Maintain the optimal performance of your Dyson air purifier with the Dyson 360-degree Glass HEPA & Carbon replacement filter. It's made from borosilicate microfibres, pleated hundreds of times, to capture 99.97% of pollutants as small as 0.3 microns. While the activated carbon filter removes gases and odours, the sealed HEPA filter traps pollutants, rather than leaking them back into the room. | Dyson 360 Glass HEPA & Carbon Filter (965432-01)
