HEPA Filter Certification

HEPA filters are used in many situations to protect products, people and the laboratory environment. For best performance and safety, HEPA filtration devices must be regularly tested and re-certified or replaced.

According to ASHRAE: “Because a HEPA manufacturer cannot be responsible for transportation of the filters to the user or handling and installation, many applications require additional in-place testing to ensure the installed integrity of the HEPA filter. This in-situ certification involves the use of atomized poly-dispersed DOP or poly alpha olefin (PAO) to scan for filter leaks.

This method can reveal leaks in the HEPA filter and frame or housing gaskets and/or seals. This is especially important in systems that involve filtration of hazardous or infectious materials.”

Manufacturers test each HEPA filter according to methodologies as outlined in Recommended Practices (RP) as published by the Institute of Environmental Sciences and Technologies (IEST) and filter test methods by the International Organization for Standardization (ISO). Filters are challenged with particles or aerosols of specific size and the penetration of each filter is so recorded.

Why Does NEBB Certification matter?

NEBB (National Environmental Balancing Bureau) Certified for Cleanroom Certification. Established in 1971, NEBB is the premier international certification association for firms that deliver high-performance building systems. This includes heating, ventilating and air-conditioning systems and sound and vibration testing. This also includes testing and certifying laboratory fume hoods, electronics, and biological clean rooms. Our team must complete extensive training and testing in order to attain NEBB Certification status.
