Replaced cabin air filter

Truck is approaching a year old so decided to change the cabin air filter. Straight forward project to lower the glove box lid giving good access to the filter. Found this one on Amazon for $12
The replacement filter was noticeably heavier than the OE. Not sure the charcoal is of any value but we'll see. Part of the year I live on an unpaved road

That looks like a good replacement. FYI, others have complained that 'upgrading' to a HEPA filter resulted in such restricted airflow that they removed them. Additionally, Ford has changed the part # from FP-89 to FP-100-A, but there appears to be no difference.

I read the review where the guy installed in a Maverick and thought it slowed airflow and was not as cool.... however my logic says if airflow is lower air temperature would be lower too

Ait temp has nothing to do with flow IMO
Science doesn't support that. If anything, stronger flow of cool air would cool faster.

As an experiment, on a hot summer day, set the AC temperature to a low setting and turn the blower on high, then run the blower on low. I have found air temperature to be few degrees cooler when the blower was at a lower speed. Air, as it moves across the evaporator has more time, at the lower air volume, to have heat removed. In any case it's moot. If the new filter adversely affects comfort, I'll replace it.

True if you could stop air flow you could make ice
As long as air blows out vents seemingly unrestricted, filter need not be changed.

Admittedly the OE filter was far from being restricted but had collected some dust. Maybe I'll just blow it out and use as replacement a year from now!

You don't even need to clean it. The truth is, a dirty air filter cleans better than a new one. Not greater airflow through it, but removes more/smaller particles. If you look at a bright light thru a cheap/basic (not HEPA) filter, you can see specs of light or lighter spots. Look thru a dirty one, and no light seen, as dirty blocks those "holes", therefore fewer fine particles get thru.

Should we use the same logic for the oil and air filter? A dirty oil and air filter cleans better than a new one?

Air filter, yes. Fuel filter, yes. Oil filter no, because either you have enough oil pressure or you don't; you never know when engine will quit due to too low pressure, and unless you carry a spare filter, and don't mind changing it at the side of a road, I do not recommend it.
