You've seen them. Those sleek, loop-shaped pillars standing in the corner of a high-end living room or a tech-obsessed office. They look like they're from 2045, and honestly, they're priced like it too. But if you’re looking for a Dyson cooling and heating fan, you’ve probably realized the marketing is a bit of a maze.
Is it an air conditioner? No. Is it a space heater? Kinda, but it's a lot smarter than that rusty coil unit in your garage.
The truth is, Dyson doesn't really make "fans" anymore. They make "Purifiers" that happen to move air. If you're walking into a store looking for the latest model in 2026, you're looking at the Dyson Purifier Hot+Cool series (the HP models). These machines try to solve three problems at once: staying warm in January, staying cool in July, and not breathing in pet dander every single day in between.
The Magic (and Physics) of Air Multiplier Tech
Most fans use blades to chop the air. It’s "buffety" and feels like being slapped by a tiny wind-god. Dyson uses something called Air Multiplier technology. Basically, air is sucked into the base, accelerated through a tiny slit in the loop, and then it drags the surrounding air along with it.
It’s the same principle used in jet engines.
When you switch it to heat mode, the air passes over PTC ceramic plates. These plates are self-regulating, meaning they won't get hotter than 180°C. Why does that matter? Because it's below the burning point of dust. You won't get that "toasted dust" smell that usually happens when you turn on a cheap heater for the first time in winter.

What about the "Cooling" part?
Here is where people get annoyed. A Dyson cooling and heating fan is not an air conditioner. It does not have a compressor. It does not use refrigerant. It won't turn a 90-degree room into a 65-degree oasis.
It's a high-velocity fan. It cools you via evaporation on your skin. If you go into it expecting a portable AC, you’re going to be disappointed. But if you want a stream of purified air that feels significantly smoother than a $20 box fan, this is the gold standard.
Choosing Your Machine: HP07 vs HP09 vs Gen1
Dyson loves confusing names. Currently, the lineup basically breaks down into how much you care about "forever chemicals" and noise.
- Dyson Purifier Hot+Cool Gen1 (HP10): This is the "budget" entry (if you can call $500 budget). It has the HEPA filtration and the heating/cooling, but it lacks the fancy formaldehyde destruction.
- Dyson Purifier Hot+Cool (HP07): The classic. It’s fully sealed to HEPA H13 standards. This is a big deal because it means the "bad stuff" doesn't leak out of the machine's cracks before it hits the filter.
- Dyson Purifier Hot+Cool Formaldehyde (HP09): This has a gold-tinted base and a specialized catalytic filter. It literally breaks down formaldehyde (found in cheap furniture and carpets) into water and CO2. The best part? That specific filter never needs to be replaced.
Honestly, unless you just renovated your house with new flooring or cabinetry, the HP07 is usually the sweet spot for most people.
The Real Cost of Ownership
Let's talk money. You aren't just paying for the machine; you're paying for the filters.
Most Dyson filters need replacing every 12 months if you're running them 12 hours a day. In 2026, a genuine replacement filter will set you back about $75 to $100. There are third-party filters on Amazon, sure, but if they don't have the same "seal," you’re basically just blowing dust around the room.
Energy usage is another thing to watch.
- In fan mode, these things are incredibly efficient, drawing maybe 40-50 watts at max speed.
- In heat mode, they pull about 1,500 to 2,000 watts.
That’s a lot. It’s the same as any other space heater. Physics is physics—to heat air, you need power. However, because of the built-in thermostat, it’ll click off the second the room hits your target temp, which saves a bit of cash compared to a "dumb" heater that just stays on until you smell smoke.
Is It Actually Quiet?
Dyson claims these are "20% quieter" than previous generations. In my experience, at speeds 1 through 4, you won't even know it's on. It’s a whisper.
Once you crank it to 10? Yeah, it sounds like a small turbine. But it’s a "clean" white noise, not a mechanical rattle. If you’re using it in a bedroom, the Night Mode is a lifesaver. It dims the LCD display and caps the fan speed so you don't feel like you're sleeping on a runway.
Surprising Details Most People Miss
One of the coolest features—and I use "cool" literally here—is the Diffused Mode.

Ever want the air cleaned but don't want a cold breeze hitting you in the face? The machine can actually reverse the airflow, blowing it out the back of the loop. It still purifies the room, but you don't feel the "wind chill." This is a massive win for winter use when you just want the air scrubbed of allergens but don't want to get a cold.
Also, the MyDyson app is surprisingly useful. It gives you a live graph of your air quality. You can see the spike in VOCs (Volatile Organic Compounds) the second you start frying bacon or spraying hairspray. It’s a bit scary to see how "dirty" your indoor air is, but it's satisfying to watch the graph turn from red to green once the fan kicks into high gear.
Actionable Tips for New Owners
- Placement is everything: Don't tuck it in a corner behind a couch. It needs 360-degree intake to work properly. Give it at least a foot of breathing room from the wall.
- Auto Mode is your friend: Don't manually mess with the speeds. Let the sensors do it. It’ll ramp up when it smells smoke and go silent when the air is clean.
- Vacuum the shroud: Every month or so, run a vacuum brush over the little holes at the base. Dust builds up there and makes the motor work harder (and louder).
- Check your seals: If you buy a replacement filter, make sure it’s seated perfectly. If it’s not clicked in, the "fully sealed HEPA" claim goes out the window.
If you’re looking to buy, keep an eye on the HP07. With the newer "Big+Quiet" models taking over the flagship spots, the HP07 often goes on sale for $150 off during holiday cycles. It’s still the best all-rounder Dyson has ever made for a standard-sized bedroom or office.
