Dyson manufactures some of the highest quality air purifiers on the market. If you need help deciding which one to pick, you are in the right place.
The Dyson Pure Hot + Cool air purifier comes in three models: the Dyson HP01, Dyson HP02, and the Dyson HP04.
The HP01 was the Pure Hot + Cool lineup’s first model. Dyson later released Dyson HP02 – the upgraded version of HP01 – then followed by the HP04, the latest model of the lineup.
The HP01 and the HP02 are almost identical except for the added Wi-Fi connectivity feature on the upgraded version while HP04 is more advanced and much more expensive.
In this article, we will be looking at the differences between the HP02 and the HP04 – skipping the HP01 since it has the exact same specs and design as the HP02 minus the Wi-Fi controls.

Differences between the Dyson HP02 and HP04
- The HP04 uses a larger HEPA filter and separate activated carbon filter. The HP02 uses a combination filter.
- The HP04 displays more information about the pollutants in your room. The HP02 only shows you the target temperature.
- The HP04 can swing around 350 degrees, the HP02 can only oscillate 180 degrees.
- The HP04 is more expensive than the HP02.
Similarities between the Dyson HP02 and HP04
- Both can blow hot or cool air while purifying the air in the room.
- Both are WiFi enabled and compatible with Alexa and your smartphone.
- Both have a night time mode
- Both come with a remote control.
Comparing Dyson HP02 vs HP04 in Detail
All Dyson Pure Hot + Cool fans have 3 in 1 functionality: air purifier, heater, and cooler.
The HP02 supports two types of filters.
The HEPA Filter captures 99.97% of microscopic particles 0.3 microns in size. Why 0.3? Because this is the size that evades most regular filters.
The Activated Carbon Filter reduces odors while removing VOCs (volatile organic compounds).
On the other hand, the HP04 has a more advanced filtration system.
The HP04 comes with an LED screen that allows you to check what particles and gases are currently lingering in the room. The HP02 also has an LED screen but it only shows the target heating temperature. The HP04 also has a 350-degrees of oscillation and can blow purified, hot, and cool air around the full radius of the room and it includes a Backward Mode – a mode where you can enjoy purified air without heating or cooling function. On the other hand, the HP02 does not support the 350-degree oscillation and the Backward Mode.
Another major difference is the price point. Since the HP04 device has a number of additional elements and benefits it costs a little higher than the HP02.
Dyson has a consistent design language for all of its air purifiers which distinguishes them from other brands. The HP02 and the HP04 are very similar in terms of design, although there are some minimal differences like the HP04 is slightly bigger and heavier than the HP02, it is safe to point out that the designs are the usual Dyson style.
It has a long-range projection and evenly circulates the already purified, cooled, and heated air across the room. The HP01 also pivots on its own and is remote control operated – letting you control the air purifier and change modes with ease.
When it comes to the modes, the two devices have the same modes – except for the Backward Airflow Mode – they both have the following modes: Jet Focus Control, Diffused, and Night modes. The Jet Focus Control mode has a more controlled and focused air stream, the Diffused mode has a wider airflow, and the Night mode dims the display and purifies the air quietly. Both models from the Dyson Pure Hot + Cool lineup also support WiFi connectivity, Dyson Link App, and voice control. They also have a space heater, sports a HEPA filtration system, and fan which will distribute the purified air in the room. The HP02 and the HP04 are both certified asthma and allergy friendly by the Asthma and Allergy Foundation of America.

Conclusion
The bottom line is that both the Dyson HP02 and the Dyson HP04 are great units and they are worth investing in because they do the job of keeping the air in your room clean. The Dyson Pure Hot + Cool air purifiers are for everyone, especially allergy sufferers, asthmatics, light smokers, and pet owners. Picking which model to get, whether the HP02 or the HP04, can be a tough decision. So here are the things that you might want to consider before buying:
- First, you have to consider your budget. If you are trying to save a few bucks then go with the HP02 rather than the HP04.
- If you want an air purifier with more advanced functionalities, choose the HP04. The HP04 has a better filtration system and it also shows the air quality data on the machine. Aside from that, the HP04 has a finer air blowing directions, distribution, and control. It costs a little more than the HP02 and you’re actually getting a more advanced device. But if a simple machine is okay with you then get the HP02.
- If you need a big oscillating angle, pick the HP04.
- The HP04 is a good choice if you want to know the level of pollutants lingering in your home. It has visual cues on the front display in addition to the Dyson Link App.
- If you want to have the option to turn off the heating and cooling functions get the HP04. It has a Backward Airflow Mode.
If given the choice, I would get the HP02 for myself since it’s cheaper and the specs are not far from the HP04. It gets the job done and honestly, aside from the new filters and the Backward mode, nothing else is new.
Thank you so much for such a great post.
Thanks a million. I wish Dyson explained this. Something which is even more confusing is in Australia we have the HP03 which seems to be nearly identical to the HP02.
Great comparison between the two units. I went to Dyson site and I could not find 02 and 04 just found HP06 and 07. This really helped me with my decision. Thank you.
