HVAC Filters Explained | Types, MERV Ratings, HEPA, Pre-Filters & Functions #hvacfilter #hvac

HVAC Filters Explained! What are the different types of HVAC filters? What is the difference between a pre-filter, fine filter, HEPA filter, bag filter and activated carbon filter? What does MERV mean? And why does filter pressure drop increase when a filter becomes dirty? In this video, we explain the major types of HVAC air filters, their functions, locations, applications, filtration efficiency, pressure drop and selection considerations. ⏱️ CHAPTERS 00:00 Introduction 01:12 What Is an HVAC Filter? 01:44 Why HVAC Filtration Is Important 03:07 Panel Filter 04:05 Pleated Filter 05:07 Bag Filter 06:10 Cartridge Filter 07:06 Washable / Permanent Filter 08:10 Activated Carbon Filter 09:25 HEPA Filter 10:45 ULPA Filter 11:45 Electrostatic Filter 12:42 Pre-Filter vs Fine Filter 13:40 Filter Ratings: MERV 15:03 Understanding Air Filter Standard 16:38 Common Air Filter Problems 17:17 How to Choose the Right Air Filter 19:26 Common Filter Mistakes 20:21 Final Summary In this video, you will learn about: • HVAC filter types • AHU air filters • Pre-filters • Fine filters • Panel filters • Pleated filters • Bag filters • Cartridge filters • Washable filters • Activated carbon filters • HEPA filters • ULPA filters • Electrostatic filters • MERV ratings • Filter pressure drop • Differential pressure monitoring • AHU filter selection • HVAC air filtration This video is useful for HVAC Engineers, ACMV Engineers, MEP Engineers, Mechanical Engineers, Building Services Engineers, Site Engineers, HVAC Technicians, Commissioning Engineers, Designers and Engineering Students. IMPORTANT: Actual filter selection should be based on the project requirements, applicable standards, manufacturer technical data, required airflow, filtration efficiency, pressure drop, fan capacity and maintenance requirements.
