re: MERV level on home AC filters in South Louisiana

Piggybacking on this: my hvac guy recommended I change the furnace filter a while back, so I swapped it with a MERV 11 furnace filter. I’ve also always run MERV 1 return air filters. Haven’t had any issues with my system and it’s 10+ years old now, but is that overkill? Should I ditch the furnace filter and run a MERV 5 or something in the return air or vice versa?

if you are doing 1" filters, go cheap/fiberglass.
