How to distinguish medium-efficiency bag filters by color ?

Mar 13, 2025Leave a message

Introduction

The efficiency grades of medium-efficiency bag air filters can usually be distinguished by color, and different colors correspond to different filtration efficiencies. According to common standards:

F5: It is mostly white in color, with a filtration efficiency of around 40% - 60%.

F6: Generally green, the efficiency is in the range of 60% - 80%.

F7: It often appears pink, and the efficiency range is 80% - 90%.

F8: The color is light yellow or yellow, and the efficiency is 90% - 95%.

F9: Dark yellow or white, with an efficiency of over 95%.

However, in general, distinguishing by color is a relatively intuitive and convenient preliminary judgment method, which can help users quickly understand the approximate filtration efficiency and applicable scenarios when selecting and using medium-efficiency bag air filters.
