A cleanroom is a controlled environment used for highly sensitive manufacturing operations, healthcare facilities, and scientific research laboratories. The level of cleanliness in a cleanroom is defined by the allowable concentration of airborne particles, with other environmental parameters (e.g. temperature, air pressure, and humidity) controlled as necessary. Cleanrooms are widely used in the medical, bio/pharma, and microelectronics industries. Efficiently and reliably maintaining the level of cleanliness needed for these sensitive operations requires the use of high-performance filtration technology. In addition to airborne particulates, airborne molecular contamination (AMC) is an increasingly important environmental control parameter requiring molecular or gas-phase filtration.

For your most critical filtration applications, you can trust the experts at Hollingsworth & Vose (H&V). We are the global leader in HEPA and ULPA filter media for cleanroom filters. Our industry-leading filtration solutions control particulate and gas-phase contamination with lower energy consumption, affecting a significant portion of cleanroom operating costs. H&V cleanroom filtration media continues to set the standard for performance, quality, and reliability. 

Not all HEPA and ULPA filter media are made the same way. While other media may meet the efficiency standards of ISO 29463 and EN 1822, many lack sufficient quality and reliability. These deficiencies result in air filters with uneven airflow distribution and higher operational expenses. Choosing subpar filter media can have considerable indirect and direct effects for cleanroom owner-operators, including yield loss, expensive downtime, and environmental and safety hazards. Cheap filter media can end up costing much more over the long term.

Role of Cleanroom Filters

The filtration system is the heart of the cleanroom and is what keeps the cleanroom free of contaminants that can interfere with the quality of the product or process. Cleanrooms utilize multiple stages of particulate and gas-phase filters to remove contaminants from the environment. The flow of air in a cleanroom is carefully engineered to facilitate the removal of impurities. Filter media and filter design play a major role in ensuring the desired airflow characteristics of a cleanroom and the energy costs to operate them.

Cleanroom filtration brochure

At H&V, all of our high-efficiency cleanroom filter media are engineered for superior filtration performance, low pressure drop, and outstanding pleatability. The best filter media makes the best filters. Our broad product range includes:

  • Microglass media: Suitable for mini-pleat, deep-pleat, and compact filters, our microglass media has superior processing characteristics and a lower pressure drop compared to competitive media with the same efficiency. It features up to 14% lower energy consumption and high media uniformity, which results in the low variation of efficiency and pressure drop, enhanced airflow uniformity, and decreased drop-outs during filter production and validation testing. H&V’s microglass filter media also offers improved tensile strength compared to low-cost microglass media, leading to reduced failures during normal operation, installation, and transportation.
  • Molecular filtration media (MFM): Our MFM products are designed for pleated AMC filter applications to remove molecular/gas-phase contaminants.
  • Low boron microglass media: H&V’s low boron microglass filter media are designed for semiconductor fab cleanrooms.
