 2024
Idaho – Boise, March 20, 2024 to April 25, 2024
The certification was conducted independently by an EPA-authorized third-party organization, with testing spanning multiple regions and climate conditions, and without any manufacturer intervention. In parallel, FPI conducts rigorous pre-delivery stability verification in accordance with US EPA standards, ensuring plug-and-play readiness and immediate measurement accuracy upon deployment.
To date, FPI’s AQMS systems have been deployed in over 20 countries and regions, with more than 33,000 units delivered. Following the certification announcement, multiple international partners have initiated further collaboration and procurement discussions, accelerating global adoption.
Beyond certification, long-term performance in real-world environments remains the ultimate measure of instrument value.
In a national-level meteorological system upgrade project, FPI’s self-developed PM₂.₅ and PM₁₀ analyzers have been successfully deployed in critical monitoring applications, demonstrating performance and reliability comparable to leading international products.
Through algorithm optimization and system-level integration, the solution delivers enhanced operational stability, reduced maintenance frequency, and improved data continuity. Deployed across complex environments—including high-altitude regions, coastal areas, and deserts—the instruments maintain stable performance under extreme conditions such as high humidity and heavy dust.
User feedback indicates reliable operation and ease of maintenance, significantly improving data continuity and credibility.
Building on continuous field validation, FPI is advancing intelligent upgrades in both algorithms and system design to further enhance autonomous operation in complex environments, with plans for broader deployment across monitoring networks.
From standard-based validation to real-world deployment, FPI continues to strengthen its overall capabilities in air quality monitoring systems.
Looking ahead, FPI will continue to drive innovation guided by international standards, advancing the global deployment of its air quality monitoring solutions.
