[mikeeeey]

Didnt know that increasing the thickness will help in increasing airflow. Learnt something new

If you look at a HEPA media, it's pleated, like a folded paper fan. So increasing the thickness = more surface area when unfolded = less restrictive to airflow (all else being equal)

Wah... The xiaomi looks like a good deal. Including shipping should be less than S$250.

[mikeeeey]

The filter is also available from the online TMall Official Xiaomi shop. Think in addition to the air purifier, get an additional 1 or 2 filters as backup. Then dun have to buy filters for the next.... 1.5yrs to 2yrs at least?

Honeywell 50250 chuanz already sold away and replaced with a Novita 620. 50250 ish 58dBA. About 450m3/h.

Samseng AX40 45 dBA. 323m3/h

[WussRedXLi]

Morris i think Giant sell 19.90.

PowerPac Japan Home selling 16.90. I think wee bit weaker than Morris.

 

[drifting]

Hmm any root cause for the haze? Or is it just the "normal" forest fire

Yah. Got people complain about the sound at hi-speed.

But Honeywell is the only one with a true head on head fight with Xiaomi in terms of airflow? Maybe the only point of contention is the sound at hi-speed.

Honeywell is easily twice d price of d xiaomi?

Sigh...

Due to the sound of the Xiaomi, give me $200 incld 4PX -> SIN forwarding, i also need to consider. $99 i will buy for fun. Basically it's a 250+ m3/hr AP with a turbo mode @ 406 that needs to wear ear plugs during operation.

This 480 m3/hr one (CADR somemore) used to be $399. Including 1 extra filter. (filters can be purchased locally)
Can PM them if can discount. 58 dBA.

The 3M brand HEPA filter is high quality enough to filter PM0.1 Ultra Fine Particles and give a measured CADR of 480m3/h or 282 CFM.


Blueair 650 is 860m3/hr i think. Another US Brand Airgle also v powerful. All are ex.

Or go Taobao get the China models AX60 and AX70. 700-800 m3/hr. About $800-900.

Most powerful one i have ever seen is a Coway (South Korea) model AP3xxxx on taobao. 1200m3/hr.

But seriously for our normal use for Indon biomass smoke, taobao filter and a 300m3/h original spec machine is more than enough. Unless the patient is like 2yrs old with operation due to Congenital Heart Block etc.

I tumpang people hooting TB. EAch filter RMB68 nia

moi humble and taobao hooted 2x HEPA filter taped behind a fan

Great airflow, make sure the tape is done up nicely.

Advantages??

2 filters with good surface area to trap particles.

Fan blades don't get dirty.

Best part, pricing is 1/4 of any conventional filter you buy with less surface area.

I've been using this over a year. It works well. If a/c is on during hazy day, I turn this on in the room. You can smell the difference outside where its hazy, the air is different.

Filter is already dark grey now. Gonna change a new set.

air purifier is not like vacuum cleaner when the job is done you can turn it off after like say 30-45mins..

or at least for me, i leave them on thru out the night or few hours to work on the air quality in the house. so i can't imagine having a 'vacuum cleaner' volume turned on for so long. watch tv or trying to slp will be a problem.

Yes...must be constantly on, as measured and confirmed by a laser particle counter. If not serious use, can thottle down speed.

No AC. Its not cost effective as the area to be cooled is relatively large in addition to the 2 small corridors which are like dead areas. Would rather AC the rooms for long periods.

Will need at least 20k btu/h for 4 rm and mid 20k btu/h for 5 room living room.

 

[chuanz]

But if you didn't fix AC (living room, etc), once move in cannot regret liao...
