Applications
HEPA panel filters of this type are used in clean room air handling systems, laminar flow hoods, fan filter units (FFUs), and HVAC installations where high-efficiency particulate removal is required. The 99.99% efficiency rating at 0.3 microns meets the HEPA standard and is suitable for semiconductor fabrication, pharmaceutical manufacturing, life sciences labs, and other controlled-environment applications that require removal of fine particulates, aerosols, and airborne contaminants. The triangular profile on this filter suggests it is designed for a specific equipment enclosure or angled ceiling/wall installation where a standard rectangular filter would not fit — a common design in modular clean room ceiling systems and certain industrial air handlers. Buyers typically source replacement filters like this for ongoing maintenance of existing clean room infrastructure.
This Halco H2237A00-AAABABA HEPA air filter has been inspected and is in good used condition. The aluminum frame is intact and shows only minor surface wear. The pleated HEPA media appears intact with no visible tears, punctures, or major contamination on either face. Some light yellowing is visible on the upstream face of the filter media, consistent with prior service use. The rear black media and gold separator fins appear in good shape with no obvious damage.

Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
