    Does anybody know if the Air Purifier 4 Pro uses the same old model of HEPA filter as the Xiaomi 2/3/3H, or is this using a different and bigger type of filter? It's really hard to get solid info on this, the specs don't seem to mention it.

    [update] ok I think I've answered my own question: it seems the 4 Pro uses a newer, bigger (and more expensive) filter which lasts 50% longer than the old smaller model:
    https://xiaomiplanets.com/xiaomi-mi-air-purifier-4-pro/

    There's some marketing sites/reviews which claim that it uses the same filter as the 3/3H, but that looks to be complete BS.

    It appears that the 4 Pro uses the same bigger filter as the Pro H model:

      would you buy the 4 pro? weighing out the benefits and costs

        Whats the difference between 4 Pro & Pro H?

        • +1

          Pro H better

          • +1

            @nico8amy: Why is Pro H better? isn't the 4 Pro newer?

            • @yoshipau: 4pro is an upgrade from 3h. But pro h is their top line.

        • The difference between the 3 and 3H is that the H comes with a HEPA filter. You'll definitely want a HEPA for maximum efficacy. All the other filter types won't do much more than remove dust. I'm assuming the 4H is also the one with the HEPA included, but I could be completely wrong.

          You can always buy a HEPA filter for them later if it doesn't come with it, but you may as well use them from the start.

        If I had to start from scratch, I'd probably get the 4 Pro. But I'm already invested in the older existing Xiaomi ecosystem as I own two of the Xiaomi 3H air purifiers (and a bunch of spare HEPA filters), so it's not worth me getting the 4 Pro and having to buy a bunch of new, different filters for that.

        The 3H works perfectly for me, I have no complaints at all. It's brilliant, and the HEPA filters are very affordable (cost around ~$30 each when on sale).

        • So can the new HEPA filters be used on the older Xiaomi purifiers?

          • @frugalfamily: nah the "new" Pro filters are much bigger, because these Pro machines are much bigger. It's hard to tell from the photos, but the size is considerably larger.

            What makes it confusing is that (unless I'm mistaken, somebody correct me if you know the full details) some of the older Xiaomi Pro air purifiers use the smaller, older filter size. Where the Pro H and the 4 Pro use the new bigger and more expensive filters.

      Thanks for the research!

    • +1

      4 Pro uses size 5 filter

  • How does this compare to winix Zero pro 5-stage?

    • +1

      Winix better but lack app control smart functions

  • I wouldn't pay that much for an air purifier filters out only 99.97% of dust, pollen, bacteria and other particles in the air.

    This customer paid full price $499 and wasn't happy about the performance of this model.

    Dust Sensor doesn’t work, extremely loud…waste of money
    Reviewed in Australia on 2 August 2021

    Looks good and stylish but is pretty useless. Yes it will do a very large living area but you will need to put up with a jet engine sound as it’s required to run on full speed to clean a large area. The dust sensor doesn’t work so speed doesn’t automatically increase. If you Google Xiaomi Dust Sensor you’ll find almost all of them are defective. It also doesn’t have a VOC sensor so the formaldehyde sales point is worthless as the machine can’t actually detect it. I can’t return it as I threw the box out otherwise I would.

      Yeah I just bought two 3H's and both PM2.5 sensors don't work at all unless you spray something directly into the sensor otherwise it doesn't kick up at all regardless of what's happening. Have to run it on manual and it's quite loud for a bedroom/lounge room. I have read similar things on the 4s and 4hs so be careful when buying.

      That's a silly complaint from that customer, all consumer grade air purifiers suffer from the same problem — because proper particulate sensors cost hundreds of dollars in themselves, so a cheap machine will never have a super-sensitive sensor in it. You work around this by manually setting the air purifier to run at max or near-max power.

      And yes, air purifiers are very loud when operating properly — that's how air filtration works, by forcing air through a HEPA filter. You can't have a quiet air purifier that still does the job correctly.

      Air purifiers are kind of a niche product, so I suggest anyone who is interested in getting one do some serious research before buying. They don't magically solve all problems, and they definitely are not quiet. I own two of the Xiaomi 3H models and I find them to be excellent, and good value for money — and yes, you have to manually run them at either 2/3 or full max speed for them to do their job, like every other air purifier.

      For the 3H when running at max power, expect noise levels to be around 58-60 decibels at a distance of 1 metre, so if you're having a conversation with someone in the same room, you'll definitely have to raise your voices. Don't expect to enjoy watching a movie/TV without closed/noise-cancelling headphones while running the air purifier, not gonna happen.

      Here's a good video I came across while doing my research, gives a good primer as to how an air purifier works, and what's important:

      • I've essentially bought one to keep in reserve for fire season.

        Will see how it plays then.

        One thing not mentioned is where to put the air filter. As much as possible, put it in a centralized location with lots of airflow. Hiding it away in a corner will not do much.

      • +1

        Exactly. You can't expect the fan to suck in a large amount of air in a large room without some noise. It's not necessary to leave it on the highest setting anyway. Once the air has been cleared on high setting, just switch to low to maintain constant circulation.

  • is the keyboard any good?

  • +1

    Do these purifiers resume operation when power returns after power is cut? And will it remember last used settings?

    Planning to set settings to max fan speed (manual mode) then using a digital power timer to automatically schedule the purifier on and off. So wondering if it will turn back on after power is restored and if it will remember its last used fan settings.

    • As far as I can tell it stays off after power resumes. Can't you just use the Xiaomi app to schedule the power on/off times, instead of using a separate power timer?

      [edit] Just tested it on my Xiaomi 3H. Running at max, then power off at the wall point, then power back on. As expected, it remains off (idle mode, display is off) after power is restored. I can't imagine the 4 Pro would behave any differently to the 3H in this regard.

      I also wouldn't recommend hard powering it off regularly, that's gotta be rough on the electronics/components.

  • Bought the keyboard (brown switches) from this seller on Black Friday, just got it and they sent me the TKL one instead. Trying to get them to send me the right one atm.

      have you tested it?

      how much paid?
