Combining the functions of an air purifier, heater, and cooling fan, this multi-functional wonder promises to revolutionize indoor air quality.
GREAT PURIFIER FOR HEATING & COOLING
The Dyson HP04 heats, cools, and purifiers the air. The HP04 version is equipped with both a HEPA filter and carbon filter (for odors / VOCs). It offers real-time air quality assessment or features can be customized for variable needs. A solid multi-function air purifying unit.
Pros

- Automatically detects indoor air quality and adjusts appropriately
- Can be controlled with a smartphone via the app, remote control, or voice control (via Amazon Alexa or Google Assistant)
Cons
- Very pricey
Dyson Pure Hot & Cool Design
True to Dyson’s commitment to sleek design, the Pure Hot + Cool HP04 features a compact body in pristine white with stylish silver accents.
Its two main parts comprise:
- The base: housing the filters, air input, and control panel.
- The amplifier: an open vessel for distributing purified air using Dyson’s bladeless technology.
If you’re concerned about max airflow, the Dyson Pure Hot & Cool HP04 has a max airflow of 310 liters / second.
The Controls
- Intelligent Sensor-based System: The HP04’s on-board sensors constantly monitor air quality and automatically adjust settings, offering a hands-free, intuitive purification experience.
- Smartphone App: Through the Dyson Home app, users can control and monitor the HP04 from their smartphones, accessing features like timer settings, fan speed adjustment, and air quality reports.
- Voice Control: For added convenience, the HP04 is compatible with voice-controlled assistants like Amazon Alexa or Google Assistant, allowing for effortless hands-free operation.
The Filters
Armed with both a HEPA filter and a carbon filter, this air purifier tackles particles as minuscule as 0.3 microns and effectively neutralizes odors and VOCs (volatile organic compounds).
The Modes
- Auto Mode: In Auto Mode, the HP04 intelligently adapts to the surrounding air quality, adjusting fan speed and heat settings as needed to maintain optimal conditions.
- Custom Mode: Users have the freedom to manually adjust fan speed, heat settings, and airflow direction through the remote control or app, tailoring the air purification to their specific preferences.
- Night Mode: Perfect for undisturbed sleep, Night Mode operates at a lower decibel level, dims all lights and screens, and maintains a peaceful indoor environment.
Air Quality Assessment
There is a small house which displays stats about the inside of your home, including:
- Label (like Kitchen, Living, Upstairs, Downstairs, etc)
- Temperature (indoor)
- Humidity (indoor)
- Particulate data
- PM10
- VOC
- NO2
There are also stats listed for outside the home, which includes:
- Label (generally city name)
- Current weather icon
- Air quality index number (AQI)
- Temperature (outside)
- Humidity level (outside)
- Particulate data
Air Quality Color Indicators
When the line is green, that means that the indoor air quality is at a healthy level.
As the line raises to yellow, that means that there are a few particulates that need to be addressed in order for the air to be at its best quality.
And when the line in red, that means that there are serious contaminants that the purifier needs to tends to. This could be caused by something simple, like an nearby door being left open for too long or cooking.
Size & Dimensions
The Dyson Pure Hot and Cool is a compact yet powerful air purifier designed to purify even large rooms.

Performance
In a comprehensive in-home assessment, the HP04 underwent rigorous testing to evaluate its air purification capabilities.
Starting with an initial air quality measurement, the purifier operated for one hour in a closed room to treat the air.
After the purification cycle, air quality was reevaluated, and the results were staggering. The HP04 removed a remarkable 98% of air particulates from the medium-sized test room, demonstrating its efficacy in treating indoor air pollutants.
The device’s performance closely resembles that of the Dyson TP04 air purifier, boasting exceptional purification results and the ability to enhance PM 2.5 air quality by a significant 97%.
The Test
While we haven’t yet tested the air purification performance of the Dyson HP04, it has virtually the same purification specs to the Dyson TP04 air purifier (which we tested here) so we can assume purification performance will be similar.
Starting Baseline
PM2.5: 7.4
PM10: 12.1
Particles: 599
AQI: 30
After 1 hour
PM2.5: 0.2
PM10: 0.2
Particles: 14
AQI: 0
Note: One area where they may be some difference is in the rate of air treatment. Specifically, the TP04 can tackle up to 361 liters/sec, while the HP04 model can only tackle up to 310 liters/sec. This means the TP04 can handle larger rooms, but the purification level should still be the same
- Air quality index
- PM 2.5
- PM 10
- Particulate count
Setup & Usability
- Unbox the purifier and remove all packaging.
- Install the filters.
- Plug in the purifier.
- Turn it on.
The HP04’s setup and usability are effortless, with intuitive on-board sensors that automatically detect indoor air quality, allowing the device to default to auto mode upon activation.
Pure Hot & Cool Maintenance
- The device’s intelligent self-assessing design alerts users when it’s time to replace the filters, while the app offers additional insights into filter status and remaining life.
- Regular maintenance involves wiping down the exterior and occasionally replacing the filters to keep the HP04 running at peak performance.
You can also check the status of the filter life by checking on the app at any time.

A Competitive Market
In a market teeming with air purifiers, the Dyson Pure Hot + Cool HP04 stands out as a unique offering, combining multiple functions and cutting-edge technology. Competing brands have attempted to deliver similar features, but few have managed to match Dyson’s level of performance and design prowess.
Now don’t get me wrong, the Dyson HP04 is certainly not inexpensive. That said, as is the case with most Dyson products, I do believe that you get what you pay for.
Indeed, the HP04 is likely to perform as well as the TP04 in terms of indoor air quality treatment.
