Dyson filters by model family
Dyson’s fan-purifiers use a combined HEPA and activated-carbon filter that is unique to each generation. The design looks clean and hides the filter inside the loop, but it also means the HEPA and carbon are bonded together, so you replace both even when only the carbon is spent. Match the filter to your model family before buying.
| Dyson family | Filter | Typical UK price* |
|---|---|---|
| Pure Cool (TP series) | Combined HEPA + carbon (360°) | ~£50–£65 |
| Pure Hot+Cool (HP series) | Combined HEPA + carbon (360°) | ~£55–£75 |
| Purifier Cool / Big+Quiet | HEPA H13 + carbon (model-specific) | ~£60–£90 |

How often does a Dyson filter last?
Dyson estimates about 12 months at 12 hours a day, shown as a countdown on the unit and in the MyDyson app. Heavy use, pets or a spell of wildfire or bonfire smoke will shorten that considerably. Because the countdown is based on runtime rather than a direct measurement, treat it as a guide and check the filter yourself — our notes on how often to replace a filter cover the tell-tale signs, such as weaker airflow or a musty smell.
Can you wash or reuse a Dyson filter?
No. Dyson filters are sealed HEPA-plus-carbon units and are not washable — water mats the fibres, neutralises the electrostatic charge and can grow mould, ruining the media for good. Only the outer surfaces and any mesh should be wiped clean; the filter itself is replace-only. If you are tempted to rinse one to save money, read can you wash air-purifier filters first — a washed HEPA filter can look fine and perform terribly.
Why Dyson filtration gets expensive
A £60–£90 filter every year is among the highest ongoing costs of the mainstream brands. Two things drive it: the filter is proprietary, so only Dyson and approved sellers supply it; and the airflow through a slim tower is modest, so clean-air delivery per pound spent is comparatively low. You are paying a premium for the styling, the heating or cooling function and the app — not for better particle capture.
Does the carbon deal with smells?
The carbon layer does tackle gases and odours — cooking smells, smoke odour, VOCs — while the HEPA layer handles particles. That is the correct pairing, because a particle filter alone cannot remove gases. The limitation is quantity: a slim bonded filter holds only a modest carbon bed, so heavy odour loads saturate it well before the HEPA layer is exhausted. Our activated-carbon guide explains why carbon weight matters for real odour control.
A cheaper way to clean the same air
Dyson’s HEPA capture is excellent on paper, but a high-airflow purifier running standard MERV-13 media clears a room faster in practice by moving far more air, and it re-filters for a fraction of the price. It won’t give you Dyson’s looks, heating or app, but for pure air-cleaning value it is hard to beat.

Should you keep feeding a Dyson?
If you already own a Dyson and like it, buying genuine replacement filters on schedule is the sensible choice — the machine only works as intended with the correct filter fitted and sealed. The question is really about the next purchase. If low running cost and maximum clean air per pound are your priorities, a high-airflow standard-media machine will out-clean a slim tower for far less over its life. If you value the styling, heating or cooling and app control, the Dyson premium may be worth it to you — just go in knowing the filters are the ongoing cost, not the machine.
