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 particles as small as allergens and bacteria. And because they’re fully sealed, our filters trap pollutants, rather than leaking them back into the room.
Frequently asked questions
Dyson filters have been developed by the same engineers who make Dyson machines. The HEPA filter is made from borosilicate microfibers pleated hundreds of times, to capture 99.95% of ultrafine particles as small as 0.1 microns.2 While the activated carbon filter removes gases and odours.
HEPA stands for High Efficiency Particulate Air [filter]. HEPA grades refer to filter efficiency at a certain particle size. HEPA H13 is a filter with a 99.95% removal efficiency of particles down to 0.1 microns per litre of air. Dyson filters also capture 99.97% of particles down to 0.3 microns in size including common pollutants such as allergens, bacteria, pollen, and mould spores. Layered with activated carbon filter, Dyson purifiers capture both pollution particles and gases.
