Performance Attributes
High Capacity Performance & Certified Integrity
-
Increased Pleat Count — Maximum Media Area: HC HEPA has higher pleat count within the deep-pleat construction than the SC HEPA Filter, raising rated airflow from 1200 CFM to 1700 CFM at the same 1.10 in wc initial pressure drop. More pleats packed into the same filter depth directly increases effective media surface area, reducing face velocity at equivalent airflow and dramatically extending the service interval before the recommended final pressure drop of 2.00” wg is reached — minimising change-out frequency in high-demand continuous operations.
-
Individual Testing per EN 1822: Every filter unit is tested across its entire face using an aerosol photometer or particle counter to verify the absence of localised leaks in the media pack, frame seal, and gasket interface. Test results are documented and affixed to each unit — providing the traceable per-unit certification required for pharmaceutical GMP batch records, hospital validation, and ISO cleanroom commissioning.
-
Corrugated Aluminum Separators with Hemmed Edges: Precision-formed hemmed edges evenly and precisely position the pleated media pack, preventing separator migration and pleat convergence throughout the filter's service life. Uniform pleat spacing maintains consistent airflow distribution and preserves the maximum effective media area from first installation to end of service.

Selection Guide
How to Select the Right High Capacity HEPA Filter for Your Application
-
1
Identify your EN 1822 grade requirement
Select E12 (≥99.5% MPPS) for general industrial pre-filtration and light cleanroom applications. Select H13 (≥99.95% MPPS) for hospitals, pharmaceutical manufacturing, and ISO Class 5–7 cleanrooms. Select H14 (≥99.995% MPPS) for ISO Class 3–4 cleanrooms, aseptic environments, and critical containment applications demanding the highest certified sub-micron particle removal.
-
2
Confirm whether High Capacity or Standard Capacity is required
Choose the High Capacity design when minimising change-out frequency is a primary operating requirement, when airflow volumes are high (HC is rated to 1700 CFM vs 1200 CFM for SC) and the largest possible media area is needed within the available housing depth, or when extended service intervals between planned maintenance shutdowns are specified. Both designs share the same EN 1822 grade range and external housing dimensions.
-
3
Select the frame material
Choose GI for standard industrial and commercial applications. Select SS for pharmaceutical, food processing, and corrosive environments. Choose AL for weight-sensitive ceiling grid or module installations. Specify MDF where non-metal construction is required by the facility or housing design.
-
4
Select the gasket type and verify installation parameters
Choose seamless polyurethane (PU) gasket for most cleanroom and HVAC applications. Select Neoprene where chemical resistance or specific compression characteristics are required by the housing specification. Confirm operating temperature does not exceed 80°C (176°F) and that the system supports the 2.00” wg recommended final pressure drop.
Product Comparison
Performance Comparison: Deep Pleat SC and HC HEPA vs. V-Bank HV HEPA
The HEPA HV Filter is the top-performing model in the AccuraFil range, utilizing a V-Bank mini-pleat design to provide the highest media surface area (291 sq.ft.). This allows it to handle 2000 CFM while maintaining the lowest resistance (1.05 in wc), offering superior airflow and energy efficiency compared to traditional deep-pleat designs.
In contrast, the HC HEPA and SC HEPA filters use deep-pleat designs. The HC supports 1700 CFM and the SC supports 1200 CFM — both at a 1.10 in wc initial pressure drop. All three models are available in the same EN 1822 grade range (E12, H13, H14); the choice depends on housing depth, target airflow, and energy efficiency priorities.
Frequently Asked Questions
Product FAQ
What is the difference between a High Capacity HEPA filter and a Standard Capacity HEPA filter?
The High Capacity (HC) and Standard Capacity (SC) HEPA filters share identical dimensions and deep-pleat construction, differing only in pleat density. By packing more media into the same footprint, the HC model increases surface area, leading to greater dust-holding capacity and a longer service life. This design boosts rated airflow to 1,700 CFM (compared to 1,200 CFM for the SC HEPA filter) while maintaining the same 1.1” w.c. initial pressure drop.
What EN 1822 grades are available and what do they mean?
EN 1822 is the European standard for HEPA and ULPA filters, using Most Penetrating Particle Size (MPPS) efficiency as the defining metric. AccuraFil's High Capacity HEPA Filter is available in three grades: E12 achieves ≥99.5% MPPS efficiency and suits general industrial and light cleanroom pre-filtration; H13 at ≥99.95% MPPS is the primary grade for hospitals, pharmaceutical manufacturing, and ISO Class 5–7 cleanrooms; H14 at ≥99.995% MPPS is required for ISO Class 3–4 cleanrooms, aseptic filling environments, and critical containment applications where the highest sub-micron particle removal is mandatory.
What is MPPS efficiency and why does EN 1822 use it instead of fixed 0.3-micron efficiency?
MPPS — Most Penetrating Particle Size — is the particle size at which a given filter media achieves its lowest efficiency. For glass microfiber HEPA media, MPPS typically falls in the 0.1–0.3 micron range depending on fiber diameter and media structure. EN 1822 rates filters at MPPS because it represents the worst-case filtration scenario: a filter that meets its rated efficiency at MPPS will exceed that efficiency at all other particle sizes. This makes MPPS efficiency a more rigorous and conservative metric than a single fixed-particle-size result. AccuraFil also provides efficiency at 0.3 microns for cross-reference with ASHRAE and legacy specifications.
What does individually tested per EN 1822 mean and why is it required?
Individual testing per EN 1822 means every filter unit is tested across its entire face — not batch sampled — using an aerosol photometer or particle counter to confirm the absence of localised leaks in the media pack, frame seal, and gasket interface. Test results are documented and affixed to each filter, providing per-unit traceability for regulatory audits, pharmaceutical GMP batch records, cleanroom validation protocols, and hospital commissioning documentation. For critical environments, individual per-unit test certification is typically a mandatory procurement requirement that batch-tested filters cannot satisfy.
What frame and gasket options are available?
The AccuraFil High Capacity HEPA Filter is available with frames in GI (standard galvanized steel for general applications), SS (stainless steel for pharmaceutical, food processing, and corrosive environments), AL (aluminum for weight-sensitive installations), and MDF (where non-metal construction is specified). Gasket options are seamless polyurethane or Neoprene, selected based on housing face seal requirements, chemical exposure, and temperature range. The two-part polyurethane media sealant provides a permanent, leak-proof bond between the media pack and frame throughout the filter's service life.
How does the AccuraFil HC HEPA compare to the V-Bank HV HEPA?
The AccuraFil V-Bank HV HEPA uses a mini-pleat V-bank design providing 291 sq ft of media area and handles up to 2000 CFM at 1.05 in wc — the highest-airflow HEPA model in the AccuraFil range. The HC HEPA uses a deep-pleat design supporting 1700 CFM at 1.10 in wc. The SC HEPA supports 1200 CFM at the same 1.10 in wc initial pressure drop. All three carry the same EN 1822 grade options (E12, H13, H14).
