All these filters are just " Gimmick gadget "

some claim wow drink the plain water like got " a flavour feel very clean " actually u are drinking more toxic ....u never know the filter side got what also

next u also need to change the filter , NOT just oh I buy , install Forever use , no need maintenance.

You need to change the filter after certain period of usage.

THE BEST nature way still BOIL water ..simple as that.

Already touched on all these points earlier.

That is why you look for the NSF 42 and NSF 53 certifications. NSF 42 for material safety, NSF 53 for the contamination reduction testing.

And then go Amazon for the deals. For the dupont that i listed before, it's like $2 per month cost for a typical family for every 4 months change. Way cheaper than even a packet of chicken rice.

There is indeed a drawback for solid carbon blocks, they do breed bacteria after some months (that's why they advertise 3 to 6 months changes). This is regardless if the XXX gallons capacity has been hit or not. That is why the manufacturers lists it as say 500 gallons OR 6 mths whichever comes earlier.
If you are going to boilng the water after filtration (or hit 80 deg C, still ok), then definitely no issue.
