Hello, this looks like a good deal. JB Hi Fi and Officeworks are selling for ~$500
CamelCamelCamel.
That's from a different seller. Change to Amazon.
Looks like i had to change my address
The prime z3000 is Not available 100km from Melbourne but the prime z1000 is. Normally can get prime offers must be an error.
Thanks grabbed 3000 getting delivered elsewhere
Grabbed one. Thanks OP
nice find OP. Got one!!! Thank you!
Does anyone know if the filter easy to find and not expensive?
amazon sold them ($55 an hour ago) but just sold out
Thanks. Sometimes the filter could be a block for long term use. I have an existing machine with a different brand. It's very difficult of purchasing a filter.
Not “True” HEPA?
Need more. What do you mean not true hepa?
That article is just…off.
HEPA is HEPA (there are varying standards within it, but the standard I've seen applied to every filter I've bothered to look at is H13 https://en.m.wikipedia.org/wiki/HEPA)
"True HEPA" seems to be more of a marketing term created because of another marketing term- "HEPA Like". The first term just means 'proper HEPA filter and not something dodgy' and the second team means 'it has some kinda filter, dunno what kind.'
So if it says "HEPA" on it, that's fine and inclusive of "True HEPA". It's like saying "True Kilogram."
-Airbro.
From Trusens' webpage - Purification Levels:
UV, Carbon Filter, True HEPA Filter, Washable Prefilter
I think he got confused between Z-2000 and Z-3000. The 2000 has HEPA
Correct! My suspicion aswell.
Ordered one, thanks for the deal!
Thanks OP, price matched and collecting from JB HiFi.
It's a very very loud purifier for the cadr it delivers. The ikea $199 purifier has a slightly lower cadr at max speed (260 vs 309m³/h) but is much, much quieter (53 vs 66dBA)
video reviews say it operates at 45dB
That's the auto/low setting where it's not doing much. The ikea version is about 32dBA at a similar cadr. Likewise the ax32. The manufacturer clearly states the noise range.
i guess auto is a good setting to leave it in so it can just do its thing?
I reckon if you ran the Trusens at a lower speed to match the 260 CADR, it would most likely have a very similar noise level as the IKEA air purifier. There are all just fans forcing air through a HEPA filter, there's not much they can do to make the noise quieter or louder — it mostly just hinges on the fan speed. That's why I always advocate manually setting the desired fan speed, it gives you a lot more fine grained control.

With noise, there's still a bit of variation between models. AC powered fans will often have only 3 speeds, and the big jumps between speed can easily go from "quiet but slow" to "decent airflow but sounds terrible". I've found two specific models to suffer from this- SmartAir (which was a huge bummer because I corresponded with the designer and he was talking about acoustics and fan design) and the Austin Airs which use a metal body which resonated like crap (again, a bummer because they are one of the two manufacturers who put a decent amount of filtration in for VOCs).
I've found that DC fans tend to be a lot better simply because they give more than the basic 3 speed settings- this is a huge strength of the Xiaomi that everyone seems to love here.
Good point about the AC vs DC, I only use DC fans and air purifiers so I've forgotten about the downsides of an AC machine. Yeah being able to precisely control the speed is very important IMO. Someone said the Trusens only has 5 presets you can choose from, which is a bummer.
This looks like a good deal, though I'm still waiting for the Daikin MC40 after reading about it ramping up when it detects a fart. Can't find any deals since jinkerjinx's post last year.
All air purifiers with voc sensors do this…
Do you have any other recommended units from the Ikea one you mentioned? I got the impression the Daikin one did the VOC detection/ramping up in response particularly well.
That's just marketing… I'm not aware of any that don't pick up VOCs quickly. VOC sensors are like $10 cheap retail.
The samsung units are probably my pick. The ax90, though large, has a cadr of 703m³/h at 54dBA. The ax32 has a slightly higher cadr than this trusens at 51dBA + you can connect them to your smart home systems. You can connect the ikea models to their standalone air $49 quality monitors.
@bargainshooter: Most purifiers don't actually have VOC sensors and rely on particulate sensors. The AX32 for example doesn't.
@TheContact: I don't know if the ax32 does or doesn't but the ax90 definitely has one. All the winix and sharp purifiers have them. So any that have VOC sensors will react similarly.
@bargainshooter: Thanks for the recommendations. I was going off the comments from Ozbargainers more than any marketing. I'll look into the Samsungs.
I have the daikin, and I love it. I also have the IKEA Starkvind, and that's no where near as sensitive.
@Droz: I believe the Starkvind doesn't have an inbuilt VOC sensor (which would explain why it's not reacting to VOCs) but can be paired with the VINDSTYRKA air quality monitor to trigger based on VOCs.
Argh not working with TruSens Smart App *Available only with the Z-2500 and Z-3500 Smart Air Purifiers.
A deal breaker for you?
Kinda I'm an IoT nerd.
Oh? 😅 HackRF One Portapack H2 or Flipper Zero? 😁
I have 2 of these in my bedrooms. Put it to sleep mode and I cannot hear anything, but when put it to Auto, it can get really loud sometimes.
Can't you just set the fan speed manually? That's what I do on my Xiaomi 3H. The factory presets tend to be too quiet (doesn't actually do any filtering) or too loud.
Yes, it has like 5 settings for fan
We had the 2000 and then bought the 3000, really good purifiers, I just lock them at speed "1" then night mode for a dim panel and they do a great job.
Problem is the filter where do you get new ones?
I get mine from Amazon, have found sets of spares for both models, or iirc JB-HiFi stock some too. Amazon definitely had different types to suit certain conditions better, like smoke, pets etc.
Did anybody price beat with OW?
Call me pedantic or am I missing some other use
I think is this even necessary in Oz
unless you're living in some hubhub of a CBD? Most of Australia even in big cities like Sydney has very clean air and I have been in a few Asian and US cities to know the difference.
Yeah, you’re pedantic.
Was definitely expecting this 😁
Pollen, dander, people with allergies, people who don't want to develop allergies, people who don't want to develop asthma, living anywhere near people who use diesel engines (major source of pm2.5 particulates and NOx) or use wood fired heaters, hazard reduction burns, bushfires. You can't smell most of these pollutants and just because other cities have terrible air quality doesn't make poor air quality here not poor.
Fair points on pollen and allergens and I see that's a good use case for someone who is prone
but also had a look at Sydney AQI is Google which is mostly green and I believe data as a whole is coming from various sources so for me particulate matter is definitely not a worry and I live few kms from quote a busy CBD of Parramatta
I think it'd benefit people who live close or next to a busy road, as in my case.
Google air quality monitoring isn't really a thing, so it's meaningless unless you can interrogate the numbers and identify sources. And if you monitor particulate matter you will start to understand how inadequate those various sources are. For many, air quality sensors are nowhere near where they live/work and air pollution isn't a check once forget thing. Air quality can be substantially different 30m up(many sensors are placed up high) to what's on the ground. And poor air quality can spike suddenly and dissipate just as quickly without triggering any alerts on official sensors. Our EPA air quality recommendations are also way out of step with US EPA and WHO - and they were introduced just after the 2019 fires as a way to placate people. Beijing made similar changes to their AQI recommendations to give people a sense of security.

Can you provide a source for this?
I've had a quick look for the index explanation and the best I can find is https://www.iqair.com/australia, which just says that Australia created it's own indexing system (fair enough) and that it easily meets WHO standards most the time (excluding events like bushfires).
I'm usually using the IQAir site for air quality info, as they crowdsource their data from lots of sites (i.e not a government tower 30M up), and they use the US AQI standard as seen here: https://www.iqair.com/au/australia
Most times I look on there, the US AQI figures are pretty good for me.

This is certainly true, it's always comical to press a button on a monitor to flick between US and Chinese standards and see the huge difference in reported quality for PM2.5
Okay, here's some actual point in time data. This was taken on a walk to the post office just now. PM2.5 counts as micrograms per cubic metre.
Indoors (sealed environment, no filtering): https://imgur.com/a/u8qKR69
Outdoors 100M from major road: https://imgur.com/a/e2V84B1
Pacific Highway Sydney: https://imgur.com/a/4J8tKSi - this was the highest count I saw. Moderate traffic for peak hour, moderate wind.
When I flicked into the US AQI display, I saw anything from 1 to 13. Which is inline with what I see in the crowdsourced data.

@rumblytangara: Pm2.5 mass sensors aren't that sensitive to road pollution. It's the pm0.3 counters that show how bad it can get. Pm0.3 particulates don't have as much mass as pm2.5 and a huge increase won't be registered on a pm2.5 mass sensor. Eg diesel engines emit pm0.3 to pm1.0 and an increase from 150 particles to 450 won't show an increase on a pm2.5 mass sensor.
@bargainshooter: All that's well and good, but off memory AQI measures (which are what you've been talking about) are based around PM2.5, PM10 and gasses. I did ask about your assertion that the Australian standard is a political fabrication but you have just ignored that.
I offered some actual real life quantitative data here, which is clearly incomplete as it can't show or nitrous or sulfur oxides which are also part of car emissions. But it's a start, and it's concrete - feel free to put up some of your own real data rather than moving the goalposts through hand-waving theory.
diesel engines (major source of pm2.5 particulates and NOx)
You brought up the measure of PM2.5 coming from engines and AQI inadequacies, but now that someone has measured it and put up photos, you shift to PM0.3? Almost no studies cover that, the HEPA standard doesn't cover it so nobody can show how filters work with it- looks like you're just throwing everything at a wall and hoping that something sticks. Show me one household filter that is rated to cover PM0.3? IQAir might (I have one in storage and recall that it goes well beyond HEPA) but I've never seen another manufacturer make any similar claim.
My interpretation of the measurements that I took were that even next to a fairly busy road, the presence of a consistent moderate wind is enough to dissipate roadside pollution (as measured by AQI standards) very effectively. This is online with what I've seen overseas in might more polluted cities- favourable weather patterns often override purely local sources.
I kind of agree w you even though I now own 2 air purifiers since I live in/nearby the city.
I read this news article just today
https://www.theguardian.com/environment/2024/mar/19/air-poll…
Apparently we are pretty lucky!
its gone cheaper now as Bushfire season is over
Nope, just clearing not so good stock.
bought at $249 during black friday last year, was the lowest.
Really like mine, not bad actually!
