Certifications & standards
Quality backed by independent certification.
Deltrian filters are tested and certified to European and international standards — the performance we quote is measured, not estimated.
ATEX certification
Certification for products intended to operate in potentially explosive atmospheres (gases or dust combined with air, electrical discharge or heat). It guarantees the filter runs safely in those conditions, which matters most in the pharmaceutical and food industries.
Learn moreISO 16890 certification
The international standard for rating air filter efficiency, introduced in 2018 to replace the old EN 779. It classifies filters by how well they capture particles of different sizes (ePM1, ePM2.5, ePM10, Coarse), tying filtration directly to air quality and health.
