Contact Our Experts Design & Engineering Selection Guide How to Select the Right HEPA LF Filter for Your System 1 Identify your required EN 1822 filter grade H13 (≥99.95% MPPS) is recommended for hospitals, laboratories, and pharmaceutical production areas. H14 (≥99.995%) is required for ISO Class 3–5 cleanrooms, aseptic filling lines, and critical surgical environments. U15 (≥99.9995%) serves the most demanding semiconductor fabs and ultra-clean process environments. 2 Choose standard or PTFE media Standard micro glass fiber paper media suits the majority of HVAC and cleanroom applications. Select PTFE membrane media for environments requiring superior chemical resistance, humidity tolerance above 90% RH, or applications involving aggressive process gases and solvents. 3 Select the appropriate filter depth Choose 2.6" or 2.96" for compact terminal housing and space-constrained laminar flow modules. Select 3.55" or 4.6" for standard laminar flow ceiling systems and AHU final filter banks. Choose 5.96" for maximum dust holding capacity and the longest achievable service intervals. 4 Confirm frame material and gasket compatibility Standard extruded anodized aluminum frames suit most terminal housing and laminar flow systems. Specify GI or SS frames for corrosion-sensitive or washdown environments. Confirm PU or Neoprene gasket compatibility with your housing seal interface before ordering. 5 Verify system pressure drop constraints Confirm your fan or blower capacity can maintain design airflow within the maximum recommended final pressure drop of 2.00" wg. The mini-pleat geometry delivers minimum initial resistance, extending the usable life before this limit is reached. Product Comparison HEPA LF vs. Conventional HEPA Box Filters Compared to conventional deep-pleat HEPA box filters, AccuraFil HEPA LF mini-pleat panels deliver significantly greater filtration surface area within an equivalent frame footprint. The result is lower initial pressure drop, higher airflow capacity per unit, and extended service intervals — reducing the total cost of filter ownership in high-change-frequency cleanroom and hospital environments. The individual EN 1822 scan test on every unit distinguishes the HEPA LF from batch-tested alternatives, providing the per-unit performance assurance required by pharmaceutical GMP, hospital infection control, and ISO cleanroom qualification protocols. Frequently Asked Questions Product FAQ What is a HEPA LF Laminar Flow HEPA Air Filter? A HEPA LF (Laminar Flow) filter is a high-efficiency HEPA-grade air filter built with mini-pleat media pack construction. The mini-pleat geometry maximizes filtration surface area within a compact panel profile, delivering ultra-high airflow at low pressure drop. It is designed for laminar flow systems, terminal housing, and critical cleanroom applications requiring H13, H14, or U15 filtration per EN 1822. What EN 1822 grades are available for the HEPA LF filter? AccuraFil HEPA LF filters are available in H13, H14, and U15 grades per EN 1822, with MPPS efficiencies of ≥99.95%, ≥99.995%, and ≥99.9995% respectively. H14 and U15 are suitable for the most demanding pharmaceutical aseptic manufacturing, semiconductor fabrication, and ISO Class 3–4 cleanroom environments. How is each HEPA LF filter tested? Every AccuraFil HEPA LF filter undergoes individual scan testing per EN 1822 to ensure completely leak-proof performance. Individual test results are printed directly on each filter unit, providing full traceability and quality assurance for regulated industries including pharmaceutical GMP and hospital infection control. What frame options are available for the HEPA LF filter? The standard HEPA LF frame is an extruded, anodized aluminum profile. Optional frame materials include galvanized iron (GI), standard aluminum (Al), and stainless steel (SS) for applications requiring enhanced corrosion resistance, hygienic washdown construction, or compatibility with specific terminal housing interfaces. What filter depths are available for the HEPA LF? AccuraFil HEPA LF filters are available in five depth options: 2.6", 2.96", 3.55", 4.6", and 5.96" to accommodate a wide range of terminal housings, laminar flow ceiling modules, and final-filter AHU configurations. The 5.96" depth provides maximum dust holding capacity and the longest service intervals. AccuraFil · Clean Air Solutions Ready to Get Started?
