Just like to share what i found and had bought for home water filter system. after doing some intensive research over 2 weeks. i decide for APEC 5 stage reverse osmosis under sink water filter. i was torn between using expresswater or APEC. But from reviews both in amazon and outside, it seemed APEC is the preferred model. but expresswater comes cheaper and with extra water filter ! I have left the UV light option out as i think ours is considered city water that is already well treated and besides i do not want complication of getting the wiring for uv light and if anything wrong i gotta fix the uv. however, since i cannot find a company here selling, i will have to diy install. i manage to get a plumber who say he can install but regarding the kitchen top faucet, he need my kitchen contractor to install the faucet, the rest he can do. so YES! i bought from amazon and ship via my package forwarder.
