What’s New?

How does the Hot+Cool Cryptomic compare to the older Hot+Cool HP04? The one big difference comes down to one thing — 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.

It’s incredibly small (500 times smaller than PM0.1) and can be difficult for traditional air purifiers to trap and eliminate due to it’s small size.

Why is it dangerous?

High levels of formaldehyde in the air is linked to higher levels of cancer or respiratory issues.

Although there are dangers to overexposure of formaldehyde, it’s important to also note that this chemical naturally breaks down in the air (usually within a matter of hours).

The Dyson HP06 Cryptomic is designed to trap and destroy formaldehyde with a technology that directly targets the molecular structure of the chemical.

It uses oxygen in the air to regenerate itself so the plate will never need to be replaced—a really remarkable technology for air purification.

Aesthetically, it looks similar to the other models in the Pure Hot+Cool and is relatively compact in size.

The HP06 would be considered a desk-sized air purifier, about half the size of the taller TP06, which is a tower-style purifier.

There are two colors available of the HP06:

  • Black + Bronze
  • White + Bronze

The Controls

You can control the Hot+Cool Cryptomic using four different methods:

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

#1. Display Screen

At the base of the Hot+Cool is a round display screen that shows indoor air quality and current fan speed.

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 allows you to easily adjust settings on the HP06 as needed. When not in use, the remote magnetically attaches to the top of the purifier, giving it a safe spot to be stored.

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

If you want a truly hands-free way to control the Dyson Hot+Cool HP06, consider voice control. This technology pairs with the Dyson Link app and allows you to control the purifier remotely when partnered with:

  1. Amazon Alexa
  2. Apple Siri

Simple voice commands can be used to change airspeed, air direction, or mode.

The Filters

Filtration on the Pure Hot+Cool Cryptomic is basically the same as the filtration on other Pure Cool Dyson models.

The filter comes in two parts:

  1. 360° Glass HEPA filter
  2. Activated carbon filter
Dyson TP04 air purifier filters

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.

Size & Dimensions

The Dyson Cryptomic HP06 air purifier is basically the same size as the HP04, the model that preceded the HP06.

The exact dimensions are listed below:

  • 9.8″ diameter
  • 30.1″ tall
  • 12.46 lbs

Accessories & Parts

Parts and accessories for the HP06 include all the basic things you need to get up and running, but not much more.

What’s in the box?

  • Dyson HP06 air purifier
  • Power cord
  • 360° Glass HEPA filter
  • Activated charcoal filter
  • Remote control

As mentioned above, the formaldehyde plate is not removable so you won’t have to worry about installing or replacing that piece.

Dyson 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

Smart control is a big part of the overall usability of the Dyson HP06. By pairing the device with your smartphone or tablet via the Dyson Link app, you can quickly and easily see additional details about the status of the purifier.

In addition, the app also stores information about the indoor and outdoor air quality of your environment.

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.

Dyson Link App remote screen

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.

Optional voice control with Alexa (3rd generation Echo Dot shown)

The Dyson app communicates a lot of details about the indoor and outdoor air quality and it organizes the information on a timeline scale.

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 includes three general operating modes.

  • Auto Mode: When in Auto Mode, the HP06 will automatically switch back and forth between fan, heat, and varying levels of air purification. You can assign a target temperature which will adjust between fan and heat. Also, as the indoor air quality fluctuates, the purifier will adjust as needed.
  • Custom Mode: Custom mode offers 10 different fan speeds and custom airflow direction either forward or backward. You can also customize airflow direction, oscillating up to 350° around the base.
  • Night Mode: Night mode is essentially sleep mode, as it’s designed to dim the lights on the display and run at its quietest fan speed. You can also set a timer to run from 1-8 hours (2-hour intervals available).

Air Quality Assessment

Dyson’s ability to determine the indoor air quality at any given time is one of the HP06’s most desired features and for good reason. Showing this data on the air purifier itself (and additional details in the app) makes easier to see the exact impact that the Dyson is having in the space.

It also can provide peace of mind for users who want to ensure that the air they’re breathing is as clean as it can be.

Dyson’s air quality full report can be viewed in the Dyson app, but the display screen on the air purifier itself, making it easy to cycle through quick highlights.

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

Dyson Performance

So above all else, how does the Dyson Pure Hot+Cool Cryptomic actually perform?

To test performance we use the air purifier in our actual home… with actual dirty air. I have a dog, a wife, and a baby. We have additional environmental factors as well like any other home.

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
air quality index - PM 2.5 particulate matter index

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

  • PM 2.5: 7.4
  • PM 10: 12.1
  • Particles: 599
  • AQI: 30

After 1 Hour

  • PM 2.5: 0.2
  • PM 10: 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

When it comes to setting up and using the Dyson Pure Hot+Cool HP06, it’s pretty simple. This purifier comes pretty close to being pre-assembled when it arrives in the box. The basic steps for setup include:

  • 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.

For a more customized cycle, you can install the Dyson smart app and pair the device to your smartphone, which enables some additional features and data about the 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

To keep the Dyson Pure Cool Cryptomic HP06 running smoothly, there are a few simple tasks to do.

Cleaning Dyson Pure Cool air purifier
Maintenance Task #1 – Wipe down the amp
  1. Regularly wipe down the amplifier and filter shroud. Use a lint-free, dry cloth to wipe down outside and inside of the amplifier. This helps to ensure that air can freely flow through the amp.
  2. Follow the prompts when the TP06 tells you it’s time to replace the filter. Regularly checking and replacing the filter as needed is an important part of air purifier maintenance. You can also open the app to review filter status at any point.

Is the Dyson Pure Hot+Cool HP06 a good value?

So overall, is the Dyson Pure Cool Cryptomic HP06 a good value?

The answer to that question really depends on how important formaldehyde removal is to you.

The price is certainly higher than its predecessor, the Hot+Cool HP04, without really changing anything else between the two models besides the colors and the formaldehyde plate.

For homes that have detected high levels of formaldehyde or if you are exposed to high levels at your workplace, addressing (and removing) this chemical could be a top priority.

For those users, the value of the HP06 is better.

But if you are simply looking for a top-of-the-line air purifier that addresses common household allergens, dust, and other airborne debris, the HP04 would likely be a better value.
