Morphology
The meaning 'to make the air in a space smell cleaner or more pleasant' is directly and transparently derived from combining 'freshen' (to restore freshness) with 'air' (the atmosphere in a space); the verb + noun composition is literal and follows standard English patterns. This is a common, compositional construction found across languages, so an average B1 learner who knows both constituents would readily infer the MWE's meaning.
Etymology
Freshen the air comes from the simple image of opening windows or bringing in plants so new, clean air moves into a room. The word freshen means to make something clean or new and air is what you breathe, so the phrase now means 'to make the air smell cleaner or more pleasant'.
