Searching for a Dyson air conditioner? One distinction matters before anything else: these products move and purify air, but they are not compressor air conditioners and do not lower a room’s temperature. I’ve ranked them for buyers who want a Dyson-style cooling fan alongside air cleaning, with some models adding heat for year-round use. My leading picks are the HP2 De-NOx for heating, cooling airflow, and enhanced gas filtration; the PC1 for a simpler purifier-and-fan setup; and the HP10 for buyers who want heating and cooling airflow without app-dependent control. The tradeoffs are room coverage, whether heating is useful, filtration needs, and how much you value app features over straightforward remote operation.

Key Takeaways
- Best overall for all-season use: HP2 De-NOx combines fan cooling, heating, app control, and enhanced NO₂ capture; it is the most feature-rich pick, not a substitute for an AC.
- Best for cooling airflow and purification: PC1 skips the heater and offers 350° oscillation, making it a clearer fit if you mainly want a purifier fan.
- Best for targeted gas filtration: PC2 De-NOx adds formaldehyde and gas removal to the cooling-fan role, but the supplied listing gives no floor-area figure.
- Best for straightforward all-season operation: HP10 includes heating, fan airflow, and a remote, while forgoing the app features found on the newer models.
- Check room fit before choosing: listed floor areas range from 73 to 109 square feet where provided, and airflow cooling does not actively chill a room like a compressor AC.

More Details on Our Top Picks
Dyson Purifier Hot+Cool HP2 De-NOx
I rank the HP2 De-NOx first because it is the most complete choice for someone who wants a purifier fan that can also heat. It pairs fan cooling airflow and heating with HEPA H13 filtration, app and remote controls, and the specific claim that it captures 50% more NO₂. Its description also says it removes odors and gases and continuously destroys formaldehyde. That combination gives it a broader role than the PC1, which focuses on purified cooling airflow without a heater.
The stated 109-square-foot floor area is the largest listed figure among the products that provide coverage data here. That gives the HP2 a plausible advantage for a somewhat larger room than the HP1 or HP10, both listed for 73 square feet, though it remains a room-scale device rather than a whole-home solution. Its 36.34-inch height and 12.2-pound weight make it a substantial appliance; buyers in tight rooms should compare its footprint and placement needs with the slimmer PC1 and PC2.
The reason to choose this model over the less expensive-in-feature-set alternatives is its combination of heat and more targeted gas filtration, not the promise of air conditioning. It moves air to provide a cooling sensation but does not actively refrigerate or lower room temperature. App connectivity also adds setup and Wi-Fi dependence for its smart features, while the more basic HP10 sticks to remote control. I’d choose the HP2 when its added filtration and heating have real value; I would skip it if summer cooling is the only goal or if a conventional AC is needed.
Pros:- Combines fan airflow and heating with air purification
- Description claims 50% more NO₂ capture and continuous formaldehyde destruction
- App, remote, and voice control options
- Largest listed floor area among the models with supplied coverage figures
Cons:- Fan airflow does not lower room temperature like a compressor air conditioner
- Large, tall body may be awkward in a small room
- Full smart functionality calls for Wi-Fi and app setup
Best for: Buyers who want one Dyson purifier for fan airflow, supplemental heating, app control, and enhanced NO₂ and formaldehyde-related filtration in a room around its listed 109-square-foot coverage.
Not ideal for: Anyone who needs true air conditioning, wants a compact unit, does not need heating or advanced gas filtration, or prefers not to rely on Wi-Fi for smart features.
- Functions:Air purification, fan airflow, and heating
- Filter:Sealed HEPA H13
- Particle retention:0.3 microns
- Listed floor area:109 square feet
- Controls:App and remote
- Dimensions:6.1 x 8.66 x 36.34 inches
- Weight:12.2 pounds
Our verdict“I’d pick the HP2 De-NOx for the broadest all-season feature set, provided its advanced filtration and heater matter more than a compact design or true AC cooling.”
Dyson Purifier Cool PC1 HEPA Air Purifier Tower Fan
The PC1 is my preferred choice for buyers whose main interest is a purifier fan, not an all-season heater. It combines a sealed HEPA H13 system with Air Multiplier airflow and up to 350° oscillation. Compared with the HP2, it gives up heating and the HP2’s stated NO₂ and formaldehyde emphasis, but that is a sensible trade if a heater would sit unused for most of the year.
Its listed coverage is 101 square feet, slightly below the HP2’s 109 square feet and above the 73-square-foot figures supplied for the HP1 and HP10. The 41.34-inch height makes it taller than those heater models, despite its slim listed depth and width. Buyers should plan for vertical clearance and placement rather than assuming that a tower fan is inconspicuous. The PC1’s ten fan levels make it easier to adjust airflow, though its listed 61.4 dB noise level may be noticeable in a quiet room.
For general particle filtration, the product description specifies capture of 99.97% of microscopic allergens and pollutants, down to 0.3 microns. It also mentions odor capture, but it does not carry the De-NOx label or the targeted gas-removal language provided for the PC2 and HP2. That makes the PC1 a more straightforward cooling-and-purification pick than the PC2 De-NOx, which is more compelling when gas and formaldehyde concerns lead the decision. App and voice controls can add convenience, but full remote monitoring depends on Wi-Fi; the supplied specs also list a remote, so basic operation need not depend on the app.
As with every option here, cooling means moving air across people, not chilling the room. I’d choose the PC1 over a Hot+Cool model when summer airflow and filtration are the priority and I have no use for a heater. I’d pass if I need temperature reduction, quieter operation than the stated noise figure suggests, or more targeted De-NOx filtration.
Pros:- Sealed HEPA H13 filtration with stated 99.97% capture of microscopic pollutants
- Air Multiplier airflow with up to 350° oscillation
- Ten fan levels allow adjustment to personal airflow preferences
- Listed coverage of 101 square feet
Cons:- No heating function
- Listed noise level is 61.4 dB
- Full app and voice features require Wi-Fi
Best for: People who want a tower-style purifier fan with wide oscillation and general HEPA filtration, and do not need a heater.
Not ideal for: Buyers seeking active air conditioning, a heater, targeted De-NOx filtration, or a particularly quiet fan for a sleep-sensitive room.
- Functions:Air purification and fan airflow
- Filter:Sealed HEPA H13
- Particle retention:0.3 microns
- Listed floor area:101 square feet
- Oscillation:Up to 350°
- Noise level:61.4 dB
- Dimensions:4.72 x 8.03 x 41.34 inches
- Controls:Remote; app and voice features described
Our verdict“The PC1 is my pick for purified cooling airflow when a heater would be unnecessary, but it is not a replacement for an air conditioner.”
Dyson Purifier Cool PC2 De-NOx
The PC2 De-NOx suits buyers who want cooling airflow and purification, with more emphasis on gases than the standard PC1. Its description says it captures 99.97% of particles as small as 0.3 microns and removes odors, gases, and formaldehyde. That makes it the clearest cooling-only alternative to the HP2 De-NOx: the PC2 skips the heater, while the HP2 adds year-round warmth and a stated 50% increase in NO₂ capture.
Its product dimensions—4.72 x 8.03 x 41.34 inches—match the PC1 listing, and its 10.8-pound weight is close to the PC1’s 10.5 pounds. Both are tall tower-style devices, so they need more vertical presence than the shorter HP1 and HP10. The PC2 listing does not provide a floor-area figure, unlike the PC1’s 101 square feet. I would not assume the two have identical coverage solely because their dimensions match; buyers who need a stated room-size reference may find the PC1 easier to evaluate.
One advantage over the PC1 is the De-NOx and formaldehyde-focused description, especially for someone prioritizing those contaminant categories. One drawback is that the supplied details do not quantify the NO₂ improvement the way the HP2 description does, nor do they list noise level, fan-level count, or coverage area. I’d compare those missing details against the PC1 before deciding if the extra filtration focus matches your needs. Both models offer app or voice-related smart control through the product description, with a remote listed as the control method; Wi-Fi setup may be needed for connected features.
The PC2 remains a fan and purifier, not an air conditioner. If the chief problem is hot weather and you need a lower indoor temperature, I’d direct you to a conventional AC instead. If your goal is moving purified air without adding a heater, and gas or formaldehyde removal is a leading concern, the PC2 has a more distinct case than the standard PC1.
Pros:- Description includes removal of odors, gases, and formaldehyde
- HEPA filtration with stated capture of particles as small as 0.3 microns
- Cooling airflow without paying attention to an unneeded heater feature
- Remote control and app or voice-connected features are described
Cons:- No floor-area figure is supplied in the product details
- No noise level or oscillation range is listed in the supplied specs
- Does not heat or actively lower room temperature
Best for: Buyers who want cooling airflow without a heater and place particular importance on the product’s stated gas, odor, and formaldehyde removal.
Not ideal for: Anyone who needs heating, a confirmed room-coverage figure before purchase, or actual room-temperature reduction from an air conditioner.
- Functions:Air purification and fan airflow
- Filter:Fully sealed HEPA H13 system
- Particle retention:0.3 microns
- Contaminants described:Odors, gases, and formaldehyde
- Controls:Remote; app and voice features described
- Dimensions:4.72 x 8.03 x 41.34 inches
- Weight:10.8 pounds
- Listed floor area:Not supplied
Our verdict“I’d choose the PC2 De-NOx over the PC1 when gas and formaldehyde filtration matter more than having a published coverage figure or broader listed fan details.”
Dyson Purifier Hot+Cool HP1
The HP1 is a practical middle option for someone who wants one purifier to provide fan airflow in warm weather and heating in cold weather. Its role is similar to the HP2 and HP10, but its supplied coverage figure is 73 square feet, below the HP2’s 109 square feet. The HP1 description emphasizes general allergen and pollutant capture rather than the HP2’s more targeted NO₂ and formaldehyde claims, so I see it as the simpler all-season purifier heater in this lineup.
Its sealed HEPA H13 filter is described as capturing 99.97% of microscopic allergens and pollutants down to 0.3 microns. App and remote controls, plus Air Multiplier airflow, cover the main daily functions. At 30.12 inches tall, the HP1 is shorter than the PC1 and PC2 towers, which may make it easier to place in some rooms. Its listed 63 dB noise level, however, is the highest among the products here that provide a noise figure. That matters if the unit will sit beside a bed, desk, or quiet conversation area.
Compared with the HP10, the HP1 lists app connectivity and a slightly different form factor, while both share a 73-square-foot stated floor area and heater-plus-fan function. The HP10’s supplied noise figure is lower at 59.8 dB, but its control details list a remote rather than app control. I’d favor the HP1 if connected operation matters more than the noise difference; I’d look at the HP10 if a remote-first setup and a lower stated noise figure better match the room.
The central limitation is the same as for the other Dyson fan models: airflow is not refrigeration. This model can circulate air for a cooling sensation and provide heat, but it will not act like a compressor AC during a heat wave. Its listed coverage and noise level also make it less appealing for a larger or especially quiet room. For a smaller room where heating and purification are both useful, it has a balanced role without the HP2’s De-NOx emphasis.
Pros:- Combines air purification, heating, and fan airflow
- Sealed HEPA H13 filter with stated 99.97% particle capture
- App and remote control options
- Shorter listed height than the PC1 and PC2 tower models
Cons:- Listed coverage is 73 square feet
- Listed noise level is 63 dB
- No specific enhanced NO₂ or formaldehyde claim in the supplied description
Best for: Buyers furnishing a smaller room who want a HEPA purifier with both fan airflow and heating, plus app and remote control.
Not ideal for: People who need a larger stated coverage area, quieter operation based on the listed figures, De-NOx-focused filtration, or true air conditioning.
- Functions:Air purification, fan airflow, and heating
- Filter:Sealed HEPA H13
- Particle retention:0.3 microns
- Listed floor area:73 square feet
- Noise level:63 dB
- Controls:App and remote
- Dimensions:5.16 x 8.07 x 30.12 inches
- Weight:11.7 pounds
Our verdict“I’d choose the HP1 for a smaller room where app-controlled heat, fan airflow, and general HEPA filtration matter more than quiet operation or De-NOx features.”
Dyson Purifier Hot+Cool Gen1 HP10
The HP10 is the most straightforward choice for buyers who want a heater, fan, and purifier but do not need app-based monitoring. It captures 99.97% of particles as small as 0.3 microns, provides up to 350° oscillation, and includes a remote and night mode. Compared with the newer HP1, the HP10’s product details emphasize simple remote operation rather than app control; compared with the HP2, it gives up the enhanced NO₂ and formaldehyde claims and the larger listed coverage.
Its stated floor area is 73 square feet, matching the HP1 and placing it below the PC1 and HP2 coverage figures. The listed noise level is 59.8 dB, lower than the HP1’s 63 dB and the PC1’s 61.4 dB, though the figures are supplied without a shared testing method and do not settle how quiet either will sound in your room. Night mode may suit evening use, and 350° oscillation can spread airflow around a room rather than directing it at one spot.
There is a tradeoff in choosing a remote-first model: you avoid relying on an app for routine control, but also miss the app monitoring and connected features described for the newer models. The supplied specifications identify the model year as 2018, so buyers who prioritize newer connected features may prefer the HP1 or HP2. Its dimensions are listed as 9.84 x 9.84 x 30.2 inches, wider than the slim PC tower listings, and its weight is given as 5290 grams. That relatively broad base may affect placement in a crowded room.
I rank the HP10 fifth not because its functions are irrelevant, but because its limited listed coverage and less connected controls make it a narrower match than the newer options. It still makes sense for someone who specifically wants fan airflow, heating, purification, remote control, and night mode in one unit. Like the other products, it does not refrigerate the air. For a buyer expecting a Dyson-branded AC, that limitation is more decisive than any feature on the spec sheet.
Pros:- Combines fan airflow, heating, and HEPA air purification
- Remote control and night mode are included
- Oscillates up to 350°
- Listed noise level is lower than the HP1 and PC1 figures supplied here
Cons:- Listed floor area is 73 square feet
- No app compatibility is listed
- Wider dimensions and an older stated model year may be less appealing to buyers seeking a newer connected design
Best for: Buyers who want a remote-controlled purifier, heater, and fan with night mode and do not need app connectivity.
Not ideal for: Those who want smart app monitoring, a larger stated coverage area, a slim footprint, targeted De-NOx filtration, or actual air conditioning.
- Functions:Air purification, fan airflow, and heating
- Filter:HEPA 13
- Particle retention:0.3 microns
- Listed floor area:73 square feet
- Noise level:59.8 dB
- Oscillation:Up to 350°
- Controls:Remote
- Dimensions:9.84 x 9.84 x 30.2 inches
Our verdict“I’d choose the HP10 for remote-first, all-season operation in a smaller room, but not for app monitoring, broad coverage, or true AC cooling.”
How We Picked
I ranked these five products by how well they serve the intent behind Dyson air conditioner: buyers want cooling comfort, but also need a clear account of what the machine can and cannot do. All five offer fan airflow; none is described as a compressor-based air conditioner. That makes room cooling claims a matter of perceived comfort from moving air, not lowering the room’s overall temperature. I put that distinction at the center of the comparison rather than treating each purifier fan as an AC.
My next dividing line was heating versus cooling-only operation. The HP2 De-NOx, HP1, and HP10 can provide warm airflow as well as fan cooling, which gives them more seasonal flexibility but adds a function buyers who only need summer airflow may not want. The PC1 and PC2 De-NOx keep the focus on air purification and cooling airflow. I gave the highest ranking to the HP2 because its feature set is broadest, while assigning the PC1 a strong position for buyers who do not need a heater.
I also weighed filtration specificity and room coverage. The supplied descriptions identify HEPA H13 filtration on the newer models, and the PC1, PC2, HP1, and HP10 list particle capture down to 0.3 microns. The HP2 description emphasizes capturing 50% more NO₂ and continuously destroying formaldehyde; the PC2 De-NOx description also calls out gases and formaldehyde. Those claims make the De-NOx versions more relevant to buyers focused on those pollutants, while the regular models may be a better fit when general particle filtration and airflow are the goal. Room-area figures are provided for the HP2, PC1, HP1, and HP10, but not the PC2, so I avoid treating their coverage as interchangeable.
Finally, I compared control options, size, and stated noise where the supplied details allow a fair distinction. App and voice features may suit buyers who want monitoring, while a remote-only model can be easier for people who want fewer setup steps. Stated noise levels vary among the models that list them, though the measurements are not supplied for every product and should not be treated as a complete noise ranking. I did not infer unlisted performance or treat promotional claims as independent test results. The order reflects use case and feature fit—not a claim that every buyer needs the most elaborate model.

Factors to Consider When Choosing Dyson Air Conditioner
When I compare Dyson products described as air conditioners, I start by separating air movement from active cooling. The models in this roundup are purifier fans, and some also work as heaters. Their airflow can feel cooler on skin, but none is described as using a refrigeration cycle to lower the temperature of a room. Match the machine to what you actually want: air circulation, filtration, supplemental heat, or a separate conventional AC.
Do You Need a Fan or a Real Air Conditioner?
This is the decision that should come before model names and filtration claims. The PC1, PC2 De-NOx, HP1, HP2 De-NOx, and HP10 all provide fan airflow. That can help people feel cooler when air moves across them, but it does not remove heat from the room. If a hot room needs to reach a lower temperature, choose a properly sized air conditioner and treat a Dyson purifier fan as a separate comfort or air-quality appliance.
For personal airflow and purification, the PC1 or PC2 may fit better than a model with a heater you will not use. If you want warm airflow in cooler months as well, compare the HP models. My ranking does not label any of these as a substitute for an AC: the product descriptions support fan cooling, not active room cooling.
Choose Heating Only If You Will Use It
The HP2 De-NOx, HP1, and HP10 combine fan airflow with a heater. That all-season role can make one appliance more useful across the year, particularly if you want both purified airflow and supplemental warmth. The HP2 is the most feature-rich of the three, while the HP1 and HP10 have a stated 73-square-foot floor area. The HP10 is remote-first; the HP1 adds app control in its supplied specifications.
The PC1 and PC2 De-NOx omit heating and focus on airflow and purification. That is a cleaner match if you do not need heat or want a cooling-fan role without adding heater functionality. It is not automatically better to buy the most versatile model: unused functions add complexity without improving the cooling limits shared by the whole lineup.
Match Filtration to Your Main Air Concern
For general particle filtration, several descriptions specify capture of 99.97% of particles down to 0.3 microns, with HEPA or HEPA H13 filtration. The HP2 description instead highlights its sealed HEPA H13 filter system and calls out a 50% increase in NO₂ capture, along with odors, gases, and continuous formaldehyde destruction. The PC2 De-NOx description also names gases and formaldehyde removal, making it the cooling-only model with the clearest gas-focused role.
Do not treat the standard PC1 and the De-NOx models as identical simply because they share a fan-and-filter format. The PC1 description centers on allergens and pollutants, while the De-NOx products call out additional contaminant categories. If gas or formaldehyde filtration is a priority, compare the wording and supporting information for the specific pollutant you care about. These product claims do not tell me how a particular room’s air quality will change under every condition.
Use Listed Coverage as a Starting Point
The supplied floor-area figures are 109 square feet for HP2, 101 for PC1, and 73 for HP1 and HP10. No floor-area figure is provided for PC2. These are useful comparison points, but I would not assume a listed area guarantees identical performance in every room; layout, ceiling height, placement, airflow obstructions, and how the device is operated all affect what a person experiences.
If a stated room-size reference is important, the PC1 or HP2 is easier to compare than the PC2 because their listings include coverage. The HP1 and HP10 have smaller listed figures, which may suit a more contained space. For a room beyond the listed area, compare the product’s full manufacturer guidance before buying rather than extrapolating from the tower’s size or the amount of air it appears to move.
Decide How Much Smart Control You Want
The HP2, PC1, PC2, and HP1 describe app-related control or monitoring, with voice features mentioned for some models. Connected functions can be helpful if you want to check air quality or adjust a unit remotely, but they may involve Wi-Fi and app setup. Review the specific control details for the model you are considering; a remote may still be included even when the app provides additional capabilities.
The HP10 is the clearest remote-first option in this group and is not listed as app compatible. That is a limitation if remote monitoring from a phone matters, but it can be a benefit if you prefer a simpler control routine. Choose based on how you expect to operate the machine rather than treating app connectivity as a universal advantage.
Compare Size, Noise, and Daily Placement
The models differ in height and footprint. The PC1 and PC2 are listed at 41.34 inches tall, while the HP1 and HP10 are about 30 inches tall. HP2 stands at 36.34 inches and weighs 12.2 pounds. The HP10’s listed base dimensions are wider than the PC tower measurements, so a shorter design is not always the same as a smaller footprint. Check where the device will sit and whether the controls, oscillation, and airflow have room to work.
Noise figures are available for only some products: 59.8 dB for HP10, 61.4 dB for PC1, and 63 dB for HP1. Those listed values offer a reference but do not establish a complete ranking across all five models because figures are missing for HP2 and PC2 and no shared measurement conditions are provided. If the unit will run near a bed or desk, use the model’s stated sound information and available operating modes to judge fit rather than assuming every Dyson fan is quiet.
Make the Final Choice by Use Case
For the broadest combination of heating, fan airflow, app control, and gas-focused filtration, my leading choice is HP2 De-NOx. For a purifier fan without a heater, PC1 offers a listed 101-square-foot area and broad oscillation. PC2 De-NOx makes more sense when its gas and formaldehyde focus is the reason for buying, though its supplied listing lacks a coverage figure. Choose HP1 for app-enabled all-season use in a smaller listed area, or HP10 for remote-first operation with night mode.
Before ordering any of them as a supposed air conditioner, ask whether you need air movement or an actual reduction in room temperature. If the answer is the latter, buy a real AC for that task. A Dyson purifier fan can serve a different role alongside it, but should not be expected to do the same job.
Frequently Asked Questions
Is a Dyson purifier fan an air conditioner?
No. The five products compared here are purifier fans, and some also heat. Their airflow can create a cooling sensation by moving air over a person, but the supplied product details do not describe compressor-based cooling that lowers the room’s temperature. If you need to cool a room during hot weather, choose a conventional air conditioner sized for that space.
Which Dyson model in this roundup is best for cooling airflow?
I’d choose the PC1 if you want cooling airflow with air purification but do not need a heater. It lists up to 350° oscillation, ten fan levels, and coverage of 101 square feet. If gas and formaldehyde removal matter more than a published coverage figure, the PC2 De-NOx is the more specialized cooling-only alternative. Neither model actively chills a room.
Which model also provides heat?
The HP2 De-NOx, HP1, and HP10 combine air purification and fan airflow with heating. HP2 has the broadest supplied feature set and a listed 109-square-foot floor area; HP1 adds app control and lists 73 square feet; HP10 lists a remote, night mode, and 73 square feet. The PC1 and PC2 De-NOx are cooling-fan and purifier models without a heater.
What is the difference between the De-NOx models and the regular models?
The HP2 and PC2 De-NOx descriptions call out gas and formaldehyde-related filtration, while the HP2 specifically claims 50% more NO₂ capture. The standard PC1 and HP1 descriptions focus more on HEPA capture of microscopic pollutants and allergens. If those gas-related contaminants are your main concern, compare the De-NOx details; if you mainly want general particle filtration and airflow, the regular models may cover your needs without the same specialized emphasis.
Which model should I choose for a small room or simple controls?
HP1 and HP10 each list a 73-square-foot floor area, so either may suit a smaller room if you also want heating. I’d favor HP1 for app and remote control, or HP10 if you prefer a remote-first setup and night mode. For cooling airflow without heat, PC1 lists 101 square feet, while PC2 De-NOx has no supplied coverage figure. Check room placement and the manufacturer’s guidance before relying on a listed area alone.
Conclusion
My first choice for an all-season purifier with the broadest feature set is the HP2 De-NOx, especially if heating, app control, and its enhanced NO₂ and formaldehyde claims matter to you. For buyers focused on purified cooling airflow without a heater, I’d choose the PC1; choose PC2 De-NOx instead when the gas and formaldehyde emphasis is the main reason for purchase. The HP1 suits someone who wants app-enabled heating and purification in a smaller listed room, while HP10 is the better match for simple remote control and night mode.
My most important recommendation is about expectations: none of these is a true air conditioner. If you need your room’s temperature lowered, buy a conventional AC. Choose a Dyson purifier fan for moving and filtering air, and add the heater feature only if you will use it. That distinction is more important than selecting between a few differences in oscillation, controls, or design.
