Dyson HP01 vs HP04 – What Has Been Upgraded In the Newer Model?

Dyson offers a wide selection of premium home appliances in the market and their Pure Hot + Cool series of fan purifiers is one of the best.

The Pure Hot + Cool series has three models: the HP01, HP02, and the HP04. The series first released the HP01 as their flagship model and because of its success, Dyson upgraded it to HP02 and then later on upgraded it to HP04. The series is known to have three main functions: heat, cool, and purify.

The HP01 is an impressive machine and comes at a cheaper price, however, the HP04 has new features to offer – features that the HP01 doesn’t have. Read on if you want to know more about these features and the differences between these two Dyson purifier fans.


Differences between the Dyson HP01 and the HP04

  • The HP01 uses a combination filter of 360 Glass HEPA and Activated Carbon while the HP04 uses a larger HEPA filter and a separate Activated Carbon filter which makes it better at capturing air pollutants.
  • The HP01 is not WiFi-enabled while the HP04 can be connected to WiFi and can be linked to Alexa. It can also be controlled via the Dyson Link App.
  • The HP04 displays more information about the pollutants lingering in the air while the HP01 only displays the simple and intuitive controls.
  • The HP04 can swing around 350 degrees, the HP01 can only oscillate 70 degrees.
  • The HP04 is more expensive than the HP01.

Comparing the Dyson HP01 vs HP04 in Detail

Dyson has a reputation of providing quality products and they did not disappoint us with the introduction of their Pure Hot + Cool lineup.

Since the HP01 was the first to be released in the series, it is bound to be upgraded in the future and unlike other brands who phase out their products once it’s upgraded, Dyson continued manufacturing the HP01.

First stop is the design. The two machines almost have the same look except for some slight changes. The HP04 is bigger and weighs heavier than its predecessor but other than that, they both look like the classic Dyson design – bladeless, sleek, modern-looking, and aesthetically pleasing.

The HP01 is a 3-in-1 machine that serves as a heater, a fan, and a purifier. Its biggest feature is its purifier with HEPA (High-Efficiency Particulate Air) filter which removes 99.97% of air contaminants 0.3 microns in size. The Activated Carbon reduces odors while also removing the VOCs (Volatile Organic Compounds).

On the other hand, the HP04 uses the same filter but better – It has a separate filtration system and a more improved HEPA + Carbon filter. However, the new filters are not the highlight of the HP04. The huge difference between the two is the WiFi connectivity of the newest model in the lineup.

The HP04 is equipped with WiFi and can be connected to Alexa and Dyson Link App, meanwhile, the HP01 doesn’t have that. The Dyson Link App is more than just an app. It allows you to schedule your air purification, heating, and cooling and it also reports the quality of air in your room. Aside from that, the app will also allow you to control the HP04 even when you’re not home.

The HP04 is also voice control enabled which will let you command the device through a smart home technology like Alexa.

Another thing to keep in mind is the display. The HP04 allows you to check what kind of pollutants are present in the room while the HP01 only shows the temperature and the basic modes of the device.

When it comes to the modes and other features, the HP04 has more to offer than the HP01.

The HP01 and the HP04 both have the Jet Focused Control and Diffused Mode. They also have Night Mode where the displays of the devices dim and the air purifier runs quietly but the HP04 has a Backward Mode which allows you to use the purifier without turning on the heater or the fan. The HP01 doesn’t have that feature and it always blows purified air while the fan is turned on.

While the room size coverage of the two is the same – they cover 400 square feet for air purification, heating, and cooling – the oscillation range of the HP01 and the HP04 are also significantly different. The HP04 can circulate air in the entire room because of its 350-degrees of oscillation while the HP01 enjoys 70-degrees of oscillation.

When it comes to the price, the HP04 is a lot more expensive than the HP01 because of its upgrades but it’s understandable since you get what you pay for.

The Dyson Pure Hot + Cool’s HP01 and HP04 are great fan purifiers because they deliver results and you get your money’s worth. The fans from the Pure Hot + Cool lineup all have three functions: purifier, heater, and fan. The HP01 and the HP04 have a lot of differences because of the upgrades made to the HP04 overtime. The units are both safe for babies and pets because their blades are hidden. They are also allergy and asthma friendly. The big difference lies in the WiFi connectivity feature of the HP04 but other than that, they are identical in terms of build and functions. If you are torn which to pick here are the things that you might want to look at:

  1. If you are looking for a simple purifier fan that does the job, you can get the HP01.
  2. If you want to save money, opt for the HP01. It’s decent enough to purify the air, provide heat, and cools you too on hot days.
  3. If you are after the WiFi connectivity, the benefits of the Dyson Link App and smart home compatibility, choose the HP04.
  4. If you want to learn more about the air pollutants in your room, HP04 is the best pick.


The HP01 is okay. It’s a great machine but, if I were to choose what unit to get between the two Dyson Pure Hot + Cool series, I will choose the HP04. Yes it’s a little pricey but the benefits that you’ll be getting are worth it. The filters are upgraded and you can connect it to the Dyson Link App and Alexa plus with the technology that we have these days, WiFi is really important, although not all appliances need to have WiFi connectivity. I enjoy the ability to control my devices while away, but it is not a deal breaker if it doesn’t have WiFi.
