Do you suffer from poor air quality in your home or office? Are you also an allergy sufferer? Then an air purifier is a must for you. Admittedly, many air purifiers are anything but visually appealing. This is where the attractively designed air purifiers from the manufacturer Dyson come into play.

In our Dyson air purifier test 2021 we would like to introduce the Dyson air purifiers in more detail. You will receive important information about the different types, as well as the factors you should consider before buying. With the help of our test article, you should be able to find the right Dyson air purifier for you.




Summary

  • With Dyson air purifiers, you can distinguish between the Pure Cool, Pure Cool Me, Pure Cool Link and Pure Hot+Cool models. They vary in terms of functionality, size and performance.
  • Key factors that should play a role in your purchase decision are, above all, the type of filter used in the device and the room size it supports.
  • Depending on the intended use, fans, fan heaters or humidifiers can be a suitable alternative to air purifiers. Here, too, Dyson offers devices in each case.

The Best Dyson Air Purifiers: Our Choices

Guide: Questions you should ask yourself before buying a Dyson air purifier

Before buying a Dyson air purifier, you should acquire some background information. We have summarised this information in the following paragraphs.

What makes Dyson air purifiers different from other manufacturers?

Dyson's air purifiers clearly stand out compared to the devices of other manufacturers. On the one hand, this is due to their innovative and unique design. On the other hand, they also stand out from other manufacturers in terms of price. However, their high price is justified by their outstanding performance: Air purifiers from Dyson remove up to 99.95 percent of all pollutants from the ambient air and are therefore extremely efficient.

In addition, they are extremely energy-efficient and save electricity. As a user, you also benefit from the simple operation via remote control and smartphone app. In addition, Dyson has received several awards and accolades from independent institutions for its products. These include:

  • Quiet Mark Award for product noise reduction measures
  • Asthma and allergy friendly certificate for products suitable for allergy sufferers
  • Aha! Allergy Centre Certificate for products suitable for allergy sufferers

They were awarded respectively for the following Dyson air purifiers:

Award/Certificate Dyson Pure Cool Dyson Pure Cool Me Dyson Pure Cool Link Dyson Pure Hot+Cool
Quiet Mark Award
Asthma and allergy friendly Certificate
Aha! Allergy Centre Certificate

We will talk about the individual models and what exactly distinguishes them later in the decision section.

At what prices are Dyson air purifiers sold?

As already mentioned, Dyson air purifiers are among the more expensive air purifiers. The products are fairly evenly distributed over a price range of 40 to 400 euros. Therefore, from an overall perspective on HEPA air purifiers, the chart shows that air purifiers are available for every budget. You can get an air purifier for less than 50 euros.

HEPA: High-efficiency particulate air.

A Dyson air purifier, however, is in the upper price range with a minimum price of about 300 euros. Depending on the model, you can spend well over 650 euros for a Dyson air purifier.

What alternatives are there to Dyson air purifiers?

Dyson, as well as numerous other manufacturers, offer other types of devices in addition to their air purifiers for the purpose of individual manipulation of the indoor climate. Depending on the purpose of use, you may find an alternative to the air purifier that is suitable. Possible alternatives can be:

  • Fans
  • Fan heaters
  • Humidifiers

In the following, we briefly present the individual alternatives in more detail.

Fans

The first type of device that comes to mind in terms of influencing the indoor climate are fans.

Since the last record summers in Germany, they have become an absolute must-have for the office and the home to escape the stinging heat. Dyson became famous for designing fans without rotor blades. Visually, they look a lot like air purifiers.

Fan heater

The counterpart to the fan. It is used wherever the temperature needs to be increased simply and easily without heating. Dyson fan heaters are also similar to air purifiers and fans without rotor blades. In terms of design, Dyson is unrivalled and outshines other manufacturers, especially in terms of appearance.

Air humidifier

Like classic fans, humidifiers are designed to be used in hot and dry conditions. They are useful for you if you are in a room with too little humidity for a longer period of time. Humidity that is too low has a negative effect on your physical health. Most humidifiers have a water tank from which moisture is released into the environment as a fine spray.

Decision: What types of Dyson air purifiers are there and which is the right one for you?

If you want to buy a Dyson air purifier, you can choose between four different models. In the following descriptions, we will tell you more about the differences between them and their advantages and disadvantages.

What is the Dyson Pure Cool and what are its advantages and disadvantages?

The Dyson Pure Cool is available as a tower or table fan, depending on your needs and the space available. It has a significantly low noise level compared to the other Dyson air purifiers. The best thing about buying a Dyson Pure Cool is that you not only get an air purifier, but you can also use it as a fan at the same time.

Advantages
  • Tower and table version
  • Lowest volume
  • Air purifier and fan in one device
Disadvantages
  • Insufficient as a fan
  • Most expensive device (together with Dyson Hot+Cool)

Unfortunately, the fan function of the Pure Cool is inadequate in practice and cannot compete with a classic fan. Another negative point is the high purchase price of the device. Together with the Dyson Hot+Cool, this air purifier is the most expensive in Dyson's product range.

What is the Dyson Pure Cool Me and what are its advantages and disadvantages?

With the Pure Cool Me, Dyson sends its affordable air purifier into the race. The handy air purifier also scores best on the scales and can therefore be moved around the home without much effort. The focussed air output also ensures that the Cool Me doesn't mess up sheets of paper when placed on a desk, for example.

Advantages
  • Cheapest device
  • Lightweight
  • Focused air output
Disadvantages
  • Lower air throughput
  • Lack of app control
  • No LED display

Due to its compact size, the Cool Me from Dyson unfortunately also has the lowest air throughput. For the relatively lowest price, Dyson also forgoes some functions with this air purifier. The app support of the other devices is missing, and the practical LED display of the other models is also not included.

What is the Dyson Pure Cool Link and what are its advantages and disadvantages?

As with the Pure Cool already presented, Dyson's Pure Cool Link gives you the choice between a tower and table version, which can be useful depending on the space in your home. In its significantly higher tower version, the Cool Link surprises with its space-saving footprint, which is no larger than an A4 sheet of paper. Here, too, you buy an air purifier with fan function.

Advantages
  • Tower and table version
  • Space-saving despite height
  • Air purifier and fan in one device
Disadvantages
  • Insufficient as a fan
  • High noise level

Unfortunately, this function is not very convincing with the Dyson Pure Cool Link either. A pure fan is the better alternative here. In addition, you have to be prepared for a very high noise level at maximum output with this air filter from Dyson.

What is the Dyson Pure Hot+Cool and what are its advantages and disadvantages?

With the Pure Hot+Cool, Dyson goes one better. Besides the optional fan function, you can even use the Hot+Cool air purifier as a fan heater. The device is therefore suitable for all seasons. In addition, it is easy and self-explanatory to use, which makes switching between the three different setting options child's play.

Advantages
  • Air purifier, fan heater and fan in one device
  • Easy to use
Disadvantages
  • Most expensive device (together with Dyson Pure Cool)
  • Heaviest
  • Highest volume level

But the scope has its price: the Dyson Pure Hot+Cool, together with the Pure Cool, is the most expensive Dyson product in the air purifier category. It is also the heaviest in terms of weight. As a prospective buyer, you should also not shy away from the high noise level of the device.

Buying criteria: You can use these factors to compare and evaluate Dyson air purifiers

Dyson air purifiers are available in a wide variety of models. The individual product variants can be distinguished according to the following criteria:

  • Filter type
  • Maximum room size
  • Power
  • Noise level
  • Orientation of air distribution

In the following paragraphs, we explain exactly what the individual criteria are.

Type of filter

Most air filters are equipped with a so-called HEPA filter. This is also the case with the Dyson models presented here.

1 micron = 0.001 millimetre, accordingly: 0.1 micron = 0.0001 millimetre.

It is the main component of the filter technology used and filters particles down to a size of 0.1 micron from the air. According to the manufacturer, this corresponds to around 99.95 per cent of all pollutants in the environment.

In addition to HEPA filters, there are the following other filter types across manufacturers:

  • Pre-filter
  • Activated carbon filter
  • Photocatalytic filters

In the following, we have summarised the individual filter types and their respective filter function for you in a table. We would also like to show you which filter types are used in Dyson's devices:

Filter type Filter function Lifetime With Dyson
Pre-filter -Coarse dust particles -Hair Long-lasting, as washable
HEPA filter -Bacteria -Fine dust particles and toner dust -Small suspended particles -Allergens -Pollen and pollen -Tobacco smoke Six to twelve months
Active carbon filter -Organic molecules -Harmful gases -Odours Six to twelve months
Photocatalytic filter -Bacteria and gases Long-lasting, as self-regenerating

The best filter results are achieved by combining individual filters. In the case of the Dyson Pure air purifiers, it is the combination of HEPA and activated carbon filters that makes the device particularly useful for allergy sufferers.

Did you know that one micron is 0.001 millimetres? You won't have much idea of what that means. Therefore, for comparison: One micron is one hundredth of the thickness of a sheet of newsprint. It is one twelfth of the thickness of aluminium foil.

Maximum room size

When buying an air filter, it is important to choose one that is suitable for the available room size. This is the only way to ensure that the air in the entire room is cleaned. A look at the air cleaners of various manufacturers shows that the range is mainly concentrated on either smaller rooms up to 20 m2 or larger rooms from a size of about 35 m2.

Dyson's product range is in the upper midfield in the product class of smaller to larger rooms.

Dyson recommends its devices for a room size of up to 43 m².

Thus, they do not take the top position with regard to the supported room size. While Dyson recommends its more powerful devices for room sizes up to 43 m2 , the company unfortunately does not provide any data for the smaller devices.

However, a comparison with other manufacturers shows that the entry-level units should be suitable for rooms of up to 20 m2. With regard to room size, this results in the following performance spectrum for Dyson's air purifiers:

High-end: Dyson Pure Cool, Pure Cool Link, Pure Hot+Cool

Entry-level: Dyson Pure Cool Me The room size supported by the units depends in particular on the factors of power and the orientation of the air distribution, which we will examine in more detail.

Power

Two key variables you should look at in terms of the performance of an air purifier are: Poweroutput: is expressed in watts (W). Maximum air flow rate: is given in litres per second (l/s). The two quantities are strongly dependent on each other. You can remember as a rule of thumb:

The higher the specified power, the greater the maximum air flow.

Only a sufficient power of the air purifier guarantees the removal of all pollutants in a room. In order to decide which power is sufficient for the room in which you want to purify the air, the height of the room plays a decisive role in addition to the room area.

Thus, the required maximum air flow rate of the unit can be determined mathematically. Below we have compiled an overview of the specified air flow rates of the individual Dyson air purifiers. We compare this with the suitable room volume and the suitable room area.

Dyson unit Flow rate (l/s) Flow rate (m³/h) Room volume Room area
Pure Cool tower 360 l/s 1,300 m³/h 130 m³ 50 m²
Pure Cool table 440 l/s 1.580 m³/h 160 m³ 60 m²
Pure Cool Me 170 l/s 610 m³/h 60 m³ 20 m²
Pure Cool Link Tower 410 l/s 1,480 m³/h 150 m³ 60 m²
Pure Cool Link Table 330 l/s 1,190 m³/h 120 m³ 50 m²
Pure Hot+Cool 290 l/s 1,040 m³/h 100 m³ 40 m²

The calculation confirms our assumption from before, which we had to make due to the lack of manufacturer information. Dyson serves room sizes between 20 and 60 m² with its air purifiers and thus even exceeds its own specifications of a maximum of around 40 m². For the calculation we proceeded as follows:

  1. Conversion of air flow rate (2nd column) from l/s to m³/h (3rd column).
  2. Division by a factor of 10, as we assume that the air is heavily polluted. This gives the room volume (4th column).
  3. Division by 2.5, as we assume a room height of 2.5 m. This gives the room area (5th column).

Noise level

A factor that should not be neglected when choosing an air purifier that is suitable for you is its noise level. An air purifier that is too loud can be extremely annoying in the long run.

When used in the bedroom, the volume of an air cleaner is all the more relevant. A night mode enables low-noise use during sleep. (Image source: unsplash.com / elizabeth lies)

The noise level is centrally influenced by the performance values of the respective device. The higher the air flow rate is to be, the less it is possible to avoid a certain working noise level of the device. In general, air purifiers can be divided into the following volume levels depending on the decibel number:

  • Quiet: up to 25 decibels
  • Medium: 25 to 40 decibels
  • Loud: from 40 decibels

Dyson is cagey about the volume level of most of its models. Overall, however, the Pure Cool Link models and especially the Pure Hot+Cool are considered particularly loud.

A volume of up to 60 dB can be expected with Dyson air purifiers.

With a stated volume of over 60 decibels, the Dyson Pure Cool, which is considered much quieter in comparison, is also already very loud. Accordingly, higher values are to be expected for the larger models, and correspondingly lower values for the smaller devices such as the Pure Cool Me.

At least Dyson has recognised the problem and improved the devices over the years with regard to their noise level. For this, as already mentioned, the company received the Quiet Mark Award for several of its devices. In addition, the air purifiers from Dyson are equipped with a night mode. During the night mode, the devices work much quieter so that they do not disturb your sleep. Accordingly, you can expect a maximum volume of 25 decibels.

Alignment of the air distribution

For optimal air intake and air distribution, the respective options for adjusting the unit are important for you. It is also important if you want to filter the room air but not be disturbed by a draft. The Dyson air purifiers all have a rotating mechanism that allows for individual angle adjustment.

This differs depending on the size of the device:

Unit type Models Angle adjustment
Larger units -Dyson Pure Cool -Dyson Pure Cool Link -Dyson Pure Hot+Cool 45 to 350 degrees
Smaller units -Dyson Pure Cool Me Up to 70 degrees

The Cool Me is also equipped with a special dome mechanism that allows the airflow to be adjusted individually. This allows the handy appliance to operate undisturbed on the desk. Dyson shows a short overview of the air distribution of the Pure Cool Me in one of its product videos:

Facts worth knowing about Dyson air purifiers

Now that you've gathered enough information about Dyson air purifiers, we'd like to conclude by giving you some more information. If you already own a Dyson air purifier, you may find some valuable tips here.

How and how often should I change the filter on my Dyson air purifier?

The filter is replaced in the same way on most Dyson air purifiers. Only the Dyson Pure Hot+Cool and Cool Me require a slightly different procedure. We have summarised the individual steps for you below:

Dyson Pure Cool, Pure Cool Link Dyson Pure Hot+Cool Dyson Pure Cool Me
Replacement indicator = The visual display of the appliance informs you when the filter needs to be replaced. =
1. = Disconnect the appliance from the mains. =
2. Remove the air ring by pressing the two outer buttons. Remove the two elements of the outer casing by pressing the two outer buttons. Remove the top element by pressing the two outer buttons.
3. Remove the filter housing and dispose of the old filter. Remove the filter from the corresponding outer casing by pressing the two purple buttons. Pull the filter out of the main unit using the tab.
4. Insert the new filter into the housing and place the housing back on the main unit. Dispose of the old filter. =
5. Re-engage the air ring. Insert the new filter into the corresponding outer sleeve. Insert the new filter into the main unit.
6. Connect the appliance to the mains. Reattach the two outer casings to the main appliance by latching them in place. Reattach the top element by latching it in place.
7. Press and hold the on/off switch on the remote control for about six seconds until the LED display shows a circulating charging pattern. Connect the unit to the mains. =
8. = The air purifier can be used normally again. =

Dyson recommends changing the filter about every six months. This should also correspond with the visual indication of the device. However, depending on the degree of contamination, the frequency of replacement may vary somewhat. You can order new filters from Dyson itself or from various online shops.

What pollutants does a Dyson air purifier filter?

As already mentioned, Dyson air purifiers can filter around 99.5 percent of all pollutants from ambient air down to a size of 0.1 microns with the help of their HEPA filter.

But what exactly are these pollutants?

According to Dyson, Dyson air purifiers remove the following pollutants:

  • PM 10: Pollen and allergens from plants and flowers
  • PM5.0: Bacteria and mould spores
  • PM2.5: Industrial fumes
  • PM0.1: Ultrafine particles
  • Formaldehyde: carpet, floor mats and floors
  • Greenhouse gases: mainly carbon dioxide
  • Benzene and volatile organic compounds: Cleaning products and scented candles
  • Nitrogen dioxide: Gas cookers and cooking fumes

As you can see from this overview, the filtering of ambient air by Dyson air purifiers covers the complete range of pollutants produced in the home.

Where should I place the Dyson air purifier?

First of all, it depends on which Dyson air purifier you have. Tabletop models like the Dyson Pure Me are simply placed near you at table height. For the other air purifiers that are placed on the floor, the question of where to place them is even more important. They should be placed in such a way that their high airflow motors can be used to their full advantage. Unsuitable locations are, for example:

  • Corners of rooms
  • Near furniture
  • Near walls

To ensure that Dyson air purifiers can capture all the air in the room, you should give them enough room to manoeuvre. To do this, you should keep at least one metre away from obstacles. It is best to place the device in the middle of the room.

How do I connect the Dyson air filter to the Dyson Link app?

Apart from the Dyson Pure Cool Me, all other air filters are app-compatible. With the Dyson Link app, you get extensive features for your air filter. Highlights of the Dyson Link app include:

  • Remote control of the air filter
  • Up-to-date air quality reports
  • Creation of schedules
  • Checking the life of the filter

and much more. But how can you connect a Dyson air filter to the Dyson Link app? Dyson provides an app for both Android and iOS users. This is connected to the device as follows:

  1. Download the app from Google Play/ from the Apple App Store.
  2. Open the app.
  3. Sign in with your Dyson account. Create an account if you do not already have one.
  4. Press and hold the on/off button on the device for about five seconds until the LED flashes green.
  5. Connect the air purifier to the network via the app.
  6. The connection process begins. The LED now lights up white until the device is successfully connected.
  7. Assign a name for the air purifier using the app.
  8. The device is now ready for use!
