I think it's SGD 109 at BEST.
Taobao original sharp filters cost ~ SGD 80.
imo it's still a viable AP, can put in living room instead of your bedroom.With the review on XM2 by bro tanyj82, I'm Glad I didn't go buy XM1 that day. Think I still prefer my two trusty Samsung AX40...
Low noise quite important.
If need be I will upgrade to the 352X80 for the living room... Solid!
no stock, i chk liao.....VIP voucher only u have...qpoints not many ppl have....
wow half the price of a unit

Thanks for the write up, just as i suspected. Same as the M8088A. Very limited usefulness in usual day situations. It's not due to the SHARP IR LED sensor module though (mentioned before one guy has a pretty good meter based on that), more of the lousy xiaomi circuitry.
But it would come in handy during 2015 levels of haze. That one would show the spike up. I mean, heck.....Sharp, Samsung etc all would as well.
BTW, that one is not PSI, AQI, API, not an index figure. That is ug/m3, concentration.
Hi, do you mean these 2 machines are not useful for normal use? If xm2 under turbo mode is unbearable, so xm 1 will be worst right? Still thinking should i buy from ntuc
haha this is one thing that is sort of stopping me getting one apYou never know... From some of the stories shared in part 1 of the thread I think, one possibility is maybe buy already go back, kenna scolded by elderly parents or unappreciative spouse for wasting money on this kinda 'bo liao' appliance. Maybe they refuse to use, no choice but to get rid of it.
hello guys, is it still worth it to buy honeywell air purifier and step down transformer from Amazon now or better to get it other brands of air purifier locally?
Sent from ? using GAGT
Just got XM AP2 today.
The API shows 39.
After 2 hours running it is now 33.
Do you keep it running or just turn it off ? 33 seems low for me.

I think if i'm not wrong, whether 200 or 330 m3/hr, simply indicates how fast it clean the room and the lowest level it can reduce to, which imo the lowest level won't be that important.
For 24/7 operations, the transformers are known to overheat and blow. Seen it several times myself.
My recommendation is on the XM2. (I also recommend the Samsung AX40)
Not saying that the XM2 is not useful. The XM2's filter cost is great.
Also, the XM2 can do variable fan speed (XM1 is fixed medium), so it'd be useful specifically in new BTO's bedrooms.....whereby it'd be pretty quiet pushing some 150 m3/hr of air, which would be sized ok for that. SGD200 for bedroom AP with compact sizing, energy consumption is good, filter cost great, good styling for the XM1 coz it's shorter esp since in normal bedrooms, cloud mode, sounds ok to me.
A key diff is the XM2's variable fan speed control via the app.
There is a difference in noise in Turbo (simply because the CADR is more for XM1).
They revised the XM2's CADR from 330m3/hr down to 310 m3/hr. Maybe correspondingly JET mode 388 m3/hr down to 365 m3/hr. This is probably due to complaints from the case whereby some Shanghai testing agency tested many APs in the market and found a few units to fail the claimed specs etc.

Key take-aways :
Measurement of levels in a 49 cubic metre room (or 16.8 sqm HDB, 3.6x4.6m or those new 4-room BTO Master bedroom size).
Can you wait that additional 3 minutes (21 vs 18 min) when you suddenly get hit by very heavy haze like 19th Oct 2015's WEST 471 ug/m3?
可以看到小米空气净化器2在21分钟时将19㎡环境下近似500ug/m3的污染浓度净化到35ug/m3以下。两个数字中前者是国家PM2.5严重污染标准的上限数值,而后者则是空气质量为健康的最高限值,也就是说小米空气净化器2可以用不到21分钟的时间将极为少见的严重爆表污染状态净化到健康标准,而小米净化器一代依靠更高的CADR值在18分钟完成了净化工作。小米净化器2虽然慢一些,但效率依然不错。
I have the 美的KJ30FE-NV2. It is CADR 318m3/hr if i am not wrong.
So as you can see, not a lot of difference. XM1, XM2, KJ30FE-NV2 are all in the same ballpark. The Samsung AX40 would still be in the same ballpark probably. You would not notice much of a difference in real life usage, even with a laser particle counter. The leakage from the windows, say whether or not it's closed properly, during a heavy bout of haze makes a bigger difference, as some of us with meters have found out with our measurements in 2015 Unless if you bring in a heavy hitter AP like the 750 m3/hr 352 X80 air purifier, then yeah there's prob a diff.

bro lidat if given a choice, would you get ax40 or xm2 for larger rooms?
