Morphology
The meaning is directly compositional: combining 'air' (the atmosphere) with 'cleaner' (something that cleans) yields an item that cleans air, so a learner who knows both words can infer the device function. Although 'cleaner' can also mean a cleaning product, the noun phrase pattern (X cleaner = device or product that cleans X) is common cross-linguistically, making the sense transparent to a B1 learner.
Etymology
Air cleaner is a literal compound: air is the gas around us and cleaner is something that makes things clean, so an air cleaner uses a filter to 'remove' dust and tiny bits from the air, which is why it means a device that makes indoor air 'clean'.
