In the past filters had manufacture date on them. At least 2 cars I bought 7-8 years old had factory mounted filters in them.
Depends where you drive - you might check filters for pollution.
Having filter minders on my cars, I routinely make 100,000 miles on engine air filters, but lately bought car from TN and insects are everywhere - even inside lights.
