- Scene_Cast2 6y agoDo they not? They have the same ratings scale, based on filtering certain particulate sizes.
- Der_Einzige 6y agoThat's BS. Look at the MERV rating. MERV 14 and above filters out increasingly large quantities of particles at the sizes of COVID virus particles and pollen. 4 inch thick furnace filters can easily be rated above MERV 16 (I run a MERV 16 filter in my home). For most peoples purposes, they are almost as good (and far cheaper) than HEPA.
