Dyson Pure Cool Air Purifier Review

Dyson Pure Cool Air Purifier Review

As someone said, Dyson can definitely be called the Apple of air purifiers. With elegant aesthetics, thoughtful features and sophisticated technology, Dyson air purifiers stand apart from the rest.

In this article, we take a look at the features, its filters, performance, pros and cons of the Dyson Pure Cool Air Purifier.

Whom Is It For?

Dyson Pure Cool Air Purifier is meant for you, if you live in any of the highly polluted cities with undesirable levels of PM ( Particulate Matter) 2.5 and PM 10. It could be especially useful if you have a relatively larger space to purify, like a large bedroom, office space, conference room or living room as large as 600 Sq. Ft.

Now, even if you don’t live in any of those cities with bad air pollution, but suffer from asthma or allergy due to dust or pollen, then you are highly likely to find a relief in symptoms with Dyson Pure cool air purifier. In fact, all Dyson air purifiers are Certified Asthma and Allergy friendly by the Asthma and Allergy Foundation of America.

As per the manufacturer, Dyson Pure Cool air purifier is effective for spaces as large as 600 Sq. Ft.

Shunning the CADR ( Clean Air Delivery Rate) method adopted by most manufacturers, Dyson uses the POLAR method whereby they test their air purifiers in a larger 27 square meter space with nine air quality sensors across the room. Then, they measure the PM levels throughout the room to ensure that air across the entire space is purified and not just the immediate space around the air purifier.

We tried using the air purifier in our living room of about 600 Sq. Ft for the past 7 days. The results were more than satisfactory. We always run the air purifier on Auto mode as the place we live in is not quite polluted. As we have an open kitchen, the Air Quality Index often shoots up while cooking. At that time, the air purifier increases its fan speed automatically for cleaning the air quicker. Usually, in a matter of just 15-20 minutes, the Air Quality Index comes back to the level “Good”.

To further test the air purifier, we lit two Agarbatti in our bedroom of about 150 Sq. Ft. After completely burning them, the PM 2.5 shot up to 104 and PM 10 to 120 as per our air quality sensor. The Dyson Link app showed PM 2.5 level as 99, which is classified as Very Poor.

We switched on the air purifier to Auto mode and oscillation to 350 degree. Sensing by the sound level, as expected, the air purifier was running at its maximum speed.

Within 11 minutes, the air quality index changed from Very Poor to Poor. The PM 2.5 level fell to 42 and PM 10 to 48.

Within another 5 minutes, the PM 2.5 and PM 10 level was 34 and 39 respectively and the air flow speed was reduced a bit.

Within the next 8 minutes, the Air Quality Index turned to level “Good” with PM 2.5 and PM 10 levels as 34 and 39 respectively.

Final measurements were taken at the 30 minute mark and by then the levels were down to 21 and 24.

Overall, there is no doubt that the air purifier is quite efficient. Within less than 30 minutes it was able to turn the air with very poor AQI to the level good. We also noticed that oscillation stopped while changing the functions or checking the air quality parameters using the remote and resumed once we stopped using the remote. This is rather thoughtful as you don’t have to move along to change the settings while oscillation is on.

Due to certain limitations, we were unable to test the air purifier in a larger space. However, we will be doing that in the coming days and shall update the article with the findings.


The Dyson Pure Cool Air Purifier looks quite modern and stylish. Though it may look delicate, it is made of high quality ABS material that doesn’t break easily. Even if the air purifier falls, the body might get some scratches, but won’t be damaged beyond that.

With 1 metre height and weighing less than 5 Kg, the unit is quite susceptible to falling. So, if you have small children at home, you might have to be extra careful about keeping the air purifier out of their reach.

Talking about the design, the power button is above the cylindrical base and it also has a colorful LCD panel that displays useful information like real time Air Quality Index ( AQI), PM 2.5, PM 10, VOC, NO2, temperature and humidity.

Along with the air purifier, you do get a handy remote controller which is magnetized so that you can place it on top of the air purifier while not in use. It is quite a thoughtful design as you are more likely to keep it in the designated spot and not misplace it– something that is bound to happen with a small remote controller.

The remote has to be pointed at the display panel for it to function. But if you want to control the air purifier from elsewhere, you can do so with your smartphone by installing the Dyson Link app and connecting the air purifier to Wi-Fi.


As mentioned earlier, Dyson Pure Cool Air Purifier has a real time display showing essential air quality parameters. They can be checked in more detail through the Dyson Link mobile app too.

The air flow can be adjusted using the remote or app to 10 different levels depending on your need. Or you can opt for Auto mode which uses fuzzy logic to analyse the indoor air quality and adjust the air speed accordingly.

An important aspect of Dyson Pure Cool Air Purifier which other air purifiers don’t have is that it can oscillate up to 350 degrees thereby taking in impure air and throwing out pure air in all directions. Oscillation can be set in 45, 90, 180 and 350 degrees.

Night mode is a feature that could be especially useful for light sleepers who get disturbed by even minute noise. When activated, the air purifier works at comparatively lower airflow level of 1 to 4 to reduce the noise, all the while effectively purifying the air.

The diffused mode is an option that is useful for those who operate the air purifier in cold climate, say for example, in the cold Delhi winters. In this mode, the air purifier works at high efficiency, but the air is thrown out in a diffused manner by reducing the air multiplying effect. This way, the room is not cooled further. This feature is not seen in the previous Dyson Pure Cool Link Tower Air Purifier.

Many ask whether the Dyson Cool Air Purifier can replace an air cooler. Unfortunately NO. When set at the maximum air flow speed of 10, it provides a gentle cool breeze which is pretty soothing when you sit very close to the air purifier. But if you sit 1 to 2 metres away from the air purifier, you are hardly likely to experience the gentle breeze. So, while the air flow is indeed cool, it doesn’t really act as a replacement for an air cooler, especially if you live in cities like Delhi where summers are scorching.


The Dyson Pure Cool Air Purifier has 360 degree filters which the company claims to be highly effective in purifying all types of air contaminants.

Inside the air purifier, there is a motor that sucks in the air from all sides. The air first passes through the heavily pleated Glass HEPA filter made of Borosilicate. Dyson claims it uses Grade 13 HEPA filter which is capable of absorbing 99.95 % of microscopic allergens and pollutants as small as 0.1 microns.

Air that is purified through the HEPA filter is then passed through the activated carbon filter which absorbs odours and other VOC ( Volatile Organic Compounds). What we found when we compared the carbon filters of Philips and Dyson Pure Cool  is that the latter is far denser with lesser gaps.  It is also thicker than the carbon filter of Dyson Pure Cool Link Air Purifier.

Each filter comes in two pieces which is fixed around the motor in 360 degree and then locked. Something we really liked is that the filter is completely sealed, that is, it has a gasket around itself which ensures no air leakage. So, the air doesn’t pass through without going through the two filters.

Each filter lasts for 4300 operating hours irrespective of the level of pollution in your space.

Dyson Link App

Pairing the air purifier to the Wi-Fi and the mobile phone app is pretty easy and your service agent too can assist you with it.

The app shows not only the indoor air quality parameters, but also how it fares in your city. It can take care of all functions that the remote controller does and you can view the graph of how the air quality ranges on a daily and weekly basis. Additionally, you can create a weekly schedule to run the machine at specific time in settings of your choice.

The app makes managing the air purifier and its settings quite easy. In fact, Dyson and Mi are the only brands that offer app connectivity to air purifiers as of now.


As mentioned, the filters have a life of 4300 hours. As per the service technician, it is advised to clean the HEPA filter using a dry cloth or to vacuum clean it every 4-6 months to enhance the filter’s performance. You can know the level of filter life using the Dyson Link app.

New Glass HEPA filter as well as activated carbon filter costs about Rs. 2490 each. You can buy them through Dyson website or through Amazon. And as with most other air purifiers, it is quite easy to replace the filter that you won’t have to depend on a technician. I wouldn’t be exaggerating saying it can be done by even a 5 year old because mine did!

Common Complaints

We asked the service technician about the common complaints they see. We were told that people often forget to clean the filter in between and see a drop in the air purifier’s efficiency and complain about it.

Next, the adapter might get damaged if you live in a comparatively older building where voltage fluctuates drastically. So, you might have to connect to a UPS or stabilizer in such a situation. Otherwise, technical problems or damages are hardly reported.


Dyson launched in India just 2 years back. So, we may not find many user reviews talking about durability. However, if you take a look at amazon.com, you do find highly positive reviews with hardly any complaints about the long term performance.

Also, Dyson is known to abuse its products as a part of testing it. They drop it, slam it, jump on it and undertake a lot of tests to analyse its performance over life time and are quite committed to selling only the best. So, you needn’t really worry about the durability. And even if in case you encounter any problem, the sales support team is quite prompt and keen to help.

Flaws, But Not Deal Breakers

Honestly, we can’t really find any flaw with its performance. The air purifier is quite efficient at cleaning the air quickly. Agreed that it is a bit too expensive, but the design and efficiency makes it worthy. Also, No Cost EMI options are available through Amazon as well as Dyson website to ease the burden.

Design wise, we just found that the adapter seems to be a bit too large that it fell off the UPS a few times.

Also, as mentioned earlier, the unit seems to be a susceptible to falling especially if you have small kids at home who might climb on it. So, you will have to keep it out of their reach.


With thoughtful design, sophisticated appearance, user friendly features like Wi-Fi connectivity, real time AQI index, and above all, efficient performance, Dyson Pure Cool Air Purifier is definitely an alluring air purifier.Though expensive, the No Cost EMI options offered could make it within reach for those who need a high quality air purifier for their well-being.

Overall, if you value the ease of use, transparency and durability that Dyson offers, then you won’t be disappointed investing in the Dyson Pure Cool air purifier.
