TU Berlin / HRI confirms more homogeneous air purification for the dp concept in independent airflow analysis
The Hermann-Rietschel-Institut (TU Berlin) short study compared two ceiling-mounted dp Purifier Lamps with one mobile floor-standing purifier in a simulated 60 m² classroom at 760 and 1,000 m³/h recirculation airflow — finding more homogeneous air purification in the occupied zone and a higher average purification level at breathing height for the dp concept.

Client References
Trusted by institutions across the world
Formal reference letters from organisations that have installed and operated the dp Purifier Lamp — from Europe's largest rail operator to internationally certified German schools.
These letters represent unsolicited, signed endorsements from facility managers, school administrators and technical directors — confirming real-world results in offices, meeting rooms, kindergartens and classrooms after deploying the dp Purifier Lamp ceiling system.
Key themes emerging across all references: noticeably improved air quality, seamless ceiling integration, app-based control, elegant design, and a room climate perceived as more pleasant. Individual feedback from the kindergarten also describes a subjective impression that children appear to fall ill slightly less frequently — these are personal observations by the teaching staff, not a medical study.
