Didnt really use for long hour, wife use it for make up in fitting room max also 1 and half hour

Normally will stay at study room more (study room just outside fitting room) , so max also 2hour+ per day to update forum + Facebook stuff, is that ok?

Don't know how your room design. If its close area with poor air circulation humid will build up, and not good for wood and cloths. You get the mushy smell and promote bacterial growth, if you have window or open area that can give good air circulation, just leave it open after use and humid dry out.

Humidity is not an issue for Malaysia, as it is very high already, so no such thing of humidity build up.
If it really build up like you say, now is 80-85%, how much you want?
Seal the whole room by closing windows and doors also resulting to poor ventilation, this is worst than "poor circulation".

i have decided to go for MHI SRK10YL-S for my master bedroom.
Lazada is selling RM1410, is it good price?
any advise if I should get from them?

Yes ventilation is a better term to use. Putting humidifier in already high humidity temperature we have here will cause more problem without good ventilation.

Why need to use humidifier? Just to full fill people has, I need to have also?

The product "aircooler honeywell cl25" assuming is the same as this http://www.amazon.com/Honeywell-CL25AE-Por...l/dp/B008UHXR1Y

Is a humidifier, and is for "hot dry climates, where the air humidity is low"

Ok, so if using the air cooler to blow myself when in fitting room and study room, just make sure window is open and let the air flow

For my study place i think should be ok since is upstair living room, open air

I not expected whole room to be cold like aircond, have a cold air.blow when my wife make up or when im surfing is enough , 2hour enough to build up humid?

A table fan is all you need

Yes split vs window type. The former has blower and compressor split whereas the latter is interlinked. I thought so too that you might still like the high ceiling. The volume above the ceiling needs not be cooled. What's more important is the air surrounding the room up to 8-9ft. That's where most occupants are and it's key that they feel the cooling.

If one AC place it on one side of the wall where it faces the kitchen. Here's where long throw blowers like Mitsubishi (Electric and Heavy Industries) and Samsung really comes to play. The long throw mode can reach the kitchen so long as the circulation path is not obstructed. Normally, installer would place it at 8-9ft high.

If two dedicated AC normally because room orientation and placement limitation, Sharp gull wing or Samsung triangle can consider. But Samsung needs 4 core wires vs the rest that needs 3.

Long throw only are good if you always clean the filter and set to the max.
Skip Samsung as far as possible, not that reliable compare to others.

Normally high humidity is not an issue if the temperature is cool like 27 degrees. Lower temp means wetter and most likely it beget mists as dew point is reached. 80-85% at 26-27 degrees, then it's pleasantly ok. But in a room that's already baking hot and it never goes down below 29 degrees is not healthy also. Have to consider one with the other.

Mostly, the surrounding environs come into play. Brick walls and glazed floor tiles normally has that coating that keeps moisture intrusion low or negligible. The excess humidity builds up and as temperature rises it feels very "kook". If the floor is marble (broken or tiled) and the wall uses venetian plaster (similar composition as Ipoh marble) then the excess moisture is wicked away. Even in hot afternoon outside, the house whose floor is marble and walls are using venetian plaster it will be surprisingly comfortable even at 30 degrees and 75% humidity.

To put it into context, humidity would not be an issue if we are surrounded with lots of overgrowth (trees) eg a house like the one in Sekeping Serendah. But in a concrete jungle, it all depends on what the dwelling type, floor and wall material's response to excess moisture and the surrounding. No doubt if a dwelling has lots of openings that it gets windy during the night, humidity is not an issue. The old kampung houses are best esp if they are surrounded by trees and raised on stilts. That's correct climate response and in Queensland, they old homes up til after WW2 are built like that. Louvered (Naco) windows are the best as it captures wind from any direction with up to 95% capture. Mosquito is an unwanted side effect but that's another story. Not to mention the deep set verendah/lanai which is missing here but now here that's a security liability/risk.

High rise properties different again because 1) it's easier to catch the wind at higher elevation and 2) the intrusion from ground heat that a landed property experiences is minimised except for penthouses. The raise on stilts part is why condo can easily capture wind hence cooler.

It's different story esp for landed. In my landed dwelling, that wasn't the case. The walls and roof baked my home kao kao. So how if I don't install roof insulation? Time the roof ceiling extractor fan to pull cool air in at 3am until 7am so that the house remains cool. Pull the air from the front inwards to the back so that the kitchen don't feel like an oven. This is one way for an existing dwelling to properly respond in this climate: Cross-ventilation and proper regular air exchange.

So why Ac works? Dehumidification. But the art and science is how much and how low in our climate? Actually not much. 26-27 degree ok already in day. 28 degree with 1 speed fan already ok in the night. Any lower is waste of electricity and unhelpful mis-adaption for our body as well as excess drying rate for the lungs of young chidren.

If you're in Klang Valley, check out jintex electronics.

My study area will have ceilling fan, just wan something cold air blow me when im surfing web and update some facebook pages, installing aircond is possible, just i wondering is that ceilling fan + air cooler is enough? I could save some money and electric bill too

Circulating air will be cheapest method, comparing heat transfer equipment, regardless of heating and cooling.

If I still living in Malaysia and never being send to work in ME, yes, you are right.
But nope, some of your statements are totally wrong.
Humidity and temperature are 2 separate things.
I can have high temperature but low humidity and I won't sweat.
I can have low temperature but high humidity and I sit in my room also I'll sweat.
Both humidity and temperature will yield a heat index and that's the factor to determine how "hot" is hot.
As said before, humidity in Malaysia are constant throughout the year, so it won't build up or go down much. Only temperature will be changed. High rise building are good heat collector.

Bro, yes if extrapolated that way. But in our context, here 28 degree at 80-85 is still quite uncomfortable and that's correct. Like you said not that low but still high humidity.

High rise building heat collector very perceptible at the penthouse or highest level and not so if any lower and in between. The mitigating factor is wind movement at that elevation.

Humidity in Malaysia varies from locale to locale but in urban dwelling esp inside landed homes the only constant factor is high humidity and high temperature without AC is uncomfortable. Unless one sleeps outside with mosquito netting different story. Normally windows closed because: 1) mosquitoes 2) noise intrusion from street but that's the side effect

Don't standardize KL landed property to other locations. I sleep with windows open and never have both of your said problem. Choose the right place to stay are more important than want to show off. Is very obvious you are the kind on showing off type.
I seldom eat meat now and mosquitoes don't like me. You want a sick lifestyle but does not means I need to follow you.
If a single high rise building in the middle, then yes, it will be good, but what if all rise together? You get nothing.

Bro, sorry if I come off that way but that's the truth in some parts of KL and PJ it's a urban heat island where I live or used to live. No joke. Some places need them and in some not too much of it required. I'm sharing what I have experienced but that doesn't mean any of our points is not valid. No one is asking anyone to follow anybody here. Don't cloud the issue. Peace ok?

KL and PJ are surrounded by buildings.
While in Seremban still surrounded by trees.
2 different cases, so your logic still fails
And the amount of waste gas also play a part.
That's why I won't getting rm2000-3000 extra a month but losing out my health and morale.
