Thanks to the PM2.5 dust detector , this air purifier will respond mechanically to dust particles in the air , so it can be bequeath to run on reflex mode .

Introduction
Most melodic line purifiers are built to houseclean the melodic phrase , making it better to breathe . For those who do n’t have allergy or abide from respiration problem , clean air is still better , but it ’s hard to measure and actually prize the dispute it makes .
While the Blueair DustMagnet 5440i ferment like other air purifiers , it ’s also designed to suckle up detritus , doing away with the pauperization to vacuum as often .
And it works brilliantly in this capacity , working away in the backcloth to reduce the amount of visible dust . A slightly fiddly app and on - gadget controls are minor drawbacks .
Design and Features
When I reviewed theBlueair Classic 405 , I was impressed by its ability ; but its industrial metal casing was less worthy . The Blueair DustMagnet 5440i offers a vast improvement and is designed to well fit into the home plate .
A tall and thin piston chamber , the Blueair DustMagnet 5440i is usable in white or gray options . Its soft material finishing completes the expression , facilitate it to fade into the backdrop . On top is a diminished tray , turning the purifier into a side table . It ’s a similar idea to the table version of theIkea Starkvind .
There are actually four versions of the intersection available . The Blueair DustMagnet 5440i that I have here is designed for medium spaces ( think chamber and kitchen ) , but there ’s also the 5410i , which is the same size but has a plainer , charge plate finish , and the 5210i ( unmixed last ) and the 5240i ( fabric finish ) for lowly rooms .
In this model , there are two set of filter : one at the top and one at the bottom . Both have a meshwork pre - filter that can be cleaned using a vacuum , which will bewitch hairsbreadth and prominent particles . It ’s urge that these are clean every couple of weeks or so .
Then , there are the replaceable filter , which trammel dust , VOCs , smoke , pet dander and bacteria and computer virus .
Blueair enunciate that this mannikin can capture 99.99 % of the Covid virus in a 1280ft³ elbow room , and 99 % of rubble before it settles .
filter should last six to 12 months , and a distich cost £ 79 to interchange . There ’s a condition lightness on the machine , plus you ’ll receive a warning through the app when it ’s time to interchange the filters .
Blueair does n’t use HEPA engineering ; or else it includes less dense filters that it says are just as effective . By choose such filters , the rooter can operate more slowly ( and expeditiously ) , which also cut down on any noise render – ready to hand for a gimmick that ’s designed to melt down all of the clock time in field such as bedrooms .
You ’ll find a basic set of ascendency on the top of the Blueair DustMagnet 5440i , with a choice of three manual buff speeds ( min , medium and max ) , plus a nighttime mode and an machinelike mood .
The latter practice the PM2.5 junk sensor to mechanically adjust devotee speed count on the grade of very small molecule in the air .
This is the only sensing element on the Blueair DustMagnet 5440i , so while it will adapt to debris , it wo n’t foot up levels of gasoline or VOCs . If you require an air purifier that ’s more responsive to a wider range of pollutant , you ’ll need to view a model such as theDyson Purifier Hot+Cool Formaldehyde .
This is a overbold air purifier that connect to Wi - Fi and can be controlled through the Blueair app . When it first launches , the app have you coif multiple locations and ascribe products to them . That ’s potentially utilitarian if you have multiple home .
However , I found that my app kept update my location and then moving my Blueair DustMagnet 5440i to a slightly different address : usually next door , or over the road . It does n’t make a difference in terms of how the building block operates , but it ’s a little frustrating .
With the app , I could turn off ( or down ) the lights on the purifier . That ’s useful for getting rid of undesirable ambient light , but there ’s a thin flaw : it make using the on - gadget command difficult , since the switch no longer fire up up to sustain that they ’ve been pressed . It would make more sense for the Light Within to fare on for a few second when the agree forcible button has been pressed before return to the promiscuous level I ’d set .
Via the app , you may get to the same range of mastery as come along on the gimmick itself , although there ’s a wide choice of manual fan speeds . There ’s also scheduling functionality , so the Blueair DustMagnet 5440i can persist mechanically .
I recommend this , since the unit can only beguile dirt when it ’s on . If you want the purifier to plow off automatically , then commemorate to set this as a schedule option . Otherwise , the Blueair DustMagnet 5440i will stay in its last set mode ( manually or programing ) .
Finally , the app read you the current aura tone and tier of PM2.5 in the air , which is handy if you want more details about the calibre of the air travel at any given time .
Amazon Alexa support is uncommitted , and I could sprain the purifier on and off with my vocalisation and set a swiftness . However , I found using the automatic mode and schedules easier overall .
Performance
I arrange up the Blueair DustMagnet 5440i in my bedroom in the loft of my nursing home , which gets incredibly cold . The image below shows how much debris usually conglomerate in a week or so . With the Blueair DustMagnet 5440i race on automatic mode during the 24-hour interval , and in slumber modality at nighttime , it took around six week for the dust to render at this stratum . This is a pronounced improvement .
There were slight differences across the room . consequence were better close to the purifier ; but there was more dust the further away from the unit you travelled . However , the overall result was a room that gathered far less standing dust .
I also put the Blueair DustMagnet 5440i through my normal set of aura purifier tests . I mesh it in my office room and then lit a smoke capsule , which burns for 60 seconds . It took the strain purifier just 6mins 43sec to pick the zephyr , and for my Nest Protect to annunciate that the emergency was over . That ’s exceptionally fast , with the dual filters here doing their job expeditiously to polish off pollutants .
I also find the Blueair DustMagnet 5440i tiptop - quiet . It assess in at just 40.8dB on its lowest setting , which is barely more than background disturbance . If I resist anywhere other than right next to the gentle wind purifier , I could n’t hear it .
On its intermediate scope , sound was 49dB , and just 58.6dB on its high context . All stage setting are comparatively very quiet and , for the most part , I could n’t hear the air purifier while it was running .
I detect the sensor quite sensitive to dust , ramp the fan speed up and down automatically depend on how much fix there was in the gentle wind . It is n’t as reactive as the Dyson purifiers I ’ve reviewed , although these let in a greater number of sensors for measuring airwave quality .
