A Comprehensive Breakdown: Dyson Pure Hot + Cool HP01 Review

Written By: Dr Fahad Yasin

Compact air purifier, heater, and fan Can purify, heat, and cool around 400 square feet of space Lower cost than many other Dyson models.
At a lower price point than many other Dyson models, does it still stand up to the Dyson name and technology? Let’s take a look at its features and abilities to find out.

The Dyson HP01 purifies the air while also heating or cooling, making it a great option no matter the season. The 360° glass HEPA filter removes bacteria, allergens, and other pollutants from the air. While the air flow rate is lower at 200 liters / sec, that still equates to around 400 square feet of coverage. Considering the price point and relative performance, it’s a great value option from Dyson.


  • Less costly than other triple function models
  • Small enough to move from room to room as needed
  • Remote control makes changing the mode and fan speed easy


  • Not wifi enabled
  • Not compatible with app controls

Dyson Pure Hot Cool Design

  • Oblong shape, housed on a round base
  • Control panel and digital display on the base
  • Comes in 4 color options: white and silver, Iron and silver, Scandium, Iron and blue

The amplifier is where the magic happens. The Air Amplifier technology pushes clean air continuously. The bladeless Dyson technology makes the fan safer to operate around small children and pets.

The max airflow of this particular Dyson model is not as high as other models, with a max airflow of 200 liters / second.
  • Max airflow of 200 liters/second, ideal for around 400 square feet
  • Other Dyson models have higher max airflow (HP04, TP04, DP04)
  • Lacks some features compared to other models, like smart home integration and a carbon filter

The Controls

The Dyson HP01 has a button on the front of the base that controls the:

  • Power On / Off
  • Adjust fan speed
  • Set the sleep timer
  • Change the mode (purifier, hot, cold)
  • Oscillation
This model also comes with a remote control to use for all the same features. It makes it easier to make changes from across the room.

The remote control is curved and magnetized, while the amplifier has built in magnetization so the remote can attach directly to the machine.

The Dyson HP01 has 10 different fan speeds as well. This makes it easy to find the optimal speed paired with temperature for just the right ambience in the room.

The Filter

  •  360 degree replaceable glass HEPA filter, removes up to 99.97% of contaminants.
  •  Uses a second-generation glass filter containing borosilicate microfiber and graphite.
  •  Tris-coated graphite eliminates odors, fumes, and gases.

Internal sensors ensure  pollutants, gases, and odors, are trapped inside the filter. 

The Modes

Jet Focused Technology for personalized heating and cooling, Modes include:

  • Focused Mode: for long range airflow.
  • Diffused Mode: for wider dispersion.
  • Sleep Mode: for automatic shut off at set times

Accessories & Parts

The Dyson HP01 air purifier comes with everything needed to heat, cool, and purify the air in any room.

The box contains:

  • Dyson Pure Hot + Cool HP01 air purifier
  • 360° Glass HEPA filter
  • Power cord
  • Remote control


Based on testing, all Dyson air purifiers perform at a similar level. Consistent design, parts, and filters across all models.

Here’s the process we use:

  1. Measure the indoor air quality prior to testing and document.
  2. Turn on the air purifier in an enclosed room and let it run for 1 hour.
  3. After the hour is up, measure the air quality again and document for comparison.
There are two indexes that we use to make the final determination, shown in the chart below.

    • PM2.5 = Particulate matter 2.5 micrometers and smaller
    • PM10 = Particulates matter 10 micrometers and smaller
    • AQI = air quality index, a standard government index based on different air quality factors

The air quality index (a number of different independent factors go into these numbers) and the particulate matter index (how many pollutants are in the air).

Is the Dyson HP01 a good value?

After considering the features and performance quality, is the Dyson HP01 a good value? Based on our tests, I’d say that it definitely is.

It may not have as many features as some of the other models Dyson offers (like the HP04), but it’s a multi-function air purifier, heater, and fan at a more reasonable price.

The Dyson Pure Hot + Cool HP01 is recommended for those seeking:

   – Multi-functionality with ability to purify, heat, and cool 

   – Versatility in terms of placement and portability

   – An intelligent thermostat for automatic temperature control

Should you buy the Dyson Pure Hot + Cool HP01?

Overall, the Dyson Pure Hot + Cool HP01 is a versatile and powerful device that efficiently delivers on its promise of multi-functionality. The device’s triple-feature capability (purifier, heater, and fan) makes it a versatile solution suitable for year-round usage.

It’s easy to use, comes with a handy remote control, and features HEPA filtration which makes it ideal for individuals with allergies or respiratory conditions.

Moreover, with its ability to oscillate, tilt, and direct airflow, it offers flexible options to target specific areas in the room. However, some might find the absence of WiFi connectivity a downside for the device, especially when smart home integration is increasingly common.

Nevertheless, for its premium design, top-notch performance, and the Dyson brand’s reliable reputation, the Dyson Pure Hot + Cool HP01 stands as a compelling investment for anyone seeking a high-performing multi-purpose air device.
