Webinar - Filtering Reality in HVAC Filtration
2026-01-07 09:00 - 10:00
Filtering Reality in HVAC Filtration
Wednesday, January 7 | 12:00 – 1:00 PM ET

An ACCA Codes & Coffee Webinar

Air filters often claim to solve a myriad of problems related to indoor air quality. What is true? What is hyperbole? What are some unintended consequences of “good” filters?
Topics to be covered:

How much filtration do you really need? MERV 11?
What is going on in “the industry?”
ASHRAE 62.2 – What is adopted by code? Is it enough?
What are the barriers to good filtration?
Code is the minimum. Is this good enough?
What about wild fires and other pollutants?

Join our host David Bixby, ACCA manager of codes, and our panel of experts below. We’re going to discuss factors when choosing the right filter, MERV ratings, HEPA, and strategies for filters with high resistance.
