I am definitely of the category of people who prefer discreet fans. In fact, I would prefer no fans at all but who am I kidding, we live in the sweltering tropics and air-conditioned rooms are very expensive.
Generally, my preference in fans is that they be as plain and streamline as possible, without being hokey. I also detest any that have strings or balled cables dangling from the lights, it reminds me vaguely of latrines. I also draw the line at ceiling fans with lights, for some reason, I really do think its just beyond tacky and quite an assault of one's aesthetics. Ok, I have seen a Few, very Few good examples of that, (and these are usually in theme restaurants) but generally, I hate hate that the lights come in these frosted blue-bell shapes! Yuck!
In the end, I discovered that there really aren't many fans that one can choose from in Singapore, KDK, Elmark and Fanco pretty much have a strangle hold on the market and from what I can tell, Fanco is a store in-house brand. In the midst of discovering this and exploring Balestier of course, I learnt more than I do now about both lights and fans.

We are probably going to wind up with the basic 3-blade white KDK model, which can be had for a very reasonable $85 (comes with a 3 speed wall regulator) or the more upmarket 4-blade model with remote control for $185 (also in white, though the picture shown is in metallic).

I did though, find that there's lots of research that can be done about the health advantages to having proper ventilation and encouraging air movement. It's really interesting and the distributor of KDK fans in Singapore has a very good website about just that.
1) How does ventilation works?
The general concept of ventilation is all about moving air from outside of the building to the inside. Using ventilation fan, the fan draws the air out of the building and air natural replaces itself through spaces. Usually ventilation is useful in places where air is unable to replace itself naturally or in areas where air are stagnant.
Except as you can see, they wrote "How does ventilation works?". Yes, that is generally the kind of impression I have of people who install fans, too.
The second page on "Types of Ventilation Fans" is much better, though arguably no prettier.
There are mainly few types of ventilation for your home: Window Mount or Ceiling Mount. As the name suggest, they are to be each mounted differently on window, wall as well as ceiling and they will only achieve optimal performance when mounted on the recommended place.

1) Window Mount Ventilation
Window mount ventilation is usually used for home as well as small spaces whereby the ventilation fan mounted on a piece of material such as glass, wood or plastic. A rounded hole is cut in the middle of the mounting material and the fan is mounted on it. The most common method of installing the fan would be cutting a hole in the middle of the window pane and mounting it up directly. However HDB regulations states that residents are not to do any changes or mount up anything to the window without submitting applications to the authorities. Therefore, the only method to mount up the fan onto the window would be submit a plan which includes the details of the ventilation fan to be mounted on the window to the board.
2) Ceiling Mount Ventilation
Ceiling mount ventilation fan is usually fixed up in area such as office, shopping malls and home, where users have the option of fixing up the fan to the false ceiling. However, for such ventilation system to work, a ducting system needs to be in place to fix up the ventilation fan as the ceiling ventilator comes with a duct plug where air will be exhausted. A duct will guide the air out of the building and such ventilation system is usually recommend to areas who needs ventilation to different sectors over a large area.
Then I found, to my amusement, that there is a Singaporean blog devoted to fans. This is the website. http://singapore-fan.blogspot.com/


I've found his work very helpful, for example, the matrix of how long your blades should be, depending on the size of your room and his photos of ridiculous fans, well....ridiculous.
