I have a 3 year old Trane XR 80 furnace with a coil for CAC. The
furnace came with one of those cleanable filters. I have tried in the
past those 3M allergan filters and I think they restrict the air more
than the stock filter, which might (or might not) affect the cooling of
the house. I'm just wondering if anyone else noticed any performance
difference when using these allergan filters. It seems that if I use my
stock cleanable filter I will get more airflow and might cool the house
better.

The balancing act is that a more restrictive filter keeps the air
cleaner through the coil. If the coil gets clogged with dust, it's
expensive to have it removed and cleaned. I'd vote a better quality
filter, and cleaner air.
