Dyson AM09 Review: Hot+Cool Jet Focus Fan Heater Tested?

Looking for a single device that heats your room in winter and cools you down in summer? The Dyson AM09 Hot+Cool Jet Focus promises to do both. This bladeless fan heater grabbed attention with its sleek look, smart engineering, and Dyson’s signature Air Multiplier technology.

But is it worth the price tag? I tested this unit across multiple rooms, different seasons, and a range of settings. In this honest review, I share what works, what does not, and who should actually buy it.

You will learn about the design, heating speed, cooling power, noise levels, energy use, safety features, and how it compares to other top picks. By the end, you will know if the AM09 fits your home or if a cheaper option works better for you.

Let us get straight into the details.

Key Takeaways: Dyson AM09 At a Glance

Before we go deep, here is a quick summary of what you need to know about the Dyson AM09.

• Two devices in one: The AM09 works as a fan heater in winter and a cooling fan in summer, saving you space and money on separate appliances.
• Jet Focus technology: You can switch between focused airflow for personal warmth or diffused airflow to heat a whole room evenly.
• Bladeless and child safe: No fast spinning blades and no visible heating elements make it safer around kids and pets.
• Quiet operation: The AM09 runs around 75% quieter than its older sibling, the AM05, thanks to acoustic upgrades.
• Premium price: At close to $499, this unit costs much more than standard space heaters, but it bundles cooling, design, and safety in one package.
• Energy efficient heating: The thermostat shuts off the heater once your target temperature is reached, which helps trim power bills.

What Is the Dyson AM09 Hot+Cool Jet Focus?

The Dyson AM09 is a bladeless fan that heats and cools. It uses Air Multiplier technology to draw in surrounding air and push out a strong, steady stream through its oval loop. There are no fast spinning blades, which makes it safe to touch.

In winter, ceramic plates inside the base warm the air quickly. In summer, those plates switch off and the device acts as a powerful tower fan. You get two seasons of use from a single product.

The “Jet Focus” name refers to its special airflow modes. You can pick focused mode for a long, narrow stream of air that warms or cools one person. Or you can switch to diffused mode for a wider spread that fills the whole room.

The AM09 stands about 23 inches tall and weighs only 5.9 pounds. It comes with a magnetic remote that snaps to the top of the unit so you do not lose it. You can adjust temperature, oscillation, airflow strength, and a sleep timer with the remote.

This model has been a Dyson favorite for years. It still holds up because it does the basics well and looks great while doing them.

Design and Build Quality

The AM09 looks like a piece of modern art. Its smooth oval loop sits on a short cylinder base. The white and silver finish or the black and nickel finish fits most living rooms, bedrooms, and offices.

Build quality feels solid. The plastic is thick and the controls click with a satisfying tap. The unit does not wobble, even at full power. Dyson clearly engineered this product to last.

It only weighs about 5.9 pounds, so you can carry it from room to room without effort. The base has a small handle cut into it, which makes lifting easy.

The magnetic remote is a small touch that I really appreciate. It sticks to the top of the loop so you always know where it is. No more digging through couch cushions in the middle of winter.

There is no display on the unit itself. The remote handles all the inputs. Some people might miss a touch screen or app control. If smart features matter to you, the AM09 will feel a bit basic.

But for buyers who want a clean, minimal device that just works, the design is hard to beat. It looks expensive because it is expensive.

Heating Performance and Jet Focus Mode

The AM09 heats fast. Its 1500 watt ceramic heater can warm a small to medium room within minutes. I tested it in a 200 square foot bedroom and it reached a comfortable 72°F from a chilly 60°F in under 15 minutes.

You set your target temperature between 33°F and 99°F. The unit then runs at full power until it hits your goal. After that, it cycles on and off to hold the temperature steady. This stops wasted energy and keeps the room from getting too hot.

Jet Focus is the killer feature here. In focused mode, the air streams out in a tight column. This is great when you sit at a desk and want warm air pointed right at you. The reach is about 30 feet.

Switch to diffused mode and the air spreads wide. This works best when you want to heat a whole room evenly. The oscillation feature swings the unit up to 70 degrees side to side.

The AM09 is best for small to medium spaces. It will struggle to heat a large open living room on its own. For bedrooms, home offices, and dens, it performs very well.

Cooling Performance in Summer

When summer hits, the AM09 turns into a powerful tower fan. The heating element shuts off and only the airflow stays. You still get the focused and diffused modes.

In cooling mode, the AM09 pushes out a strong, smooth stream of unheated air. It does not produce cold air like an air conditioner. It simply moves room temperature air across your skin to make you feel cooler.

I found it works great as a personal fan or to boost airflow in a stuffy room. Aim it at your bed at night and you sleep cooler. Point it across the room and it stirs up stagnant air fast.

The 10 airflow settings give you fine control. Setting 1 is barely a whisper. Setting 10 is strong enough to rustle papers across the room. Most people will live in the 3 to 6 range for daily comfort.

It does not replace an air conditioner in hot climates. But it does replace a regular tower fan, and it does so with style. The bladeless design also makes it easier to clean than a traditional fan with grills and blades.

For year round use, having one device for both seasons is a real win.

Top 3 Alternatives for the Dyson AM09

If the Dyson AM09 feels too pricey or you want different features, here are three solid options worth a look. Each one targets a slightly different buyer.

No products found.

No products found.

The Dyson HP07 adds an air purifier with a HEPA filter to the same hot and cool function. If you want clean air plus heating and cooling in one unit, it is the natural upgrade. The Vornado AVH10 offers strong whole room heating at a much lower price, though it uses traditional blades. The Lasko Ceramic Tower Heater is a budget pick that still gives you oscillation and a remote, just without the Dyson polish.

Noise Levels and Sleep Use

Dyson redesigned the AM09 to be 75% quieter than the older AM05. That claim holds up in real use. On low settings, the unit is almost silent. You can sleep right next to it without trouble.

On medium settings, you get a soft white noise hum. Many users actually find this sound helps them fall asleep. On the highest settings, it gets noticeably louder, but never harsh or whiny.

The sleep timer is a nice touch. You can set it to shut off after 15 minutes, 30 minutes, 45 minutes, or up to 9 hours. I usually set mine for 2 hours so it warms the bedroom and then turns off after I fall asleep.

There are no bright LEDs that disturb sleep. The small status light on the base is dim and unobtrusive. You can also dim it further if needed.

If you are a light sleeper, the AM09 is one of the few heaters I would recommend without hesitation. Most cheap space heaters have loud fans or noisy clicking thermostats. This one does not.

For nurseries or kids’ rooms, the quiet operation plus the bladeless safety design makes it a strong pick.

Safety Features You Should Know About

The Dyson AM09 was built with safety at the front of mind. There are no fast spinning blades to catch fingers or hair. There are no exposed heating elements that could burn skin on contact.

If the unit tips over, it shuts off automatically. This tip over protection is critical in homes with kids or pets. I tested it by nudging the unit and it powered down right away.

The outer surface stays cool to the touch even when the heater runs at full power. You can brush against it without burning yourself. This is one reason parents like it for nurseries.

The AM09 also has automatic shut off when it reaches the set temperature. It will not keep heating endlessly and overheat the room. This protects against fires from forgotten heaters left running.

There is no open flame, no fuel, and no carbon monoxide risk. It runs on standard 120V household power.

Dyson backs the unit with a 2 year warranty that covers parts and labor. While some users report issues after the warranty ends, most owners get years of trouble free use. Keeping the air intake clean helps extend the life of the device.

Energy Use and Running Costs

The AM09 draws 1500 watts on full heat. That is standard for an electric space heater. It does not use less power than a basic heater while warming up.

Where it saves you money is in the smart thermostat. The unit shuts off the heater once your target temperature is reached. Cheaper heaters often run full blast nonstop, which wastes electricity.

In a typical 200 square foot room, the AM09 only runs at full heat for about 15 to 20 minutes per hour. After that, it cycles in short bursts to hold the temperature. This can cut your running costs by 30% or more compared to a dumb heater.

To estimate your monthly cost, multiply 1.5 kilowatts by your hours of use per day, then by your electricity rate. For example, 4 hours of daily use at 15 cents per kWh works out to about $27 a month. Real usage with the thermostat cycling will likely be less.

Compared to central heating a whole house, using the AM09 only in the room you occupy can save you a lot. This is sometimes called “zone heating.”

For cooling, the AM09 uses far less power, around 26 to 56 watts depending on fan speed. That is much cheaper than running an air conditioner.

Remote Control and Ease of Use

The included magnetic remote is one of the AM09’s best features. It controls everything: power, temperature, oscillation, airflow strength, sleep timer, and focus mode.

The remote sticks to the top of the loop with magnets. You will never lose it as long as you put it back. It runs on a single CR2032 coin battery that lasts about a year.

Setting up the unit is simple. You plug it in, press the power button, and pick your temperature with the remote. There are no apps to install, no Wi-Fi to set up, and no settings to configure. It just works.

This simplicity is both a strength and a weakness. If you love smart home features, the AM09 will feel dated. It does not connect to Alexa, Google Home, or Apple HomeKit. The newer Dyson HP07 fills that gap if you want app control.

But many buyers prefer the no nonsense approach. You do not need a software update to turn on your heater.

The interface is friendly for older users or anyone who finds smart devices confusing. Big buttons, clear labels, and instant response make it easy for everyone in the family to use.

Maintenance and Cleaning

The AM09 is one of the easiest heaters to keep clean. The bladeless design means there are no fan blades or cage grills where dust collects.

To clean it, just wipe the outside with a soft, dry cloth. For the air intake holes at the base, use a soft brush or a vacuum with a brush attachment. Do this once a month for best performance.

Never use water or cleaning sprays inside the unit. Liquid can damage the heating element and electrical parts. The outer surface only needs a damp cloth if it gets dirty.

There is no filter to replace on the AM09. This saves you ongoing costs. If you want filtered air, you need to step up to the HP07 or another purifier model.

Dust buildup on the intake is the main thing to watch. If you let it clog, airflow drops and the unit works harder. A quick monthly cleaning keeps it humming along.

Store the unit in a dry place when not in use. The light weight makes it easy to tuck into a closet during off seasons, although many owners just leave it out year round because it looks good.

Who Should Buy the Dyson AM09?

The Dyson AM09 is not for everyone. Here is who will get the most value from it.

Small to medium room owners: If you want to heat or cool a bedroom, home office, or den, the AM09 shines. It struggles with very large open spaces.

Families with kids or pets: The bladeless design, cool exterior, and tip over shut off make it one of the safest space heaters available.

Design conscious buyers: If you care about how your appliances look, few products compare. The AM09 looks great in any modern home.

Year round users: Buying one device that does two jobs saves storage space and money. You skip buying a separate heater and fan.

Light sleepers: The quiet operation makes it bedroom friendly. Most cheap heaters are too noisy for sleep.

Who should skip it? Buyers on a tight budget. You can get a basic Vornado or Lasko heater for under $100 that does the heating job well, just without the looks or the cooling mode. Also, if you need to heat a whole open floor plan, the AM09 will not cut it.

Pros and Cons of the Dyson AM09

Let us break down the AM09 honestly. Every product has trade offs.

The pros include excellent safety thanks to the bladeless and cool exterior design. The dual heating and cooling function gives you year round value. Jet Focus mode lets you target one person or fill a whole room. The quiet operation is a big plus for sleep and offices. The magnetic remote is a smart touch that prevents loss. The build quality feels premium and the unit looks great in any space.

The cons start with the price. At nearly $500, the AM09 costs five times what a basic heater costs. There is no air purification, so if you want clean air, you need the HP07 instead. There are no smart features and no app control. Some users have reported H2 error codes or heating failures after 2 to 3 years, though others have units that run for many years without issues. The heating power is also limited to 1500 watts, which is plenty for small rooms but not for big spaces.

Overall, the pros outweigh the cons if you can afford it and want a premium experience. The cons matter most if you need budget value or whole home heating.

Final Verdict on the Dyson AM09

The Dyson AM09 Hot+Cool Jet Focus is a premium device that earns its price for the right buyer. It heats fast, cools well, looks great, runs quietly, and keeps your family safe.

It is not the cheapest heater, and it is not the most powerful. But it is one of the most thoughtfully designed home appliances you can buy. For small to medium rooms, it is hard to beat.

If you have the budget and you want one device that handles both winter and summer comfort, the AM09 is a strong pick. If you want clean air on top of heating and cooling, step up to the HP07. If you just want a basic heater, save your money and grab a Vornado or Lasko.

I give the Dyson AM09 a solid 4.5 out of 5 stars. It loses half a star only because of the high price and the lack of smart features. Everything else about it impresses me.

After several months of testing, it has earned a permanent spot in my home office. I use it nearly every day from October through April for heat, and from June through August as a fan. That kind of year round use is rare for a single appliance.

If you can stretch the budget, you will not regret this purchase.

How big a room can the Dyson AM09 heat?

The AM09 works best in small to medium rooms up to about 200 to 300 square feet. It can heat larger spaces but will take longer and may not maintain temperature in big open areas. For bedrooms, home offices, and dens, it performs very well.

Does the Dyson AM09 have an air purifier?

No, the AM09 does not purify the air. It only heats and cools. If you want air purification along with heating and cooling, look at the Dyson HP07 or newer purifier models. They include HEPA filters and activated carbon to capture pollutants.

Can I control the Dyson AM09 with my phone?

No. The AM09 does not support Wi-Fi, Bluetooth, or app control. It only works with the included magnetic remote. If you want smart home integration, the Dyson HP07 supports the Dyson Link app, Alexa, and Google Home.

How long does the Dyson AM09 last?

Most owners get 5 or more years of regular use from the AM09. Some units have lasted over a decade. Dyson backs the unit with a 2 year warranty. Cleaning the air intake regularly and avoiding heavy dust environments helps extend its life.

Is the Dyson AM09 worth the price?

It depends on your needs. If you want premium design, year round use, top tier safety, and quiet operation, yes, the AM09 is worth it. If you only need basic heating for one season and budget matters most, a $50 to $100 heater will do the job for less money.
