In-depth Review of Dyson DP04 Air Purifier:
Dyson is a trusted brand that designs and manufactures vacuum cleaners, hairdryers, heaters, bladeless fans, and air purifiers. Founded in 1991 by Sir James Dyson, the company began by making vacuum cleaners.
By the turn of the new millennium, Dyson expanded its product portfolio and began making other appliances. They include a bladeless fan and bladeless fan heaters.
This also led to the introduction of air purifiers to help remove air pollutants.
One of the best air purifiers to come off the Dyson assembly line is the Dyson DP04 air purifier. Here is why.
Performance
The Dyson DP04 air purifier is one of the most popular purifying fans that removes ultrafine particles from the air. What we liked about this purifier is that it comes with multiple air quality sensors. These sensors work by automatically detecting and alerting you of the presence of pollutants in the air.
That includes ultrafine particles (PM 2.5), VOCs, Nitrogen dioxide, larger allergens (PM 10), temperature, and humidity. When the purifier detects pollutants in the air, it alerts you via your Dyson Link app. Besides intelligent reporting, the Link app allows you to control and customize your purifier settings.
The app is compatible with iOS and Android smartphones. To ensure it works, follow the instructions to pair with your air purifier.
Besides the Wi-Fi capability, this air purifier features Air Multiplier technology. What’s impressive about this technology is that it delivers 77 gallons of air per second or 617 cubic feet of air per minute.
State-of-the-art Design
At 10.2 pounds, the Dyson Pure Cool DP04 design is not only sleek but compact too. The purifier’s total height is 27.2 inches, with the base diameter plus the plate at 8.8 inches.
Speaking of the base, it houses the filtration system and the LCD. It also houses the intake vent for the air purifier. The bottom of the air purifier has a 360-degree intake with perforated holes.
The design allows the purifier to suck in more dirty air from all sides for purification. Once the unfiltered air gets purified, its redistributed via the loop amplifier. The futuristic-looking amplifier has a diameter of 13.9 inches, and it’s impressive.
You can adjust the up and downward tilt of the air purifier manually. Also, you can set the oscillation angle between 45-degrees to 350-degrees. This will help to project the purified air all around your living space.
So, if you want the air purifier to release purified air in your home and cool you at the same time, set it to the forward airflow mode. But if you don’t want the blow from the air purifier, set it to the backward airflow mode.
However, Dyson DP04 can’t lower the room temperature. You will feel a little cold as the wind blows on your skin when set to forward airflow mode.

Dyson DP04 comes in white-silver and will blend easily with any modern interior. When it comes to materials, the air purifier has a solid build thanks to its metallic body.
As such, it’s stronger and durable. The good news is the compact design makes it suitable to use in any location in your home. You can use it in your living room, bedroom, or kitchen.
Two-stage High-grade Filtration
Dyson DP04 comes with a 2-stage filtration system that includes a sealed HEPA filter and an activated carbon filter. The HEPA filter is not only fully sealed but available as a 360-degree version. This filter captures and removes 99.97% of microscopic pollutants and allergens as small as 0.3 microns.
They include fine dust, pet dander, pollen, smoke particles, and others. What you need to know is that this is a glass HEPA filter. It is made with 29 feet of borosilicate microfibers, pleated over 238 times.
The granular activated carbon filter is in the 2nd stage of purification. The filter neutralizes odors by adsorption.
It also helps to remove VOCs, nitrogen dioxide, and formaldehyde. What we liked about the activated carbon filter is that it’s made of high-quality activated carbon granular. This is unlike other models that come with paper carbon.
As such, you should experience a significant difference in indoor air quality when you run the Dyson Pure Cool DP04 air purifier all the time.
After the air passes the activated carbon filter, it’s released via the bladeless air multiplier loop.
The air purifier is AAFA certified (Asthma and Allergy Foundation of America) for allergy and asthma friendly. Not only that. The purifier is completely ozone-free because it has no electronic filtrations.
As such, the California Air Resources Board certified the purifier as safe for use in homes and offices.
Room Coverage and CADR
Thanks to the air multiplier technology available in the air purifier, you can enjoy a healthier home as you work on your projects. What we noted is that Dyson failed to reveal the room coverage specs of the air purifier.
They also failed to reveal its CADR and ACH ratings. But we have figured out an apparent calculation of CADR based on DP04 specs.
From the specs, Dyson DP04 delivers 77 gallons of air per second (~ 617 cfm) with the help of the loop amplifier, which multiplies the air up to 15 times than it takes from the base (which passes through the filters). So, we can find out the maximum CADR (Clean Air Delivery Rate) by dividing the total airflow rate by 15, which is approximately 42 cfm. The CADR contributes about 7% of the total airflow.
From an air purifier perspective, the filtration rate is pretty slower than a regular air purifier. However, with the help of the high airflow and oscillation, it will circulate the air effectively inside the room.
With a CADR of 42 cfm, it will clean a 160 square feet room twice per hour. As such, it’s suitable for your bedroom, kid’s room, and kitchen, where you can enjoy a cool breeze with gradual air filtration.
However, if your primary concern is faster air filtration in a medium to large-sized room, then Dyson Dp04 won’t help you much.
Suitable Room Size for Dyson DP04:
- 320 sq ft with one air changes per hour.
- 105 sq ft with three air changes per hour.
If you have higher ceilings, then use our Air Changes per Hour Calculator to calculate the suitable room size.
Dyson DP04 Operating Costs:
Annual Filter Replacement: $79 per year for the HEPA and the Carbon filter (check availability & filter price on Amazon).
Monthly Energy Consumption: ~ $1.7 (based on 12 cents per kWh and 12 hours use on top speed per day). Use our Energy Usage Calculator to find out the bill based on your usage and the local energy rate.

Final Thoughts
Dyson DP04 is a smartly-designed air purifier fan that comes with numerous features and automation opportunities. The airflow is weaker than a conventional fan, and the clean air delivery rate also less than a regular air purifier. However, if you are looking for a combination of an air purifier and a fan with state-of-the-art technology and design, then Dyson DP04 could be a perfect choice for you.
