Dyson Hot+Cool: Is It Worth It? (2026)
The short version: No, if what you want is heat. Yes, if what you want is a year-round appliance you will actually keep out. Every Dyson here is a 1500W electric heater, exactly as powerful as a $40 ceramic heater from a big-box store. Physics does not care about design. What the premium buys is a quiet, child-safe, bladeless tower that heats in winter, moves air in summer, and (on the two purifier models) filters the air all year, so it never has to go into a closet. If that package solves a real problem in your home, the Dyson Purifier Hot+Cool HP2 De-NOx (~$700) is the one to get. If you only need heat and airflow, the Dyson Hot+Cool AM09 (~$300 on sale) is the saner Dyson. Below is the honest breakdown of what each costs, what each does, and who should buy (or skip) each one.
How this guide works: we don't run a test lab, and nothing below is a reprinted review. We've read the published verdicts from review outlets, and synthesized them in our own words (key findings, and where the sources agree or disagree), with links to the originals. See "How we compiled this" below for the full method.
The prices
| Typical price | What it does | |
|---|---|---|
| Dyson Purifier Hot+Cool HP2 De-NOx | ~$700-$750 | Heater + fan + purifier (NO2 and formaldehyde capture) |
| Dyson Purifier Hot+Cool HP07 | ~$600 | Heater + fan + purifier (HEPA H13) |
| Dyson Hot+Cool AM09 Jet Focus | ~$300-$350 (lists at $499.99) | Heater + fan only, no purifier |
| The budget combo | ~$40 ceramic heater + ~$100-$150 purifier | Same jobs, separate boxes |
Typical street prices, September 2026. The AM09 routinely discounts to around $300 (TechRadar and TechAdvisor both flagged the $299-$300 street price); the HP2 De-NOx sat at $700-$750 against a $949.99 list (Best Buy, Apartment Therapy).
How we compiled this
We synthesize verdicts from named review sources; we don't reprint their text. For this guide we consulted Apartment Therapy (HP2 De-NOx hands-on review), TechAdvisor and TechRadar (AM09), Tom's Guide, Android Authority, and Digit (HP07 and its predecessors), HomeWiseReview (HP2 De-NOx, 4.4/5), plus aggregated owner ratings from Best Buy (HP2 De-NOx: 4.7 from 57 reviews; AM09: owners satisfied on heating and quiet, price the main complaint) and Dyson's own reviews pages.
Each product section names which outlets covered that model, with their verdict summarized in our own words and linked to the original page. Where the sources disagree, or where owners report something the labs didn't catch, we say so instead of smoothing it over. Coverage isn't uniform: we couldn't verify current 2026 Hot+Cool coverage from Wirecutter, RTINGS, or CNET, and we note that gap rather than filling it in. Note that Dyson is replacing the HP07 with the HP2 De-NOx: Dyson's own HP07 page is currently out of stock and points buyers at "our latest purifier technology," so treat the HP07 as the outgoing model.
Dyson Purifier Hot+Cool HP2 De-NOx: The flagship
This is Dyson's current flagship Hot+Cool, and the only one of the three with gas-phase chemistry worth talking about: sealed HEPA H13 filtration, a potassium-enriched carbon filter that Dyson says captures 50% more nitrogen dioxide than its older filters, and a catalytic filter that continuously destroys formaldehyde. It heats, it blows cooling airflow (not air conditioning, a fan, just a very good one), and it purifies, with an LCD screen showing live pollutant readings and app control through the MyDyson app.
The reviews split exactly where you'd expect. Apartment Therapy's hands-on reviewer loved it as a year-round appliance: cooling was "clutch on hot summer days," filtration ran "around the clock," and the selling point that mattered most was never having to store it (review). HomeWiseReview gave it 4.4/5, with its strongest marks for gas and odor control (4.8/5) and its weakest for value for money (3.9/5) (review). Best Buy owners rate it 4.7 out of 5 across 57 reviews, with heating performance the most-mentioned praise (reviews).
The dissent is worth hearing: one verified owner on Dyson's own site rated it 3/5 specifically because the cooling airflow disappointed him, even at maximum speed, he bought it partly for the breeze and found it weaker than the price promised. HomeWiseReview's verdict lands in the same place: best suited to bedrooms and small spaces, and outperformed per dollar by dedicated purifiers if you don't need the heating.
Best for: anyone who wants one appliance doing heat, airflow, and real purification year-round, especially in a bedroom or home office; city apartments and gas-cooking households that care about NO2 and formaldehyde.
Not for: large open rooms (multiple sources say it's a small-space machine), or anyone who already owns a good purifier and a good heater.
Dyson Purifier Hot+Cool HP07: The outgoing middle child
The HP07 does everything the HP2 does except the De-NOx chemistry: sealed HEPA H13, heat, cooling airflow, app and voice control, real-time air-quality readings on its LCD. Tom's Guide praised its "top notch heating" and even room warming while flagging the price and the annoyance that heating can only be operated from the remote (review). Android Authority's reviewer came away "convinced that the premium price point is worth it," mostly on the strength of the all-in-one design (review). Digit gave the Hot+Cool purifier line 8/10, with value for money the weakest category (review).
The honest positioning: the HP07 is the same three-in-one package minus the NO2 and formaldehyde upgrades, at roughly $100 less on the street. But it's the outgoing model, Dyson's own page pushes buyers toward the HP2, and stock is spotty. It makes sense at a discount; at near-HP2 pricing, it doesn't.
Best for: deal hunters who find it clearly under the HP2's price and want the three-in-one package without paying for gas-phase filtration they don't need.
Not for: anyone paying full price, where the HP2's formaldehyde and NO2 upgrades cost little extra.
Dyson Hot+Cool AM09: The heater and fan, nothing else
The AM09 is the purifier-less one: a bladeless heater with thermostatic control and a cooling-fan mode, Jet Focus (a narrow stream for personal heating) and Diffused (wide projection) airflow modes, and a magnetized remote. No filters to replace, no app, no air-quality readings.
It's also the only Dyson here whose reviews almost unanimously say "buy it on sale." TechAdvisor noted it lists at $499 but is "readily available for a more approachable $299," calling it a solid option "if you want a Dyson rather than a dupe" (review). TechRadar gave the full review 4.5 stars and kept flagging the $299 deal price as the buy point (review). DigitalTrends called it "a strong value" at $299.99 for "a year-round comfort appliance that replaces both a space heater and a fan" (deal writeup). Best Buy owners are satisfied with heating performance and quiet operation, with price as the recurring complaint (reviews).
The physics caveat, repeated across owner forums: all electric heaters are 100% efficient, so the AM09 heats no better than a $40 ceramic heater, it's quieter, safer around kids (no blades, no exposed elements, tip-over shutoff), and it stays out all year. That's the entire pitch, and owners seem to understand the deal: Best Buy's reviewers call it "pricey but valuable."
Best for: bedrooms and offices where you want one quiet, kid-safe unit doing heat in winter and airflow in summer, at the ~$300 sale price.
Not for: anyone who needs purification (it has none), or anyone paying the full $499.99 list.
Head-to-head: the dimensions that matter
What the premium actually buys. Not heat output: all three are 1500W heaters, and forum threads (like this long ozbargain debate) make the physics point bluntly, "strictly speaking all heaters are 100% efficient," the Dyson "works similarly to a cheaper model, but I like the sleek design." What you're paying for is: bladeless safety (no hot surfaces, no blades, the #1 owner-cited reason in Best Buy reviews), quiet airflow, a thermostat that actually holds a temperature instead of blasting until you switch it off, and year-round utility that eliminates the seasonal storage shuffle. The two purifier models add the MyDyson app with live air-quality data, and the HP2 adds the NO2 and formaldehyde chemistry.
The budget combo keeps up on function. A ~$40 ceramic heater heats just as well as any of these. A ~$100-$150 HEPA purifier (a Levoit Core 300-P class machine) filters a bedroom at least as fast as the HP2's purifier, and replacement filters are cheaper. The combo costs ~$150-$200 total and matches the HP2's three jobs. What it doesn't match: one footprint, one device to live with, no blades, and gas-phase (formaldehyde/NO2) filtration, which budget purifiers don't do.
Running costs favor nobody. In heater mode each draws ~1.5 kW, so at typical US electricity rates that's roughly $0.30-$0.60 per hour of heating (one Best Buy owner estimated closer to $1/hr, consistent with high California rates). Fan-only mode is cheap. And the purifier models carry filter replacements: budget roughly $70-$100 a year for the Dyson filter, which the reviews we consulted note as a real ongoing cost.
HP2 vs HP07 vs AM09, in one line each. The HP2 is the flagship: heat, fan, purifier, plus NO2 and formaldehyde chemistry. The HP07 is the same three jobs without the gas-phase upgrades, at ~$100 less, and it's being phased out. The AM09 is just heat and fan in a smaller, quieter tower, and it's the only one worth considering under $350.
Who should buy each one
- Get the HP2 De-NOx if: you want one device that heats, cools, and genuinely purifies year-round, and you have a bedroom or office where air quality matters (city air, gas cooking, new furniture off-gassing formaldehyde). Check the HP2 De-NOx price
- Get the HP07 if: you find it at a real discount under the HP2 and don't care about NO2 or formaldehyde specifically. Check the HP07 price
- Get the AM09 if: you want the Dyson heat-and-fan experience, kid-safe and quiet, with no purifier and no filters to buy, at the ~$300 sale price. Check the AM09 price
- Buy the budget combo instead if: you need heat and clean air but don't need them in the same tower. A ~$40 ceramic heater plus a ~$120 HEPA purifier does the jobs for a fifth of the HP2's price.
Frequently asked questions
Does a Dyson heater actually heat better than a cheap heater?
No. Electric resistance heat is 100% efficient regardless of the box: 1500W in, 1500W of heat out. The Dyson's advantages are even heat distribution (the Air Multiplier projection), a real thermostat that cycles to hold a target temperature, quieter operation, and bladeless safety. It heats more pleasantly, not more powerfully.
Does the cooling mode actually cool a room?
No. There's no refrigerant and no heat exchange; it's a fan moving air across your skin, which feels cooling on you but doesn't lower the room temperature. Dyson's own fine print says "cools you," not "cools your room." Reviewers like it for personal cooling in summer, not as an AC substitute.
What is the HP2 De-NOx's edge over the HP07?
Two things: a potassium-enriched carbon filter Dyson says captures 50% more nitrogen dioxide (NO2, the gas from gas stoves and traffic), and a catalytic filter that continuously destroys formaldehyde (a common indoor VOC from furniture and finishes). The HP07 has sealed HEPA H13 particle filtration but neither of those gas-phase features.
How much does it cost to run?
In heater mode, all three pull ~1.5 kW, so figure $0.30-$0.60 per hour of active heating at typical US rates (more in high-rate states). Fan-only and purifier-only modes are cheap. The purifier models add replacement filters roughly once a year, budget $70-$100.
Is it safe around kids and pets?
This is the strongest objective argument for the Dyson: no exposed blades, no visibly hot heating elements, and automatic shutoff if tipped over. The AM09 and HP2 De-NOx both carry this design, and Best Buy owner reviews cite blade safety for kids as a top reason to buy.
Why is the HP07 hard to find at Dyson?
Dyson is replacing it with the HP2 De-NOx. Dyson's own HP07 page shows it out of stock and points buyers at "our latest purifier technology." Retailers still have stock at discounted prices, which is the only time the HP07 makes sense.
Our recommendations
- The one we'd buy: the Dyson Purifier Hot+Cool HP2 De-NOx (~$700-$750). It's the flagship for a reason: the only model with formaldehyde and NO2 filtration, the best reviews, and the full year-round package.
- The value Dyson: the AM09 at ~$300. Never pay list price; at $300 it's a genuinely good heater-fan for a bedroom or office.
- The deal-hunter's play: the HP07 only if you find it well under the HP2.
- The honest answer: if you need heat and clean air and don't care about the tower, buy a ~$40 ceramic heater and a ~$120 purifier. The Dyson's premium is real, but it's for design, safety, quiet, and consolidation, not raw performance.
