    Nice. Mine's been sending me notifications for the last four weeks that it needs replacing.

    Been pretty happy with how long it's lasted, just short of 12 months BUT 3 months of that was during bushfire season where we had a massive bushfire burning most of that time only 20km (and at one point, less than 10km) from us. Some days you could only see a few meters down the road.

      I haven't even had mine for 6 months and it's doing the same. One bedroom apartment, don't cook every night, leave it on auto. Wondering if my 3H is faulty, should last longer than this, right?

      • +1 vote

        It's designed for the very polluted China and also to get you to spend more money. The filter is fine.

      • +2 votes

        Yeah mine is the same after 6 months. I leave it on auto as well and rarely here it comes on so I'm assuming this alert is time based and not actually how much usage the purifier has had.

        I think it might depend on your environment (i.e. things that would trigger the fan), not necessarily air quality. I think it's best to not have them right up against a wall, as anytime some dust gets even slightly stirred up the fan will kick in.

        •  

          Yeah, have given it space away from the wall. Fan only kicks in when I cook on the stove, which isn't very often. Looks like it's based on time. Apparently can stick some metal between the bottom of the filter and the base to disable the NFC and stop getting the warning. Might give this a crack.

        It looks like it automatically goes down around 1% per day.

        No matter what level I leave it on.

      •  

        Depends on the air quality and the environment the unit lives in.

        I have 2 filters, one upstairs and one downstairs. The unit upstairs had to have its filter replaced after 9 months, while the one downstairs is still going strong for over a year now. And sure enough, I opened the upstairs unit and checked the filter, it was completely caked in dust and it did need replacing. The unit sensors are more accurate than you think about how soon a filter needs to be replaced.

    • +3 votes

      It's based on how long you turn the fan on for…
      I just vacuum the damn filter, put it back in and reset the timer…

      Now I just ignore the message because I can't even be bother resetting the timer.

      •  

        Does vacuuming a HEPA filter actually work?

        • +2 votes

          It'd help, but definitely wouldn't have the same level of effectiveness. Depends on your needs.

          Everyone in my house is asthmatic except me, so I'm happy to buy a new filter.

        • +1 vote

          It clears the massive accumulation of dust from it to restore the airflow but won’t restore the activated carbon filter properties

          Ours needs a good clean every 2 months

          And the replacement timer in the app is 183 days that’s it, even though the manual says up to 12 months

      •  

        put it back in and reset the timer

          +1 how do you reset the time? Didn't think you could, at least I can't find an option for it. They have an nfc chip in them it picks up on as far as I know

          • +1 vote

            @KRiSX: @KRiSX was looking around and it looks like the older Purifiers don't read the chip, mine's the 3H so I don't think I'll be able to trick it. Fingers crossed :P

    First time a site has automatically charged my paypal without needing to log in or authorise. Couldnt even choose which card i wanted to put it on.

    •  

      Did you check out via PayPal express or tick the box to save your PayPal details previously?

      •  

        Wasnt express. I just did a new dummy order as a guest user and it automatically ticks the box to save your paypal details. I mustn't have seen that on my previous order.

    Don't waste your money. HEPA filters used at home last very long. This bio lab didn't need to replace most of theirs for 10+ years. https://journals.sagepub.com/doi/pdf/10.1177/109135059800300....

    •  

      very interesting read, thanks for sharing!

    • +10 votes

      There's 3 layers of filter, and not all will last for a long time.
      If you actually read the article you linked you'd see that they describe a setup where air passes through 2 other filters for large particulates before it even gets to the HEPA filter. In these systems for homes, there is a single filter and no other filtration stage.

      You didn't even read the link you're throwing around as the "answer".

      •  

        There is AT LEAST one pre-filter on every home air filtration device that utilises HEPA or HEPA-type filters. Xiaomi call it the "primary filter" on the filter posted in this thread, and its sole purpose is to capture the larger particles, thus prolonging the life of the HEPA filter. The primary filter can be vacuumed clean to return it to an 'as-new' state.

        • +1 vote

          The filter is a single unit that is installed in one go. Defining the layers as anything in particular is of little merit and absolutely none in the context of the link OP posted

    •  

      On my air purifier there are 2 other filters before the HEPA filter so this is very interesting. Thank you for sharing

    Currently using the green filter which it does have an extra layer of active carbon filter.

    Look at the green vs grey vs purple:

    https://www.mi-store.com.au/xiaomi-mi-air-purifier-anti-form...

    https://www.mi-store.com.au/xiaomi-mi-air-purifier-hepa-filt...

    https://www.mi-store.com.au/xiaomi-mi-air-purifier-filter-an...

    Look like only the green one have the thick extra layer of carbon filter, the other two still have carbon filter but is thinner and not removable (not that you will remove the one in the green one to clean anyway).

    I wonder if for absorbing odour the green one can do a better job since it has 'more' carbon filter?
    For me, the green one is working well for removing the burning smell last year during the bushfire.

    Mine is 0% and I still let it run 24/7. this is on time when I needed :) thanks OP

      Do you honestly think the machine has the "smarts" to know when the filter needs changing? It's just a timer based on how long the fan is running and on what speed, designed solely to extract more money out of you. It seems it's working, too ;)

      • +1 vote

        I was leaving it like that for about 2-3 months now.
        Just taken the filter out and give it a bit of cleaning, it still does something to the air but not that quick compare to the previous.
        I think 12 months is a good period to start changing the filter.

        I agree with you about the percentage of the filter, it might be just calculate about the air volume running through it and decide it is time to change.

        There is a RF tag at the bottom of the filter where the machine register with the XIAOMI servers somewhere about the status of its filter, might be changing the tags will refresh the life of a dead filter ? :D

        Pretty sure it's just a 6 month timer. Nothing to do with fan speed

        • +1 vote

          I’ve had mine for longer than 6 months and the filter still has life left. So no, it’s not a random 6 month timer.

            @peanut48: Ditto. I've had mine for over a year now, and usually only run it when cooking stuff or the missus stinks out the bedroom with incense. Also have been running it on night mode lately to help with hay fever. The machine says 91%.

      Mine's been at 0% for about a year now. I clean and vacuum the filter regularly. It still runs 24/7 and still seems to be working fine.

    •  

      Hold the rear button for 5 seconds to reset back to 100%. I’ve been using my filter for nearly 5 years. I only use it for dust, so I give it a vacuum every few weeks and reset it.

      •  

        Might not work with my 3H. Did that and only reset the wifi settings

        •  

          Sorry maybe it’s the top button + rear button you need to hold together. My memory is bad

        No. Just pointing out how crappy Kogan's website is, that they list "colour" as an option for an item that doesn't come in multiple colours, and is completely irrelevant in any event.

      Bought like a true ozbargainer.

  •  

    And what's the "Free shipping with first" - free 14 day trial. Ongoing $11.99. Cancel anytime"

    So you get free shipping, but if you forget to cancel, they will charge you $11.99 every - what - month??

    I think there will be a lot of upset people.

    EDIT: That's if you don't use the coupon code

    the one comes with the purifier start to produce a sour smell for some reason. replaced it with an antimicrobial one.

    • +2 votes

      If it smells sour then the carbon filter is full and has absorbed all it can. You could try let it air in hot direct sunlight on a 30C or higher day to help release the gases back into the air. But best to replace

      •  

        thanks for the tip

  •  

    Couldn't pass up the latitude deal on this, preparing for the kogan spam lol

  •  

    I bought a 3H global version. Do I install Mi home with AU as my location or do I still use Mainland China?

    I have a 2S which is set to M.China.

    I guess I can't have them both on the same Mi account?

    •  

      I use AU as the location for my 3H.

      You should be able to change the location for the 2S to AU first (I previously had M.China set for my vacuum because AU didn't exist, but was able to change it over to AU later on) and then add the 3H.

  •  

    Just a note that I ordered these from Kogan during the last sale and they took ages to arrive - approx. 2-3 months.

    Hopefully they actually have them in stock this time around…

  •  

    I have a couple of spares which I haven't used yet in a 2 and 2s - I bought a bag of wrap around filters (similar to these: https://www.ebay.com.au/itm/Electrostatic-Filter-Cotton-HEPA...?) which stop bigger particles on the surface and reuse the filters a couple of times over which seems to be fine - though the 2s reading doesn't usually get above 0.04 unless cooking or such… Tempting to have more spares but running out of space due to ozbargain!!
