No need to clean air ducts from filter to inside cabin.
Most vehicles didn't have cabin filter until mid-late '90. Most drivers didn't change cabin filter until it totally clogged because they didn't it's there.
Many vehicles are easy to change cabin filter, only simple tools and few minutes, but garage/mechanic need to make profit and few minutes of labor isn't free.
