Dyson Hot+Cool HF1: Two-Minute Review
The Dyson Hot+Cool HF1 is a sleek and smart fan heater featuring the bladeless and aesthetically pleasing design we expect from Dyson. With a premium list price of £399.99, the Dyson Hot+Cool HF1 is currently available in the UK through Dyson and a few other retailers. Sadly, it’s only available in the UK at the time of publishing, but we’ll provide updates if it becomes available internationally.
The HF1 offers ten fan speeds, three oscillation options up to 70 degrees, a heater that can reach temperatures up to 90ºF (32ºC), and exciting smart features. During testing, I found the HF1 very efficient in both Cool and Hot modes. The lowest setting delivered a gentle breeze from six feet away, making it comfortable while sitting on the couch.
There are multiple ways to control the HF1: onboard controls, a remote, and the MyDyson app. The app provided seamless access to the full range of settings, including timers, scheduling, historical ambient temperature data, and the ability to turn on heat mode remotely—perfect for coming home to a warm room. While the remote mostly worked well, it was occasionally patchy in its communication with the unit.
The fan’s noise level was comparable to similar fans tested. It was generally quiet enough to sleep near, although the Hot mode produced a brief period of increased noise when heating up, which could be disruptive for light sleepers.
For families with children or pets, note that the metallic edging at the front of the air purifier can become very hot quickly. Additionally, the child lock feature applies only to onboard controls, not the remote, which might be inconvenient if you have curious toddlers or pets around.
Overall, the Dyson Hot+Cool HF1 is an efficient and convenient fan heater. While the price is high, its performance and smart features justify the cost for those who value these qualities.
Price & Availability
- List price: £399.99
- Launch date: October 2025 (UK)
- Availability: UK only at time of publishing
The HF1 is a premium product with a premium price tag. It costs £150 more than the Dyson Cool CF1, which is reasonable considering the addition of Hot mode and smart features. The HF1 is available through Dyson, Currys, and other retailers in the UK.
If you have the budget, the Dyson Hot+Cool HF1 offers good performance and several handy features. However, it’s worth considering its drawbacks—such as noise in Hot mode, child lock limitations, and price—before making your decision.
Value for money score: 4 / 5
Design and Features
- Small and lightweight design, adjustable tilt
- 10 fan speeds
- Heater output up to 90ºF / 32ºC
- MyDyson app with extra settings, including a pre-heat function
Setting up the Dyson Hot+Cool HF1 was quick and simple. Attaching the plastic base plate and connecting the device to the MyDyson app took only minutes. The HF1 has a maximum diameter of 8 inches (20.4 cm) with the base attached, but at 23 inches (58.5 cm) tall, it may feel slightly tall for desktop use. However, it worked perfectly well on the floor.
You can slightly adjust the vertical airflow angle by tilting the fan’s body forward or backward. The bladeless design makes it easy to clean and safer for families with curious children or pets.
The HF1 can oscillate at 15°, 40°, or 70°, and uses ceramic heater plates combined with Air Multiplier technology to heat a room quickly—Dyson claims it can raise the whole-room temperature by 1ºC within about 100 seconds.
Like the Dyson Cool CF1, the HF1 comes with a magnetic remote control that stores conveniently on top of the loop amplifier. The remote controls power, oscillation, fan speed, temperature, sleep mode, timer, and child lock.
Where the HF1 stands out is its integration with the MyDyson app, which offers advanced settings, historical temperature data, outdoor air quality information, and easy remote control from anywhere. You can also connect it to your smart home system for voice control.
One particularly exciting smart feature is the ability to preheat a room to your desired temperature before you return home.
Design score: 4 / 5
Performance
- Good performance for size in both Cool and Hot modes
- Easy to control via app and remote
- Generally quiet, but noisy briefly when warming up in Hot mode
Using the HF1 was straightforward, especially with the MyDyson app. The remote was handy but sometimes lagged or failed to register commands.
From six feet away, the lowest fan speed produced a subtle breeze when oscillating. Increasing speeds delivered a stronger airflow, with top speed producing a noticeable breeze but some noise (about 45dB from 6 feet away), comparable to moderate rainfall. The HF1’s noise levels in Cool mode ranged from a whisper (29dB on speed one) up to 50dB on speed ten, making it louder than some competitors at top speed.
The oscillation noise was about 28dB and subtly reminiscent of a document scanner’s hum—quiet enough to sleep with for most.
Testing in Hot mode, I found the metallic edges near the air outlet became too hot to touch within minutes, so caution is advised around children and pets. The heating began slightly noisy but settled after warming up, with sound levels around 42dB initially, dropping to 37dB.
The HF1 managed to raise the room temperature by 1ºC in under two minutes, though accuracy may vary across larger rooms. An auto-adjusting Cool mode based on ambient temperature would be a nice addition to complement the Hot mode’s smart control.
Regarding safety, the child lock currently restricts onboard controls only; the remote remains accessible. Extending the lock to the remote would improve safety and prevent accidental use by children.
Sleep mode dims the display and lowers fan speed, but the display does not turn off completely in Heat mode. For overnight heating, the HF1 can start heating when the temperature drops; however, the initial volume increase in Hot mode could disturb light sleepers. A gradual heat increase in sleep mode would improve comfort.
Overall, the Dyson Hot+Cool HF1 delivers impressive airflow and user-friendly control in a portable, lightweight design. While Light sleepers might prefer quieter alternatives for overnight heating, other users will appreciate its convenience and performance.
Performance score: 4 / 5

How I Tested the Dyson Hot+Cool HF1
I used the Dyson Hot+Cool HF1 in multiple locations, including on different surface heights and near my bed. After unboxing and assembling the base, I connected it to the MyDyson app and explored all settings. I tested all fan speeds in Hot and Cool modes, monitored sound levels, and evaluated the app and remote controls for responsiveness and convenience.
Over several nights, I used the HF1 in Hot mode with the timer set to avoid overheating, helping me understand its suitability for overnight heating. I also paid attention to how quickly it heated rooms and the noise generated during operation.
