Dyson DP04 Air Purifier: Trusted Review & Specs

If not for the obvious display on the front, we may mistake this Dyson DP04 with any air purifier in the Dyson Pure Cool Link series. Well, the design maybe doesn’t change, but the internal power of this Dyson DP04 is, by far, better than any other low-end models in its series. We are going to make a separate Dyson DP04 Review to help you find out the best desktop Dyson Pure Cool for now.

Dyson DP04 ranks B- in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:

• We provide honest reviews (both pros and cons) so that everyone can make the best decisions.
• We do not (and never will) exaggerate one product just to let you click the links and buy that product blindly.

The Dyson Pure Cool Link is one of the first inventions for air purifying by Dyson, the leading company in making products that control the indoor air quality. The Dyson DP04 is the new model, and whether you have the old Dyson Pure Cool Link or not, you really should read our today Dyson DP04 Review.

Dyson DP04 Price

Our previous Dyson Pure Cool Link was released after other models like the Dyson Pure Hot+Cool or Dyson Pure Cool Tower, so even the DP01 model is packing with the hottest additional features like Wi-Fi capability and Alexa Voice Control.

Of course, the Dyson DP04 must be better than the previous models, but that’s not really a surprise – it’s the new one. The bigger question is: what’s actually changed, given the design is so similar to last models. Well, the air filter is upgraded and more powerful, the features are richer and we can notice the actual indoor air quality thanks to the bright clear LCD display.

These are all just tweaks though, and it’s smart from Dyson to remove the old Dyson DP01 in its listing page, as that would be a far more attractive option this year. You still can read our review of Dyson Pure Cool Link, and check the deal if you want a cheaper model.

So, this is the Dyson Pure Cool Link Desk DP04, it may look identical to the old ones, and you might think that not a lot has changed – but it’s inside where the differences lie. And for anyone who are in love with the desktop version of Dyson air purifiers, you really need to opt in for the newer model. Yes, because the Dyson DP04 price is only $499 officially, which is just $50 difference from the old DP01. I believe that it’s worth the update, especially when I have a great deal.

It is somehow a more complicated air purifier, just like the competitor Sharp KC-850U, but with fan feature instead of humidifier. You can choose either the Oransi mod or Whirlpool WPPRO2000 for high-quality air filters, but these devices can’t move the airflow as good as our Dyson Pure Cool Link DP04. Or you can search for the overestimated Molekule Air with the exclusive PECO filtration system, that the brand claimed to be “better than HEPA level in every category”.

Dyson DP04 Design and Size

The design of this Dyson air purifier is as impressive as ever, with the cool bladeless amplifier to work as a fan. You will get rid of the traditional fast-spinning fan, or any awkward grills for a safer and easier way to use, as well as clean your air purifier. That’s incredible, right?

To say the Dyson DP04 is a high-end fan is also right. As the desktop version, but with no less than 27 inches in height, the Dyson DP04 can be adjusted manually thanks to the pivots of its body. So you can angle the airflow up and down without the need of its mechanized oscillation settings.

There is also a Blue color option available for the Dyson DP04, which is quite similar to the second-gen flagship Dyson TP02 or Dyson HP02.

This upgraded Dyson DP04 is still taller than the previous Dyson Pure Cool Link, and with the solid metal body, our flagship in the desktop series is firmer and stronger. It is also heavier, with the weight of 10.25 lbs. However, it is still compact enough to let you bring everywhere in your home.

The base of this Dyson DP04 is much taller, and it gives the black bezel and LCD display more attention. The next-gen LCD display is the distinctive feature of any Dyson air purifiers with “04” in the name.

Dyson DP04 sports the same bottom-to-top airflow system concept like any brothers of its family. The air intake is made of perforated holes, to act as a pre-filtration layer before the contaminants contacting the HEPA filter. Under the amp, we will have air outlet to redirect and manage the clean airflow.

Dyson DP04 Filters

As the newer product of the desktop series in Dyson, Dyson DP04 will use the best and latest air filter from this company. It is a better filter, with 2-stage air cleaning system instead of only 1 like the predecessors.

1. True HEPA filter – With the glass HEPA filter, the Dyson Pure Cool Link Desk is able to capture 99.97% all airborne particles as small as 0.3 microns, including pollen, bacteria and pet dander.
2. Activated Carbon filter – Removes household odors and gases such as formaldehyde, benzene and nitrogen dioxide.

The Dyson DP04 will use the latest glass HEPA filter, which has 29-feet borosilicate microfibers, and can guarantee the efficiency of 99.97% for any particles down to 0.3 microns. In fact, the Dyson DP04 is certified by the Asthma and Allergy Foundation of America (AAFA) for asthma and allergy friendly and California Air Resources Board (CARB) for being safety to use. That being said, the air filter is high-quality and 100% ozone-free to use.

Now, we will have a canister of tris-impregnated Activated Carbon filter inside the air filter. It is high-quality carbon, not the paper carbon like low-end products, and you will see the difference in your home almost instantly.

If you still need a proof for the power of Dyson glass HEPA filter, you can see the chart below. In a room of 400 square feet, and for a period of only 1 hour, the Dyson DP04 performed much worse than the top-class air purifiers, like the Vornado PCO575DC, Levoit EverestAir, Oransi mod and Winix XQ.

The best part, our glass HEPA filter is only $10 more expensive than the previous air filter, which is $79 for a set of one genuine replacement filter. You should change the air filter annually for optimal performance.

Dyson DP04 Room Coverage

It is recommended for room of 126 square feet by the Energy Star.

Because this air purifier is also a fan, we don’t have the ACH and CADR ratings. Dyson told that high CADR rating doesn’t mean better, so it doesn’t quote any CADR score for its products.

The ACH of Dyson DP04 is 4X. However, if you are running the air purifier in 400 square feet, expect it to clean for only once per hour.

The CADR of Dyson DP04 is 93 Dust/ 82 Smoke/ 113 Pollen (cfm). It is far too low for an air purifier in this price range. The maximum airflow of Dyson DP04 is up to 77 gallons per second, which is equal to approximately 615 cfm, but this is its cooling fan power. It does help with the Dyson DP02’s air purifying process, but not much.

Dyson DP04 Sound

One more advantage of having a Dyson air purifier is its noise level. Even if you combine the air purifier with cooling function, the noise level is still under control, with the highest speed being only 57 decibels (dB). You can always change the setting and enjoy a much quieter sound.

For a desktop air purifier like Dyson DP04, such noise level is pretty perfect, especially when the highest noise is only white noise, and can help you sleep easier.

Dyson DP04 Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, an air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is good or not.

For an air purifier with fan function, the Dyson DP04 is better than many others in terms of power consumption, which is only from 4 to 32 watts. Its score is only behind the signature air purifier of Rabbit Air – the Rabbit Air BioGS 2.0.

If you run the Dyson DP04 for 8 hours per day, you only need to pay from $1.5 to $12 each year.

Dyson DP04 Additional Features

At last, we’ve come to the most interesting part, why you buy the newer generation of Dyson Pure Cool Link DP04 instead of the previous ones. High-end air purifiers often offer many handy features, to help us use them in a smarter and easier way.

Back to the nature of the Dyson Pure Cool Link, Dyson DP04 has both air purifier and fan functions. That being said, it has 10 different fan speeds to change, depending on your need.

The oscillation setting from previous models is improved in a much better way. Our previous model can only swing for 70°, while the Dyson DP04 can adjust the oscillation up to 350°. Combining with the powerful airflow it projects, Dyson DP04 can easily reach any parts of your room.

Moreover, you may not always be in the warm months, and there will be time that you don’t need the cooling power of Dyson DP04 to kick off. Dyson added the Diffuse Mode to help you reverse the airflow, and as the result, stop cooling. It is a necessary option, one that you should really go for.

There are three main ways to control your Dyson DP04. Be it the remote control, which is magnetic and can stick to any parts of your air purifiers, so you won’t forget where you left it. Of course, the remote control will be packed with more buttons than the minimalism one of old Dyson DP01.

Second, you can control your air purifier via the Dyson Link app. It even gives you the current status of both indoor and outdoor temperature, air quality as well as humidity level. The app can help you schedule the air purifier, or check the filter life whenever you want.

Finally, the Dyson DP04 is a Smart air purifier and you can use Alexa to control it via voice commands. Remember to use short and simple spoken instructions so it can understand your commands. Actually, I don’t value much this function, as I’d like to interact with my device more thoroughly.

In normal air purifiers, you will have a basic dust or smoke sensor, mainly to detect the current air quality changes. However, our Dyson DP04 is one of the few devices to introduce 3 different sensors. The humidity and temperature sensor is the first one, to constantly monitor the relative humidity and temperature within your room. The next one, the particulate sensor uses laser measurement, and can actively analyze the particulate concentration. Instead of the smoke sensor, Dyson’s gases sensor can even track the Volatile Organic Compounds (VOCs) or oxidizing gases.

This Smart Sensor feature will automatically report to you via the LCD display, and if you enable the Auto Mode, the Dyson DP04 can adjust the fan speed to quickly respond to the indoor air quality changes. In just a matter of minutes, and any spray of chemicals will be cleaned. Also, the LCD display will show the indicator for filter replacement, so you don’t need to remember the date manually.

We still have the Night Mode to help dim the display and lower the fan speed instantly, and a basic Timer to schedule the activity of our air purifier.

Dyson DP04 Customer Service

Dyson is one of the best brands for its impressive customer service. Once you are Dyson’s customer, the company promises to help you even after your warranty has ended, which is something that not many brands dare to do.

To reach its support, you can either search for it yourself in the thorough online guides, or you can contact easily with this line: 866-693-9766. If you can’t call the customer service (for example on Sunday), you can email it at questions.us@dyson.com.

Most importantly, you should be Dyson’s customer to have access to its exclusive VIP loyalty programs. Once registered for the warranty, you can enjoy Saving Events to help you save 20% on your next purchase, as well as reminders for free preventative maintenance checks at a Dyson Service Center.

Like many big brands, Dyson provides free shipping for its products. You can return an order with free shipping as long as you are within the 30-day money-back guarantee. This could be one of the most generous offers for refunds among any air purifier brands.

Dyson only has a 2-year warranty for both labor and parts on its air purifiers. For such expensive air purifiers, the warranty is a bit short.

Our verdict

First generation of Dyson Pure Cool Link is not that good in our ranking list, and the Dyson DP04 is just better with smart features. We don’t recommend to get the unit if you need a serious air purifier.
