Replacement purifier filters High-performance filters. Only from Dyson.
Dyson purifier filters have been developed by the same engineers who make Dyson machines. Made from borosilicate microfibers pleated hundreds of times, they capture gases and 99.95% of harmful pollutants.¹ And because they’re fully sealed, our filters trap pollutants, rather than leaking them back into the room.
We recommend replacing your filter every 12 months. That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room.
