Dyson Air purifier Large+Quiet Formaldehyde: Two-minute evaluation
January 2024: The Dyson Air purifier Large+Quiet Formaldehyde was initially solely out there within the US and Australia, however one mannequin is now out there within the UK as properly. We have up to date the worth part of this evaluation to mirror that.
It was not love at first sight with the Dyson Air purifier Large+Quiet Formaldehyde, however after simply someday of utilizing it in my own residence, I don’t need to ever be parted from it – sturdy phrases for a relatively huge and hulking air purifier fan, however I stand by it. It’s utterly totally different from any of Dyson’s earlier residence purifiers – when it comes to each design and performance – though it shouldn’t be confused with the HEPA Large+Quiet that’s particularly for industrial areas.
Like its identify suggests, it’s huge and it’s quiet. It’s been made to flow into clear air in giant rooms whereas standing in a nook as an alternative of within the heart of an area to be at its best. Dyson says it will probably service areas which are as much as about 100sqm / 1,000sqft in measurement, projecting filtered air as much as 10m. Furthermore, the angle of the propelled air could be adjusted (there are three to select from), so it doubles up as a strong fan as properly which, at full bore, isn’t louder than 56dB.
Dyson has adopted cone aerodynamics to greater than double the Coanda impact the model makes use of in its different purifiers. In accordance with the British model, this enables the Large+Quiet to course of as a lot as 87 liters of air per second. This can be a arduous metric to measure, so I’m taking Dyson’s phrase on this, however it’s simple to imagine in the event you occur to be within the path of the propelled air.
At this level, I feel it’s essential to level out that there are two Large+Quiet Formaldehyde fashions recognized by their coloration schemes. For this evaluation I used to be despatched what’s the Dyson-exclusive mannequin and is costlier as a result of it has an extra CO2 sensor and a second filter inside (see the worth part beneath for extra particulars). I discovered the CO2 sensor very helpful as you possibly can by no means inform if your private home wants ventilating or not. I used to be just a little horrified at how rapidly CO2 can construct up in an area – if I go away my home windows closed for about an hour for any motive, the CO2 ranges can go from beneath round 400ppm (which is sweet) to about 1,500ppm (which isn’t that good). If left in Auto mode, the Large+Quiet will dynamically change its fan pace to flow into the stale air however that’s additionally a sign that it’s essential open some doorways or home windows as excessive CO2 ranges could cause fatigue, complications and lack of focus.
What the 2 fashions share are an entire bunch of different sensors that detect a number of widespread pollution, together with mud, pet dander, pollen and formaldehyde (emitted from a number of family merchandise together with new furnishings and mattresses), as properly NO2 (nitrogen dioxide) from automobile fumes and unstable natural compounds (or VOCs) from aerosol sprays like deodorants. These are then filtered by a HEPA filter that complies with the H-13 customary, the best score for a purification system. Which means that the Large+Quiet has a fully-sealed filtration system that may seize as much as 99.95% of air particles as small as 0.1 microns, and Dyson guarantees that the filter used within the Large+Quiet Formaldehyde will final you as much as 5 years.
A tiny onboard show can cycle by way of the metrics of the totally different pollution it’s filtering and exhibits you what the degrees are in your house. These metrics may also be considered on the MyDyson app in the event you want to join your machine to your cellphone – which is advisable as that may even push out computerized firmware updates to the machine.
That’s a whole lot of options that may price you some huge cash – it’s Dyson’s most costly domestic-use air purifier to this point. If in case you have the finances for it – and, extra importantly, the house for it in a nook someplace – it may properly be price your whereas in the event you’re involved about your well being, particularly throughout wildfire season that’s turning into extra widespread with every passing yr.

Dyson Air purifier Large+Quiet Formaldehyde evaluation: Design
- Appears like a big bowl atop a cylinder
- Wants distant management to function
- Designed to be left within the nook of a giant room
After I first laid eyes on the Dyson Air purifier Large+Quiet Formaldehyde at its Sydney unveiling, I actually wasn’t impressed by its appears to be like. ‘Large’ and ‘cumbersome’ have been the phrases that occurred to me. Then the Dyson engineer moved the machine… gently, with one finger. Sure, it’s huge – however solely in comparison with Dyson’s different residence purifiers and bladeless followers – and appears just a little clunky, however it’s not as heavy because it seems. Even then, it is a good factor there are hidden wheels that transfer very easily over arduous flooring (wooden and tile). They don’t transfer as properly over carpet, although, and that’s when the Large+Quiet actually feels cumbersome.
It appears to be like in contrast to another Dyson air purifier that has preceded it – it’s principally a big bowl that sits atop a perforated metallic cylinder, every of which is packed individually within the field for delivery. You merely regulate the bowl over the cylinder until it clicks into place. It appears to be like heavy, however it’s not and might simply be lifted.
The rim of the bowl is giant, enclosing a smaller dome inside, in the midst of which is a sq. show that exhibits the metrics of the totally different pollution it’s filtering. You’ll be able to cycle by way of them by utilizing the knowledge button (denoted by a lowercase i) on the distant management. Beneath the show is a small energy button – it’s black on black and barely seen. Between the rim and the interior dome are perforations from the place the jet of fresh air is propelled right into a room.

The perforated cylinder homes the filters – two within the case of the costlier blue-and-gold mannequin (SCO and Okay-Carbon filter) and the one SCO filter within the cheaper choice. When it’s essential substitute or test a filter, you possibly can rapidly unclip the bowl utilizing the toggle change on the again, then carry off the cylinder by urgent on the 2 crimson buttons situated throughout from one another on the within. A small unperforated strip on the cylinder is the place the machine’s tiny distant attaches magnetically.
As I’ve talked about, there are wheels on the bottom of the Large+Quiet, however they’ve been designed to be invisible except you flip the entire machine the wrong way up. They’re extraordinarily clean on arduous flooring, needing simply the slightest push to roll, however require some elbow grease to maneuver on a low- or medium-pile carpet. I’m guessing it’s going to be nigh on not possible to maneuver over a high-pile carpet or rug.
Whilst you’ll both love or hate the general design aesthetic of the Large+Quiet, you need to remember the fact that it has been constructed so it will probably do its factor whereas standing unintrusively in a nook someplace. Different purifiers will must be positioned within the heart of a room and the fan stored at its strongest for them to be at their best in a small house. However how many people actually plop our purifiers in the midst of a room?
Design rating: 4 / 5
Dyson Air purifier Large+Quiet Formaldehyde evaluation: Options
- Three-phase complete machine filtration
- Breeze mode
- Modified filter and the CO2 sensor is helpful to have
The highest of the Large+Quiet has been designed to harness the facility of cone aerodynamics that, Dyson says, greater than doubles the airflow passing by way of the machine compared to its different purifiers. Dyson guarantees that this machine can course of as much as 87 liters of air per second which, whereas being a tough metric to measure, is well plausible when you think about the scale of the machine and really feel the jet of air being projected at full power.
This propelled air is meant to be mimic the motion of a spring breeze – a Dyson engineer has apparently cracked the code on the best way to make this occurred. I, nonetheless, am not fairly certain I would name it a ‘breeze’, however I discovered the air circulation very nice.
This air motion is what Dyson is looking the Large+Quiet’s Breeze Mode and there are 10 fan ranges to select from. The air could be projected in three totally different angles – 0º or parallel to the ground, 25º and 50º. I discovered that having it set at 0º was excellent for utilizing within the bed room at evening, whereas the opposite two swimsuit bigger areas like residing rooms. Throughout my testing interval, it hit 37ºC / 98ºF on just a few days in springtime in Sydney, and I didn’t want to modify on my air con because the Breeze mode was greater than sufficient to maintain me comfy in each a smaller bed room at evening, in addition to in a bigger front room house with the fan going on the highest setting.
The Large+Quiet’s primary perform, nonetheless, is air purification. Filtration right here is identical three-step system we’ve seen from Dyson’s finest air purifiers, however with important enhancements. It adheres to the HEPA H-13 customary, which implies 99.95% of particles as small as 0.1 microns can be captured, and it’s absolutely sealed so none of them can escape again into the air.
The HEPA filter, based on Dyson, is made up of 21 meters of borosilicate microfibers pleated 459 occasions to make it match throughout the cylindrical base, whereas additionally giving it loads of floor space to seize pollution and final just a few years. It makes use of selective catalytic oxidization (SCO) to interrupt down the sure pollution, notably formaldehyde, and guarantees to seize them at a molecular degree – once more, one thing that’s not attainable to check chemically exterior of a lab, however I’m prepared to take Dyson’s phrase for it.
In accordance with Dyson, the Large+Quiet’s formaldehyde sensor is highly effective sufficient to detect molecules which are “500 occasions smaller than 0.1 micron”. The filter then breaks it down into CO2 and water, which then will get let loose into the room as a part of the stream of cleaned air. It’s essential to notice that the CO2 from formaldehyde breakdown is so negligible that it gained’t be a problem in any respect.
When you go for the costlier Large+Quiet mannequin, you’ll get an extra Okay-Karbon filter inside that makes use of a layer of carbon to seize odors, some natural compounds in addition to as much as thrice extra NO2 from automobile fumes (helpful in the event you stay on or close to a primary thoroughfare) than the usual SCO filter.
Whilst you get full management of the Large+Quiet by way of its little distant management, you may as well management it by way of the MyDyson app. A digital distant management is displayed on the app and all the pieces you are able to do with the bodily distant, you are able to do on the app. You can even get graphical representations of what the machine is filtering. Nevertheless, you possibly can solely get a per-day look. I want Dyson would create a approach to see a weekly or month-to-month report back to get a broader overview of its efficiency.

Dyson Air purifier Large+Quiet Formaldehyde evaluation: Efficiency
- 10 fan settings
- Auto mode is superb
- Quieter than Dyson’s different purifiers
You want some specialised areas and gear to correctly take a look at a air purifier, however I used it in my own residence for a few months earlier than coming to the conclusion that the Dyson Air purifier Large+Quiet Formaldehyde does all the pieces it guarantees.
Picture 1 of 2
Whilst you can select a fan setting between 1 and 10, there’s an Auto mode right here that may be your default setting when it’s not too sizzling. In Auto, the Large+Quiet carries on filtering if it must, however will energy right down to Breeze mode degree 1 if air flow isn’t wanted. The second it detects an excessive amount of CO2 construct up or extra family pollution when you’re cooking, the facility of the fan routinely will increase. If there’s nothing for it to do, it’ll idle however not change off. Nevertheless, the automated enhance of Breeze mode setting occurred solely as soon as throughout my testing interval and I’ve since not been in a position to replicate this state of affairs… which might be for the perfect because the CO2 was within the crimson that point.
The place different purifiers don’t essentially decide up particles within the air except they’re actually shut by, the Large+Quiet is able to detecting pollution from a few meters away. For instance, it was in a position to decide up that there have been extra VOCs within the air after I was sitting two meters away utilizing some nail polish remover. I normally have the display displaying CO2 (which can be its default), however the show modified to the VOC display routinely to point the rise and that it was actively filtering sure particles. I even discovered that the scent of the remover didn’t linger so long as it normally does when no air purifier or fan is on.
With the Large+Quiet, I discovered a whole lot of meals odors have a tendency to remain indoors for a protracted whereas except there’s good cross-ventilation – these additionally disappeared faster than earlier than I began utilizing the Dyson.
What I actually like is how quiet it’s. Contemplating I’ve to shout to be heard over the Dyson Pure Scorching+Cool when it’s at full energy, I absolutely anticipated to do the identical once more. Quite the opposite, the hum of the Large+Quiet, even at full bore, disappears into the background as white noise.
I don’t have a sound meter to make correct measurements, however by utilizing a smartphone app to measure the decibels, I received 60dB at degree 10. That is with the cellphone’s mic held slightly below the principle jet of air and standing lower than a foot away from the machine. As compared, the Pure Scorching+Cool, which is half the peak and a fraction of the diameter of the Large+Quiet, clocked up 62.9dB. The smaller machine’s sound can be greater pitched compared to the large one, making it harsher.
Picture 1 of 2
Dyson says it’s been in a position to decrease the noise ranges within the Large+Quiet by redesigning the motor for its purifiers. Sharp edges have been diminished and tough surfaces smoothened out to cut back air turbulence contained in the machine, thus reducing noise ranges.
Efficiency rating: 4.5 / 5

How I examined the Dyson Air purifier Large+Quiet Formaldehyde
- Used on daily basis for about two months
- Left it working constantly for 3 days on Auto mode
- Uncovered it to varied merchandise, like deodorants and nail polish
I used the Dyson Air purifier Large+Quiet Formaldehyde for about 8 weeks virtually each single day. Throughout that interval, I examined it in several rooms, together with a bed room, the lounge, open-plan eating and kitchen, plus a house workplace nook.
I examined all three Breeze modes and likewise left it in Auto mode to see how it will carry out. Throughout this time, I monitored how properly it detected aerosols like deodorants, in addition to the way it dealt with sturdy odors from perfumes and meals. I additionally had it working whereas I used to be cooking to see if the metrics modified.
I closed doorways and home windows to see how the CO2 sensor would carry out and to see if the fan would routinely energy as much as ventilate the room.
I used an iOS app to measure the noise ranges emitted when it was at full energy (degree 10) and used the identical app to see how loud the Dyson Pure Scorching+Cool can get when working at full bore as a comparability. I additionally in contrast the sound degree to the Breville The AirRounder Plus Join.
