Performance Attributes
Deep-Pleat Performance & Certified Integrity
-
Individual Scan Testing per EN 1822: Every filter is tested across its entire face using an aerosol photometer or particle counter to verify the absence of localised leaks in the media, frame seal, and gasket interface. Test results are documented and affixed to each unit — providing the traceable certification required for pharmaceutical GMP, hospital validation, and ISO cleanroom commissioning. This is the most rigorous form of HEPA certification: every unit, not a batch sample.
-
Deep-Pleat Large Filter Area: The deep pleat construction maximises effective media surface area within the filter depth, reducing face velocity and enabling high volumetric airflow at 1200 CFM and 1.10 in wc initial pressure drop — making it suited to high-capacity AHUs and recirculation systems with demanding airflow requirements.
-
Corrugated Aluminum Separators with Hemmed Edges: Precision-formed hemmed edges prevent separator migration and pleat convergence across the deep media pack, maintaining uniform airflow distribution and protecting the glass fiber media from damage throughout the filter's service life.

Selection Guide
How to Select the Right Standard 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 individual scan test certification requirements
For pharmaceutical GMP, hospital infection control, and cleanroom qualification, verify that individual scan testing per EN 1822 is required by your facility's validation protocol or procurement specification. AccuraFil Standard Capacity HEPA Filters are individually scan tested as standard, with test results labeled and affixed to each unit for full traceability.
-
3
Select the frame material
Choose GI (standard galvanized steel) for general 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 volume, and energy efficiency priorities.
Frequently Asked Questions
Product FAQ
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 Standard Capacity HEPA Filter is available in three grades: E12 achieves 99.5% MPPS efficiency and is suited to 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 is it used instead of 0.3 micron efficiency for HEPA filters?
MPPS — Most Penetrating Particle Size — is the particle size at which a given filter media achieves its lowest efficiency. For glass fiber 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: if a filter meets its rated efficiency at MPPS, it will exceed that efficiency at all other particle sizes. MPPS efficiency is therefore a more rigorous and meaningful metric than fixed-particle-size efficiency alone. AccuraFil also provides efficiency at 0.3 microns for cross-reference with ASHRAE and legacy specifications.
What is individual scan testing per EN 1822 and why does it matter?
Individual scan testing per EN 1822 means every filter unit is tested across its entire face using an aerosol photometer or particle counter to verify that no localised leaks or pinholes exist in the media, frame seal, or gasket interface — not just statistically sampled from a production batch. Test results are documented and affixed to each filter unit, providing traceable proof of performance for regulatory audits, cleanroom qualification records, and commissioning documentation. For pharmaceutical, healthcare, and critical containment applications, individual scan test certification is typically a mandatory procurement requirement.
What is the difference between the Standard Capacity and High Capacity HEPA filter?
Both SC and HC HEPA filters share identical external dimensions and deep-pleat construction, differing only in pleat density. The HC model packs more media into the same footprint, increasing surface area and rated airflow to 1700 CFM versus 1200 CFM for the SC, while maintaining the same 1.10 in wc initial pressure drop. Choose HC where minimising change-out frequency is the primary requirement; choose SC for standard deep-pleat HEPA applications.
What frame and gasket options are available?
The AccuraFil Standard Capacity HEPA Filter is available with frames in GI (standard galvanized steel), SS (stainless steel for corrosive or pharmaceutical 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.
