I've had this on again off again mental debate

It's the usual 20x25, and I get the upgraded pleated version,

However, in my mind, the pleated version
restricts the air flow more so than the fiberglass - nature of the beast.

SO - when it gets really hot in the summer,
or below zero in the winter -
I temporarily pull the air filter out for max air flow...

Now, not sure why exactly.... thinking of pushing more "treated air" into
the ducts & house.
BUT - does it make any sense ?

Since the air stream is going faster across the heat exchanger (winter),
or the A/C A-coil (summer) maybe the air outflow is higher
but the temperature is not at the max....
I'll have to take a test run with my IR kitchen therm and point at the duct
vent.


Hmm,
Very funny! For one, blower speed is different between cooling and
heating mode. System is designed to work with filter. Air flow should
be certain amount with filter installed and your job is to replace it
regularly depending on your situation. My filter is 16x25x5 and every 4
month I put in new one(MERV 12 ones(
