When testing happens in the same building as production, problems are caught in hours, not weeks. It gives us full control over every filter we ship. And it lets us develop new products to current global standards, not outdated designs.

Yes. Prysm operates its own filter testing laboratory built to global benchmarks, so filters are verified before they ship rather than relying on outsourced quality checks.
Each Prysm HEPA filter is challenged with a test aerosol at the most penetrating particle size, with particles counted upstream and downstream to confirm efficiency. The full filter face is also scanned for leaks, following ISO 29463.
Prysm uses a full-scale ISO 16890 test rig that measures airflow resistance, fractional efficiency across particle sizes and dust holding capacity. These results determine each filter's ISO Coarse or ePM rating.
Yes. Customers can work with Prysm's in-house lab to validate filter performance, compare options or support product development; contact us to discuss the scope.
