Air purifier?

[Akai Ryu]

At the back after pre-filter I had applied Daiso gas filter, can reduce the dust get into hepa, hope it helpful to created longer life.

just like adding 3M filtrete which will affect air flow.

The small sponge thing got any use anot?

Been curious about this model but the raising vent is both a plus and minus for me

 

[Niaoson]

A little off topic but, any good and cheap dehumidifier to recommend?

Gets a bit stuffy indoors when everything is shut. Other than using aircon, will a dehumidifier also help?

 

[eurofunk]

Operation seems really quiet

Just my short review after 1st for few hours only.
This sharp KCA-40EB comes with Humidify function can help up room clean air with added cooling on room temperature as well, the airflow without noise at all, when 1st run got slighly charcoal smell, after an hour no more smell already, for a whole room feels much fresh now.

That is worth it.

Nice mod..... Putting it in living room or bedroom?

We use it for bedroom only, turn to low fan, can't hear the noisy at all, feels very quietly..

I had the Samsung AX40,

when is the tell tale sign that the filter needs to be replaced ?

I'm using kcd40.... Not bad... Although it's abit costly... But... Worth it...

Yap look at Novita at Q10 just selling $130 only, we bought last week, maybe tomorrow will delivery over to my house.

Abit oversized for a bedroom using this model.... The area coverage Suitable for living room too...

Just curious. How does the AP operate in the different modes? Just fan speed and whether the plasma cluster is on or off?

Huh really? No wonder my AC cut of faster than 1-1.5 hrs, to compare without AP.
AC cut off meant temperature are achieved from the pre-set.

Such as humidity mode and fan mode only, the rest can't function, I guess the plasma cluster would be for normal function as well

gd ma u achieve clean air faster

A dehumidifier definitely helps, but is energy inefficient. U might as well get aircon, cos both use very similar science to achieve their purpose.
Actually the stuffy feeling is because of pockets of still air. U can have a fan blowing directly at u, but it's quite uncomfortable.
A better option is to use an air circulator eg. Vornado. Basically an air circulator is a fan that throws a narrow beam of wind energy over much longer distances. This beam of moving air hits walls, deflects and cause whole room air circulation.

Tried and tested. I point my Vornado blowing at ~45 degree angle at the ceiling, the wind bounces all around, hugging all 4 walls, and the "reflected" breeze moves over my bed, TOWARDS the direction of the fan. And I'm only using the lowest speed setting. No stuffy feeling. The tricky part is getting the placement and angle of the fan correct.
As a bonus, u get to have fun doing airflow engineering.

Yeahhh...SCIENCE, Mr White!

AC + AP + air circulator = Unholy Trinity of air conditioning

Although aircon and dehumidifier use the same science, in terms of electricity consumption does the dehumidifier help to save? According to one of the pictures I saw on Qoo10 for the dehumidifier, aircon electricity is about 6x more than the dehumidifier?

Macham like wind tunnel ah.

On a side note...

Wanna cook?

air con keeps you cool also leh.

 

[otacon]

Can confirm if AX40 has warranty, how long n how to claim warranty? First time getting AP, usually where u r position the AP? N do u all on it everyday even after this haze season?

How much the v tornado? If no haze any other applications?

GXGX to those who just got your air purifier.

(1) Pls for get about the purifier area (sqm). It mostly is marketing fluff.

(2) If you intend to run it after the haze period, pls set it at the fan speed mode that gives you at least 5 ACH / Air Changes Per hr.
This is the recommended levels for allergy sufferers. eg allergic rhinitis, even mild cases

(3) For cases like Thursday kind of haze that got is to have 1-hour peaks of 356 ug/m3 during the wee hours, which converts to an index figure of PSI 404 (1-hr, not 3-hr moving average).....you'd need to close all windows and doors properly, every single one of them, and gun your air purifier in high. Don't have to stuff the door gaps with cloth, not so kua zhang. It is very easy for the small haze particles (as small as 0.2 microns, majority is 0.5-0.6 microns) to just diffuse into the house even with not much wind.

Just to give you an example, with my laser particle counter meter, in the kitchen I have this louver window that has some small gaps of about 10mm for each pane. It's just very small, much smaller than those HDB with corridor and living room has such louver windows as well. In the kitchen, I am measuring some 70 ug/m3 PM2.5 concentration, while in the living room with 3 air purifiers blasting, I am getting about 10 ug/m3. During normal days, I could get the living room down to about 0.2 to 0.5 ug/m3.

So yes, it's that easy for the PM2.5 to "diffuse" into the house.
Bro chuanz has done the measurement during a hazy day of > 150 ug/m3. In approx. 8 hours of shutting the air purifier, the internal PM2.5 concentration nearly equalised to the external levels.


eg Sharp D60.
High speed 396 m3/hr.

Taking HDB ceiling height of 2.9m, the applicable area = 396 divide by 5 div 2.9 = 27 sqm.

Med speed 240 m3/hr
Applicable area = 240 divide by 5 div 2.9 = 16.55 sqm.

My Master bedroom is those new and super small 4-room BTO type = 4.7m x 3.8m = 18.33 sqm.

So medium speed is barely enough for the D60 during normal days.

For the D40, you'd need to keep it in high fan speed.
