    I just made a forum post maybe 30 minutes ago about this exact topic.

    My concern isn’t for the units themselves, the filter replacements are fkn expensive. Has anyone figured out a supplier that could sell them cheaper? I’m trying to find a cheaper alternative for my Kmart one - $68 for 3 filter, not terrible, but a couple replacements and I could justify buying another whole new filter unit.

      Ikea has extremely reasonably priced replacement filters, even if their air purifier units aren't the cheapest. I'm going to buy one of theirs when the filter in my current unit air purifier expires

    Filter longevity is a complex calculation - if your air is relatively clean, they will last much longer than the recommended 6-12 months. They don't use electrostatic layers so the only thing reducing lifetime are things they will trap to protect your lungs. Most HEPA filters can be used reliably much longer than the stated lifetime - they don't really degrade, only get blocked - so they become more effective at blocking particulates, just not as efficient as airflow is also reduced.

    Also, they sometimes go on sale - last sale was 50% off - 2 filters for $149.

    It reminds of buying ink for printers. Would be happy to pay more for a air purifier as long as replacements are easily sourced and more cost efficient.

      doobey1231 on 12/09/2023 - 13:29

      Yeah bang on, there was a few years where I did the maths on some cheaper printers and it worked out mor economically viable to just buy a new printer that came with a pack or two of colours included, than it was to buy replacement cartridges for the existing printer. Mind boggling.

  How long do the filter last? They have the unit plus 2x filter replacements for $549 which comes out cheaper than this deal if you buy the filters separately.

    They are seriously trying to sell filters for $275 each which need, by Samsung's recommendation, replacement very 6-12 months?

    This looks like the injket cartridges and coffee pod business model.

    FWIW, I have tested some filters (Xiaomi) far past their recommended lifespan and they've still been fine, same probably goes with most if not all HEPA filters, but I do install additional prefilters to keep out dust.

    • 

      csjc on 12/09/2023 - 11:18

      Nah it's $275 for 2. The unit uses 2 each time. But yea it's pretty expensive. I might just get the unit now and hope there are some sales for the filters in future.

        Sales on proprietary-sized replacement parts sounds… optimistic. In fact, even the assumption that Samsung will still be selling the right sized filters in 5 years times seems a bit hoping for the best. More likely they'd have just ditched the model after a couple years, then ditched stocking replacement parts a couple years after that.

        If price is a concern, you'd probably have better luck looking for something of a compatible size on Ali, but filters are probably only available for the most 'popular' purifiers.

        • 

          bargainshooter on 12/09/2023 - 13:06

          @rumblytangara: Not a very researched assumption - ali do sell this size of non oem filters (it's a very popular model) but the filter size is identical to the ax32 model filters (marginal mm difference in width). And what's a non proprietary air purifier size?? Aren't all commercial hepa air purifiers proprietary in size? These ain't MERV furnace filters.

            rumblytangara on 12/09/2023 - 13:37

            @bargainshooter: Not very researched as I don't place much faith in Samsung for a product like this. They're fans with filters, but I think Samsung is likely to change models faster than other brands.

            Perhaps I should have said long-term available instead of proprietary. My proprietary filters have been available for over a decade because the companies that I chose still make them, or the model was so widespread that third parties still make the correct sized filters.

            If there's a marginal width difference with other filters, I would want to test for air bypass before trusting the new filters. Especially as this Samsung design looks like it blows air in from the back to push the filter away from the housing. Slight mismatches in size can make for a lot of air bypass around the filter, and to fix it you'd have to use some combination of tape or foam blocks.

              bargainshooter on 12/09/2023 - 14:16

              @rumblytangara: Incorrect - it pulls air from the front through the filter. Not sure how you made the contrary assumption. There is no difference in width and height and both use a foam strip around the filter media. Very tight fit. Much better than similar top of the line winix and sharp purifiers. Xiaomi (your reference) filters have been unavailable for many consumers in recent months - there is no guarantee from any manufacturer but 3rd party filters are available for this model.

                @bargainshooter: My references are iqair and Austin air. They've run the same filter formats for over a decade. Also Sharp, but my 2010 model went out of stock for filters a couple years back so I had to go third party.

                I've also got a bunch of spare Xiaomi units and filters kicking around. I don't consider them as a reference for anything - they are essentially cheap and disposable.

                Though these days, all my purifiers are sitting around unused. I'll fire one up if there's a nearby fire (one day so far this year)

      How's someone going to review a filter? They'd need a particle counter and a VOC meter, which very few people have.

      HEPA filters are not exotic tech though- just a polypro mesh. It's personally not something I would worry about. As long as it fits and doesn't smell terrible, it's probably fine.

      • 

        y2k on 12/09/2023 - 17:34

        Yeah, just wondering if I was missing something about the material that some sciencey/engineering brain might know about. I found science umpossible in school.

        I do wonder how CHOICE and others measure their stuff (they have a separate VOC rating) too, as it seems hard to be able to verify a lot of the stuff that's on the packet. Their site says " The pollutant (dust, smoke or VOC) is introduced in a controlled way into the test chamber and mixed into the air, then the testers measure how fast it naturally precipitates or decays from the air. The chamber is then cleared and the test repeated, this time with the air purifier running. We calculate the percentage of particles removed by the air purifier and compare this with the natural decay rate measured earlier. This tells us how quickly and effectively the air purifier is clearing the air."

        They don't seem to mention what instrumentation they use.

          @y2k: Choice is not worth paying attention to imo. Anything that they've tested in an area that I have some vague knowledge in and I'm totally amazed at how half arsed they seem to be. So I don't trust them for anything these days.

          They're just going to use a particle counter, you can buy expensive ones and you can buy cheap ones. But it's pretty simple- anything that moves a crapload of air and is HEPA-rated will be good, so long as you can put up with the noise. It's really simple and non-complex, there is no magic to air purifiers- literally fans with a filter, and you just get the biggest ones you can - Big fans run slower to move more air with less noise. Big filters let more air through with lower backpressure, and last longer.

      • 

        bargainshooter on 12/09/2023 - 22:19

        Everyone should own a particle counter given climate predictions (and observations) but that's just my perspective. We had outside PM2.5 levels over 95ug/m3 today (without any accompanying smoke haze) and that was from "hazard reduction" burns over 80km away.

        • 

          rumblytangara on 12/09/2023 - 22:35

          @bargainshooter: I own two :)

          But I almost never bother turning them on here as the air quality is so much better than what I'm used to overseas.

          We had backburning earlier this week, so I tuned one on, and it was a bit of a nostalgic moment, it was like a typical reading from before I moved here.

          That was the one day I ran an air purifier here.

      mrmc on 12/09/2023 - 18:02

      yeh, no negative reviews at least, hopefully the samsung purifier itself would be able to pick up on the quality of air passing through?

      • 

        rumblytangara on 12/09/2023 - 18:49

        Wut? The Samsung should be monitoring the quality of the ambient air in the room, not the air going through the HEPA.

        (And I wouldn't particularly pay it much heed anyway.)

      Not sure if I'll pull the trigger on this one, but it's funny thinking of buying a pricey air purifier and then getting cheap unbranded filters. The purifier unit itself is basically just a fan, dirt cheap and horrendously overpriced for what it is. All the work is done by the filters. The filter, on the other hand, is purchased by trust, because most people don't have a way to actually verify that the filter performance is the same or similar to the original filters. If I bought an unbranded 'compatible' filter on Amazon, I probably wouldn't be able to tell if there's actually a real HEPA layer inside the filter, my only hint would be on the day the air quality actually is bad, if the PM2.5 sensor in the unit doesn't decrease by as much as it should. The whole point of getting a purifier is so that it actually does its job at cleaning the air. In that respect, I'll look for a deal or grey import genuine OEM filters, but wouldn't get a random alternative

        HEPA filters are low tech and have been around forever.I would not worry about them. I have tested probably a dozen various cheap HEPA filters from Taobao/Ali with particle counters, and they have all without exception been fine.

        They seem to perform just the same as the fully branded ones- none of them are 100% effective. Well, with one exception- the IQAir ones are 100% effective for PM2.5, and they are marketed and priced as such.

        On the other hand, it's surprising how big a difference the fan part can make. Some of them are terrible and generate unpleasant noise profiles. I've personally found that a big differentiator is also how many speeds you can set as it lets you fine tune noise beyond a high/medium/low setting.

    Looks like the ax32 filter. Nice unit.

  BlueGlowOne on 12/09/2023 - 13:28

  Do check in store as this is a large unit. The AX60, besides a smaller form factor, has roller wheels which may suit some buyers. Both are not 360 degree units like some others.

  The filters are expensive however easier to source (unlike say Sharp) and some can be washed a few times before replacement. Replacement time depends on how much you use it and how bad the air quality is.

  One nice thing about the larger units, besides floor coverage which I halve to get the real number, is that they are generally quieter as the larger fans spin at a slower rate however again do check in store and have them plug it up for you to test and try out all the functions.

  I bought the earlier Philips deal with a extra filter under promo and my allergies 🤧 have dropped significantly since and the back burning these days makes it’s usefulness a bonus.
