    I have an older version, it goes ballistic when we're cooking. But other than that, it sits pretty idly. I think if you don't have allergies or whatever, these things solve a problem in developing countries have which is bad air quality from pollution. Australia doesn't really have that and you could probably give it a miss. That's been my expereience at least.

      These things were a godsend when Canberra was covered in smoke. Its nice peace of mind to have.

    • +12

      I've got an older version too, and I'm not even sure the auto sensor does anything - it has been sitting at the lowest speed it's entire life.

      This is in contrast to a pricey Blueair I also own, and it at least kicks it into high gear whenever I let one rip. Regardless of whether it smells or not, everyone in the room knows what went down when the fan starts up.

      • Mine would barely do anything unless there was smoke from cooking or we had the bbq going and left the door open, then it would start going nuts. That's hilarious about the Blueair!

      • +1

        I'd like one of those dyson purifier fans that also rates your farts

    • FYI, when the fan is barely spinning (typically on "auto" mode) the air purifier is not actually doing its job of cleaning the air. You'll need to run it at medium or max speed for proper effect (which makes it rather loud). You really need to force that air through the HEPA filter in order for it to capture the particles.

      And you're right, an air purifier is kind of a niche use case for most people. Right now, the typical scenario for Aussies would be:
      - deal with bushfire smoke
      - trap and reduce virus particles, including COVID (in enclosed spaces where ventilation and fresh air isn't possible)
      - reduce the effects of pollen/alergies

      Depends where you live in AU. If you live next to a freeway or high traffic road, than you’re getting a lot of PM 2.5

    • Yeah when I had a Xiaomi purifier the sensors were great for smoke but piss poor for dust. I have older Coways that work properly though.

    Any genuine filter bargains for the 3H? Mine runs below 10%.

    Does this help filter out the covid virus in a covid positive household where there are vulnerable people who are vaccinated but still covid negative? Any covid experts care to chime in? Cheers

    • +1

      Not a COVID expert, but HEPA filters will help reduce the concentration of infective particles in the air within confined spaces.

    • +1

      Not sure about COVID, but have a friend who has asthma and is sensitive to dust and she swears by it - I bought one just to see what the air quality is like in my household - so far pretty good - only jumps up a bit when the vacuum cleaner is going

    • +1

      Yes, air purifiers that use HEPA filters do help in reducing the amount of virus particles, this is proven technology.

      As with everything though, it's not 100% foolproof. Ventilation and plenty of fresh air is still the best approach, an air purifier is basically a stopgap measure where this is not possible.

  • I have the 3H (or 3C), I don't know if it does anything, just leave it in the corner running, haven't noticed any improvements to my allergies or anything. Was probably a waste of money.

  • +2

    I miss the 2H/2S models being around the $120 mark, with various (Kogan) discounts on top.

  • +1

    10% (if you are with ANZ card) cashback from cashrewards to buy it from Amazon.

  • +2

    I have the 2h.
    Goes nuts if you do a fry up. Was great during bushfire smoke last 18 months. Pretty good value for the money…this one maybe not so much on the value side but they are a decent product.

  • If you are really serious about purifying air, recommend winix zero 5 stage. Had both. The amount of throughput is beyond comparison. The sensor on the Xiaomi is great, but I would need to run probably 3 Xiaomi to do the job of one Winix zero plus.

    There are reasons why Xiaomi is cheaper than other brands. It makes you feel you got a bargain on paper but the real world performance leaves a lot to be desired…

    • +1

      The winix will produce Ozone, the Xiaomi won't. Dunno if it would be enough Ozone to be dangerous, but I would prefer a purifier that doesn't product Ozone.

      • +2

        The Xiaomi also has a negative ion generator, as they don't specifically mention it doesn't produce ozone, I'm going to assume it does.

        • +1

          I didn't realize it had that. I would skip it for that reason, but I know for others this would be a selling point.

          • +1

            @Aureus: I was actually reading a few reviews on the Purifier 4 /Pro before this deal was posted, and apparently the ion generator is turned off by default, and needs to be turned on in the app.

        • +1

          Why would it produce ozone? The Xiaomi series are air purifiers that use a HEPA filter to capture particles.

          • +1

            @deadpoet: The Purifier 4 /Pro have negative ion generators now, they generally produce ozone as a consequence of how they work.

            • @TheContact: My apologies, you're right, I didn't know the 4 Pro has this new feature. I think it's mostly pointless extras to justify a higher selling price though, all people really need is a basic air purifier that uses a HEPA filter, and the earlier 2 and 3 series serve this purpose excellently.

    • You're kidding right? The sensor on the Xiaomi is its main deficiency. It can detect smoke but no dust, it's designed for polluted cities.. Unless something's changed in the last model or two.

  • Aka the fart detector

    I have four of these at home as well a a wife and three kids, they all do fk all and just eat my money

    I know what you mean, my family’s the same.

    Considering the Xiaomi Mi Air Purifier 3H were going for less than $200 during last month's eBay sale, how much of an upgrade would the 4 Pro be at the $340 price point?

    • +1

      Personally I think the 4 Pro is a load of rubbish to justify a higher selling price. Yes, the CADR (clean air delivery rate) is higher because this is a bigger and more powerful unit, but the other extra features like "negative air ionization" and the new "high efficiency filter" are mostly useless marketing BS.

      The Xiaomi 3H at ~$200 or less would be a good choice for most people who need an air purifier, when it goes on sale. When it comes to air purifiers, it's best to keep it simple.

  • This Mi Purifier 4 Pro version doesn't appear to have a HEPA filter?

  • i am sure with newer model, the only real "upgrade" they have is the fact it is harder to spoof the NFC sensors to bypass the filter check.

  • i need this thanks OP
