Does it make any sense to buy more expensive filters that are alleged to
reduce allergens when another occupant of the house (the one who suffers
from allergies) insists on turning off the AC and opening windows as
soon as the outside temperature drops below 75F?

Thermostat war, huh?

Why would you want the AC on if it's below 75 anyway? You can have the
air filtered without using an AC, but filtering the air is pointless if
the windows are open.

No, it's not a thermostat war -- not a tmperature war, anyway. We could
leave the thrmostat set for 75F and set the fan switch to "on" rather
than "auto" and circulate filtered 74-degree air rather than have the
pollen, etc. coming in through the open windows with the unfiltered
74-degree air.

Why run the AC when it is 75 F outside? Because the air is humid.
I could never figure out why someone would run the AC all day for comfort,
then open the windows and fill the house with humid air. If the humidity is
low then no problem. I won't open them 'till 60-65F.

Because they enjoy having the windows open. Simple pleasure.
