Frequently Asked Questions: Dyson Air Purifiers

What distinguishes Dyson air purifiers from other manufacturers?

Dyson’s air purifiers clearly stand out compared to the devices of other manufacturers. The reason for this is, on the one hand, 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 again justified by their outstanding performance:

Air purifiers from Dyson free the ambient air from up to 99.95 percent of all pollutants, making them extremely efficient. In addition, they are extremely energy-efficient and save electricity. As a user, you also benefit from the easy 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 volume reduction measures.
  • Asthma and allergy friendly certificate for products suitable for allergy sufferers
  • Aha! Allergy Center Certificate for products suitable for allergy sufferers

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

What are the alternatives 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.
Possible alternatives can be

  • Fans
  • Fan Heaters
  • Humidifiers

In the following, we will briefly introduce the individual alternatives for you in more detail.


The first type of device that should come to your mind in terms of affecting the indoor climate is fans.

Since the record summers, they became a must-have for the office and home to escape the stinging heat.

Dyson became famous for designing fans without rotor blades. Visually, they strongly resemble air purifiers.

Fan Heater

The counterpart to the fan. It is used wherever the temperature should be increased simply and easily without heating.

Dyson fan heaters are also similar to air purifiers and fans without rotor blades. Dyson, in terms of design, is unrivaled and especially visually outshines old-fashioned devices other manufacturers.


Like the classic fans, humidifiers are also designed as a device for use in heat and dry conditions. They are useful for you if you are in a room with low humidity for a long time.

Humidity can affect the comfort climate in the bedroom and thus has an impact on the quality of sleep. The ideal humidity level is between 40 and 60 percent. To achieve the ideal humidity, the use of various ventilation devices can be helpful.

In fact, too low humidity has a negative impact on physical health. Most humidifiers have a water tank from which moisture is released into the environment as a fine spray.

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

The filter is replaced in the same way for most Dyson air purifiers. Only the Dyson Pure Hot+Cool and Cool Me require a slightly different procedure.

Dyson recommends changing the filter about every six months. This should also correspond with the device’s visual indicator.

However, depending on the degree of contamination, the frequency of replacement can vary somewhat. You can order new filters from Dyson itself or purchase them from various online stores.

What pollutants does a Dyson air purifier filter?

As mentioned above, 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.

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

  • PM 10: Pollen and allergens from plants and flowers.
  • PM 5.0: bacteria and mold spores
  • PM 2.5: Industrial fumes
  • PM 0.1: 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 stoves and cooking fumes

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

Where should I place the Dyson air purifier?

First and foremost, it depends on which Dyson air purifier you own. Table 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 motors with high air flow can also be sufficiently shown off.

Unsuitable installation locations are, for example:

  • Corners of rooms
  • Near furniture
  • Near walls

In order for Dyson air purifiers to capture all of the air in the room, you should give them enough room to maneuver. To do this, you should keep at least one meter away from obstacles.

It is best to place the device in the middle of the room.

Types of Dyson Air Purifiers

If you want to buy a Dyson air purifier, you can choose between four different models.

  • Dyson Pure Cool
  • Dyson Pure Cool Me
  • Dyson Pure Cool Link
  • Dyson Pure Hot+Cool

In which aspects they differ and which advantages and disadvantages they have, we want to bring you closer in the following descriptions.

Dyson Pure Cool

The Dyson Pure Cool is available as a tower or table fan, depending on your needs and available space. It has a significantly low noise level compared to the other Dyson air purifiers.

The great thing about buying a Dyson Pure Cool is that you are not only buying an air purifier with the device, but you can also operate it as a fan at the same time.


  • Tower and table version
  • Lowest noise level
  • Air purifier and fan in one device


  • Inadequate as a fan
  • Most expensive device (together with Dyson Hot+Cool)

Unfortunately, the fan function of the Pure Cool proves to be insufficient in practice and cannot keep up with a classic fan. The high purchase price of the device also proves to be a negative point.

Together with the Dyson Hot+Cool, this air purifier is the most expensive in Dyson’s product range.

Dyson Pure Cool Me

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 thus be moved around the home without much effort.

The focused air output also ensures that the Cool Me doesn’t mess up any sheets when placed on a desk, for example.


  • Cheapest device
  • Light weight
  • Focused air output


  • Lower airflow
  • Lack of app control
  • No LED display

Due to its compact size, Dyson’s Cool Me unfortunately also has the lowest airflow rate. For the relatively lowest price, Dyson also forgoes some features 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.

Dyson Pure Cool Link

As with the already presented Pure Cool, Dyson also presents you with the choice between tower and table version for the Pure Cool Link, which can be useful depending on the apartment space.

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.


  • Tower and table version
  • Space-saving despite height
  • Air purifier and fan in one device


  • Inadequate as a fan
  • High volume level

Unfortunately, this function is also not very convincing in the Dyson Pure Cool Link. Here, a pure fan is the better alternative.

In addition, you have to be prepared for a very high volume level at maximum power with this air filter from Dyson.

Dyson Pure Hot+Cool

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 any season. On top of that, it’s easy, self-explanatory to use, which makes switching between the three different setting options a breeze.


  • Air purifier, fan heater and fan in one device
  • Simple handling


  • Most expensive device (along with Dyson Pure Cool)
  • Heaviest
  • Highest volume level

However, 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 division.

It is also the heaviest in terms of weight. As a prospective buyer, you should also not shy away from the device’s high volume level.

How To Pick The Best Dyson Air Purifier?

Dyson air purifiers come in a wide variety of designs. The individual product variants can be distinguished on the basis of the following criteria:

  • Filter type
  • Maximum room size
  • Performance
  • Noise
  • Alignment of the air distribution

In the following paragraphs, we will explain exactly what is important for the individual criteria.

Filter Type

Most air filters are equipped with a so-called HEPA filter. So are the models from Dyson presented here.

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

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 percent of all pollutants in the environment.

In addition to HEPA filters, the following other types of filters are available across manufacturers:

  • Pre-filters
  • Active carbon filters
  • Photocatalytic filters

The best filtering results are achieved by combining individual filters in each case.

In the case of Dyson Pure air purifiers, it is the interplay of HEPA and activated carbon filters that makes the device particularly useful for allergy sufferers.

Maximum room size

When buying an air filter is important to choose one that is suitable for the existing size of the room. Only in this way the purification of the air in the entire room is also ensured.

A look at the air purifiers from various manufacturers shows that the range is mainly focused on either smaller rooms up to 20 m2 or larger rooms from a size of about 35 m2.

Dyson’s product range is located in the upper midfield across devices in each case 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 in terms of 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 devices should be suitable for rooms of up to 20 m2.

The room size thus 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 devices depends in particular on the factors of performance and the orientation of the air distribution, which we will examine in a bit more detail.


Two key variables you should look for in terms of an air purifier’s performance are:

  • Power output: is expressed in watts (W).
  • Maximum air flow rate: is given in liters per second (l/s).

The two quantities are highly dependent on each other. You can remember as a rule of thumb:

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

Only sufficient power of the air purifier guarantees the removal of all pollutants present in a room.

In order to decide which power is sufficient for the room in which you want to have the air purified, 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.


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

The noise level is centrally influenced by the performance values of the respective device. The higher the air throughput is to be, the less a certain working volume of the device can be avoided.

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: 40 decibels and above

Dyson is keeping a low profile with volume information for most of its models. Overall, however, the Pure Cool Link and especially the Pure Hot+Cool models are considered particularly loud.

A volume of up to 60 dB can be expected for air purifiers from Dyson.
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 ones for the smaller devices like the Pure Cool Me.

After all, Dyson has recognized the problem and improved the devices in terms of their noise level over the years. For this, the company also received the Quiet Mark Award for several of its devices, as already mentioned.

In addition, Dyson’s air purifiers are equipped with a night mode. During the night mode, the devices work much quieter, so that the do not disturb while sleeping. Accordingly, you can assume a maximum volume of 25 decibels.

Alignment of the air distribution

For the optimal air intake and air distribution, the respective possibilities of the device adjustment are important for you. It is also important if you want to filter the air in the room, but do not want to be disturbed by a draft.

The Dyson air purifiers all have a rotating mechanism that allows individual angle adjustment. This differs depending on the size of the device.

The Cool Me is also equipped with a special dome mechanism that allows the airflow to be adjusted individually.

This allows the handy device to operate undisturbed on the desk.
