What is an ULPA grade HEPA filter?
“ULPA grade HEPA filter” is a commonly used phrase when referring to ULPA filters. In reality, ULPA and HEPA are two different types of filters. They are identical in appearance but ULPA filters are capable of capturing particles much smaller in size, at an efficiency rate 10 times greater than HEPA filters. The generic name “ULPA” stands for “Ultra Low Penetration Air” filter. ULPA filters are tested and rated to remove particles .12 micron in size and larger, at an efficiency of 99.9995%. HEPA (High Efficiency Particulate Air) filters remove particles .3 micron and larger at an efficiency of 99.99%. ISOL-AIDE commercial products use ULPA filtration.
