This time-based approach often leads to filters being changed too early or too late, both of which are expensive mistakes.\nThis 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.\nJoining 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.\nTHINGS WE SPOKE ABOUT\nGoals of filter maintenance and replacement\nOptimal filter change is double pressure drop\nVisual dirt checks are subjective and unreliable\nMedia, area, shape affects filter lifespan\nWhy the MERV-A rating is crucial\nGUEST DETAILS \nJon Holmes serves as a specialist at Camfil.
