I live in a suburb and drive half freeway. Not many miles per year. I find every three years I just replace my air filter and they never look really bad.. too much work to check them. Maybe I am just lazy. But I change my filters every 15 to 25 K mikes in any case. Purolater usually.
How often do you check or replace your air filter ?

Once a year in April so I'm ready for the summer driving

I replace it by the owner's manual, 30,000 or 50.000 miles. Often I exceed these numbers if it looks good. I usually check it every year or two.
I used to do it yearly but pretty much rely on oil analysis now. Our Taurus is over 80k on the air filter. Still looks good and I'll pick the dead bugs out of it occasionally. Silicon will generally start trending up as the filter degrades. The the filter has to reach a certain level of restriction before it is working at maximum efficiency.
Every oil change I open the box and vacuum out the big stuff and try to get the stuff stuck in the pleats. If it still looks clean I put it back. Normally I will change it at 20k regardless.
I used to be real stingy but I was shocked when a filter that looked perfectly usable created an oil burning scenario from lack of flow.
Once a year for my daily drivers.

Gentle vacuuming would be a lot safer---as would leaving it alone. The compressed-air nozzle routine is a proven method of liberating dust that will soon enter the engine.
How, exactly?
Check yearly and replace as needed. Usually change out every 2 years even though visually it looks decent. Cabin filter, once a year, regardless of visual inspection.
This is good.
Manufacturers usually state miles on the engine air filter, but it really depends on conditions. I visually inspected my truck filter after just 6k miles and it was filthy (was run summer to spring) so it got changed really early.
I check the AF ~ twice a year and replace as needed, maybe every 2 years.
Leave it in there until you want to change it. 20k miles if you're in a dusty area, 40k otherwise.
Those of you blowing, vacuuming, or banging out your filters are doing nothing productive. Neither is "inspecting" the filter. They don't become spontaneously clogged.

I check it every oil change since already under the hood.
15,000 miles, which is about 18 months for me. I always find a lot of grass in my airbox, from the yard companies blowing lawn clippings out onto main roads, and hauling grass clippings without covering them.
Years of maintenance and finding 2 filters which were apparently factory, one @70K the other @50K, has me in the 30K Club.
Those 2 oldies -both flat panel style- were out of vehicles with complete records. Sand fell freely from both as I lifted the elements out.
The velocity needed to lift sand particles through the "pressure drop zone" beneath the element makes me conclude they were nowhere near clogged. Still, 30K is what I decided.

When I'm bored. On my maintenance log it looks like between 30k and 60k. I'm on my 5th filter at almost 200k.
