Optimal Filter Change Sweet Spot

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.
