MERV 8 vs MERV 11 AIR FLOW The better an air filter is at trapping particles, the quicker it will get maxed out. If you’re worried about the effects of breathing in fine air particles, that’s another reason to choose a MERV 11 air filter over a MERV 8 air filter. Fine air particles are 2.5 microns and smaller.
