Questions about Xiaomi Smart Air Purifier 4 Pro

Contrary to the positively expressed opinion of others, I find the noise that the part makes in night mode and level 1 really annoying, i.e. I hear the even clearly visible imbalance of the apparently only cheap plastic fan wheel - which possibly bends differently depending on temperature and humidity, which steel would not do so much and of course would also be more durable.ergo, it doesn't make a continuous sound, but a constant up and down--taken exactly, probably back and forth, Doppler effect and blaaa--with every rotation, is this the same with you--I'm only talking about level 1 and night mode, just to make it clear again, since somehow you always get answers to everything else here than you actually asked--? It's "quiet" in itself, but it's not a constant, unobtrusive, bearable sound, but rather an annoying "up and down" sound. Do you also notice this with your device, or do I have a model that I should possibly return? 0.o If I look at the edge of the fan wheel from above, I can even see how the thing is wobbling -- of course less than a millimetre, but still--, so I think that with today's industrialisation, you shouldn't be able to get fans that aren't perfectly round and unbalanced.So I just wanted to ask you quickly, do you also see this with your devices, how the edge always moves in and out a bit to match the annoying sound it makes at the slightest steps? Do you have to accept this on a "Pro" model nowadays? 0.o It doesn't do me --and the pollution-- any good to go through the whole return procedure and then get back a device that is exactly the same - or, as is so often the case, even shittier, if they were all like that... @Galaxus & @Digitec: For such cases it would be useful if you could post audio or video files here, so that others could compare it with their device, or that you can hear samples from others before you even buy a device! ;)

Can this device also be used without wifi? It is intended for use in a bomb shelter where there is no reception.

does the air purifier emit ozone?

Does it also cool the air like Dyson's? Or does it only circulate it (room climate remains the same)?

Hello, Are replacement filters available from Digitec, and if so, could you give the reference/price? Thank you

Good evening, I read the article about the air purifier test (Xiaomi Smart Air, price Fr.136.-) in the health tip and wanted to order the test winner from you but couldn't find it at this price, why? Kind regards, Robert Spiess

Can the device also be used with fragrance?

Does it have air humidifier function?

Has anyone had any experience of how this device performs against pollen?

@Galaxus / @Digitec: This device has unfortunately a damn disadvantage compared to the much too expensive Dyson's, namely that it is only a filter, and not at least a fan and filter --ideally also a dehumidifier would have been great-- in one, but in the search for solutions to the problem, where I would have expected in the 3D printer scene.I found this elegant finished product, which would make the Mi Air Purifier 4 Pro a bit more useful, so can you by chance stock something like that? TLDR version: https://www.youtube.com/watch?v=BxkNOkw076E Version where also the downsides are pointed out, namely that it won't blow like a Dyson even on level 3 of the MI, but it's better than nothing ;) https://www.youtube.com/watch?v=hIT3opq5lKg Many thanks in advance.

If I order today, i.e. now, when will the unit be available? Thank you for a prompt reply :-)

Does the device also help to filter dust from the air? Do I have to dust noticeably less?

Does this product also work with Apple Home?

How often does the filter need to be changed?

Can the thing also be operated and used manually or do you really need a smartphone and app for that?

Can someone tell me why different prices and delivery availability are displayed on the PC and on the mobile phone 🤬

Where can we get replacement filters, that are in stock for a fair price? I can not even find any.

Without specifically wanting to throw a Chinanoia into the room, especially since I don't trust Americans any further than I could throw them, but has anyone with electronic skills ever checked the part for microphones (or motion sensors misused for this purpose, as in the GeStaPo phones)?<--Cool no, a malicious CrApp usually doesn't need any authorisation to use them and nothing is displayed when they are tapped...No "Alu Hut fällig?", there are PoC's of them ;P) or even cameras? 0.o Would such an inspection already void the warranty? The answer that there is no danger if you don't give it the wifi passwords is no guarantee of security in my eyes, because it could have open wifi networks in the vicinity via which it could nevertheless exfiltrate all the data it has obtained from you, if it doesn't just filter the air! ;P Really sad that because of such degenerate yuppies with the head in the --online-- cloud, where all these CrApp and therefore Wlan gimmick shit is so cool, you can't even buy a damn air filter anymore without having to ask yourself such questions... and of course having to rip apart all the devices first to scan them for barely visible or understandable potentially malicious technologies... So has any trustworthy person from the hacker community been through this with the part?

Why is it actually not possible to link or offer the associated accessories, in this case the filters. Additional sales are great! Instead, one clicks one's fingers to the bone and spouts indecent words. Please improve.

Can you adjust the humidity?
