Ultra-low particulate air
For the model law, see Uniform Limited Partnership Act.
ULPA is an acronym for "Ultra Low Penetration Air (filter)" An ULPA filter can remove from the air at least 99.999% of dust, pollen, mold, bacteria and any airborne particles with a size of 100 nanometres (0.1 µm) or larger.
A number of recommended practices have been written on testing these filters, including:[1]
- IEST-RP-CC001: HEPA and ULPA Filters,
- IEST-RP-CC007: Testing ULPA Filters,
- IEST-RP-CC022: Testing HEPA and ULPA Filter Media, and
- IEST-RP-CC034: HEPA and ULPA Filter Leak Tests.
