Drinking water filter is also called as water purifier or water purification system by some water filter companies. All these means that the filtered water can be consumed direct without boiling.

Why do we need a drinking water filter?

Some of us may just need it to filter sediments and chlorine and to remove undesirable smell. This is called aesthetic effect. If these are the main reasons, then you can easily get a water purifier that available in the market.

A system that certified by National Sanitation Foundation, NSF International (one of the world most trusted certification organization) for aesthetic effect is Standard 42.

However, if you are looking for a water purifier that can filter harmful chemicals, then you should look for Standard 53 NSF certification. This certification is far difficult to obtain and it needs to go through a series of tests conducted by the organisation. Not many brands that available in Malaysia are approved for this certification.
