The health-threatening air pollution, especially from particulate matter (PM), has triggered increasing demands for developing low-cost and long-service-life air-cleaning technologies. In the present contribution, a range of high-efficiency textiles/metal–organic framework (MOF) composites (MOFs@textiles) air filters with excellent washable reusability is presented. By processing MOFs onto textile substrates via an eco-friendly solvent-free method to enable the microporous feature and also strong PM adhesion, we develop flexible, highly effective air filters with >95.00% PM removal efficiency (e.g., MiL-53(Al)@Aramid, PM 2.5: 95.30%, PM 10: 96.11%) under harmful air quality conditions (average PM 2.5 mass concentration > 280 μg m –3 and PM 10 > 360 μg m –3 ). Therefore, these MOFs@textiles are promising composites for producing efficient and recyclable out-/indoor air purifiers.
