  • Hi and thank you for tuning in today.

  • My name is Charlie Park and I'm the Global Category Director for Environmental Care at Dyson.

  • And I'm here today on Oxford Street in London at the Dyson Demo Store

  • to talk to you about some of the new exciting technology that we're launching today.

  • Now at Dyson, any new category that we want to get into,

  • we always want to make a step change in product performance

  • by using new technology.

  • And in this store, you'll see many products which you may already be familiar with.

  • So over here we have our hair care range, with machines such as the Dyson Corrale.

  • The cordless straightener that uses flexible plates to ensure that the hair is corralled and doesn't

  • see excessive temperature so it limits damage to the hair when straightening.

  • And over here we've got our floorcare range, including our Dyson V11

  • our most powerful, intelligent cord-free vacuum cleaner.

  • And here we have our environmental care range of purifiers.

  • A heater purifier, a humidifier purifier and our tower purifier.

  • And that's why I'm really here today, to talk to you about

  • new technologies that we're launching within this category.

  • Now over the course of the last year, we've all spent a lot

  • more time at home as a result of the COVID-19 pandemic.

  • We spend up to 90% of our time indoors.

  • Our homes have become our workplaces, our schools,

  • our gyms and every day we breathe up to 10,000 litres of air.

  • So to put that into perspective

  • this balloon has about 14 litres in it.

  • So, 10,000 litres?

  • That's a lot of air.

  • Now we've all become aware of air quality as a result of the pandemic.

  • But what people are often still not aware of are the other sources of air pollution that are within your homes.

  • So, if you're cooking or cleaning, if you've got pets or you have flowers and plants that give off pollen.

  • But also, air pollution can come in from outside, so if you have an idling car or, in our case here today

  • a big red bus outside, fumes can come in and get caught in your home.

  • And the same, if you live near any building construction work that is going on, you can get particulates

  • that come into your home and get trapped there.

  • So, I'm here today to talk about our latest technology in the Environmental Care category.

  • We're here to launch some brand new purifiers, with some brand new technology within them.

  • So, I'm really pleased today to be able to introduce to you:

  • The Dyson Purifier Formaldehyde range.

  • Now these machines still have the Dyson iconic look and they look very similar on the outside

  • but they are packed full of new technology.

  • They still can sense and capture particulates and VOCs and project clean air.

  • But they now can also sense and destroy formaldehyde.

  • On top of that, we've improved the sealing of the machines

  • so these machines are now HEPA sealed

  • so you get HEPA H13 grade filtration through the whole machine

  • so not just filters, that's the whole machine.

  • And this machine, is 20% quieter.

  • I'm going to now introduce you to Ben, who's one of our senior design engineers

  • who's going to talk you through some of the technology in this product in more detail.

  • Benover to you.

  • Thanks Charlie.

  • Hi everyone, yes, my name is Ben and I am one of the design engineers here at Dyson.

  • Now as Charlie explained there, these new products have still the capability of sensing, capturing and projecting

  • and I'm going to tell you a little bit more about the new technology that's gone inside of them.

  • So, they still senseand they sense things like PM2.5 and PM10 – from pollen, pet dander, smog.

  • They sense VOCs from things like cleaning products inside the home, and maybe candles.

  • And they also sense NO² or city pollutants from things like the bus outside.

  • But they can now also sense formaldehyde.

  • Now they still capture, and they still capture things like your particulate matter and they still capture your VOCs

  • but now we can also destroy the formaldehyde.

  • So first I'm going to tell you a bit more about the sensing technology that's changed here.

  • By introducing our new sensor for formaldehyde.

  • It's a solid-state formaldehyde sensor

  • which is hidden just behind these two slots that are additional to the previous product.

  • Now, the solid-state sensor has been designed specifically

  • to sense formaldehyde and what we need to do

  • is put that formaldehyde into context for you.

  • Why should you care about the formaldehyde, what is formaldehyde?

  • Now formaldehyde is a potentially harmful VOC or gaseous pollutant.

  • It's found in the home more prevalently than outside and it might get sealed and trapped inside of your home.

  • Now that's because it's also emitted from everyday items

  • that me and you are all familiar with that you find in your home.

  • Pressed wood products, like plywood, furnishings, beds, couches.

  • And if you've put a new kitchen in recently, had a kitchen re-fit

  • you might have more formaldehyde in the home.

  • If you have added new furniture to your home recently

  • again there may be more formaldehyde from that product in your home.

  • Painted, varnished, new flooring.

  • All of these things might increase that level of formaldehyde in your home.

  • So, now we know what formaldehyde is

  • we need to understand how it is that we have developed this sensor

  • and what technology we've put into the product.

  • So, when we were developing this new formaldehyde sensor

  • we were looking at lots of different formaldehyde technologies

  • to try and judge which one was best.

  • Now, our solid-state sensor was put into the same chamber as several alternative sensors.

  • Now, when they were in this same chamber together what we found is that the other electrolyte sensors

  • were very easily fooled into thinking other things, other VOCs

  • or commonly found chemicals in the home were also formaldehyde.

  • Now, if we put something as simple as orange peel into a chamber with both of these sensors.

  • What we'll see is our solid-state technology does not react to that orange peel.

  • But, the alternative sensor does react and is easily tricked into thinking that there is formaldehyde present.

  • Now when we're developing these sensors

  • there were several things that we noticed that were improved in performance.

  • They're much more precise than the alternatives.

  • Two, they're much less likely to be fooled by the other pollution that we find in the home

  • those other smells and scents

  • as we've just demonstrated there.

  • And number three, because we're using a solid-state technology and not a liquid or gel-based electrolyte,

  • we keep our performance over time.

  • So, it's more precise, it's less easily fooled, and it also lasts the lifetime of the product.

  • Now, I can imagine you're asking yourselves now

  • now that we can sense that pollution, that formaldehyde

  • and now that we've displayed it on the product

  • so that you know that it's a problem in your home

  • what are we going to do to tackle that pollution source?

  • So, that leads us on to our new technology in this product.

  • We still have that HEPA filtration in the front, along with the activated carbon.

  • The HEPA to remove the particulates and the carbon for the gases.

  • But we now have a third layer, which is this new catalytic technology.

  • It's a Selective Catalytic Oxidation filter and it specifically targets formaldehyde.

  • Now, it utilises the Cryptomelane mineral inside of this filter,

  • which is perfectly shaped with nanoscopic tunnels that are exactly

  • the right shape and size to interact with the formaldehyde molecule.

  • So, when a formaldehyde molecule comes into contact with the surface of this mineral

  • it gives it oxygen and by oxidising it

  • it turns one molecule of formaldehyde

  • into one molecule of CO² and one molecule of H²O, in tiny quantities.

  • So that is simply a small amount of water vapour and a small amount of carbon dioxide and nothing else.

  • So that means that this is not captured.

  • It is not stored in the filter, like you find with other filtration techniques.

  • It is destroyed at a molecular level.

  • And what's more interesting with this still, is that it is constantly replenishing the oxygen on the surface

  • of the catalyst with the oxygen that's readily available in the air.

  • What that means is that you never need to change the filter.

  • This catalytic element of the filter will last the entire lifetime of the product, along with that sensor.

  • So, you can now sense the formaldehyde, you can capture other pollution

  • and you can destroy that formaldehyde at the source.

  • Now, once you've gone through all of those filtration stages

  • the product then uses the motor bucket to increase the pressure

  • in the amplifier to project the air into the room.

  • And as Charlie mentioned earlier, we now have not just a H13 HEPA rating in the filter

  • we have that rating in the entire product.

  • So, if you look at this video now, you'll see what that means in the real world.

  • We have one of our products in a sealed chamber

  • with the inlet and the filters in the bottom part of the chamber

  • and the amplifier on the outside.

  • When we introduce a pollution event into that chamber,

  • the product turns on and begins filtering down that pollution.

  • The machine draws that air through the filters and projects it out through the amplifier.

  • And what you can see is that there is no smoke, dust or any orange left on the amplifier

  • and this is because it has all gone through that filter

  • and all been filtered first.

  • What's more, if you take the filters off of the machine

  • you'll see internal in the machine there is no pollution that has escaped the filter.

  • There is no pollution on the inside of the filter either

  • and on the outside, it's clear that all of that pollution

  • has been trapped in that HEPA layer.

  • Now how did we achieve this H13 level filtration on the entire product?

  • Well what we had to do was go back to basics on this

  • and have our engineers look at every possible opportunity inside of the machine

  • for any bypass of that filtration layer.

  • If you look at this demonstration

  • it shows you that we found 24 different points that could be potential leak paths in the system.

  • We looked at every single one of these in isolation and did individual sealing and leaking tests on each one.

  • If any of them were found to be providing any leak at all, we added in a high pressure seal and adding in seals

  • into every one of these regions, along with the seals that are

  • already on the particulate filter, allowed us to achieve that full-machine HEPA efficiency.

  • So now I'm going to pass you back on to Charlie

  • and he's going to tell you a little bit more about how we achieved a 20%

  • reduction in acoustics on the machine.

  • Charlie, back to you.

  • Thank you, Ben.

  • So how did we make those acoustic improvements?

  • So, at Dyson we have five acoustic chambers in our technology centres, and we are always using them to

  • continually iterate our design, looking for opportunities to reduce the acoustics of our products.

  • So how we've done it, is we've looked for every opportunity

  • to smooth the airflow between the motor and the outlet.

  • By doing this it stops any turbulence, which creates noise but also wastes energy.

  • So, by doing that not only do we stop any noise from the airflow itself

  • but it allows us to drop the motor speed

  • so we reduce the acoustics at the source, being the motor.

  • So, there we have it.

  • The new Dyson Purifier Formaldehyde range.

  • Not only does it now sense and destroy formaldehyde

  • it is H13 level HEPA filtration at whole machine

  • not just filter, and the tower purifier is 20% quieter.

  • All of the information of what the machine is up to

  • with regards to removing pollution is displayed on the LCD screen

  • and can also be seen on the Dyson Link app, where all these machines are connected to

  • which gives you enriched data about the history of what the machine has done

  • with regards to removing pollution.

  • I'm pleased to say as well that we have also developed a commercial variant of these machines,

  • which have all of the same features but will also support ventilation in commercial spaces.

  • So, if you would like to learn more about these machines

  • then please head down to your Dyson Demo store.

  • We have Dyson Demo stores all around the world

  • where you can see the technology on display that I've described today.

  • If you cannot visit a Dyson Demo store at the moment

  • because of local restrictions, then please head to the Dyson website

  • where you can take a tour of a virtual demo store

  • which will show off the technology on these products that we've been through today

  • but also all of these machines in our store.

  • If you would like more information about this specific launch event

  • then also head to the Dyson Newsroom.

  • So, thank you all for tuning in today and stay safe.
