Anyone interested in a washable-filter air purifier should check this model from Korea with e-Nano film filter:


I have a similar unit (AirVax) with the electrostatic nano filter thing. Seriously, it's a gimmick. The thing is pretty useless. For one, the fan is a PC case fan, and it's supposed to be good for 33m^2. Even at full speed you can barely feel any air output. The Habanero is rated at up to 75m^2 and it's smaller than the AirVax (looks like they use the same fan, but the Habanero has a thinner filter). It might work in a max 10m^2 room.

I've been running the AirVax almost 24/7 for the past month. All my other filters started turning grey within a couple of weeks. The AirVax filters just have some dust on them. I don't know how the filters in the demo pics are so black. They probably left the machine in a smoke chamber.

Seriously, if you can get hold of a proper HEPA based machine, get one and stop looking at gimmicky machines like these (also things like the Poiema/Airdog). They *are not fit* for hazy conditions.

what about Air Cube? is it good enough?

no experience, also looking around at the many choices... another one on taobao is Airburg, looks cute, use phone to view via bluetooth.

where to get the best ax40 deal now huh

Cheapest was last weekend now the price all went back up already. If you can wait the promo might come again but no guarantee.

Last weekend price was,

HAPPY MALL - SGD 299 comes with 1 extra filter (Ard SGD 70 if order seperately, so effective price is around SGD 229). Now SGD 323
http://www.qoo10.sg/su/62008442

Daiso - SGD 238 (include $15 shipping, no extra filter). Now SGD 284
http://www.qoo10.sg/su/62015850

GoniGlobal - Now SGD 289
http://www.qoo10.sg/su/62020917

If you need it urgent try not to buy from HAPPY MALL as they are located in BUSAN, South Korea, lead time add 1 day from BUSAN to INCHEON (FedEx ships out from INCHEON). Forumer whoooo said Daiso qxpress is quicker than FedEx. I bought from HAPPY MALL on the 29th Sept still waiting for the shipment from Fedex eta delivery this Wednesday.

Well my daiso ax40 using qexpreas reach me in 2 days, the other using Goni send on 29th using FedEx still in incheon.... so ubsay lei

Hope this helps.

Cheers!

Part 1 thread close liao, dunno how to quote =/

Buy the version with Plantower laser particle counter module. (G1 version)
ie As long as your version outputs particle counts, eg PM0.5 xxx and PM2.5 xx, it is G1.

If one is hardcore enough and suspect that high RH is screwing up the readings, give the intake air a twirl with a hairdryer first so that it's way above the dew point, and the readings should be pretty ok. :)


Below pics are done by bro someperson in the 2015 El Nino and Haze Discssions


samo air 247 ug/m3. BAM 1020 150 ug/m3. Higher end ug/m3 reading
Normalise yourself.
BAM 1020 follows a strict calibration timetable routine.

Samo air 66 ug/m3. TSI Dust Trak II 70 ug/m3. Lower end ug/m3 reading.

China ones work, with a certain degree of "OFF" in accuracy. But still work for home use. As long as you can have a degree of reference, it' work.

It really doesn't matter if it's truly 136 ug/m3 or 126 ug/m3. You know the degree of haziness at your spot, and get a trend analysis be it you output into a program (like how Chuanz does it via s/w) or by DIY, up to you.

Home use must be cheap and sensitive/accurate/usable to a certain degree. With a certain ease of use. Else it'd be frustrating.

so you are saying another one B4 (can share link?) is better than this two G1/G3. will search for your review, thanks.

your review this one
Sounds like B4 not so good???

I may have gotten a bad unit perhaps. But it is abit off normal values of the other 3 sensors (2xg3, 1xb4). So I would still prefer the G3 sensors. B4 looks better and can read values from afar though.

Hi imacbie
Can I check how long it took for them to ship you after your orders reach their warehouse?
Delivered by their own courier in Singapore? Any notification whatsoever?

First one all in I think took bout 9 days iirc.
Current one I paid on the 26th but seller did mentioned to me they'll only ship 2 days later.

I not sure it was their courier or not.
But it was a nice auntie.

If budget really tight, think can go for the G1 (seller said more precision than G3) without the nice case @
¥205.00:

but on the other hand, now got sale for the nice case model with sensor at bottom for ¥218, a bit more, looks better:

Keep it in high, switch on air-con to 24 deg C.

With a fresh AX40 filter, is really song......esp in this kind of prolonged + high level haze episode.

BTW, remember to air the rooms at least twice a day. :)

Great Advice! Thanks bro!
