Electrostatic Discharge (ESD) and 16890 Efficiency Test Without ESD
Synthetic filter media often relies on an electrostatic charge to reach the efficiency printed on its label. That charge fades in service. ISO 16890 deals with this by testing the filter again after the charge has been removed, and the discharged result is the number worth trusting. Below is where the charge comes from, why…

EN1822 Standard – High Efficiency air filters (HEPA and ULPA)
EN 1822 classifies EPA, HEPA and ULPA filters by their efficiency at the most penetrating particle size (MPPS). Part 1 of the standard, EN 1822-1:2019, carries the classification table: eight classes from E10 to U17. An H13 filter has to reach 99.95% integral efficiency at MPPS, an H14 filter 99.995%. Below is the full table,…
