  • How often do you replace your filter, OZB?

    • I just took it out and gave it a good clean haha .. you can also clean water purifier filters and reuse them. I have a spare in the cupboard for in a few years 😂

      • Make sure you dry it out well, also I think I read that washing them out won't clean them out indefinitely as the fine particles fill up the filter? I dunno..

        I pull mine out and wipe off the dust every now and then.

        Xiao Mi reccomend 3 months per filter, I just double it to 6 months as a reasonable life.

        I just realised I paid $70 delivered for ONE last time, so just ordered two to stock up, thanks OP!

      • Vacuuming the outside doesnt do much apart from making it appear cleaner. The inside of the filter are still full of the crap that is removed from the air.

      • The filters stop being effective for a number of reasons. A part of the hepa filter medium traps particulates as they pass across it. As more particulates are trapped, less of the medium is available to perform that function. Other parts of the filter break off in use, exposing larger gaps for pm2.5 particulates to go through. You can keep the same filter medium in use forever but it's ability to actually protect you from pm2.5 particulates diminishes. The only way to confirm if it's working is to use an air quality sensor to test effectiveness.

  • whats the difference between anti-formaldehyde and the rest?

  • Thanks, got one.

    Does anyone know if you can reset the life of a filter? I have a Pro and it''s already lost 10% but it looks brand new (I've also wrapped it in a filter).

    • if you have a 3h with the LCD screen the fix is to use duct tape or have it face the wall like a naughty child

    • No, it's linked to the RFID chip on the filter. You can cover the chip with aluminium foil and sticky tape and it won't be able to read it (that's what I do to extend the life past 3 months once I've cleaned it) but it will also stop counting down at all - so you'd need to keep your own track as to how long it's been in use.

  • Which one is better, this or the HEPA filter?

    • If you are worried about tiny particles a true HEPA filter should be better, how much better I don't know.

    • The HEPA is best for PM2.5 particles. Overall, I'd get the HEPA if the prices were the same.

  • Thanks! It is a good price.

  • Just opened a new one of these on the weekend, the old one had been running at 0% for a couple of months.
    Good timing to stock up for the next time. Thanks!

  • Got two. Thanks very much for the post OP.
    I love this community. You guys are awesome.

  • Thanks, only time it's worth getting it with free shipping!

  • Thanks getting two spare. Cheers

  • Thanks OP.. stocked up!

  • Thanks got one. Wonder if they really only last 6 months or if its just to get you to buy more.. considering air quality is so good in Australia I think it should last a lot longer. Mine has been on 0% for a few months but I will keep using it for now.

  • Being anti-formaldehyde seems like a must buy if you don't like the smell of formaldehyde from cadavers. It's a +1 for me!

  • where do you put the free shipping code? I can't seem to find it

  • Thanks! Bought 2!

  • What's this?

  • Bugger! Sold out already

    Which one of these is best? I like quiet models

    • Basically depends on the size of the area you are purifying. Personally, I'd get the 3H or the Pro (I have the 3H model) for the OLED displays and the sensors. You can see a comparison of the different models here: https://www.mi-store.com.au/which-xiaomi-air-purifier-is-bes...

      • The pro does not have hepa filter.

        And 32db seems loud for sleep mode…

        • The pro doesnt come with the HEPA filter but the HEPA filters do fit it - just put one in…

          32dBA is really very quiet, I personally use mine at night on Level 1 because I like the white noise.

          If you want something quiet - don't use anything at all. Perfect quietness.

          • @OrionAU: Comparison chart says the pro does not have a true hepa filter like the other models.

            • @BongoOB: As I said - the Pro model doesnt COME with the HEPA filter it comes with a different filter - but the HEPA filters will fit. So you can take out the filter that it comes with and put in a HEPA filter to replace it.

  • wth formaldehyde…Do people have chemistry labs at home? o.O

    • You mean, you do not?

      New furnitures/floorings can release formaldehyde

      • Yes, common treatment for wood in most countries though I'm not sure what the regulations are with that here. The nice smell of new paint is also something that may affect some people (and possibly affect your health), and this would fall under that category (VOCs).

  • Err what the hell are people doing with these? Am I missing a joke?

    • ??? It's a filter for Xiaomi air purifier.. made a big improvement to air quality in my bedroom and no longer wake up with allergies.

      • I was referring to its apparent anti-formaldehyde properties.

        • Must be an issue in China with formaldehyde - its literally in the air in industrial areas I’m guessing.

        • In China and SEA they use extremely high emission resins in the construction of engineered wood (MDF, PB, Ply). If you buy Australian, European or American (Ikea etc) branded furniture or wood they are all extremely low emissions, typically around that of natural wood.

          I use an air filter as my partner suffers from hay fever and the filters help remove dust and pollen etc. In Australia we simply don't have crap wood, crap houses and crap pollution for chemical filtering to be a useful feature for us.
