Morphology
The meaning 'a device that removes particles from air' is directly and transparently composed from 'air' (the gas) + 'filter' (a device that removes impurities). This noun-noun compound follows a common, cross-linguistic pattern for naming devices or instruments, so a B1 learner who knows both constituents will readily infer the meaning.
Etymology
Air filter comes from the simple image of a filter catching dirt and pollen from the air as it passes through, like a net that holds back bad bits while clean air goes on. So an air filter is the part that removes 'dust' and small particles to make the 'air' cleaner.
