Dyson Purifier Hot+Cool Gen1 HP10 - Purifying Fan Heater

I set the HP10 in the corner of my living room during the first chilly snap of fall, and it hasn’t moved since. It’s become a quiet constant: warming the space in the morning, pushing a clean-feeling breeze in the afternoon, and ticking along almost imperceptibly at night. Dyson’s pitch for this model is simple—purify, heat, and cool in one footprint—and in practice it mostly delivers on that promise without fuss.

Setup and design

Out of the box, the HP10 looks like a restrained take on Dyson’s bladeless design. The oval loop is familiar, the base is compact, and the whole unit is easy to place where a traditional space heater would feel awkward. The build feels tight and well-finished, and the small display at the base communicates what you need without shouting. A nice touch: the curved, magnetized remote that parks neatly on top. It’s the kind of detail that keeps the remote from disappearing in sofa cushions.

Setup was quick. The filters are pre-installed, the unit is already sealed to HEPA standard, and there’s no app pairing to wrestle with—because there’s no app at all. If you want graphs, automations, or air-quality history, this is not the model for you. Personally, I appreciated the simplicity. Power, mode, temperature, fan speed, oscillation, and a sleep timer are all a button press away.

Heating performance

As a heater, the HP10 is surprisingly capable. The thermostat control is straightforward: set your target temperature and the unit ramps up quickly, then eases off as it reaches your set point. I used it to take the edge off a 250-square-foot bedroom on frosty mornings and to keep a drafty home office comfortable without cranking the whole-house system. Warmth is even, not scorching, and the Air Multiplier design avoids that “toasting your shins while your back is freezing” effect you get with many space heaters.

Oscillation is the secret weapon here. With up to 350 degrees of coverage, I could park the HP10 in a corner and still sweep warmth around most of the room. If you’ve struggled to place a heater in tight or open-concept spaces, the near full-circle swing is genuinely useful.

As with any electric resistance heater, you’ll feel the energy draw when heating. It’s meant for spot and room-level warmth, not replacing central heat. Used that way, it’s efficient enough.

Cooling and airflow

Dyson’s “cool” mode is about airflow, not air conditioning. There’s no refrigeration happening. That said, air movement goes a long way in stuffy rooms, and the HP10 does a good job here. The stream is smooth and comfortable rather than gusty, and the fan speeds have enough range to go from barely-there circulation to a focused breeze across the room.

Because it oscillates so widely, it can keep multiple seating positions feeling fresher without pointing a jet at anyone’s face. If you want a true chill, you’ll still need AC, but for everyday comfort the airflow feels premium compared to a box fan.

Air purification

Purification is this model’s through line across all seasons. The HP10 is fully sealed to HEPA standard, which matters more than headline filtration numbers: sealing ensures that air actually passes through the filter media instead of leaking around it. In my home, that translated to fewer lingering cooking smells and less morning stuffiness during pollen-heavy weeks.

This unit doesn’t drown you in metrics. There’s no app dashboard, and the on-device display stays minimal. Instead, you’ll notice the difference in how the room smells and feels over time. I’d still love to see at least a particle indicator on the display for quick, at-a-glance reassurance, but the “it just runs” approach has its own appeal.

Noise and night mode

The HP10’s sound profile is calm. At low to mid fan speeds in purification or cooling mode, it fades into the background. If you sleep better with a prominent hum or “whoosh,” this likely won’t scratch the white-noise itch unless you crank the fan up. Night mode helps by dimming the display and biasing toward quieter settings, and I had no trouble sleeping with it a few feet from the bed.

Heat mode is a touch louder at startup as it ramps, then it settles. There were no rattles or buzzes from my unit; if you do hear something odd, reseating the filter and checking the base on a level surface is worth two minutes of troubleshooting.

Controls and everyday use

Everything runs through the remote, which is intuitive: big temperature buttons, clear mode toggles, and separate controls for oscillation and a programmable shutoff (1, 2, 4, or 8 hours). The magnetized storage works exactly as intended; you learn to drop the remote on top as muscle memory.

The lack of Wi-Fi is a double-edged sword. On the plus side, setup is instant, there are no app permissions to agree to, and guests can figure it out without training. On the minus side, you can’t schedule it by time of day, query air quality from your phone, or tie it into a smart home routine. I didn’t miss those features in a bedroom, but I wished for them in the office, where automations are handy.

Coverage and placement

Dyson doesn’t plaster room-size claims everywhere, which is probably wise given ceiling heights and layouts vary wildly. In my testing, the HP10 handled a typical bedroom easily and made a meaningful dent in an open living/kitchen space—especially with the 350-degree sweep engaged. Placement flexibility is excellent. Corner, against a wall, midway between zones—the near wraparound oscillation makes it easy to share the output across multiple areas.

If you’re trying to purify or warm a very large great room alone, you’ll want realistic expectations: it’s a single unit, not a whole-home system. But for the spaces most people inhabit day to day, the balance of airflow and purification feels well judged.

Maintenance and filters

Filter access is simple and tool-free. The unit is sealed, which keeps captured particles inside where they belong, and the replacement process doesn’t create a dust cloud. Replacement frequency will depend on use and local air quality. If you run it hard during wildfire season or peak pollen, plan on more frequent changes. Dyson’s proprietary filters aren’t the cheapest on the market, but they are easy to find and the convenience is real.

I’d love a clearer on-device reminder for filter status in addition to the usual indicator, and a printed quick-start guide wouldn’t hurt for households that dislike QR-code manuals.

What I like

• Quiet, smooth airflow that works across seasons
• Effective heating with accurate temperature hold
• Wide 350-degree oscillation that makes placement flexible
• Fully sealed HEPA design inspires confidence
• Thoughtful touches: magnetized remote, night mode, simple sleep timer
• No app setup or account required

What I don’t

• No smart features or app control for scheduling and insights
• Minimal on-device feedback about air quality
• Replacement filters add to long-term cost
• If you prefer strong white noise, you may find it too quiet at comfortable settings

The bottom line

The HP10 is the kind of appliance you stop thinking about because it just does the job. It quietly improves comfort and air quality without dominating a room or your attention. If you need deep smart-home integration, a loud white-noise fan, or the lowest possible operating costs, this isn’t your match. But if you value calm operation, effective heating, and credible purification in one tidy package, it’s easy to appreciate what Dyson has built here.

Recommendation: I recommend the HP10 to anyone who wants a single, well-designed unit to purify and condition the air in bedrooms, home offices, and medium-size living spaces—especially if you prefer a simple remote-led experience over app control. It’s not the cheapest path to cleaner air or the most feature-laden heater, but the combination of quiet performance, wide oscillation, and sealed HEPA filtration makes it a dependable, year-round upgrade.
