Dyson Purifier Hot + Cool Formaldehyde: How we tested
We tested how well the Dyson Purifier Hot + Cool Formaldehyde could improve air timber in a 140 - substantial - metrical foot ( 13 square meter ) bedroom . Using an melody particle meter that detects tiny particles value 0.3 to 10 microns , we did a serial of test to assess change in air quality .
First , we ensure the baseline air lineament in the room before deform on the purifier . We then launch the purifier on motorcar mode for 30 minutes and test the particle levels again to see if there was an melioration . We did the same test using the purifier ’s highest fan setting to compare auto versus grievous bodily harm amphetamine operation .
To dispute the purifier , we burned compeer and incense cones to release more particles into the air . We measured molecule count before and after running the unit on machine modality to see how well it handled the contamination .
We also quantify dissonance point ( decibels ) on every rooter setting , including sleep modality , and we looked at how easy it was to set up , habituate and maintain the Dyson air purifier .

Dyson Purifier Hot + Cool Formaldehyde: Design
There ’s but no denying it — this purifier is magnificently design . The Dyson Purifier Hot + Cool Formaldehyde is streamlined and expensive - looking but stocky enough to be a pernicious and stylish addition to any room .
Standing 30 inches ( 76 centimeters ) tall with a base diameter of around 8 inches ( 20 cm ) , it ’s much little in height and footprint than the Dyson Purifier Cool . you may pucker it aside in a corner or have it on full show , plus it ’s portable enough to move from way to room .
This purifier feature Dyson ’s signature bladeless lover design .

Just above the penetrate matte gold root is the power switch and LCD display . The displays shares live air quality data and fan speed . While you ca n’t control the purifier ( apart from switching it on and off ) via the unit , a curving matte gold removed control is also provide , which magnetically attaches to the top of the rooter when not in use — although this does tend to fall off occasionally .
The nucleotide domiciliate the impressive filter system , with an easy - push door latch to release the cover and allow access to the filter inside . The whole thing feel seamless , visceral and impressively designed , even by Dyson ’s high standards .
Dyson Purifier Hot + Cool Formaldehyde: Performance
We tested the Dyson purifier in a sleeping accommodation with the windows and doors keep out . We began by checking how well it could improve ambient air quality . Using an air particle beat , we mensurate the atom grade before and after running the purifier for 30 second on the reflex fan setting .
We were amazingly disappointed with the resolution on the first test . At fan spirit level 4 , the Dyson purifier only achieved a 75.9 % step-down in 0.3 - micron particle and a 70 % reducing in 2.5 - micron mote . Ideally , we expect to see at least a 95 % simplification in these diminished atom , and in fact Dyson claims its atmosphere purifier can absent 99.95 % of molecule as small as 0.1 microns .
We execute the same trial using the high devotee setting ( fan level 10 ) and have only slightly good result — a 76.7 % reduction in in 0.3 - micron particles and an 85.7 % reduction in 2.5 - micron particles .
However , things look up when we moved on to our incense test . We glow incense cones for 10 arcminute in a room with the window and doors closed . Burning incense put out large particle into the aura that can pose a risk to human wellness . The Dyson purifier achieve a very impressive 93.8 % and 95.8 % reduction in 2.5 - micrometer and 10 - micrometer particles at 30 minutes .
For the match mental testing , we burned 10 matches in a row in the room , loose thousands of particles into the air . Again , the Dyson performed exceptionally well under these circumstances , eliminating 99.5 % of 0.3 - micron particles , 98.4 % of 2.5 - micrometer particles , and 100 % of 10 - micron molecule in just half an hour .
It ’s not rare to see air purifiers that struggle with improving ambient air do a great Book of Job removing particles released in the incense and peer tests . However , we ’ve tested quite a few tune purifier which seemed to sweep through our testing with much better result , many of them far below the insurance premium price of the Dyson . So overall , a interracial pocketbook when it came to our examination .
During all our testing , however , we were impressed at how quiet the Dyson was during operation . Even at its most powerful fan setting it did n’t clock in over 48 decibels , which is quieter than a normal conversation . At its quietest , it was scantily discernible at just 24 dB , around the same as a susurration .
Dyson Purifier Hot + Cool Formaldehyde: The good
We really like the Dyson purifier ’s fashionable , compact bod that tucks nicely into recess without demanding a muckle of real landed estate . The mod colour system of bloodless , bronze and gold is classy and elegant , with a elementary bladeless silhouette and gently sweeping oscillation .
Operation is also refreshingly visceral between the easy - to - achieve power button , the magnetized remote that attaches on top when not navigating configurations , and connecting through a smartphone .
Dyson Purifier Hot + Cool Formaldehyde: The bad
It ’s hard to recover much to criticise about the Dyson Hot + Cool Formaldehyde . However , its gamey price ticket — $ 849.99 at the meter of committal to writing — has to be note . This is premium dominion for gentle wind purifiers , and not many household will have deep enough pockets to separate out for such an expensive appliance . That said , the multifunctional fan for heating and chilling , plus the formaldehyde filter does intend you get an horrific mint of hit for your vaulting horse .
As many vendee have commented on the Dyson site , the fan ’s cooling power go away something to be trust . While it ’s not advertize as an airwave conditioning unit , the Hot + Cool element of the Cartesian product name does suggest some control condition around the cooling temperature , which is n’t present and could be misleading . So , if cooling your surroundings is an all important aspect for you , it might be better to swerve this purifier and bribe an air conditioner instead .
If we wanted to be tiptop - fussy , the remote control condition could rest atop the social unit more dependably with a better attraction , and 360 - degree cycle might be gracious , but really these are very pocket-size gripes .

One disgruntled owner complains it " does n’t cool . Seriously misleading .
