Introduction
Levoit ’s 400S line purifier is designed for relatively large rooms . It can exchange the air in an 83 substantial beat ( m2 ) space up to double per hour , which ought to be enough to keep the air fresh in a bombastic kitchen / diner or loose architectural plan life orbit . It ’s equipped with a three - stage filter that can remove dust , allergens and even viruses , but there ’s no ultraviolet Christ Within for extra sterilisation .
This zephyr purifier has a built - in particulate matter sensor , so it can step up the sports fan speed if the air travel lineament degenerate – for instance because you ’re grilling or fry in the kitchen . It also offer dim-witted controls , enhanced by Wi - Fi connectivity and app support , so you may configure schedules and pluck a few other preferences too .
Design and features
If you ’ve got a large room , you ’ll need a gravid air purifier . The Core 400S is certainly a step up , but it ’s not vast , arrive up only slenderly eminent than the average chair seat . Like many other air purifiers , its cylindric design combines a gravid air input and filter chamber in the base with a sports fan section on top . Levoit ’s pick of white and black plastics looks tasteful and modern , if perhaps a chip businessy .
In the center of this purifier ’s opprobrious air turnout there ’s a round dominance panel , with a choice of button and indicator . At their centre you ’ll find oneself a numeric display showing the current reading from the Airsight Plus airwave lineament sensor . This only detects PM2.5 particulates ( those with a diam of 2.5 micrometer or less ) , but it enables an machine mode , in which the Core 400S can step up its devotee speed if the air quality turn down .
There are four manual fan speeds , but also Night Mode , in which the rooter barely ticktack over and the control panel light are extinguished . you could also use the control panel to set an off timer in one - hour increments up to 12 time of day , and there ’s a ringlet role to stop others messing around with it .
This is a overbold machine , however . set up the VeSync app , apply it to connect the Core 400S to your wireless meshwork , and you ’ll have access to more features , data and options . Perhaps most significantly , VeSync lets you set schedules , so you may configure the Core 400S to fit in with the time you ’re likely to be home .
The VeSync app shows up extra selective information , including historical gentle wind cleanliness and fan speeds . you may also expend it to tweak the setting of Auto Mode , prioritize crushed dissonance , or tune up it to the size of the room the filter is in . At its lowest , the lover will switch to the scantily - on speed used in Night Mode , but unlike the more expensive Levoit Core 600S it wo n’t actually stop , even if the line quality is gross .
Before you may use this air purifier you ’ll need to transfer the plastic bag from its filter , which involves turning it upside down and take away the base of operations . Ideally you ’ll also do this every few weeks to vacuum off junk , which helps keep the filter working optimally . Levoit does n’t state a fix filter life as it depend on your dwelling and how intensively you use the purifier , but it state you may expect transposition to last around 6 - 8 months . That means you ’re potential to change filter once or double a year , and at more than £ 60 a go that could be quite an expense .
Performance
This air purifier was quick to reply to deteriorating zephyr quality , almost straight off step up the fan speeding when I placed a get off - peer a few centimetres from its sensor . It do quite strongly in our more ensure fastball run , where I placed the purifier in a small room along with a smoke shot that produces copious particulates for about 60 seconds . This test immediately sends an air purifier ’s air quality meter off the scale .
It took the Core 400S five minute to come down from its maximal 999μg / m3reading , and a further four arcminute before it returned to a restrained reading of 54 mcg per cubic meter ( μg / m3 ) . After 10 minutes it reported good strain quality , and one minute later this had become very good , with an 8μg / m3reading . This is a decent performance , but it ’s some means short of the more powerful Core 600S , which returned the zephyr quality to very near within six minutes .
I use a second tune tone meter to affirm the readings from any on - circuit card sensor , but in this test I made the misunderstanding of placing the burning shot too close to the the Core 400S. The purifier ’s powerful fan drew skunk from the pellet away from the 2d meter , so it devolve low - than - normal results .
My other tests confirmed that the Core 400S has an unusually powerful rooter . Measured 15 curium from the output signal , I read an air swiftness of 4.9 meter per secondly at full power , shake off to 1.2 m/s at the low normal fan speed . Even one metre above , I measured 2.2 m/s at full power – enough to stir up a noticeable draft in a medium - sized way .
fortuitously , this walkover is n’t play along by too much noise . From a metre aside , I recorded only 25.2dBA in Nox musical mode – barely audible . This rose to a upper limit of 42.7dBA on full power , which is just about enough that you ’d need to raise your voice slightly . If you stick to speed three ( 39dBA ) and below , you should n’t even need to do that .
This is an efficient air purifier , using just four W in night manner , rising to 6W at upper one . This creeps up a minuscule to 15W by the third speed stage setting , but even at full great power I measured just 23W , which is excellent given it ’s fairly powerful .

Should you buy it?
With a powerful fan and adequate filtration , this air purifier is well suitable to support blank space in a decent - sized home . Its detector means you could set up and draw a blank it , while the app means there are more configurations and control available if you do take them .
The Core 400S is overkill for small place or rooms . Conversely , it ’s not the most powerful air purifier around , and it misses out on ultraviolet illumination sterilisation .
Final Thoughts
If you want an atmosphere purifier you could set and blank out , the Core 400S might be a dependable choice . Its sensing element does n’t plunk up volatile constitutive compounds , but it ’s a useful addition that should ensure the purifier ’s working intemperately when the air ’s most in demand of being cleaned . With a potent lover and decent operation against dope , it ’s up to the demands of sensibly big support area , too .
I really care the VeSync app , which adds some utile features without being overly complicated . I ’m also impressed by this purifier ’s broken interference and efficient running , even at high speed background . That tell , this purifier in all probability is n’t idealistic for those with health conditions , who may benefit more from one with a disinfectant UV lamp , such as theLeitz TruSens Z-3500Hor something else from our templet to thebest air purifiers .
