Does anyone know of an inexpensive but good water filtration system available here in Thailand ?

Perhaps you might want to explain more? What purpose? What type of source water? Where?

I want to use for drinking water. I am in Laem Mae Phim a little south of Rayong .We are on a well.

The cheapest type would be a micro pore type cermatic or plastic filter which removes most things. RO is more expensive and will also help improve taste as well as remove just about anything. UV filter after either of these would probably make water even safer. But without testing well water it is really just guesswork - and expect most people would rather pay for name brand bottled water for only drinking.

If you visit HomePro or other such place they will have dozens of different type systems - some getting very expensive.

I am in Bangkok so water is actually safe to drink but I have one of the below RO systems and believe it is one of the cheapest available and seems to work well.

I never believe in those UV system. Not when bacteria can accumulated inside the nozzle of the discharging faucet.

Best for me is to boil a kettle of filtered water to make coffee in the morning, and refill the bottle of drinking water in the refrigerator at noon.

If UV filter worked there would not be any bacteria to accumulate - flow of clean water would keep it clean. Then again, if your name is Howard Hughes, that might not be enough.

Just a slight correction to some posts a bit pedantic yes, but here goes .There is no such thing in water treatment as a UV filter. It is UV light at a specific bandwidth.

The most effective sterilizing range for UV is within the C bandwidth (UVC). This range - between 280nm and 200nm - is called the germicidal bandwidth. UVC has been used in hospitals for decades to disinfect the indoor air, surfaces and instruments in operating rooms. Many food and drug companies use UV fixtures with germicidal lamps to disinfect various types of products and their containers, water treatment works and even barbers shops

In water treatment the water passes over a germicidal lamp which in turn is encased in a quartz glass tube. One of the big problems with these home units is that people rarely clean the out side of the quartz tube, over a period of time the efficiency of the lamp is impaired as UV relies on good transmisity for good effect.

Always go for a home unit that has a UV lamp as it a really sure way of killing any bugs including crytospyridium the big nasty one..
