Filters were changed 2 years ago at 5 year service

If my math is correct, you average between 4 and 6,000 miles per year.

That means that in the last two years you put on between 8 and 12,000 miles - hardly enough to even think about changing the air filters!

Your math is off. My '18 E300 is 7 years old. (built 7/17 & delivered 8/17) My annual mileage is: 5087, 4897, 4071, 2573, 3414, 2484 and 2474 respectively. Filters were changed because I was caught in a dust devil. Many services are performed ahead of schedule due to need.
