Dyson DP 04 is Best For:

  • People with pet dander, hair, and fur allergies – this device combines a True HEPA and Activated Charcoal filter to capture most pet allergens. 
  • People living with asthma – the DP 04 can remove most of the air contaminants that trigger asthma, including pollen, mold spores, dust, and dust mites. 
  • Homeowners with medium-to-large room spaces – the air multiplier function of this device make it ideal for 290-600 sq. ft. room spaces. 
  • Smart Homeowners – Besides its sleek and futuristic look, the DP 04 has Wi-Fi, Alexa, and Siri compatibility. 

Construction Design and Materials Review 

The Dyson DP04 features a sleek and modern design combining a fan and an air purifier in one unit. The signature hollow loop is perhaps what attracts more attention on this air purifier.

This model has a metallic body that makes it notably stronger and firmer. This is an incredible change from the plastic air purifiers that fill the market. 

The DP04 uses the popular bottom-to-top air-in, air-out system. The air filters are configured to suck air from all angles through the perforated shell. 

Also, other than its white finish, you can get this model in iron and blue finish, or black and nickel finish.

Size, Weight, and Placement Review

This is essentially one of the most compact air purifiers from Dyson. It measures 8.8’’ by 13.8’’ by 27.2”, and weighs 10.2 pounds. 

In our opinion, this is an incredible size-weight combination for an air purifier that is meant to stay on desktops.

We often recommend placing an air purifier at the center of the room, especially when the air vents are fixed. However, we believe placement won’t be an issue with the Dyson DP04 Pure Cool thanks to its 360-degree air intake design and air multiplier function. Its 350-degree oscillating base also offers a wide angle of clean airflow, and this makes placement even much more straightforward. 

We Reviewed How the Dyson DP04 Works:

This air purifier utilizes a 2-stage mechanical air purification design to remove air contaminants. Dyson opts to fit this model with its best choice of True HEPA and Activated Charcoal filters instead of ionization and UV light technologies. 

  • True HEPA filter– HEPA stands for High-Efficiency Particulate Air. A True HEPA refers to a filter that has been tested and certified to remove 99.97% of 0.3-micron air pollutants. This filter is suitable for trapping bacteria, viruses, dust, dust mites, pet dander, hair, fur, mold spores, and pollen. 
  • Activated Charcoal– this filter removes common household odors and smells. It also captures Volatile Organic Compounds (VOCs), including formaldehyde, nitrogen dioxide, and benzene.

Controls and Operation Modes Review 

dyson dp04 remote

There are 3 ways of controlling this model; using a remote control, the Dyson Link App, or through Alexa and Siri.

The remote has a magnetic feature that attaches it to the top of the purifier to reduce the possibility of misplacing it.

The standout feature of this air purifier’s control panel is its sensor kit. Unlike regular air purifiers that have a single sensor to detect general air quality changes, the DP04 uses 3 distinct sensors for humidity, temperature, and gases.

Auto and sleep modes come standard in most modern air purifiers, and the DP04 has them too. The diffused mode, however, is a unique aspect of Dyson air purifiers. This mode ejects cleaned air through the back, so it does not hit you directly. Technically, the diffused mode makes the DP04 an all year round device.

Performance Review


Dyson is not exact on this air purifier’s coverage. However, they say that it has been tested in a 290-sq. Ft. room. In our opinion, this air purifier’s maximum airflow of 77 gallons per second makes it ideal for medium-to-large spaces of up to 600 sq. ft.

Noise Output

At the highest fan speed, this air purifier records a noise output of 57 dB. This is almost as loud as the sound of heavy rainfall. It’s barely audible in its lowest speed level settings, though, in case you prefer silent nights.

Power consumption

The DP04 is among the most energy-efficient air purifiers on the market today. With a power rating of 4-32 watts, this model would cost you the utmost $12 annually if you run it for 8 hours non-stop for a whole year.

Well, most air purifiers generally don’t consume a lot of electricity. However, this model’s performance is quite commendable, especially considering that it doubles as a fan too.


This air purifier has very minimal maintenance needs. Besides wiping it down whenever necessary, the other major requirement is to replace its air filters as needed. Dyson recommends replacing the filtration kit annually using the Dyson Replacement Sealed 2-stage 360-degree filter system.  

Warranty – Dyson offers a 2-year warranty only for the DP04. You’ll also get a generous 30-day money-back guarantee to decide whether or not to keep the device.
