Use the short Dyson machine code from the purifier or its support record. A product description such as purifier, heater or humidifier is too broad to select among these three replacement parts.
The compatibility lists below are deliberately limited to the machine codes retained from Dyson's current US support pages. A similar tower or a different regional machine needs its own source.
Three retained part groups
Open the model record for the complete compatibility list and manufacturer links.
| Part | Retained machine group | Filter description |
|---|---|---|
| 970341-01 | TP06 / HP06 / PH01 / PH02 | Combined HEPA and carbon replacement filter. |
| 968125-03 | DP01 / HP01 / HP02 | Genuine replacement purifier filter. |
| 965432-01 | Exact models on the published Combi Glass record | 360-degree Glass HEPA and activated-carbon filter. |
Why the complete machine code matters
HP01, HP02 and HP06 are different retained machine codes even though all begin with HP. The last two digits select a different documented part group.
A retail title can abbreviate the model list. Compare the part number and your machine code with the linked Dyson support page before choosing a seller or pack.
