Dyson Pure Cool DP04: A Symphony of Air Purification

Written By: Dr Fahad Yasin

In the quest for a high-quality fan and air purifier combo, the spotlight falls upon Dyson’s selection, and among them, the Dyson Pure Cool DP04 takes center stage.

A compact version of its predecessor, the TP04, this device showcases an intelligent blend of cooling fan and air purifier capabilities, all driven by cutting-edge technology that intelligently detects indoor air quality and adjusts its purification settings accordingly.

If you’re looking for a Dyson fan and purifier and don’t need a “heating mode” (like the Dyson HP04 model), then the DP04 could be an excellent option for you.
COMPACT, HIGH-PERFORMING AIR PURIFIER

The Dyson Pure Cool DP04 is a more compact air purifier, but still designed for cleaning medium to large sized rooms. You can set it on Auto mode for autonomous adjustments to real-time air quality conditions, or customize settings to your liking. For an all-around solid fan and purifier, it’s hard to beat the DP04.

Pros

Cons

Dyson Pure Cool Design

 The DP04 dons a design akin to the HP04 model, featuring a compact body that doesn’t compromise on its ability to move a substantial volume of air.

 

Uniquely, it replaces the oval amplifier of the TP04 and HP04 models with a round amplifier, resulting in a surprising increase in airflow, making it stand out in the crowd.

For comparison, here are the stats on airflow vs. size, by model:

Dyson TP04
Tower design
Oval amp
361 liters / sec
Dyson HP04

Oval amp
310 liters / sec
Dyson DP04
Compact design

Round amp

419 liters / sec
NOTE – The Dyson HP04 functions as a heater and as a cooling fan, depending on which mode it is set on.

The DP04 has a white body with silver accents around the air intake area as well as accents on the amplifier.

It is also available in a black and nickel finish or an iron and blue finish.

The Controls

The controls on the Dyson Pure Cool DP04 are similar to what you’ll find with other 4th generation Dyson Pure Cool models.

 A round digital display screen serves as the hub for various settings, providing vital information on:

  • Air quality
  • PM 2.5
  • PM 10
  • VOCs
  • NO2
  • Temperature
  • Humidity
  • Filter Lifespan

The Dyson Pure Cool DP04 can be controlled with:

  • Remote Control
  • Voice Control (via Amazon Alexa)
  • Smartphone-based App Control (via Dyson Home app)
To help keep track of the remote control, it magnetically attaches to the top of the purifier.

1) Remote Control

The physical remote control is a nice feature included on the Dyson DP04 air purifier.

Using the remote control, you can:

  • Power on / off
  • Check filter status
  • Adjust fan speed
  • Reverse air flow
  • Oscillate
  • Auto mode
  • Night mode

2) Smart Control

From the app, you can see additional details about the indoor air quality of your home as well as outdoor air quality.

Smartphone-based app control via the Dyson Home app.



You can turn the purifier on / off, change modes, change fan speed, angle of oscillation, and many other features for a custom air experience.

Or you can simply set the purifier on “Auto” and let it analyze the air quality and adjust as needed.

The Filters

The Dyson DP04 features duo filters.

The two filters used by the Dyson Pure Cool DP04 includes:

  • A strong focus on air purification is evident in the inclusion of a HEPA filter, designed to capture particles as minute as 0.3 microns.

  • An activated carbon filter to neutralize pesky odors.

The Modes

 The DP04 caters to various preferences with its three primary modes:

  •     Auto Mode: Intelligently assesses indoor air quality and adjusts fan speed and settings accordingly for optimal air purification.
  •     Custom Mode: Provides the freedom to manually customize fan speed, airflow direction, and oscillation, allowing users to fine-tune their air experience.
  •     Night Mode: A thoughtful addition that ensures a peaceful night’s sleep, operating with minimal noise and dimmed displays.

Air Quality Assessment

 A hallmark of the DP04’s intelligence is its real-time air quality assessment, displayed on the digital screen and accessible through the Dyson app.

 

 Color-coded indicators (red, yellow, and green) provide an easy-to-understand visual representation of air quality, empowering users to stay informed.

On the digital screen, the air quality is shown as a line chart where red indicates poor air quality, yellow indicates medium air quality, and green notes good air quality.
You can also scroll through other more specific air quality menus using the remote control.
The DP04 can also tell you the type of pollutants that it senses when air quality is poor.
On the app, there are a few more features that are available, showing indoor and outdoor air quality. The app includes details on:

  • Temperature
  • Humidity
  • Current AQI (air quality index)
  • Particulate matter (PM2.5 and PM10)
  • VOCs
  • NO2
  • Air quality history (over time)

The Dyson Pure Cool DP04 is designed as a desk air purifier, but seems hefty enough to be placed directly on the floor.

 A noteworthy 94% improvement in PM 2.5 air quality demonstrates the purifier’s capability to deliver exceptional results.

During the testing process, we’re looking at a number of stats, but a lot of it comes down to the overall particulate count and it’s relationship to AQI (air quality index).

Setup & Usability

 Simplicity reigns in the setup process, allowing users to get up and running in no time.

To get started, you need to:
