    The list of post codes ineligible for FIRST is massive, and I'm on it ๐Ÿ˜ฟ

    I remember in the pre-FIRST days when Kogan offering free shipping normally, my post code got free shipping. I guess they learned their lesson after I ordered so many large items

  • assuming for the 4, not the 3's…?

    • +1

      Other way around. Specs show this is for the 3 and earlier models, for the 4โ€ฆ

      • so is it better to have a < 3's for cross-compatibility?

  • -5

    these only make sense if you have a relatively airtight home, don't open doors and windows often and have poor or non-existent ventilation.
    I've been to some flats in Sydney, on busy polluted streets, where the owners would never open the windows and the ventilation was bad - that would be the ideal use case for this imo.

    If you open windows every day , or have working ventilation, or live in a standard poorly insulate residential with "natural ventilation ", then these are an absolute waste of money.

    no?

    • +1

      They are good for an office

      • don't office buildings usually have forced ventilation?

    • +1

      Also good for dusty environments, despite outdoor ventilation.

      • -1

        like industrial environments?
        what do you mean by outdoor ventilation?

    • +1

      I would've thought being able to get more airflow from the outside would make this more needed due to the dust, pollen and pollution coming in.

      • -2

        my point was, if you have ventilation or open windows, then there is always new air coming in and old going out. These filters will never be able to meaningfully clean the air before it is changed by new air coming in. or
        essentially you are cleaning the air that's going outside anyway. Unless you are in a room with poor ventilation and no, or closed windows, then this just doesn't have meaningful effect.

        They are good for some hospital situations, offices with poor ventilation and closed windows and some old (no or bad ventilation) apartment buildings that are next to busy roads or where for some other reason you don't open windows.

        I'm not saying they are useless, but I think people don't realize how restricted the use-case of these are.

          my point was, if you have ventilation or open windows, then there is always new air coming in and old going out.

          Unless the air outside is bad which you can see here. Parts of Brisbane, Sydney and Melbourne are in the moderate-unhealthy for sensitive people range, while some unlucky suckers in Tassie have the highest levels in the unhealthy range. So both inside and outside of the cities it makes sense to have an air purifier.

          Now imagine how bush fire season would look. I wouldn't be having my windows open.

          • @Clear: I don't understand if you're arguing for or against me. You say "unless" but rest of it seems to be supportive of what I'm trying to say.
            As I have said several times - these make sense if you keep windows/doors closed and don't have other working ventilation in the room/house.
            "I've been to some flats in Sydney, on busy polluted streets, where the owners would never open the windows and the ventilation was bad - that would be the ideal use case for this imo."

            Absolutely helpful in a bushfire season - IF you keep your windows/doors closed and switch off the ventilation.

      They also pick-up dust created by animals including humans, so it can depend on how many animals you have in your house, the type of flooring (e.g. tiles trap less dust than carpet) and how often the place is cleaned.

      Probably more beneficial for people who have allergies.

      Opening doors/windows gives air airflow, but doesn't always equate to moving the dust outside, whereas the air filter will trap dust in the filter.

      If you don't have allergies I would put it in the nice to have category.

    • 5 people dont seem to understand how ventilation works.

      I'm not saying "open your windows instead of buying this"

      I'm saying, if you open your windows, then these kind of appliances are ineffective because they are not sufficiently powerful to process the flux of air and will not increase the air quality in the room/house in a meaningful way.

  • any aftermarket version recommended? the original xiao-mi filter is expensive.

    • Yes. Ebay

    • +2

      any links to aftermarket versions? how do they get around the NFC tags

    • +1

      Don't buy no-name HEPA filters, you can't trust them. They could be selling you a useless paper filter for all you know.

  • +1

    Perfect. I need to replace mine in preparation for inevitable massive back burns, and the potential bushfires.

  • +1

    Can I have an idea the difference it would make between having an old filter (~20%) vs new(~90%)?

    • +3

      About 70% by my math.

      • +1

        Thanks!

  • +3

    Theyโ€™ve bumped it up to $49 now ๐Ÿ™

    • Inflation.

    • +1

      it was $49.99 before as well. Even $49.99 is still a good price actually

      • Yeah I pulled the trigger at $49.99 a week or so ago because it was way cheaper than anywhere else

  • whats the best xiaomi purifier of all time?
