Dyson Hot+Cool Fan Heater AM09 Review (2025): Worth the Investment?
Last Updated: October, 2025
Product Overview
The Dyson Hot+Cool Fan Heater AM09 (Black/Nickel) is a premium, year-round comfort solution for homes and offices. It delivers quick, even heat in winter and smooth, cooling airflow in summer—all via Dyson’s bladeless Air Multiplier™ technology for safety, simplicity, and style.
Want cleaner indoor air alongside temperature control? Pair the AM09 with a dedicated purifier like the
BLUEAIR Air Purifier for Medium Rooms (up to 1,858 sq ft in one hour) for a complete comfort setup.
Key Features & Benefits
- Two devices in one: Space heater for winter + powerful fan for summer.
- Jet Focus Control™: Toggle between focused personal heat and wide room diffusion.
- Thermostat precision: Maintains your target temperature to avoid energy waste.
- Safe, bladeless design: No fast-spinning blades or exposed heating elements.
- Quiet, smooth airflow: Streamlined path reduces turbulence and noise.
- Even distribution: Oscillation spreads warm/cool air consistently.
- Magnetized remote: Curved, stores on top of the unit so it’s always within reach.
In-Depth Analysis & Real-World Use
Unlike seasonal appliances that gather dust half the year, the AM09 earns its keep 12 months out of 12. In winter, the PTC ceramic heater ramps quickly, then holds steady using thermostat feedback. In summer, the fan mode keeps air moving without the buffeting you feel from bladed fans. Households with kids and pets also appreciate the inherently safer, easy-to-clean bladeless construction.

Frequently Asked Questions (FAQ)
Does the Dyson AM09 purify the air?
No. The AM09 is a heater and fan. It doesn’t include HEPA filtration. For purification, add a dedicated air purifier.
Can it replace an AC?
It improves comfort with strong airflow but won’t reduce room temperature like refrigerant-based air conditioning.
Is it safe around children and pets?
Yes—no exposed blades or heating elements, a cool-to-touch body, and tip-over shutoff.
What room size does it suit?
Best for small–medium rooms (about 200–400 sq ft). Larger areas may need zoning or multiple units.
Does it include a remote?
Yes. The curved, magnetized remote snaps onto the unit for storage.
Buyer’s Guide: Choosing a Heater–Fan (and When to Add a Purifier)
To pick the right comfort setup, consider the following:
- Energy efficiency: Thermostat-based control prevents overshoot and wasted energy.
- Safety: Tip-over shutoff, bladeless design, and cool-to-touch surfaces reduce risk.
- Year-round utility: A heat + fan combo like the AM09 maximizes use across seasons.
- Room size: Match output to space; avoid underpowered units in large rooms.
- Noise: Bedrooms and offices benefit from smoother, less-turbulent airflow.
If allergies, smoke, or pet dander are concerns, add a purifier with medical-grade HEPA. A smart option is the
Jafända Smart WiFi Air Purifier (H13), which integrates with Alexa to automate schedules around your routine.
Seasonal & Google Trends Insights
Search interest in heaters typically spikes from October through February, while fans and purifiers trend upward in late spring and summer. This makes a dual-purpose device like the AM09 a smart, year-round buy. During allergy season, a purifier such as the
MOOKA H13 True HEPA is a timely pairing.

Final Verdict
The Dyson Hot+Cool Fan Heater AM09 is a premium, safe, and stylish way to control comfort in small–medium spaces. It heats quickly, circulates smoothly, and looks great on display. While it carries a higher price than basic heaters, its 365-day usefulness and Dyson engineering tip the value equation in its favor.
For the most complete setup, many readers pair the AM09 with a high-efficiency purifier like
InvisiClean Bella (H13 Medical-Grade)—clean air + perfect temperature.
