Dyson never ceases to impress me


I've been using the machine for a week now. I really love Dyson products because of its reliable performance and innovative design, and this machine has all of that. I also own the hot+cool link and compared to that one the cryptomic is quieter, it's taller and slim. I really like the new reverse airflow feature especially at night, it keeps purifying the air but you don't feel it blowing it directly at you. The machine also heats up really quick and depending on the room size it's a really good way to heat a space with purified air. I own 2 cats and I live close to the main street, it's amazing how the machine can immediately detect the pollutants and the monitor lets you know when air quality is back to normal. I have noticed that the air quality has improved in my apartment, the 350 oscillation is a great feature to purify the air in the entire space. The real-time data that is on the machine, as well as the app, allows you to know what type of pollutants are present in your household. A friend of mine was vaping in the room and the machine immediately picked up the smoke and type of particulate matter, it was fun and interesting to visualize how and when the air quality dropped back to normal. I highly recommend this product, I've noticed fewer allergies throughout the day and especially in the morning. It is really useful if you also have pets, it also clears the air quickly if you've been cooking. Overall I really like this air purifier. If you're looking for a reliable and good air purifier for your space plus a beautiful design, this is it. Who doesn't love clean air?

Particles and gases pollute the air when painting

Homes can be up to 5X more polluted than the air outside²

Many household items – from decorating materials, to flooring, to plants – can release microscopic particles and gases. This includes formaldehyde, which can quickly build up and keep polluting for over a year.

Potentially harmful, particles and gases can be found throughout the home, these include…

  • PM 10

    Pollen and allergens
    from plants and flowers

  • PM 5.0

    Bacteria and

  • PM 2.5


  • PM 0.1

    Ultrafine particles
    and viruses

  • Formaldehyde

    Carpets, rugs
    and flooring

  • Odors

    Household fumes
    and cooking

  • Benzene and VOCs

    Cleaning products
    and scented candles

  • Nitrogen Dioxide

    Gas stoves and
    car exhausts

Harmful particles and gases, including formaldehyde.

Formaldehyde is 500X smaller than PM0.1

It's a potentially harmful chemical, emitted by numerous household products. It's particularly difficult to capture, and can pollute continuously.

Dyson Cryptomic™ technology destroys formaldehyde at a molecular level¹

Dyson Cryptomic™ technology has a unique catalytic coating, with the same structure as the Cryptomelane mineral. Its billions of atom-sized tunnels are the optimal size and shape to trap and destroy formaldehyde, breaking it down into tiny amounts of water and CO2.

Automatically senses and reports particles and gases, in real time

With three intelligent sensors, the Dyson purifying fan heater automatically detects airborne particles and gases – including formaldehyde. The built-in LCD screen shows your room temperature, and which pollutants your machine has detected.³

Dyson Pure Hot+Cool Cryptomic with its ceramic heating plates and thermostat exposed

Fast, safe, efficient heating

Self-regulating ceramic plates are positioned at the front of the amp, to heat the air as it leaves the machine. As the plates heat up, they conduct less electricity to help ensure they don’t overheat.

Thermostat control

Once your target temperature is reached, the machine automatically stops heating, which saves energy. If the temperature starts to drop, it reactivates to maintain it.

Powerful Air Multiplier™ technology

Air Multiplier™ technology delivers over 79 gallons of smooth, powerful airflow per second – circulating purified air throughout the whole room.⁴

Dyson Pure Cryptomic purifier with its air apertures and valve mechanisms exposed.

Two airflow modes

The machine has two separate apertures, to release air from either the front or back of the machine. The valve mechanism turns a rotational baffle around the arc of the amplifier, to switch the direction of the airflow.

  • Stream of purified air in fan mode

    Fan mode

    Delivers a powerful stream of cooling, purified air from the front of the machine.

  • Airflow diverts through the back of the fan in diffused mode

    Backwards airflow mode

    In Backwards airflow mode, the unique Dyson air valve projects air through the back of the machine. To purify without cooling you.⁶
