Written By: Dr Fahad Yasin

In the continuous pursuit of elevating the game, Dyson has sculpted an extraordinary device. It’s a beast that’s not only a fan and a heater, but also an air purifier.

The Dyson Pure Hot+Cool Cryptomic HP06 air purifier. At first blush, it’s a compact piece of art that’s fully capable of servicing the indoor atmosphere all year round. But the star of the show, the unprecedented feature of this technological wonder, is its knack for ensnaring and disintegrating formaldehyde particles. And yes, it’s Wi-Fi enabled, offering control via a smartphone app or voice commands.

Let’s dive in and see what’s new!

The Dyson Pure Hot+Cool Cryptomic air purifier is a compact purifier that serves a purpose year-round as it offers a fan, heater, and air purification. The HP06 is also unique in its ability to trap and destroy formaldehyde particles in the air, which can be a common irritant in many households.

  • Traps and destroys formaldehyde along with 99.7% of other particulate over 0.3 microns
  • Heats, cools, and purifies the air
  • Airflow up to 310 liters/sec


  • More expensive than the HP04 model with similar capabilities
  • Limited availability outside of Dyson.com
  • Expensive

What’s New?

So, how does this new kid on the block, Hot+Cool Cryptomic, stand up against the veteran Hot+Cool HP04? The difference, my friends, is elemental, revolving around one key word—formaldehyde.

The Dyson Hot+Cool Cryptomic has an added panel that breaks down formaldehyde into CO2 and H2O and never needs replacing, since it’s built into the machine.

What is formaldehyde?

Formaldehyde is a colorless, odorless chemical found in many household products and building materials and is pretty common in most homes.

Imagine formaldehyde as an invisible, unscented intruder lurking in your home, dwelling within household products and building materials. Its compact structure, 500 times smaller than PM0.1, can slip through the net of traditional air purifiers, making its capture and elimination a tricky task.

Why is it dangerous?

Formaldehyde may be small, but its potency can’t be ignored. High exposure can pave the way for cancer and respiratory issues. Thankfully, it tends to break down naturally in the air within a few hours. 

The genius of the Dyson HP06 Cryptomic is that it’s equipped to capture and annihilate formaldehyde, using a technology that zeroes in on the chemical’s molecular structure. And guess what? It self-regenerates with the help of oxygen in the air, eliminating the need for replacement. That’s air purification at its finest.

Dyson Hot+Cool Cryptomic Design

With a pleasing aesthetic that mirrors other models in the Pure Hot+Cool line-up, the Dyson Cryptomic HP06, despite its compact size, proudly wears the crown of an air purifier, fan, and heater. Its dimensions are akin to a desk-sized purifier, roughly half as tall as the tower-style TP06.

Choose from two tasteful color combinations:


  • Black + Bronze
  • White + Bronze

The Amplifier

Nestled at the top half of the purifier, the amplifier has a streamlined design, devised to draw air through it and thrust it into the room. With its bladeless design, it allows for an air flow of up to 310 liters/second, making it capable of purifying air in rooms of any size.

The Controls

The Hot+Cool Cryptomic offers four different control points:

  1. Display Screen
  2. Remote Control
  3. Smartphone Control
  4. Voice contro

1. Display Screen

The base of the Hot+Cool harbors a round display screen, a silent reporter of indoor air quality and fan speed.

When in Auto Mode, the machine adjusts the fan speed to maintain good air quality. If it senses a dip in air quality, the fan speed ramps up. For manual control, you can use the provided remote control or the Dyson app.

2. Remote Control

The remote control allows you to:

  • Turn the purifier on / off
  • Switch between heat or fan mode
  • Adjust fan speed (1-10)
  • Oscillate base of the purifier (0-350°)
  • Reverse airflow (forward or backward)
  • Turn on the sleep timer
  • Turn on Auto Mode
  • Flip through sensor readings (using the “i” button)

The remote control is your magic wand. The best part? It finds a home on top of the purifier, attaching magnetically.

3. Dyson Link App

Dyson’s smartphone app is a convenient tool, capable of monitoring indoor and outdoor air quality. It also lets you adjust fan speed, switch modes, or make other tweaks to the HP06 purifier, without lifting a finger.

Using the Dyson app you can:

  • Perform all the functions of the physical remote control (listed above)
  • Provides real-time air quality monitoring based on your geographic location (ie. how bad / good the outside air quality is)
  • Provides real-time air quality monitoring based on the sensor data from the Dyson air purifier itself (PM10, PM2.5, VOCs, etc.)
  • Allows you to set an automatic on / off schedule
  • Voice control
  • Provides firmware updates to the purifier

4. Voice Control

For a hands-off experience, the Dyson Hot+Cool HP06 is compatible with Amazon Alexa and Apple Siri, letting you control the purifier with simple voice commands.

The Filters

The HP06 uses a duo of filters that are in line with other Pure Cool Dyson models:

  • 360° Glass HEPA filter
  • Activated carbon filter

Together, these two filters efficiently remove 99.7% of airborne particles, down to 0.3 microns in size.

What about formaldehyde?

While the filters themselves are not able to detect, trap, or destroy formaldehyde, there is a special panel in place specifically for formaldehyde.

This panel is designed to break down formaldehyde into CO2 and H2O and because of it’s molecular structure, it is regenerated by oxygen, so it never needs replacing.

Dyson HP07 Features

For a quick rundown of features, here’s the top 3 categories of what the Dyson Pure Hot+Cool Cryptomic HP06 can do:
  1. Smart Control
  2. Operating Modes
  3. Air Quality Assessment

Smart Control

The smart control capabilities of the Dyson HP06 elevate it to a different plane. When paired with a smartphone or tablet, it offers a wealth of details about the purifier’s status, and stores data about your indoor and outdoor air quality. The cherry on top? The device is compatible with Amazon Alexa devices for voice control.

Wondering if the air purifier is even making a difference?

Charting the indoor air quality is an excellent way to put it to the test and see exactly how much your air quality proves with prolonged use.

Smart control works from your smartphone or tablet, but it also is enabled to work with Amazon Alexa devices, like the Echo Dot or Echo Plus.

Air quality details that the app includes are listed below:

  • Temperature
  • Humidity
  • PM10
  • PM2.5: particulate matter 2.5
  • VOC: volatile organic compounds
  • NO2: nitrogen dioxide

Operating Modes

The Dyson Cryptomic HP06 features three modes:
Auto Mode: Automatically adjusts between fan, heat, and air purification modes based on indoor air quality and a target temperature set by the user.
Custom Mode: Offers 10 fan speeds, custom airflow direction, and oscillation of up to 350°.
Night Mode: Runs on its quietest fan speed and dims the lights on the display.

Air Quality Assessment

The HP06’s air quality sensor is its trump card. It offers a quick look at the air quality on the purifier itself and a detailed report in the app, providing users a snapshot of the device’s impact.

Here’s an example of what the Dyson display could read:


Dyson Performance

The ultimate test of the Dyson Pure Hot+Cool Cryptomic lies in its performance.
During our tests, we’re looking at a couple of different things, but some of the most critical include:

  • Air quality index
  • PM 2.5
  • PM 10
  • Particulate count

How do we test?

When we start the test we use the Temtop LKC-1000S+ professional air quality detector to get a good baseline reading. What is the air quality of the room before running the purifier?
Then we run the purifier for 60 minutes in the room and retest the data using the same air quality detector. The difference between the two measurements is noted and we can start to have a solid idea of how each purifier could be expected to perform in real-life scenarios.

Now, while we haven’t run an actual test of the Dyson HP06 air purifier quite yet, I can say that we have fully tested it’s like counterpart — the Dyson Pure Cool TP04. We’ve included our TP04 data below.

Both the HP06 and the TP04 have the same size and style of filters (360°Glass HEPA and Activated Carbon). The big difference between the two models is airflow. The TP04 can move air at a speed up to 363 liters/second while the HP06 maxes out at 310 liters/second.

  • NOTE: Airflow speed does not equate to room size. Both purifiers can purify small, medium, or large rooms. The difference is the speed in which it will get the job done.

Starting Baseline

PM2.5: 7.4

PM10: 12.1

Particles: 599

AQI: 30

After 1 hour

PM2.5: 0.2

PM10: 0.2

Particles: 14

AQI: 0

Within 1 hour, the Dyson removed 98% of air particulates from the medium-sized room we tested in (approx. 12’x12′). Dyson improved PM 2.5 air quality by 97%.

Setup & Usability

For those who like things simplified and straightforward, the Dyson Pure Hot+Cool Cryptomic HP06 is a godsend. Unlike a complicated piece of software, it’s almost plug-and-play in its operations. Out of the box, it’s nearly ready to embark on its air-purifying adventure.

  • Unboxing the air purifier.
  • Installing the filters and replacing the shroud.
  • Plugging it in.
  • Turning it on.
Pretty basic stuff. Without any additional settings, the HP06 will begin running in Auto Mode and self-adjust to the current air quality conditions.

One push of the power button, and you’re off to the races. The HP06 springs into action, using its intelligence to assess the air quality and adjust its operations accordingly in Auto Mode. It’s not just an air purifier, but a dutiful steward of your indoor air quality.

Control it with the remote control, the app, or your voice. You can customize many features on this purifier including:

  • Airflow speed (1-10)
  • Airflow direction (forward or backward)
  • Oscillation (static or moving / 0 – 350°)
  • Sleep timer
  • Night mode
  • and more

Dyson Maintenance

When it comes to maintenance, the HP06 follows the principle of simplicity. Keeping the machine up and running is about as challenging as wiping down a counter. Literally.

Maintenance Task #1 – The Amp Wipe-Down
Regular maintenance of the HP06 is about as unassuming as it can get. The amplifier and filter shroud simply need a quick rub down with a lint-free cloth to keep them dust-free and air flowing freely. It’s a simple task that helps the purifier to perform at its optimum level.

Maintenance Task #2 – The Filter Check

Regular filter checks are another crucial part of the routine. Thankfully, the purifier itself will let you know when it’s time for a filter change. And if you’re ever curious about the filter’s condition, you can check its status on the Dyson Link App at any time.

A well-maintained HP06, with its filters properly looked after, ensures that the purifier remains in top form, keeping your indoor atmosphere clean and comfortable.
