None of the water filters described here will provide clean bacteria free drinking water other than the one described by Kopkei. All water must be treated with either chlorine, UV light, Ozone or by boiling before drinking to destroy bacteria and other microorganisms. The filters described here will only remove particulate/chemical/organic/inorganic substances.

Well water possibly but for city water? I prefer the more moderate, "must be treated with either chlorine, UV light, Ozone or by boiling before drinking if bacteria and other microorganisms are known to be present." Unless one has an impaired immunity for one reason or another, your digestive system should be able to handle it. However, water for infants with undeveloped immune systems always needs to be boiled first.

I used to refill my own 15 liter water bottles for the water cooler with city water from the simple, 3-part faucet-type filter. Did that for the best part of 4 years and nobody got sick. I did always drop half a chlorine tab in the empty bottle before filling it. A whole tablet and it tasted like the swimming pool.

The Udon city water system is a low pressure system which will more likely draw in contaminates from the area it's traveling through than a high pressure system which is used in developed countries. Considering the routing of the lines through the grey water system running along the roads and the high number of leaks (repairs by a rubber inner tube) i would not be so confident the water is drinkable. BTW these same grey water conduits also carry off the overflow from untreated septic tanks. To make matters even more difficult I have no idea how the city treats the water supply. We live in Nong Samrong on the north side of the ring rd and use city water for showering. However, we also have a Waterco Multiport Valve whole house filter filled with Zeolyte resin installed before the storage tanks to remove particulate matter. However, it will not sanitize the water. We have an under the sink water purification system (charcoal block, resin, ceramic & UV light) installed in the kitchen to provide drinking water and water to wash veggies etc.

Thanks FD, just going back to my original post, the water from my well at the moment is only to be used for bathing and washing clothes/dishes etc and no intention of drinking, I wanted to get rid of the film that collects on the surface after an hour two, apart form that the water looks clean and does not smell, I think Tamada's set up will be a cost effective solution to my prob, as suggested, maybe half a Chlorine Tab would kill off any bugs, I buy in treated water for drinking and washing food at the moment.
It's weird how the well location in the same area can affect the quality of water, I have another well about 200 metres away which I have used for bathing for several years and never had any issues, no filters of any kind, just pumped straight into the house.

The advantage of starting with the basic 3-part, distributed system like mine is the option to expand it at relatively low cost if that is required. In BRD's scenario, he may find the basic PP and pleated paper combination on primary and secondary filters sorts out his surface film issue. If not, another filter housing can be daisy-chained on the primary and another type of filter element installed. If at a later date, the well water starts to smell, another housing can be added or the type of filter element in an existing housing can be changed to address this.

Although I added the half-tab of chlorine to the water bottles before, it was only while doing some recent research triggered by this thread that I learned that dropping a whole tab in the secondary filter housing each time you replace can assist in sanitizing the pipework. I might try that when I get home but will do it on a week day when everyone has showered and be out of the house.Then I can run the showers and unfiltered faucets to avoid complaints about the smell or possibly stinging eyes.

some economic advice about the small household filters with UV lamp...
i have never looked close at my 4 way + uv = 5 filter until recently a friend asked my advice , the cheapest you can find them now online ,not in any shop (prices from 4.900 to 7.500 and more), is 2.190 baht, so what i did now is ordered a 5 way filter not with uv sterilizer lamp ,same brand as the one i have now ,for 999 baht (you can buy other brand starting around 750) , this filter is exact the same as mine except one filter element more but no UV , this UV i ordered separate for the price of 790 baht , and i added this to the new 5 way filter , so now i have a 5 way filter + UV = 6 , one filter element more as before for the price of 1.800 baht , what you do need to look at is that some filters come with a resin filter element(softener) , as we use it on city water i replaced this one with an activated carbon (granules) cartridge , not activated carbon block one ... , btw replacement filters ,also never buy them at the shop (490 baht/piece) ,
normal prices for replacement cartridges are about 100 baht for resin, 100 baht activated carbon ,ceramic 140 baht,
activated granules carbon 89 baht ,PP element (if you have ,i use ceramic) 40 baht ....
placement with us under the kitchen sink ...

Hey kopkei, this is a system I’m looking at, I’m getting cheesed off of running out of water and having to used bottled, plus it’s not very good to keep using so much plastic. The only real issue I have is that they seem to come supplied with separate taps, can they be used via a regular sink tap?

Basically needs a half-inch to quarter-inch male-to-male adapter.

I have used a couple of these to connect the standard 1/4" line outlet of water filters to 1/2" domestic pipework. Try at the water filter aisle at Amorn under the food court end of the Phosri Big C. I have also seen them on the water filter shelves at various times around the corner at Thai Watsadu. Otherwise...

These guys also make very high quality filter systems, handling water from slightly dirty municipal supplied to river/stream water with sticks in it; but I don't know if or how one might get them to Thailand. I put such a system in a condo building where I lived, and it worked incredibly well.

normally they always install the extra faucet ,because the pressure from the water after the filter is maybe to low to go trough the bigger pipes , it is not so difficult to install ,with us i did this...

this one has 5 filter elements + uv https://shopee.co.th/%E0%B9%80%E0%B8%84 ... 1032722878
all needed to install is in the box...the only thing you need to do (optional) is change the pp element by a ceramic one that filters better... ;)

I have a three element filter that I used to filter rain water for cooking and drinking. The final element is a ceramic filter. Even coming out of a water pump it takes maybe 30 seconds to fill a one liter bottle. If you want to filter water for the entire house, don't waste your money on this type of filter system.
