Xiaomi Mi Air Purifier 4 Pro
consider the deal I just posted before pulling the trigger:
https://www.ozbargain.com.au/node/760706
I ordered a Phillips 1000i in the afternoon :/
which is better https://www.ebay.com.au/itm/224977869261 (MC40) or Phillips 1000i or this Xiaomi one ?
Where did you get the Phillips from and how much? Thanks
$299 from HN :/
Definitely get a Philips, Samsung or Daikin over Xiaomi.
Xiaomi performed poorly on the Choice Magazine tests.
I have several Xiaomi and several Philips and Philips is better. Wish I knew before buying the Xiaomi ones but bought them many years ago
I have several Xiaomi and several Philips and Philips is better
How'd you figure this?
I've owned at least five different brands, include one brand still made in Switzerland and a handful of DIY machines. Tested them all with particle counters. All of them work, it's a question of how much cost, noise and space you're willing to trade off against. The Swiss one is 'better' in terms of pure filtration performance, but the others are all effective 'enough'.
I ended up buying several small Xiaomi units for smaller rooms simply because they are cheap and quiet. Got the Gen1 ones which don't use RFID chips. I dislike the "Pro" versions of the Xiaomi though- they are simply too big.
Side note: Air filters are not black magic high tech whizz bang machines, they are literally just a fan with a filter in front of it. I have no idea why they are so expensive beyond people being willing to pay that much for them.
Xiaomi performed poorly on the Choice Magazine tests.
Don't spread misinformation, please — it did not "perform poorly", if that's the case then the Philips performed "poorly" as well since it got even worse scores than the Xiaomi 3H. CHOICE's air purifier tests favour bigger machines with higher CADR, so smaller machines like the Xiaomi 3H (and the smaller Philips machines) will always score lower. CHOICE has not tested the Xiaomi 4 or Pro machines.
People really need to stop quoting CHOICE test results without understanding what they mean.
Every post about air purifiers is filled with misinformation these days, sigh.
Also, simply removing the particles from the air doesn't necessarily mean air purifiers are good for you. Whenever I run my air purifier, I get an instant store throat, which lasts a day or two. I did a bit of research, and apparently some studies have found air purifiers release all kinds of unnatural chemicals into the air via their filters. Quite bizarre when you think about it.
@ForkSnorter: This is why you but a second formaldehyde air filter to filter the air from your first filter.
FYI
Not HEPA
Less clean air - HEPA filter is made of dense fiberglass to trap particles, which means that less clean air get through the filter.
More clean air - Xiaomi's High Efficiency Filter integrated melt-blown PP fibers with electrostatics technology equipped with bigger fibers space, which enables a large volume clean air to get through the filter.
Why neg ??
this is from the official site.

Not exactly.
Indeed HEPA is a quite low standard for air purifier. All filters from grade H10 to H13 are all called HEPA, though huge diffs in price and spec.
Xiaomi usually uses H11 grade paper as base layer for its filters and add some more process for better ventilation.
If u search Xiaomi filters on the same website, u can find a detailed explanation about why they r better than conventional HEPA filters.

man my air purifier pro cant be reset…its no longer a smart device now.
Try this method of resetting the filter life.
https://www.reddit.com/r/Xiaomi/comments/n8anq1/mi_air_purif…
I removed my 3H from mi home and haven't been able to reconnect it by wifi no matter what I do with my wifi settings (2.4GHz WPA2 etc etc).
I even tried resetting the EEPROM like above but to no avail.
When I did a filter change, I couldn't reset the counter using the button. but all it took to reset it was turning it off at the wall while I did the swap. When it powered up with the new filter in, it was reset.
So hard to find HEPA filters now. Kogan, who I feel troubled buying.from, and Amazon.$$.no stock anywhere else. I am very close to needing 2.
Have you tried eBay?
Seem to be a lot of listings under a simple search. Just wondering what the quality is like.
https://www.ebay.com.au/sch/i.html?_from=R40&_trksid=p233452…
I've purchased a third party filter from eBay and whilst I haven't conducted any qualitative tests I can say that:
Cheers, for your reply :)
I have the version 3. Not a fan of the filters as they have rfid tags in them and the device constantly tells you to replace them with a new one. It doesnt go away until a new filter is installed.
Whereas on my breville purifier i can clean the filter out for longevity without that constant reminder from the unit and app.
Other than that, the device is great
!! ffs rfid tags
See my comment above. You can reset the filter life back to 100%
You can use aftermarket filter for series 2 and 3, they shared same filter. I have used all aftermarket without RFID. lots of promo if you could find with pack of 2. You still need to do reset once installed
Nice price. Hasn't been at this price for some months.
Though the Standard Shipping $27.95 is kinda high.
Whats the point of purifying your air at home, if you are going to get all that bad stuff stepping out into the big smoke which adds up to far more crap going to your lungs ?
Better sleep (pollen/allergies), odours (cooking etc), cuts down on dust
You talk like someone who's made that choice.
Actually, you talk like someone who's had that choice made for them.
Have you noticed the pattern that every time you say "what's the point to X, X makes no sense" and then after X is explained to you:
What do you think is the more likely explanation for why this happens every time: you're wrong or we're all wrong?
@CrowReally: Plants and. pollens have smells and are present outside. If you live in the big city, then you have pollution.
Now tell me which of my above two statements isnt true ?
@CowFrogHorse: I don't know where you got the idea I could interpret your broken sentences, because I really can't.
You've communicated weird ideas, badly. A bit of a constant theme, really.
I'm not going to call you useless and stupid because of that, but I'm also not going to waste my energy doing your thinking for you, either.
Now have a really good think about my question: are you wrong or is everyone else wrong?
@CrowReally: Oh yes the talk of the fraud.
You cant provide any evidence for anything i have said instead you invent lies.
QUOTE me, dont INVENT lies, QUOTE ME.
@CowFrogHorse: I don't need to invent lies. By asking you "why does everyone downvote you? why does everything think what you're saying is bad/useless?" i'm just asking you what you think is the answer to a question.
A question that you're uncomfortable with, because the answer is "everyone thinks CowFrogHorse is shit".
I don't see any good in you at all. Find someone else to try to appeal to.
@CrowReally: crow: I don't need to invent lies.
cow: you do invent lies…
when you goto court you have to provide evidence. The evidence of what i have said is here in comments. YOU NEVER PROVIDE LINKS OR COPY PASTE OF MY COMMENTS.
You rewrite my words to mean something else. That is not evidence, that is fabrication.

crow: By asking you "why does everyone downvote you? why does everything think what you're saying is bad/useless?" i'm just asking you what you think is the answer to a question.
cow: Because they are dumb just like you cant read or write half the time.
Feel free to pick any item they down vote me,.. QUOTE what i said and i am happy to debate you. All that i ask is when you have comment to make about a statement of mine, you first QUOTE me, and then write your peice. One question at a time.
I know you never do (without a carer)
I'd love to see you take some responsibility for your own life.
You won't, but that does not mean I didn't want to see it.
You're right. You should get one for outside too
This or Daikin?
Weigh the costs of replacement filters
Check out Choice Magazine reviews and test results. In short, Philips and Samsung beat Xiaomi. There's also some other dedicated air purifier brands that beat Xiaomi. Xiaomi performs overall pretty average kind of defeating the purpose of having an air purifier.
Can you send the link? I can't find any review unless i join and subscribe.
I've done a boatload of testing at home over the past decade on this stuff. Had at least ten purifiers and two (simple) particle counter testers.
Brand doesn't matter. What matters is the amount of airflow you get through the HEPA filter, and that depends on the size and speed of the fan. Bigger fan = bigger box. Faster fan = noisier box. So saying "Philips" or "Samsung" is better is meaningless without context- how big were they, how noisy were they.
I use small Xiaomis for bedrooms. I just adjust the speed according to the room size. They are pretty quiet machines, that work fine.
I also have IQAir and a Sharp for the living room. The IQAir has better raw performance (it filters a lot more out) but it was also cost over a thousand and is much larger.
@rumblytangara: ^ Thank you — you know what you're talking about, a breath of fresh air (pun intended) in these threads. CHOICE tests favour bigger and more powerful machines, so it doesn't mean the smaller and lower-scoring machines perform poorly.
To those wondering: buy the machine that suits your particular needs, within your budget — if you stick to the established brands (and yes, that includes Xiaomi and IKEA) you're unlikely to go wrong.
@rumblytangara: Main thing I was looking for was VOC filtration. The Philips filter has a lot better VOC filtration capacity and you can tell by looking at the filter size and feeling the physical weight of the filter.
But yes bigger is better but with the Xiaomi purifiers I THINK the bigger and higher CADR models use the exact same filter meaning they're just forcing more air through with a more powerful fan. The carbon cannot therefore absorb enough in alignment with the airflow.
I would strongly recommend buying the next size up for your room. Means you can run them at lower speeds and therefore lower noise levels with the same filtration capacity. Sure the Xiaomi has impressive CADR but it sounds like a jet engine on full blast! Even anything moderate is pretty noisy. The Xiaomi on auto is whisper quiet but also moving shit all air and not doing any decent rate of air exchanges to actually filter anything. I run my Xiaomi on manual mode just to make sure it actually does something than give you a false sense of air purifying.
@0 0 0: I have looked at the carbon filters on a slew of purifiers, and the only one I have found convincing is the IQAir V5 unit, which is iirc three pounds of carbon and potassium permanganate. Up from that is the actual gas-specific IQAir machines but they are high specialised. The old clunky Sharp units had decent carbon filters, maybe a pound of carbon. Everything else I've seen just has token filters.
I have retrofitted large carbon filters into Xiaomi units, again to about a pound. Certainly more carbon than most off the shelf machines sold for home use. If your primary interest is VOCs, this is pretty easy to do. I found a cooking basket (eg for deep frying) that fit into the centre of the filter, glued it in place and filled it with activated carbon pellets. Extremely cheap and easy.
That said, all this is based on gut feel. VOCs are far more complex to measure than particulates, and I've never bought or made the equipment required to properly investigate this.
I've measured every purifier I've owned with particulate sensors and noise meters. If a room is in the small side and not leaky, it's surprising how effectively a small unit can work even at low speed. One distinct advantage of the cheap Xiaomi units is that they have a whole slew of steps in motor speed (off memory around 14-15?) so you can tune for airflow and noise much more finely than other units which typically have three speeds (or six for IQAir).
I eventually settled on a mixture of IQAir, old school Sharp for living areas, and Xiaomi for bedrooms. This is the combination that I was happy with enough to ship back to Australia.
I've looked at every other brand of purifier in stores (mind you, this was overseas in a place where the range was much, much bigger due to shocking air pollution) and was not convinced that there was anything more compelling. The high flow BlueAirs were interesting, and had good acoustics despite reliance on massive air volume, but the running costs were terrible, with filter replacements every six months. They are probably also hard to find here.
Oh, the big Xiaomi models use a specific filter unit. The entire thing is essentially upsized, although they might use more than one fan- I can't recall and also didn't like the crude method of just making everything bigger so never bought one.
@rumblytangara: Nice mod. I considered that but worried I'd end up blowing carbon dust around due to our being after the HEPA filter
@0 0 0: There's practically no meaningful loose dust in decent quality activated carbon pellets. You might get a tiny puff of dust in the first ten seconds the fan was turned on, which would amount to nothing. Any dust is going to be far, far larger than PM10, so there will be no health concerns.
Seriously, if VOCs are a concern, almost all home filters are a complete joke and DIY would be the only alternative I would consider. If you've got a photo of the Philips carbon filter and it's substantial, I would be interested to see it as I have looked long and hard at everything I've come across overseas.
I've certainly not checked everything, but the only three filters I have come across that seemed substantial were from IQAir, Austin Air and Sharp filters from >10 years ago. Austin Air has problems with noise and power consumption, and the VOC filter is built into the HEPA filter, so is not independently replaceable. Sharp has since gone the same route as many other manufacturers and cheapened out on the carbon filters.
Holding out for the Samsung AX50 to go on sale, does this compare?
No more filter for 3H? Didn't see it for a while…
Which is a better buy? 3H ($290) or the 4 lite ($270) ?
Truly unnecessary marketed sale in Aus? We have one of the best air quality in the world. With the exception of few instances of bush fires, I can see this thing provides any real benefit in day to day living?
Those who have dust and pollen allergies perhaps?
Does it really though?
Not me but theres been others who said so.
@xoom: The only scenario I think someone need an air purifier is if they are a hermit who always stay in the room with no window opening.
@Lancerx: Or just someone who has dust/pollen allergies as already stated. Whether you open windows or not, it's functionally impossible to stop allergens from getting into your house. Allergens spread everywhere in accumulating amounts via open windows/doors, your clothing, hair, shoes, pets etc. Very regular cleaning with a HEPA filter vacuum is the most important measure, so an air purifier is really just one additional layer in someone's 'defenses'.
I agree with this for the most part. Bushfires yeah. Anything else… not so much. Pollen allergies- well unless you keep doors and windows closed, run whole-house filtration, then a couple of pathetically underpowered purifiers scattered around the house are going to do bugger all.
Spend a couple hours outdoors, open a window, and blam- you get smacked around big time by the allergens enough to last all day. If the house isn't already full of them because it's not vacuumed religiously.
We have have pollen allergies and asthma in the family. We don't even bother to tackle this with purifiers as we have the windows open for summer and Sydney is off the charts for pollen. I brought mine with me from overseas because I already had them and had plenty of shipping space.
I honestly have no idea why people buy purifiers here- I think it's down to marketing and a reliance on placebo.
dammit i spent $399 on this :(
this is a really great deal!!
Standard Shipping $27.95
