About this episode

This episode discusses the importance of filter testing in optimizing air quality and reducing costs in various facilities.

Major facilities worldwide spend millions each year on air filters, yet if those filters are not performing optimally, that investment can lead to wasted money and compromised air quality. This problem is universal, affecting smaller, everyday facilities just as much as large operations like data centres or hospitals. This episode strips away the confusing technical jargon to reveal how simple, on-site testing can bridge the gap between lab-ideal measurements and real-world results. Discover how to compare brands, understand the true ‘Total Cost of Ownership,’ and use little testing to unlock massive savings in electricity and maintenance. You will learn why resistance to airflow is key and how modern mobile testing labs provide precision results across different manufacturers. Joining host Dusty Rhodes is Jon Holmes, a specialist from Camfil. Jon has spent over twelve years in the air filtration industry, dedicated to helping facility managers bridge complex engineering concepts into practical, money-saving solutions.
