SFFILTECH supplies EPA, HEPA, and ULPA filters for final-stage air filtration in compatible HVAC, cleanroom, FFU, and controlled-environment systems. Available formats include mini-pleat, box, compact, gel-seal, and knife-edge designs.

Selection should be based on the required efficiency class and applicable test standard, dimensions, rated airflow, initial and final pressure drop, frame depth, media, sealing arrangement, and required test documentation. System performance depends on correct installation and seal integrity; a filter should not be described as creating a sterile environment or preventing disease without application-specific validation.

For a staged system, begin with pre-filters and, where required, add pocket or compact filters before the final HEPA or ULPA stage.
