Dyson Purifier Hot + Cold Formaldehyde review – stay warm or cool with clean air


The Dyson Purifier Hot + Cool Formadehyde can improve the air quality in your home and thereby the health of your family – it’s well worth the investment if you or your loved ones have allergies and other sensitivities.

We’re spending more time than ever before at home so it’s important to keep the air quality high and the latest Dyson Purifier Hot + Cold Formaldehyde can do just that.

And as its name suggests, the new Dyson unit is strong enough to filter formaldehyde – and that’s a big deal because it is more prevalent than you think.

Formaldehyde is a colourless gas pollutant that can be found in insulation, paint, wallpapers, varnishes and household cleaning products.

It is also actually released by furniture and wooden products containing formaldehyde-based resins like plywood and fibreboard.

So there’s a good chance there’s formaldehyde in your home.

But formaldehyde particles are 500 times smaller than particles the size of 0.1 microns so filtering them is really hard.

But Dyson has cracked the code with the Dyson Purifier Hot + Cold Formaldehyde.

For those wondering, formaldehyde can cause a variety of irritations including eye, nose and lung irritations.

Tech Guide took a closer look at the Dyson Purifier Hot + Cold Formaldehyde which we set up in our living room.

The product is a nice medium size that’s large enough to cool and heat efficiently but small enough to carry to any room in the house.

We paired the unit through the Dyson app so we could not only control the device with our smartphone but also see information like air quality, the temperature and humidity.

Using the app means users can control the device from anywhere on their network so they can turn it on from another part of the house.

For example, the unit may be in your bedroom and you are able to turn it on before you go to sleep so by the time you get to bed, the room is at the right temperature for you.

Many people are under the false impression that the air quality inside their house is clean but the truth of the matter is there are numerous household pollutants in the air.

These include formaldehyde, benzene, nitrogen dioxide, industrial emissions along with pollens and allergens, bacteria as well as other fumes and cooking odours.

And being inside your home, these pollutants have nowhere to go.

The Dyson Purifier Hot + Cold Formaldehyde multiplier technology draws in pollutants and then projects the purified air throughout your living space.

There are four sensors onboard including a dedicated solid-state formaldehyde sensor, which uses a unique algorithm to precisely diagnose the air quality before reacting and purifying the air.

The onboard HEPA+ carbon filter can capture gases and 99.9 percent of particles that are as small as 0.1 microns.

Then the catalytic filter comes into play to destroy formaldehyde as well.

The unit traps formaldehyde and then converts it into water and CO2 through this catalytic filter.

And the good news is this filter is self-regenerating so it will never need replacing.

All of the filters are located in the base of the unit and are really easy to access and install once you take it out of the box.

The Dyson Purifier Hot + Cold Formaldehyde also prevents the pollutants leaking back into the air thanks to the seals that meet HEPA H13 standards.

But it’s not just a filter and a purifier, it can heat and cool the room as well.

The onboard air multiplier technology makes light work of circulating heated and cooled air throughout the room.

Users can set an ideal temperature as well as the fan speed and once that is reached the unit automatically maintains that level.

While it does heat the average size root quite well, larger spaces take a little bit more time.

The unit has to work a lot harder in those larger rooms and, as you’d expect, isn’t as consistent as having the product in an average-sized room.

If you want to warm yourself up using the Dyson Purifier Hot and Cold Formaldehyde it works quite well if you are in its path and sitting close to it.

We found that sitting a couple of metres away we could feel the air coming from the unit but the stream had lost its warmth by the time it reached us and the air was colder than we expected.

Generally if the unit is kept in a corner of the room it will provide consistent heating and maintain it even on those really cold nights.

At the higher fan speeds the unit can be a little noisy if you are sitting close to it but generally it made a non-intrusive background noise.

The included remote control makes it easy to set it to the right temperature and control the airflow.

Having the Dyson Link app puts that convenience in your hand with your smartphone and also makes it possible to control the unit with your voice.

The Dyson Purifier Hot + Cold Formaldehyde is priced at $999 which is a lot more expensive than rival products but the Dyson easily outperforms those other products in terms of airflow, heating and cooling and the sheer level of filtration which now includes that elusive formaldehyde.

Because it can improve the air quality in your home and thereby the health of your family – it’s well worth the investment if you or your loved ones have allergies and other sensitivities.
