Air purifier? - Part 2

[WussRedXLi]

Currently Xiaomi Air Purifier Gen 1 is on offer, S$115 / S$129, I am tired of AX40 due to the need to clean the pre-filter which collects alot of lint that I find a hassle to clean.

My question, if any experts here can enlighten me:

1. Is there any pre-filter I need to clean on XM1 or XM2?

2. Can XM1 and XM2 stay on high mode 24/7? I read that XM2 will auto revert back to "auto" after certain time, but not XM1.

Why is XM2 favoured over XM1? My main concern is XM2 cannot stay on high mode for 24/7 (like my AX40).

Thanks!

There are prefilters on 99% of the air purifiers out there. This is a plus point actually. There are also very similar prefilters on 100% of the aircon FCUs out there. It's just a 20 seconds job with a vacuum cleaner, i do it whenever i vacuum the floor coz surely would pass by the APs.

If no vacuum, just go to the shower or service yard and blast it with the shower head/hose. shake it a bit/pad it dry with a cloth, install back. If you want you can air dry before installing, or just install it while it's still a bit damp.

Yes, there are "net" prefilters on the XM1 and XM2, these are located on the cylindrical HEPA filter units....it's "built in".

If there are no prefilters, all that lint would be stuck on the HEPA filter's pleated surface and it won't be easy to vacuum it then. You'd be "using up" that HEPA filter like 10X faster than it ought to be.

Aircon FCU pre filters, a bit lehceh, need to use a chair so not cleaned as often.

Trust us, you don't want the xm to be a blast mode.

I only can put my xm1 at high (1 level below blast) out in the living room when I am in the study. That was during the great haze when my apartment was in locked down mode.

thanks for the reply. i understand that XM1 is loud, i probably will keep it in M or H mode 24/7. Is it true that XM2 and XM Pro cannot be set to M or H for extended period of time?

For XM Pro, initially maybe cannot? Not sure. But after update, I tested with Fan speed @18-31m2 coverage, it didn't toggle back to auto mode. Tested running for whole day overnight. But I didn't test the highest full blast speed.

For XM2, not sure if update will do likewise or not. No longer has XM2, so unable to try it out.

wah... really cannot stand the noise of XM1 at high speed.

Any statistics on the CADR of XM1 at various speeds? I can't find it online leh...

High speed is noisy. Jet mode I doubt anyone will be keen to let it run.

XM2 and even Pro is also "noisy" if u set to the high/max speed. Among these 3, XM1 is the noisiest, followed by XM2. Pro is more "smoothing" to my ears. At current settings, I think I noticed my fan sound rather than my Pro sound.

Use the app pm2.5 readings to monitor n judge urself whether the Low or Mid speed is sufficient to maintain or reduce fast enough for ur room/area.

So far, mid speed is sufficient for me during recent "hazy" period. Haven't put into real test on real annual haze. Last time was using AX40 - this one quieter and Honeywell - this one noise even... (no longer have them now) .

believe honeywell is noisy in most modes?

"Sound" is noticeable even in Low mode.

Airx A7
Too bad too expensive. Looks to be of a efficient design (noise : airflow ratio).
Laser particle counter built in etc.
RMB 1999 on offer during sales like 11/11 or 12/12.
If they could bring it down to 1500 or even 1700 then it'd be a pretty competitive product.

Any thoughts/feedback on the XiaoMi 3rd party filter offered by Passion? Compared to the Green filter by XM, is this 3rd party filter as good? Going for $34.70.

So thick. Will affect the "air flow" or not? Might as well stick to the Xiaomi enhanced green filter? $39.90 - only few bucks more. Free delivery unlike passion still need additional $3.49 delivery charge, unless u opt for free shop pickup.

Comparison
Passion + delivery: $38.19 / $34.70 + self pick
Xiaomi enhanced green + free delivery: $39.90
Price difference only $1.71 / $5.20
