Choosing the Right EN 1822 HEPA Grade
Select the appropriate HEPA efficiency grade based on the required particulate removal performance, cleanroom classification, HVAC system design, and applicable facility requirements.
E12 HEPA Filter
99.5% MPPS efficiency. Suitable for general industrial applications and selected cleanroom pre-filtration requirements.
H13 HEPA Filter
99.95% MPPS efficiency. Designed for demanding applications including hospitals, pharmaceutical manufacturing, and controlled cleanroom environments.
H14 HEPA Filter
99.995% MPPS efficiency. Intended for applications requiring very high-efficiency particulate filtration, including critical cleanroom and aseptic environments.
Standard Capacity HEPA vs. High Capacity HEPA
The Standard Capacity (SC) HEPA uses a deep-pleat construction designed for dependable high-efficiency filtration across commercial and industrial HVAC applications. The High Capacity (HC) design uses a higher pleat count within the deep-pleat construction to provide more effective media area within the same external footprint.
The SC design is rated for 1200 CFM at an initial pressure drop of 1.10 in. w.c., while the HC design is rated for 1700 CFM at the same initial pressure drop. The appropriate design should be selected based on airflow requirements, filter service expectations, housing configuration, and maintenance priorities.
HEPA Filter Construction & Sealing
Glass Fine Microfiber Media
Glass fine microfiber media provides the filtration medium for high-efficiency HEPA applications requiring E12, H13, or H14 performance.
Corrugated Aluminum Separators
Hemmed-edge corrugated aluminum separators help maintain consistent pleat spacing and airflow distribution through the deep-pleated media pack.
Polyurethane Media Sealant
Two-part polyurethane sealant provides a durable bond between the media pack and frame.
PU & Neoprene Gasket Options
Seamless polyurethane and Neoprene gasket options are available according to the required housing sealing configuration.
HEPA Filter Frame Designs: Double-Turn Flange vs. Box-No-Header
HEPA filters are available with different frame and header designs to match the existing filter housing or holding frame. Choosing the correct frame style is important for proper installation, sealing, filter support, and maintenance access. Always match the replacement HEPA filter to the existing housing design rather than selecting a frame based only on nominal filter size.
Important:
Frame design is not interchangeable simply because the nominal filter size
is the same. Before ordering a replacement HEPA filter, verify the existing
housing's frame style, flange/header design, actual filter dimensions,
gasket or sealing arrangement, and installation orientation. Selecting the
wrong frame design can cause installation problems, inadequate sealing,
return shipping costs, restocking charges, and project delays.
⚠️ Important: Verify Actual HEPA Filter Dimensions Before Ordering
HEPA filters must be ordered and matched by their actual dimensions, not nominal dimensions. Incorrect measurements can result in installation misfit, return shipping fees, restocking charges, and project delays.
Nominal Size
24" × 24" × 12"
Actual Dimensions
23 3/8" × 23 3/8" × 11 1/2"
Before placing your order: Verify the actual width, height, and depth of your existing HEPA filter and confirm compatibility with your filter housing. This simple step can help prevent misfit issues, unnecessary return shipping costs, restocking charges, and installation delays.

Reliable Performance in High-Demand Environments
The deep-pleated Standard Capacity HEPA design provides a large effective filtration area for demanding HVAC applications where high-efficiency particulate removal, reliable airflow, and individually tested filter performance are important operating requirements.
Pharmaceutical & Biotech Manufacturing
H13 and H14 configurations are suited to pharmaceutical, biotechnology, GMP manufacturing, aseptic processing, and controlled cleanroom environments requiring individually scan tested HEPA filtration.
Hospitals & Healthcare
H13 and H14 configurations support demanding healthcare HVAC applications including operating theatres, isolation areas, critical care spaces, and other environments requiring high-efficiency particulate filtration.
ISO Cleanrooms
High-efficiency HEPA filtration is suitable for controlled environments where documented filter testing, validated particulate removal, and reliable air-handling performance are required.
Industrial & Commercial AHUs
E12 through H13 configurations support demanding industrial and commercial air-handling applications where deep-pleat HEPA filtration, reliable airflow, and serviceable filter construction are required.
Individually Scan Tested Per EN 1822
Every AccuraFil Standard Capacity HEPA filter is individually scan tested according to EN 1822 rather than relying solely on batch or statistical sampling. Testing evaluates the finished filter across its face to identify potential leaks or integrity issues.
Test results are documented and affixed to each filter, providing unit-level traceability for procurement, commissioning, validation, and controlled-environment documentation.
MPPS Efficiency and EN 1822 Classification
EN 1822 classifies high-efficiency filters using Most Penetrating Particle Size (MPPS) efficiency. The AccuraFil Standard Capacity HEPA product family is available in E12, H13, and H14 grades with progressively higher certified MPPS efficiency.
Efficiency values at 0.3 µm are also provided for reference when comparing HEPA filtration requirements with specifications that use fixed-particle-size efficiency.
Standard Capacity HEPA vs. V-Bank 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.
The best HEPA filter selection depends on the required EN 1822 grade, airflow, initial and final pressure drop, filter dimensions, housing configuration, installation depth, and maintenance requirements.
Product Selection & Procurement
When replacing a Standard Capacity HEPA filter, verify the nominal filter dimensions, actual dimensions, EN 1822 efficiency grade, rated airflow, initial pressure drop, final pressure-drop requirement, frame material, gasket type, operating temperature, and compatibility with the existing filter housing.
AccuraFil provides industrial and commercial air filtration products for facility managers, HVAC contractors, mechanical engineers, pharmaceutical facilities, healthcare organizations, cleanroom professionals, and procurement teams.
