AI Verdict
This is a premium 3-in-1 device offering HEPA H13 purification, 76 gallons/second fan airflow, and whole-room heating, designed for users prioritizing air quality and convenience in smaller spaces.
This Dyson unit is a strong contender if you need a compact, multi-function device for air purification, supplemental heating, and fan-based cooling in a smaller room. Its 3-stage HEPA H13 filtration and NO₂ capture are top-tier, but the fan-only 'cooling' and remote-only heat control can be limiting for some users.
If true cooling is a priority, look for a unit with a compressor-based air conditioning function, not just a fan.

Pros
- Fully sealed, 3-stage HEPA H13 grade filtration captures 99.97% of particles as small as 0.3 microns, and continuously destroys formaldehyde.
- Advanced K-Carbon filter captures 50% more NO₂.
- Dyson Air Multiplier technology projects 76 gallons per second of powerful airflow for heating and fan-based cooling.
- App Connectivity allows monitoring of air quality, scheduling, and remote control for fan and purification settings.

- Operates quietly at lower fan speeds.
Cons
- The 'cooling' function is solely a fan and does not provide actual air conditioning, which may not be sufficient in very warm conditions.
- Heating and fan power can be weak, with some users reporting air feeling cold only 3 feet away at max heat.
- Heat settings cannot be controlled via the MyDyson app, requiring the physical remote for activation and adjustment due to UL regulations.
- Some users report the plug and cable getting extremely hot during operation, posing a potential safety concern.
- Purification effectiveness, particularly CADR, is questioned by some users as being comparable to much cheaper purifiers.
Dimension Scores
The 3-stage HEPA H13 filtration and NO₂ capture are strong, but heating and fan cooling power are often described as weak for larger spaces, and the 'cooling' is not true AC.
App connectivity for monitoring and scheduling is convenient, but the inability to control heating via the app is a significant limitation.
The unit has a sleek design and is recognized for its aesthetics, but reports of the power plug getting extremely hot raise concerns about long-term safety and component quality.
While it heats a room evenly, the effectiveness of its heating and cooling (as a fan) can be limited, potentially leading to longer run times to achieve desired comfort levels, impacting efficiency.
Best For
- Individuals with allergies or sensitivities to airborne particles, gases, and formaldehyde.
- Small to medium-sized rooms where a multi-functional device can reduce clutter.
- Users who want real-time air quality monitoring and app-based scheduling for purification and fan functions.
- Those needing supplemental heating in winter and fan-based airflow in summer.
Not Recommended For
- Anyone expecting true air conditioning for cooling a room.
- Large, open-plan living spaces where its heating and fan power may be insufficient.
- Budget-conscious buyers, as its premium price point is a significant drawback for many.
Watch Out For
- The 'cooling' feature is just a fan, not an air conditioner, so it won't drop the room temperature, only circulate air.
- You can't turn on or adjust the heat from the MyDyson app; you'll always need the physical remote for heating control.
- Some users have reported the power plug and cable becoming extremely hot, which could be a safety issue.
- Despite its advanced filtration, some users on Reddit claim its Clean Air Delivery Rate (CADR) is similar to much cheaper purifiers, suggesting less effective air cleaning than expected for the price.
- The heating and fan capabilities might feel weak, with one user noting the air felt cold just 3 feet away on max heat.

What Buyers Say
The biggest head-scratcher with this Dyson is that for a premium price, its 'cooling' is just a fan, not actual air conditioning, which really disappoints users expecting more. While the air purification, especially the NO₂ and formaldehyde destruction, gets praise, some folks on Reddit question if its cleaning power is truly better than much cheaper purifiers. The app is handy for monitoring and scheduling, but the fact you can't even turn on the heat with it feels like a missed opportunity. Plus, a few people have had issues with the power cable getting dangerously hot.
“Honestly, I bought this thinking I'd finally get something that cools my room in summer, but it's just a fancy fan! For $600+, I expected actual AC, not just air blowing around. The air quality stuff is cool, but the 'hot' and 'cool' part is a total letdown. My old space heater works better.”
Common Praise
- The 3-stage HEPA H13 filtration system makes a noticeable difference in air freshness and quality.
- The MyDyson app is intuitive for monitoring air quality, setting schedules, and controlling fan functions.
- Its multi-function design (purifier, heater, fan) helps reduce clutter in a room.
- The unit operates quietly at lower fan speeds, making it less disruptive.
- The sleek design is aesthetically pleasing and blends into home decor.
Common Complaints
- The 'cooling' feature is just a fan, not an air conditioner, and doesn't actually lower room temperature.
- Heating and fan power are often described as weak, especially for larger rooms, with limited effective range.
- The heating function can only be activated and adjusted with the physical remote, not through the app.
- Some users reported the power plug and cable becoming extremely hot, raising safety concerns.
- The high price doesn't always justify the performance, particularly when compared to dedicated, cheaper alternatives for each function.
Ownership Tips
- You'll quickly realize that the remote is essential for heating, so don't lose it or let the batteries die.
- The 'cooling' is more like a strong breeze, so don't expect to replace your AC unit with this in a heatwave.
- Keep an eye on the power plug and cable for unusual heat, as some users have reported this as a safety issue.
- While the app is great for air quality data, you'll still be getting up to grab the remote for temperature adjustments.
- Filter changes are straightforward, but remember to factor in the cost of replacement filters, which aren't cheap.
Frequently Asked Questions
Does the Dyson Purifier Hot+Cool HP2 De-NOx actually cool a room like an air conditioner?
No, the 'Cool' function is a fan that circulates air, providing a cooling breeze, but it does not lower the room's ambient temperature like an air conditioner.
Can I control the heating function with the MyDyson app?
You can turn the heat off via the app, but due to UL regulations, you cannot turn on or adjust the heat settings using the app; this requires the physical remote control.
How effective is the air purification?
It features a fully sealed, 3-stage HEPA H13 grade filtration system that captures 99.97% of particles as small as 0.3 microns, removes odors and gases, and continuously destroys formaldehyde.
Is this unit quiet?
Many users report that the unit operates quietly, especially at lower fan speeds.
What is the De-NOx feature for?
The De-NOx feature, using an advanced K-Carbon filter, is designed to capture 50% more nitrogen dioxide (NO₂), which is beneficial for homes with gas appliances or those in urban environments.
Buying Guide
When looking at a multi-function device like this, you need to be clear about what each function actually does. 'Cooling' often means just a fan, not an air conditioner that actively lowers the room temperature. For purification, look beyond just 'HEPA' to the grade (like H13) and what other pollutants it targets, like NO₂ or formaldehyde. And for heating, consider the room size it's rated for and user reports on its actual warming power.
HEPA H13 grade filtration
This means the filter is certified to capture 99.97% of particles as tiny as 0.3 microns, which includes most allergens, dust, and pet dander. Think of it like a super fine sieve for your air, catching almost everything you don't want to breathe.
NO₂ capture
Nitrogen dioxide (NO₂) is a gas often produced by gas stoves, cars, and power plants. Capturing it means the purifier can help reduce indoor air pollution from these sources, which is a big deal if you cook a lot or live in an urban area.
Air Multiplier technology (76 gallons/second)
This is Dyson's way of saying it moves a lot of air smoothly and powerfully. For you, it means a consistent, strong airflow for heating or fan-based cooling, without choppy gusts.
App Connectivity
This lets you see your home's air quality data in real-time, set schedules for when the unit runs, and control some functions from your phone. It's like having a dashboard for your air, giving you more control and insight.
Alternatives
If you need actual room cooling, search for 'portable air conditioner' or 'window AC unit.' If purification is your main goal and you're on a budget, look for 'HEPA air purifier with high CADR' to compare clean air delivery rates.
