Been researching about water filter for household uses. Basically it all boils down to these three choices:
- Carbon filters
- UV light
Expert advices the combination of carbon filters and UV light. This retains good minerals compared to RO water which just removes everything.
Did some reading about RO water as well. Fish dies when put in a tank of RO water unless you fill aquarium with rocks, plants, etc. that restores minerals. So question is, why remove everything only to restore the goods one back? Carbon + UV seems to be the way to go.
Also, the certification to note should be from NSF 42, 53 and 55. NSF has a huge database that you can research on manufacturers and brands.
Searched NSF databases and the best one to get that offers carbon + UV combo in Malaysia seems to be the eSpring model from Amway.
