I would only recommend you to wash your fruit and vegetables only. I can't even find that having NSF 42 certified?

NSF/ANSI Standard 42: Drinking Water Treatment Units - Aesthetic Effects

NSF/ANSI Standard 42 establishes the minimum requirements for the certification of POU/POE filtration systems designed to reduce specific aesthetic or non-health-related contaminants (chlorine, taste, odor and particulates) that may be present in public or private drinking water.

The scope of NSF/ANSI 42 includes material safety, structural integrity and aesthetic, non-health-related contaminant reduction performance claims. The most common technology addressed by this standard is carbon filtration.

That is why I'm telling you, if u really intended to buy Panasonic those cheapo filter, I recommend u to wash fruit/vege only, not filter water then boil later and drink. Think twice, these kind of cheapo filter can't filter those Mercury or Lead etc...

In Malaysia, I wouldn't recommend any of my friends/families to buy any filter that don't come with at least NSF42, 53. So is up to you to decide since you are the one who drink the water, not me. In Singapore, you barely even find Chlorine in water.

Ps: Take this for example, buying a RM199 China Clone Smartphone, can I play 1080P video like the Galaxy Note 3?
