I was told they were based in Malaysia as labor are cheaper and Malaysia is a bigger market compared to Singapore,almost 90% of the houses there needs water filters, so logical? no? They are tested with PSB singapore and Sirim malaysia for the quality with certification, so no worries. a normal water alkaline water system is relatively cheap to manufacture. do you know the cost is for per set? I don think any company will fool around with things that goes into the mouth, other than china factories :0 no worries everyone is entitled to their opinion, i am sure u didnt know that wall paper in Malaysia is also almost 50-60% of what are selling here some ppl like to pay extra and some like to pay near to value so different stroke for different ppl... peace
