1. Design and Safety
Both fans use Dyson’s bladeless Air Multiplier™ technology for safe, smooth airflow — no fast-spinning blades or exposed heating elements.
The Dyson AM09 offers a minimalist design with a magnetic curved remote, while the HF1 introduces a compact, lightweight build and a clear LCD display for easy monitoring.
Both models are designed with automatic tip-over shut-off and child-safe edges, making them ideal for family spaces.
2. Heating Performance
The Dyson AM09 Jet Focus uses PTC ceramic plates to project warm air efficiently.
It features two heating modes:
-
Jet Focus Mode – Concentrated warmth for personal comfort.
-
Diffused Mode – Even heat distribution across the room.
The Dyson HF1, however, provides 20% faster heating thanks to improved ceramic plates and more powerful airflow projection. It can increase the room temperature by one degree in around 100 seconds.
For anyone seeking a Dyson heat and cool fan that reacts quickly and evenly, the HF1 stands out.
3. Cooling Efficiency
Both models double as a Dyson cool and hot fan, providing steady, refreshing airflow during warmer months.
The AM09 uses Dyson’s Air Multiplier™ technology to amplify air up to 15×, giving you consistent cooling without harsh drafts.
The HF1 improves on this by producing smoother, more efficient airflow that’s 25% quieter, even on higher settings — ideal for open-plan rooms or bedrooms.
4. Smart Control and Connectivity
Here’s where the Dyson HF1 shines.
While the AM09 works as a classic Dyson remote control fan with a magnetic remote for adjusting temperature, oscillation, and speed, the HF1 introduces full smart connectivity.
With the MyDyson™ App, you can:
-
Pre-heat your room remotely from 12–32°C.
-
Create weekly heating/cooling schedules.
-
Control via voice using Alexa, Google Home, or Siri Shortcuts.
This smart functionality makes the HF1 perfect for modern households that value automation and convenience.
5. Noise and Energy Efficiency
Dyson fans are known for their quiet operation, but the HF1 goes further.
The AM09 earned the Quiet Mark accreditation, being 75% quieter than its predecessor. The HF1, however, features improved acoustic engineering, reducing turbulence for an additional 25% noise reduction.
Its Sleep Mode runs whisper-quiet at 26dB, perfect for bedrooms or nurseries.
Both models use an intelligent thermostat to regulate temperature, but the HF1 adds smarter energy optimisation — making it up to 30% more efficient than standard heaters.
6. Ease of Use and Maintenance
Both models are incredibly simple to operate. Each includes:
-
One-touch oscillation
-
Manual tilt adjustment
-
Auto shut-off safety feature
-
Easy-wipe surfaces (no grilles or blades)
The Dyson HF1’s LCD screen and single-dial control make adjusting temperature and fan speed effortless, while the Dyson remote control fan function ensures you can manage comfort from your seat.
7. Verdict – Which Dyson Cool and Hot Fan Should You Buy?
If you prefer straightforward performance, the Dyson Hot+Cool AM09 is a proven, reliable choice for consistent all-season comfort.
But if you’re after smarter controls, faster heating, quieter performance, and app connectivity, the Dyson Hot+Cool™ HF1 Remote Link Pre-heat Heater and Cooling Fan is the superior model.
It’s efficient, elegant, and designed for the connected home — the next generation of Dyson heat and cool technology.
