Key Features
Introduction
Dyson for certain does n’t hatful about with its product names : it ’s clear that the Dyson Purifier Big+Quiet Formaldehyde is a huge atmosphere purifier , build to make clean the largest of rooms .
With a huge range of sensing element , a long - lasting filter and exceptionally quiet execution , if you ’ve fetch outer space for this purifier , you ’ll appreciate it . The high price and enceinte size does intend it ’s not one for the masses .
Design and features
Remember theDyson Pure Cool Medesktop fan ? Well , the Dyson Purifier Big+Quiet Formaldehyde take care like a bigger version of this . And , by bigger , I do mean BIGGER – this is a demon of an air purifier .
Measuring 830 x 434 x 415 mm and weighing 11.9 kg , this air purifier look like a Star Wars Droid , and needs a average amount of space to place it . It is bestride on casters , so it ’s relatively easy to slide the purifier around , but you ’ll still only want to put this in a fairly large room .
Dyson says that the Dyson Purifier Big+Quiet Formaldehyde can project clean air 10 m and is worthy for rooms up to 100 m² , which will cover immense rooms and even entire open - design layouts .
There are two versions of this intersection useable , with slightly different lineament . I have the more expensive Dyson Purifier Big+Quiet Formaldehyde , which is finished in Prussian Blue , and has a wider chain of features .
There ’s also the Dyson HEPA Big+Quiet Formaldehyde , which is cheaper , finished in white , does n’t work with the MyDyson app , does n’t have a distant ascendance and does n’t have an adjustable airflow angle .
Unlike premature Dyson purifiers that I ’ve reviewed , such as theDyson Purifier Hot+Cool Formaldehyde , the Dyson Purifier Big+Quiet Formaldehyde is not specifically a cooling buff as well . It shoots out a burst of air , but it ’s not as easy to direct it , nor is the air flow as targeted . bribe this product because you want a purifier , not a multi - function gimmick .
plant up is easy , as the Dyson Purifier Big+Quiet Formaldehyde comes with pre - installed filter , so the twist just needs pulling out of the boxwood and plugging in to get started . filter can last for up to five class , at which breaker point it ’s £ 60 for a new HEPA filter and £ 60 for an activated carbon paper filter .
Replacing the filter is wanton : pull off the head , imperativeness in the clips to slide the outside sheet up , and then the HEPA filter can be pulled up and out , and the carbon filter unwrapped from the inside . It ’s then a matter of doing the job in contrary to reassemble the purifier .
Neatly , the external shroud can be rotated , so the charismatic remote control holder can be moved to the place that you want it in .
The HEPA filter is designed to capture small mote ( 99.95 % of ultrafine particle down to 0.1 microns in size of it ) , and the C filter is plan to catch gases ( benzene , NO2 and more ) . There ’s also a selective catalytic oxidation filter for formaldehyde , which turns the harmful substance into CO2 and oxygen and never require replacing .
As with Dyson ’s purify fans , the remote control can be used for full dominance over the fan , including manually changing the buff speed , and adjusting the direction of the purifier ’s output .
As with the Pure Cool Me , the Dyson Purifier Big+Quiet Formaldehyde takes vantage of the Coanda consequence , where air comply the path of a curved aerofoil .
By default , the purifier uses Breeze modality , which is designed to simulate a substantial Spring zephyr , but the top and bottom jets can be adjusted , alter the angle of the melodic line . It ’s a useful trick to have .
I establish that adjusting the airflow meant that I could have the purifier on without being pose in a watercourse of frigid air travel .
While the buff swiftness can be adjusted manually , it makes more sense to leave the Dyson Purifier Big+Quiet Formaldehyde in Auto mode . Thanks to the wide range of sensors onboard , the purifier can respond to lots of pollutant , changing buff velocity on need .
Sensors can notice the amount of particulate matter , which are small particles in the air . There are detector for PM2.5 ( very little particles ) and PM10 ( minor atom ) . A VOC sensor detects harmful gases , and there are also sensors for NO2 ( often cause by car ) and formaldehyde . There are also temperature and humidity sensors for completeness , plus an overall zephyr character valuation that take aim into account Reading from all sensors .
Such a compass of sensors means that the Dyson Purifier Big+Quiet Formaldehyde is much more responsive to air quality issues than purifiers that only detect particulate matter matter . I come up that the fan would spin up after I opened the kitchen threshold , detecting pollutants from outside . Spraying gloss to clean a table , the purifier detected increase particulate matter matter , and spin up its fan .
What Dyson purifier do make you notice is just how variable air tone is , and how many time you ’re expose to pollutant .
As well as using the remote , the Dyson Purifier Big+Quiet Formaldehyde can also be connected to Wi - Fi and can be control using the MyDyson app , home to all of the company ’s sassy machine , including theDyson 360 Vis Navrobot vacuum cleaner .
As well as duplicate all of the controls useable through the remote control , link up the app give vox controller via Amazon Alexa and the Google Assistant , plus historical records go back seven days show historical air quality , plus graphs of meter reading from the case-by-case sensors .
Performance
In general twenty-four hour period - to - day use , the Dyson Purifier Big+Quiet Formaldehyde is impressive . Its widely - cast sensors mean that any impurity in the melody is notice and dole out with fast , revert the air quality to the green level . imposingly , the purifier only increases rooter speed to the point where it needs to remove the current trouble , and it ’s relatively rare to have it spin up to belt along 10 .
When the purifier does hit maximum velocity , the declamatory fan and cagy design mean that it ’s still quiet : just 49.8dB from 1 m aside in my psychometric test . In oecumenical use , it ’s middling much impossible to hear this purifier running game , and it ’s not distracting in the fragile .
To see how chop-chop it can remove the air , I lit a smoke pellet , which burns for around 60 seconds . I find oneself that the Dyson Purifier Big+Quiet Formaldehyde get hold of just 6 thousand 11s to clear my spot of smoke and have the Nest Protect report that the alert was over .
The Dyson Purifier Big+Quiet Formaldehyde did stay on for a total of 15 m 50s until it report the airwave was whole green : the fan speed was slow deoxidize over this period . Overall , this is the fastest and most powerful tune purifier that I ’ve prove .

Final Thoughts
