Optimal indoor air quality starts with a high efficiency air filter — but it also requires property managers, HVAC professionals, and others who work with air filtration systems to understand how best to use and maintain their equipment. To answer their questions — and to provide a knowledge base to draw from — Camfil Farr, the world’s leading provider of clean air solutions, has published a new technical bulletin addressing key aspects of operating HEPA and ULPA commercial air filters.

The HEPA & ULPA technical bulletin — available free of charge at Camfil Farr’s Literature Library was written by Sean O’Reilly, the Global Director of Cleanroom & Life Sciences Segment at Camfil Farr, with input from Steve Devine, the company’s Vice President of Research and Development. Leveraging their decades of experience in the air filter industry, the publication offers insight on a variety of common issues and questions, including:

o How long will a HEPA air filter last?

o What are HEPA leaks?

o What is the recommended final pressure drop?

o What type of filter media is used in a HEPA filter?

The technical guide also delves into testing methods and test details, gel sealants, and HEPA repair. Readers will learn that the recommended shelf life of a HEPA filter is 10 years (when stored in its original packing); that a good rule of thumb is to replace filters when the pressure drop reaches two times the initial pressure drop; and that patching does not shorten the life of a filter — when it is a factory patch, or a field repair performed by trained personnel using recommended methods and materials.

Camfil Farr’s latest publication isn’t just a guide to cutting-edge commercial air filters — it is a guide to getting the most out of them, and making indoor environments as healthful and comfortable as possible.
