In detail: Dyson HP1 Air Purifier, Fan and Heater
The Dyson Purifier Hot+Cool HP1 brings three appliances together in one unit: a HEPA H13 air purifier, an Air Multiplier fan and a ceramic-plate space heater. A rare combination in this segment, designed to stay out year-round rather than get put away between seasons.
The filtration system, fully sealed to HEPA H13 grade, captures 99.95% of microscopic particles and allergens down to 0.1 microns: dust, pollen, pet dander, bacteria. A layer of activated carbon is added to absorb gases, odours and volatile organic compounds. Built-in sensors analyse air quality in real time and automatically adjust airflow in Auto mode, so the unit only uses energy when it needs to.
On the cooling side, Air Multiplier technology amplifies the air drawn in at the base up to 15 times, projecting over 290 litres of purified air per second in a smooth, steady stream, with oscillation programmable up to 350°. In winter, positive temperature coefficient ceramic plates heat the whole room quickly, with a built-in thermostat that delivers up to 30% energy savings compared with an unregulated heater. Dyson states an effective coverage of up to 27 m² (290 sq ft).
The unit is controlled via a curved, magnetised remote that stores directly on top of the column, or through the MyDyson app, compatible with Amazon Alexa, Google Assistant and Siri: real-time air quality tracking, timer scheduling, filter change alerts. Night mode, 50% quieter than maximum setting, allows bedroom use without disturbing sleep, with an LCD screen that dims automatically in the dark.
Points worth knowing before buying: at maximum setting, the unit becomes clearly audible (up to 63 dB(A)), and its price, close to £550, remains high compared with a purifier or a space heater bought separately. The HEPA and activated carbon filter needs replacing about once a year under typical use. The Dyson HP1 is aimed above all at buyers looking to replace several appliances with one, design-led, connected unit backed by a 2-year manufacturer warranty.

Comparison
Priced around £300 to £550, the Dyson HP1 is regularly compared with other air-treatment units from the brand, notably in searches such as "Dyson HP1 vs PC1" or "HP1 or HF1". Here is how it stacks up against the Purifier Cool PC1, a purifier-fan with no heating function, and the Hot+Cool HF1, a heater-fan with no purification, based on specifications published by Dyson.
| Criterion | Dyson HP1 | Dyson Purifier Cool PC1 | Dyson Hot+Cool HF1 |
|---|---|---|---|
| HEPA H13 purification | Yes | Yes | No |
| Heating | Yes, ceramic plates | No | Yes, ceramic plates |
| Air Multiplier fan | Yes, 290 l/s | Yes | Yes |
| Coverage area | 27 m² | 23 m² | Not applicable (no purification) |
| Observed price | ≈ £549 | ≈ £350 | ≈ £399 |
In short, the Purifier Cool PC1 suits anyone who only wants purification and cooling, at a lower price, while the Hot+Cool HF1 targets those who need heating and cooling only, without purification. The HP1 remains the only one of the three to combine all three functions in a single unit, a genuine selling point for anyone who wants just one appliance to leave in the room all year round.

Our tester's verdict: Christophe Delpuech
We set up the Dyson HP1 in a living room of about twenty square metres for a full winter, curious to see whether it could genuinely replace a space heater, a fan and an air purifier all at once. On heating, the result is clear: the ceramic plates raise the perceived temperature within minutes, and the built-in thermostat stops the unit running once the set temperature is reached. On purification, Auto mode is genuinely convincing: the display shows fine particle levels dropping live after an evening of cooking or a window left open onto the street. Night mode stays discreet and doesn't disturb sleep, which isn't the case at maximum setting, where the airflow becomes clearly audible, closer to a hairdryer than a whisper. Summer cooling does the job of a decent fan without ever turning into an air conditioner, a distinction worth keeping in mind on a proper heatwave day. What's left is the price, high for a unit that remains, at its core, a purifier with extras: but for anyone who genuinely wants a single object to leave in a room all year round, warm, cool, air purified, the trade-off feels fair to us.
Frequently asked questions: Dyson HP1 Air Purifier, Fan and Heater
Both purify the air with a HEPA H13 filter and cool the room, but only the HP1 adds a heating function via its ceramic plates, useful for year-round use rather than just the warmer months.
Yes, its positive temperature coefficient ceramic plates deliver an even flow of warm air, with a built-in thermostat that cuts power once the target temperature is reached, for up to 30% energy savings.
Dyson states an effective coverage of up to 27 m² (290 sq ft), roughly a living room or a large bedroom. In a bigger room, several purification cycles will be needed for optimal results.
Noise level ranges from 46 dB(A) at low speed to 63 dB(A) at maximum setting. Night mode, 50% quieter than maximum, suits a bedroom, while the top speed is clearly audible.
The combined HEPA H13 and activated carbon filter typically needs replacing once a year for 12-hour daily use, or every 6 months under continuous 24-hour use. The MyDyson app and LCD screen flag when it's time to change it.
