HEPA & ULPA Filters | 99.97% at 0.3μm for Cleanrooms

HEPA & ULPA Filtration

HEPA (High-Efficiency Particulate Air) filters are the highest-grade air filters available—required to capture at least 99.97% of particles as small as 0.3 microns. They're not standard HVAC filters; they're purpose-built for environments where the air has to be genuinely clean: hospitals, cleanrooms, pharmaceutical manufacturing, semiconductor fabrication, and nuclear facilities.

HEPA vs. MERV 13

A common question: why not just use MERV 13 everywhere? MERV 13 captures roughly 85% of particles down to 0.3 microns. HEPA captures 99.97%. For a home with good HVAC, MERV 13 is excellent. For a hospital operating room, pharmaceutical clean room, or semiconductor fab, MERV 13 isn't close to adequate—you need HEPA.

Typical Applications

• Healthcare — operating rooms, isolation rooms, pharmacy compounding areas
• Cleanrooms — ISO Class 5–8 environments
• Pharmaceutical & biotech — sterile fill-finish, research labs
• Semiconductor & electronics — fab environments where sub-micron particles destroy yield
• Nuclear & aerospace — radioactive particulate containment

ULPA Filters

ULPA (Ultra-Low Particulate Air) filters go further—99.999% efficiency at 0.12 microns. Used in ISO Class 1–4 cleanrooms and the most demanding sub-micron control environments.
