Looks. If you operate in a dusty climate, your filter will dirty faster, and vice versa.

Do you change air filter by looks or miles?

I go by looks, mine appear to stay clean for quite a few years.
By miles for the past 50 years. Air filters are a routine expense.
By looks, mileage or time, whichever comes first per owner's manual. When I open the air box I also vacuum the inlet side.
I blow them out from inside with. High pressure air a few times a year till they start getting faded and discolored. They last about forever keeping them clean like that.
I go by miles. On modern vehicles that get driven regularly in normal city/hwy conditions, usually 30k miles.
My severe service (short trip/infrequent/harsh use) vehicles get the same mileage based replacement intervals but 10 or 15k miles.
The Harley and old hot rod truck are visual based replacements, because I can see the filter condition without removal.

Looks. I can see the dirty side without disturbing the gasket at all due to the convenient arrangement and orientation on both of our Subaru's. The filter for the Forester looked good at 50k miles, but I changed it anyway. The filter sits vertically in the housing, and the bottom pleats were darker/dirter, but overall the filter looked just fine cleanliness-wise and structurally. I won't change the filter next time until it looks to need it, hopefully after another 50k miles or more.

Exactly! Manufacturer's recommendations have to assume you're on dusty roads more than average. I'm not, so I'm safe going well beyond their mileage numbers. I changed the filter in the Mazda every 100K to 120K, and never could detect any difference in power or fuel economy after a filter change.

I live in a somewhat less dusty environment. I look at it once a year to verify it is sealing and structurally intact. I have a plan to change it every 4-5 years due to age of the seals etc regardless of miles(kms).

Definitely looks but because I don't get much dust after a year I just change it.

Not a good practice:

I go 6 years or when the restriction gets to 11". So far I have changed it out due to time not miles(got 90k miles on my S2000 filter).
My '13 Jeep has 60k miles on it and still low restriction(8") so maybe change it out somewhere around 80k miles. Will let you know when I do change it out.

I just buy news air filters in the spring. They generally pick up lots of dust, sand, dirt over winter.
