Dyson Air Purifier Review

You will find plenty of Dyson Pure Cool reviews, but we believe it’s important that you also learn about what makes this fantastic company stand out.

About Dyson

Dyson, a British company founded almost 30 years ago by Sir James Dyson. Currently headquartered in Wiltshire, England.

Since then, it has become one of the most popular home appliance brands worldwide.

Its famously known for its vacuum cleaners, hairdryers, hand dryers, lights, and, of course, air purifiers.

All of its products are exports from the UK and are sold in more than 75 countries globally.

Presently, the company has more than 12,000 employees across many countries, with about a third of whom are scientists and engineers.

Furthermore, it holds more than 7,500 patents worldwide.

Dyson Institute

While Dyson products are known worldwide, not many people are aware of the Dyson Institute of Engineering and Technology.

Sir James Dyson always showed an interest in education. He set up an institute close to the company’s Malmesbury headquarters.

The institute offers a four-year course wherein the students can work and learn at the company’s laboratories and one day a week is set aside for academics.

Until the institute gets its own certification, it offers its students a degree from Warren National University.

The course accepts only 30 students and provides them with hostel facilities.

Who Is the Dyson Air Purifier For?

In a nutshell, the Dyson Pure Cool Purifier can be for anyone who wants to purify indoor air.

However, certain people can enormously benefit from the use of an air purifier more than others.

Consider buying the Dyson Pure Cool Air Purifier if:

You have pets but also suffer from allergies.

Those who have pets at home may develop some form of allergic reaction from pet dander, fur, and hair.

For some, these allergies may be mild. However, for many people, they can be pretty severe.

Having an air purifier in your home can effectively filter these allergens from the air, leaving the air you breathe much healthier and cleaner.

Your house always smells dirty.

Some people are highly sensitive to smells, which can be bothersome and sickening at times.

If your home absorbs smells from soiled diapers, dirty shoes, painting or renovating, and so on, an air purifier can do a great job eliminating these odors, leaving your home smelling fresh.

You suffer from respiratory problems.

Respiratory issues, like asthma, tend to be unpredictable; specific allergens can almost instantly set off an attack.

This can reduce lung function and, in more severe cases, result in an inability to breathe.

An air purifier is made to filter these harmful allergens that trigger asthma attacks, thus improving air quality and providing you with peace of mind.

You live with a smoker.

There have been countless studies showing that secondhand smoke is extremely harmful to humans and can have serious side effects.

Since the Dyson Pure Cool comes with HEPA filters, smoke, tobacco pollutants, and odors are eliminated.

This small appliance can make a massive difference to your health.

What’s in the Box?

The Dyson Pure Cool purifier comes with all the essentials necessary for you to run it right out of the box.

The package will include:

  • Dyson DP04 Air Purifier
  • Power Cord
  • Remote Control
  • Activated Charcoal Filter
  • 360° Glass HEPA filter

Overview of the Features

One of the best air purifiers that have come out from Dyson’s range of air purifiers is the Dyson DP04 Pure Cool.

Let us tell you in detail why so.


The Dyson Pure Cool is one of the most popular and effective air purifiers designed to remove even those ultrafine particles from the air.

What we particularly like about it is its multiple air quality sensors.

These sensors work automatically by first detecting and then alerting you of the presence of any contaminants in the air.

These contaminants can include ultrafine particles at PM 2.5, larger allergens at PM 10, humidity, nitrogen dioxide, and temperature.

You can find all the alerts of the contaminants on the Dyson Link app, which is compatible with both Android and iOS smartphones.

This app is easy to pair with the air purifier and allows you to customize the device’s settings.

The purifier also features Air Multiplier technology, allowing it to deliver about 77 gallons of air every second or about 617 cubic feet of air every minute.

At night, you can set the purifier to Night Mode, and that will dim the LCD.


Weighing a little over 10 pounds, the Dyson Pure Cool is very sleek.

At a height of roughly 27 inches and the plate measuring at a little under nine inches, it is very compact, too.

This small size allows it to be placed in any room you desire.

The base houses the purifier’s LCD, the filtration system, and the intake vent. The entire base is covered with perforated holes.

This design lets it intake much more of the contaminated air from all the sides to purify it.

After the purification process, the air gets redistributed via the loop amplifier. This amplifier has a diameter of about 14 inches, which makes it highly impressive.

The air purifier can be tilted upwards and downwards manually. What’s more, the oscillation angle can be set between 45 and 350 degrees.

This helps in projecting the purified air throughout the room.

You can choose between two colors: white and silver. These elegant colors and its unique design will easily blend with your home décor.

It’s pretty sturdy and durable, too, as it is made using a strong metal.

Multi-Stage Filtration System

The Dyson Pure Cool features a two-stage air filtration system: an activated carbon filter, and a sealed HEPA filter.

The HEPA filter is completely sealed. They also have it available in a 360-degree version.

It can capture and remove up to 99.97% of microscopic pollutants and even allergens as small as 0.3 microns.

These include pollen, pet dander, dust, smoke particles, and others.

The glass HEPA filter features 29 feet of borosilicate microfibers pleated more than 238 times.

After the contaminated air passes through the HEPA filter, it will further move on to the activated carbon filter. There, odors will be absorbed and neutralized.

The filter also helps in removing VOCs and other household odors, too, such as formaldehyde and nitrogen dioxide.

The activated carbon filter is made using high-quality carbon. It is far superior to those you find on cheaper models (typically come with paper coated with carbon).

The air passes through the HEPA filter firts. Then next through the activated carbon filter. Lastly, released into the room through the bladeless air multiplier loop.

The Dyson Pure Cool has been certified by the Asthma and Allergy Foundation of America for being allergy- and asthma-friendly.

Furthermore, it is ozone-free since it lacks a negative ion generator.


Other than the Dyson Link app, the air purifier can also be controlled via the remote control or Alexa and Siri.

A great thing about the remote is that it has a magnetic base. This will allow it to attach itself to the top of the machine. Reducing the possibility of losing it.

However, the standout feature here is the sensor kit.

Unlike several other air purifiers (which typically come with just one sensor), the Dyson Air Purifier uses three different sensors for gases, humidity, and temperature.

For the best experience, this comes with Auto and Sleep modes, but what sets it apart is the Diffused mode.

With this, the purified air will come through the back instead of the front so that it doesn’t hit you directly.


While the company does not exactly state the purifier’s coverage, upon testing, we found that it works best in a 300-square-foot room.

That said, we believe that with its maximum airflow of 77 gallons per second would also make it ideal for use in medium to large spaces measuring up to 600 square feet.

Noise Output

When you use the purifier on its highest fan speed, it records a noise output of about 57 dBa.

This level of sound can be compared to the sound of heavy rainfall.

On the other hand, the sound is barely audible when set at the lowest fan speed, making it ideal for use during sleep.

Power Consumption

The Dyson Pure Cool is one of the most energy-efficient air purifiers on the market at present.

It has a power rating of 4-32 watts, costing you a mere $12 annually if you run it for eight hours a day.


The air purifier itself does not need much maintenance. You just need to wipe it down whenever needed.

The only important maintenance requirement is to replace the air filters as on a regular basis.

The company recommends changing the filtration kit every year using the Dyson Replacement Sealed 2-Stage 360-Degree Filter System.


The Dyson comes with a two-year warranty on the air purifier. Along with a generous 30-day money-back guarantee in case you are not satisfied with the product.


  • Excellent removal of air contaminants
  • Highly accurate air quality sensors
  • Fairly quiet operation
  • Combines air purifying and fan
  • Sleek design
  • Works with Alexa and Siri


  • Does not support Google Home
  • Pricier than other non-Dyson models

Dyson Air Purifier FAQs

1. How long do Dyson air purifiers last?

Air purifiers can last for a very long time, depending on how you use it.

The more important question is how long the filter lasts.

While the app does indicate when you need to change your filter, the duration can differ depending on where you live.

For instance, if you live in the city, you would have to change the filter every six to seven months.

In a slightly less polluted area, the filter can be used for up to a year.

2. Does Dyson Pure Cool actually cool air?

No, the Dyson Pure Cool will not cool the air in your room.

It’s simply called “Pure Cool” because of its forward-airflow that gives a chill feeling as you would get in a fan.

3. Can filters be washed, Instead of replacing them?

No, the activated carbon and HEPA filters aren’t washable.

You will have to buy a replacement from the company itself when and as needed.

We hope that our Dyson Air Purifier review has given you all the information you need to make this purchase.
