What is the difference between HEPA and ULPA filters?

HEPA filters are rated to capture 99.97% of particles as small as 0.3 microns. ULPA (Ultra-Low Penetration Air) filters provide an even higher level of filtration, capturing 99.999% of particles at 0.1 microns, typically used in high-precision cleanrooms.

In which environments are HEPA & ULPA air filter services required?

These filters are essential for critical environments including hospital surgical suites, airborne infection isolation rooms (AIIR), pharmaceutical compounding labs, and semiconductor manufacturing cleanrooms.

Does ATL Filtration provide performance certification for these filters?

Yes. Our air filter services include providing technical data for individually tested and certified HEPA/ULPA filters to ensure they meet the specific leak-test and efficiency requirements of your facility's regulations.
