Discover how clean air can affect the quality process for you and the workplace from world leading experts.
We find out how controlling air can bring benefits to production plants and facilities, the health of people who work there, and bringing greater efficiencies to your final product.
We’re also joined by experts from Camfil, a world leader in the development and production of air filters and clean air solutions, on what they are doing to keep air clean and safe.
Relying on a fixed calendar schedule for HVAC filter changes could be actively draining your facility’s budget and increasing energy costs. This time-based approach often leads to filters being changed too early or too late, both of which are expensive mistakes.
This episode reveals the crucial data point you should use—the optimal ‘sweet spot’ for replacement based on pressure drop—and explains why visually checking for dirt is dangerously subjective. We also demystify the MERV rating, focusing on the critical detail that truly protects occupants and equipment, not just the sticker price.
Joining us is Jon Holmes, a specialist from Camfil. With over a decade of experience, Jon has spent years helping facility managers bridge the gap between complex engineering principles and practical, breathable air solutions.
THINGS WE SPOKE ABOUT
Goals of filter maintenance and replacement
Optimal filter change is double pressure drop
Visual dirt checks are subjective and unreliable

QUOTES
Changing a filter at twice its initial number based on which is pressure drop or resistance to airflow… That’s the optimal sweet spot. – Jon Holmes
If you have a variable frequency drive, you can save a tonne of money by actually replacing that filter, because it’s cheaper to buy a new filter than to pay the energy bill to continue pulling air through it. – Jon Holmes
So the gold standard to know when a filter is due to be replaced is a resistance to airflow or pressure drop. – Jon Holmes
