Mahdam, I guess you are talking about a household reverse osmosis water purifier and filter something like this:
I did consider installing one myself to filter the town's water supply. Primarily I wanted it for drinking water. I assumed that they (the filters) do the job for which they are intended although the filters need to be changed at specified intervals to ensure the quality. In the end I decided against it and bought a cold water dispenser that has the 20 litre bottle on top. The main reason for rejecting the idea was the thought of endlessly filling 1 litre bottles to store in the refrigerator to get cold water to drink. In our house that would mean some 4 or 5 litre bottles each day. It would also take up valuable room in the fridge that could be better used for other items. Cost was not a factor that I considered.
The cold water dispenser is similar to the one in the picture but without the hot water supply for safety reasons (young children in the house). I buy the more expensive FAR THAI Water and have never suffered any stomach upsets with this water supply. This gives a constant supply of cold water 24 hours each day and the bottle only needs changing once every 3/4 days. Subsequently, when I analysed operating costs I found this solution to be very cost effective. Water supply by FAR THAI runs to 5 x 20 litre bottles every 2 weeks. Thats 10 bottles per month, 120 bottles per year and, at 20 Baht/bottle, the total cost is 2,400 Baht/year. The water dispenser was some 3,000 Baht and the electrical operating cost is minimal.
