  They normally have it for $379. Coway is a quality brand (I know nothing of their air filters though).

  They all have a HEPA filter which looks much the same in all, but the carbon filtering differs. The big Coway has a carbon foam one, but the other two use carbon granules (I'm not sure if there's a difference in performance). The Winix also has another filter that can catch big stuff like hairs.

  Look at other sellers for replacement filters as they can be cheaper.

  My technique has been to buy a bulk pack of furnace filters from the US (back when shipping was affordable) and cut them to the size of my split system air con inlets (on top of the indoor unit). Works great and really cheap.

    The cadr on an air con will be considerably lower than any stand alone air purifier - they're not designed for the additional pressure. It also puts strain on the fan motor that will limit its life.

      CADR = Clean Air Delivery Rate.
      I reckon an air con has better air filtering as they're designed to serve a whole room. You can certainly feel the air flow better than you can from an air filter.

      Furnace filters aren't really thick or dense, so no notable extra strain.You can get lots of different types depending what you want to filter. It's higher air volume throughput, lower filtering for each pass, but still seems to do it fine. The principles are the same - pushing air through filters. It could be argued that by keeping the guts of the air con clean it helps it. I got about 20 years filter for about $100. In my case mostly for smoke as I'm surrounded by bogans with wood heaters that don't know how to use them.

        This is all just anecdote without running a cadr test with a particulate monitor. Corsi Rosenthal boxes can deliver massive CADR (eg 1600m³/h) but they use 4 x merv 13 filters with a very large space before the high pressure fan. Air cons don't provide the same pressure but they are good at circulating air. I would suggest what you're experiencing is dilution of smoke gases (smells) rather than reduction in pm2.5 particulates. A friend who uses an internal wood fire commented how he found his ducted air con reduced smoke in the house when the fire was on. Doors/windows closed - there was no reduction, just a redistribution into the bedrooms.

          @bargainshooter: Such a doubting Thomas! I'm not sure why you've bought the Corsi things into it. Sounds like something the average person wouldn't have.

          You just said it - air cons are good at circulating air. Stick a filter in there and bingo - you have a decent air filtering system. It ain't rocket science. Mine is not ducted. It's used in a small space about 4x8 metres. It's not being redistributed anywhere. I'm not sure why you doubt that it works unless you're in the air 'purifier' biz?

            @wfdTamar: Not in the biz but have been using, researching and measuring air purifiers for around 15 years. Yes the filters you're using do filter but they won't filter the particles most damaging to health - and pm0.3 - pm2.5 particulates can't be seen, nor smelt. That is all. I mention CR boxes because they use furnace filters but of merv 13 standard.

              @bargainshooter: Roightyo. I'd like to see a comparison of air sampled from lots of places in a room using the air con method vs an air filter. I suspect that the air filter will filter the air around it better, but not the air in the further reaches of the room. I reckon the air con may filter to a slightly lower degree, but more of the room.

              Anyway it does what I need/want it to do at a fraction of the cost of an air filter.

    Also 52db for the smaller unit vs 54db for the larger at almost double CADR - the larger unit has a much higher CADR/dbA m³ noise ratio. Ie: smaller unit has double the noise at same air cleaning rate.

      You'd be looking at the smaller one for a smaller room (obviously! :-) and as one you could run on low overnight in a bedroom. So I'd be looking at the specs on low/sleep/eco. They're all pretty quiet on low though (20-24dB is sod all). The bigger ones give you the option to more quickly clear a room if say, you get home and find it full of bushfire smoke. That's where the air con one is great as it can do that very quickly.

  Does anyone know if the carbon filter is a soft sheet of foam type, or a stiff one that is impregnated with carbon?

  Ive had one of these for about 3 months. It’s very good, it’s sensitive to any impurity, i leave mine on the auto setting. It revs up at the slightest cooking from the adjacent kitchen. This would be good for people in units also to avoid cooking smells to creep into the lounge. The carbon filters are stiff, not sure about what that means for quality.

  • 

    wfdTamar on 23/12/2023 - 17:24

    Ah thanks. I have a filter on the toilet cassette on my motorhome that use that stuff. The filters are about 150x90mm and cost $25-40! I could cut up a Coway filter instead.

  wfdTamar on 10/01/2024 - 04:58

  I did buy the Coway the OP posted. Also the genuine filter replacement pack I linked to.

  The carbon filter is pretty pathetic being a mere 5mm thick and not very dense. Just a sheet of foam. Not much actual carbon. I can’t see it being much use. The hepa filter is a pretty standard one. Would be nice to have a remote control. I don’t know how this one awards - maybe the only unit in its class, or bribery?

  I bought a full pack of filters but only one carbon filter turned up. Amazons solution is to return and refund. I want what I paid for! One huge drawback of Amazon is you can’t talk to the seller (like on eBay).

    One very important point is the CADR test is in a small room that has two fans mixing the air. WTF! This is very deceptive. I suspect there may be a clean zone in the immediate vicinity of the air filter, but other air in the room does not get cleaned anywhere near as much and the fact they have to circulate the air with other fans for testing proves that. The testing should be done with no other air movement devices. This is why using the 'filter on air con' technique would provide superior cleaning to just an air filter alone. An air con has much better air movement through the whole room.

  wfdTamar on 16/01/2024 - 10:57

  I'm returning mine. The carbon filter is pathetic so it'll be fairly ineffective for smoke. They also can't get their facts straight - the listing and their web site claim 99.99% filtering, but the manual and filter sales listings 99.97%.

  I think it's as good as any other for general filtering (i.e. pretty average), but not the right sort for smoke. You want one with a lot more actual carbon (not just a carbon impregnated thin bit of foam which is all most have).

  I really think the furnace filter on split air con, or a DIY job with a box fan and filters will do a better job, but without fancy lights and 'sensing' activation.
