About This Product

Glass Microfiber Precision for Demanding HVAC Environments

  • AccuraFil High-Efficiency ASHRAE Cell Filter is a deep-pleated, extended-surface design filter made with glass fine microfibers, delivering consistent filtration efficiency throughout its full service life — unlike synthetic media filters whose efficiency can degrade as dust loading increases.
  • Engineered for a wide range of demanding conditions, including high humidity environments and variable air volume (VAV) systems where structural integrity and efficiency consistency under fluctuating airflow are critical requirements.
  • Available in single header, double header, or box-style frame configurations in GI, SS, Al, or MDF materials — with 6" and 12" depth options — providing flexibility for direct replacement of traditional pocket-style filters across diverse housing types.
  • Achieves MERV 11, MERV 13, and MERV 14 per ASHRAE 52.2. Supported by hemmed-edge aluminum corrugated separators for precise pleat spacing throughout service life.

  • Hemmed-edge aluminum corrugated separator for precise pleat spacing
  • Compact design replaces traditional pocket-style filters

Reliable Performance

  • Built to withstand extreme conditions — enhanced filter strength
  • Ideal for package systems, air handlers, and split systems
  • Suited for built-up filter banks and free-standing units
  • Available in 6" and 12" depth for flexible installation

Performance Attributes

Glass Microfiber Performance & Configuration Flexibility

  • Consistent Efficiency Throughout Lifespan: Glass fine microfibers maintain their filtration efficiency as dust load increases — the fiber matrix does not degrade or change pore structure over time, ensuring the rated MERV performance is sustained from first installation to end of service life.
  • High Humidity & VAV Resistance: Glass microfiber media retains structural integrity and efficiency under elevated humidity and variable airflow conditions, making it the superior choice over synthetic media in environments where moisture or pressure fluctuation is present.
  • Hemmed-Edge Aluminum Corrugated Separator: Precision-formed hemmed edges prevent separator migration and pleat convergence throughout the deep-pleated media pack, maintaining uniform airflow distribution and maximum effective filtration area across both 6" and 12" filter depths.
  • Multiple Frame & Header Configurations: Three frame styles and four material options provide precise compatibility across standard cell housings, built-up filter banks, air handlers, package systems, and free-standing units — enabling direct pocket filter replacement without housing modification.

Selection Guide

How to Select the Right ASHRAE Cell Filter for Your HVAC Application

  1. Identify your MERV rating and efficiency requirement

    MERV 11 for general commercial and light healthcare applications. MERV 13 or MERV 14 for commercial facilities, hospitals, laboratories, and LEED-certified buildings.

  2. Select the required filter depth

    Choose the 6" depth for standard cell housings with space constraints. Select the 12" depth for applications requiring maximum dust holding capacity and extended service intervals, or for high-capacity built-up filter banks.

  3. Choose the frame configuration

    Single header frames suit standard side-access filter housings. Double header configurations are used in walk-in or both-sides-accessible filter banks. Box-style frames provide maximum structural rigidity for demanding applications and are the preferred choice for free-standing filter units.

  4. Select the frame material and verify installation parameters

    Choose GI for standard applications, SS for corrosive or high-humidity environments, Al for weight-sensitive installations, or MDF where non-metal construction is specified. Confirm operating temperature does not exceed 176°F and that your AHU supports the 1.40" wg recommended final pressure drop.

Product Comparison

Performance Comparison: ASHRAE Cell Filter vs. Pocket Filters & Synthetic Deep Pleated Filters

Against conventional pocket bag filters, the ASHRAE cell filter delivers superior structural performance in VAV and high-humidity environments. Glass microfiber media retains its rated MERV efficiency as dust loading increases — pocket filters using synthetic media can experience efficiency drift as the media structure changes under load. The compact cell format also occupies less depth than equivalent bag configurations, simplifying retrofits in space-constrained housings.

Compared to synthetic media deep pleated filters, glass microfiber construction provides demonstrably higher sub-micron capture efficiency at equivalent MERV ratings. The hemmed-edge aluminum corrugated separator maintains more precise pleat spacing than expanded metal mesh across deep filter depths, ensuring the full media area remains active and evenly loaded throughout the service interval — directly translating to longer filter life and fewer change-outs per year.

Frequently Asked Questions

Product FAQ

What is an ASHRAE cell filter?

An ASHRAE cell filter is a deep-pleated, extended-surface air filter designed to meet ASHRAE 52.2 efficiency standards. The 'cell' format refers to the compact, self-contained filter unit with a rigid frame — available in single header, double header, or box-style configurations — that slots into standard cell-type filter housings and built-up filter banks. AccuraFil's ASHRAE cell filter uses glass fine microfiber media for consistent efficiency throughout its full service life.

Why use glass fine microfiber media instead of synthetic media?

Glass fine microfibers provide sub-micron filtration performance that synthetic media cannot match at equivalent thicknesses. The glass fiber matrix maintains consistent filtration efficiency throughout the filter's lifespan — it does not degrade, shed, or change pore structure as dust loading increases. This makes glass microfiber media the preferred choice when efficiency at 0.3 microns is a critical specification, achieving up to 99.999% particle capture.

What is a hemmed-edge aluminum corrugated separator?

A hemmed-edge aluminum corrugated separator is a precision-formed aluminum strip with folded (hemmed) edges that maintains consistent pleat spacing throughout the deep-pleated media pack. The corrugated geometry and hemmed edges prevent separator migration and media contact, ensuring uniform airflow distribution across the full filter depth and preventing the reduction in effective filtration area that occurs when pleats converge.

What HVAC systems is the ASHRAE cell filter suitable for?

AccuraFil ASHRAE cell filters are suitable for package systems, air handlers, split systems, built-up filter banks, and free-standing units. They are also specifically engineered for variable air volume (VAV) systems and high humidity environments where conventional pocket-style filters may degrade or lose structural integrity over time.

What frame and header configurations are available?

The AccuraFil ASHRAE cell filter is available in three frame configurations: single header, double header, and box-style. Frame materials include GI (galvanized iron), SS (stainless steel), Al (aluminum), and MDF, allowing selection based on application environment, chemical exposure, weight constraints, and housing compatibility.

What efficiency levels does the ASHRAE cell filter achieve at 0.3 microns?

AccuraFil ASHRAE cell filters achieve: MERV 11 at 99.97% particle capture at 0.3 microns, MERV 13 at 99.99%, and MERV 14 at 99.999% — all per ASHRAE 52.2 testing standards. MERV 14 at 99.999% is the recommended choice for pharmaceutical manufacturing, ISO cleanrooms, and hospital critical care environments.
