Dyson Purifier Hot+Cool Formaldehyde review

(Pocket Ribbon) – Putting the word “Formaldehyde” in a product’s title is audacious, especially when it follows “Hot+Cool,” suggesting there are two types of formaldehyde it could be sending you.

Of course it’s not: thanks to the word “Purifier” also in the name, you can rest assured that this product aims to eliminate formaldehyde rather than sucking you in with it slowly.

There’s a similar model – the Dyson HEPA Purifier Cool Formaldehyde – that feels the same, but again, it doesn’t blow cold formaldehyde at you, it cleans the air.

As with any high-end Dyson model, the price is much higher than a conventional fan. So, is it worth spending more? We tested it to find out.



Our quick review

The Dyson Purifier Hot+Cool Formaldehyde offers a wide range of air treatments – and the performance is outstanding.

The full range of hot and cold functions, as well as purge options, are immediately appealing, but the need for all of these functions will depend on your situation.

With a full range of options – and a full range of prices – there are units further down the scale that will give you many of the basic experience and features (cooling and air filtration) at lower prices.

However, the Dyson Purifier Hot+Cool Formaldehyde certainly gives you the full package. If you work in an outdoor office or live in a high-rise building where you can’t open the window, this unit can give you the versatility you’re looking for.

While we tend to call them fans (at least in the UK), Dyson’s ‘air handling’ products now go way beyond the simple airflow provided by a fan. Hence some comical names trying to spell out the functions of this device.

For this particular model, we have purification – an H13 HEPA filter system – which also detects and destroys formaldehyde, heating and cooling. In general, the more features, the higher the price.

The design is now iconic, as easily recognizable as Dyson vacuum cleaners, and certainly reach the highest level of desirability. Everyone has a tower fan, but if you have a Dyson fan, there’s something more stylish in the corner of the room.

This signature design includes the base, which houses the motor, and, in the case of air purifier models, the filters that feed the oval head, which is leafless. It’s one of the most attractive aspects of Dyson machines: there are no moving parts on the outside for you to stick your fingers in.

This model also has a tilting base so you can tilt it up or down slightly, and an oscillation function that, like the Dyson tradition, is smooth and quiet.

The head is double-sided, allowing air to be blown out of the front or indirectly from the back of the unit, while a front display shows a relative status graph relative to the air-purifying capabilities the fan offers.

There is also a remote control, which attaches magnetically to the top of the fan. As you’d expect, it does some controls, while others are offered in the Dyson Link app. The remote stays firmly in place, but it’s easy to drop and lose, but it’s possible to buy a new one (thankfully).

We should also say that the finish scratches quite easily and starts to look a bit worn over time.

Features and Performance

  • 290 l/s airflow
  • 10 different speed settings
  • 0.1 micron filtration
  • Dyson Link app,= ; Alexa integration

There are many different features that this single “fan” offers. With many different models in the Dyson range, you might be better off choosing a different model if you don’t think you need all of those. There are models that provide heating only, others with cooling and heating, and still others with or without purge.

Since the pandemic, there has been a little more focus on air quality and filtration, but the usefulness of HEPA filters goes back much further. The idea is that all the air in the room can pass through the filter to draw out bacteria, viruses, pollen and other pollutants — including formaldehyde — before being expelled again.

This can be especially good for those who can’t open the window – such as those who live in a building with closed windows, or for allergy sufferers who can’t open the window during the day or night due to pollen-induced hay fever.

The reality is that poor air quality is more common in the winter, because we keep all the windows closed, or we use other heaters, and the air doesn’t circulate as freely. That is why it is certainly attractive to have these purification options all year round. Indeed, if all you want to do is circulate the air to cool you down, the Dyson Cool tower may be a better option: with no filter, you have to think about less.

The screen on the front of the HP09 gives you a graph of the current air quality and as long as the machine is plugged in it can monitor the air quality. You can then access all this information by pressing the “i” button on the remote and scrolling through the details.

The Dyson will also identify what has been detected – PM2.5, PM10, VOC, NO2, HCHO – so you can get a better idea of ​​what could be the source of this poor air quality. Particles can be pollen or dust from other sources such as soot, while traffic or furniture processing can increase things like volatile organic compounds.

To tackle VOC there is an activated carbon mat, while for formaldehyde there is a catalytic filter that breaks it down. The latter never needs to be replaced, unlike HEPA and carbon filters, which need to be replaced. Again, an indicator in the app tells you the remaining life of your filters, as well as how to order a new one.

Outdoor air purification, the ability to blow hot or cold air offers great versatility, especially in a space such as an outdoor office where there may be no heating systems. Cooling is gentle and powerful and works on a scale of 1-10.

There’s also a night setting that lets you put it on this scale at 4, which is a level where it’s not too loud, so you can imagine what it’s like at level 10.

As we mentioned above, there’s also a diffusion option, which pushes the air backwards instead of the precision jet up front. This means you can clean the air without blowing it in your face, which is a great option for winter.

Oscillation is also very impressive, as you can choose the degrees you want to rotate by pressing the remote. This means you can point it where you want it, instead of twisting it to blow air into an empty space that no one can take advantage of.

It’s all executed with a level of sophistication that surpasses that of other fans. This is obviously an expensive item, but if you want a well-designed piece of equipment rather than an industrial eyesore then Dyson is definitely here for you.

It’s smart too, allowing you to connect to services like Alexa so you can use voice commands via an Amazon Echo, for example.

What it doesn’t do is monitor air quality remotely and turn it on when the quality drops (you could probably control this with a separate Alexa-enabled air quality monitor), but you can run it in automatic mode, which adjusts the fan power. according to air quality. If you start frying something in the kitchen, the Dyson will react and start blowing air, removing the contaminants until it’s happy they’ve been removed.

summarizing

The Dyson Purifier Hot+Cool Formaldehyde is a feature-rich air treatment option. Many will just want the ventilation and filtration options (but there are cheaper options that will serve you better), while the connectivity means you can use voice commands and use your smartphone to control this unit. Its full range of options makes it ideal as an all-in-one device, so for a high-rise apartment or a garden office, it could be all you need in summer or winter.
