Case Studies

When PPI rating matters

Medical Devices

CPAP intake filter service life

ProblemExisting single-layer filter loaded too quickly — 30-day replacement cycle was hurting brand NPS and driving subscription churn.
SolutionGraduated 30/60 PPI dual-layer reticulated PU with charcoal-impregnated middle layer. Die-cut to OEM housing, foil-sealed edge to prevent bypass.
MaterialsReticulated PU 30/60 PPI · charcoal-impregnated layer · PSA edge seal
✓3× service life · spec passed
Industrial Computing

Server cooling intake pre-filter

ProblemIndustrial-floor server deployment seeing dust loading on processor heatsinks, requiring monthly HVAC-team cleaning visits.
Solution45 PPI reticulated PU pre-filter with antimicrobial surface treatment, die-cut to fan housing geometry. Customer-replaceable on a 6-month cycle.
MaterialsReticulated PU 45 PPI · antimicrobial coating · tab-pull design
✓Heatsink dust −90% · zero downtime
