Why ceramic? It is like the worst choice nowadays. But anyway, if you want ceramic there is only doulton.

i plan to use Doulton ceramic as a pre filter, then route to Panasonic countertop filter.

eventhough that panasonic filter have reasonable powdered activation carbon, but i think its not strong enough to filter rust and and sediments.

what do you think ?

i live in cyberjaya. so i dont have problem to trust the water treatment plant. its just the old pipes (rust/sediments/heavy metals) that im worried.

by the way, do you know what is the safest way to store water ? i always use cheap plastic bottles to put in fridge. but after reading about MICROPLASTICS im begin to afraid of it.

i made some research and found TRITAN plastics is better than other BPA-free container. but not sure if what they selling here is real tritan.

i dont understand, after so much filtering why do you still want to boil ?

as i understand it ceramic already can filter bacteria.

if you boil water containing heavy metals, it will only make it worst.

ok i found on fresca website :

Avoid ceramic filters. Some may not agree with us, but ceramic filters are evil. Claims that ceramic filters can stop bacteria are doubtful, however there is no doubt that bacteria enjoy growing inside ceramic layer. Think about ceramic filter as glorified (and way overpriced) melt blown sediment filter. There are more troubles than benefits.

i think saying ceramic filters EVIL is an exaggerated marketing ploy.

U did not install the filters under aseptic condition; i.e. u neither handle the filters with sterile gloves nor sterilize the housing / tubes each time u change filters. As a result, the filters and housing / pipes are contaminated from day one.  Moreover, the area around the kitchen sink is not sterile.

I am not a seller, just a satisfied user of ceramic for over 20+ years. It's perfect for cheapskate me, however YMMV. 
I don't understand why. Care to explain?

Boiling water contaminated with heavy metals is not recommended because it does not remove the metals; instead, it can make the problem worse. Heavy metals like lead, arsenic, mercury, and cadmium do not evaporate or break down at boiling temperatures. Instead, boiling can increase their concentration by evaporating water, leaving a higher proportion of heavy metals behind.

To remove heavy metals from water, filtration methods like activated carbon filters, reverse osmosis, or distillation are more effective.

Where did I claim that boiling will remove heavy metal? Indeed, boiling does increase the concentration in theory, but the question is how significant is the increase in normal boiling?

Please show me proof that activated carbon filters can remove heavy metal.

hello. why waste time and money to boil? if the water already have heavy metals, there is no point to boil. thats my point.

Not significant at all.

Average activated carbon in fact can reduce, but not remove heavy metals. However, there are modified versions for lead, arsenic, chromium, these can usually remove some specific metal.

yes but arsenic chromium and lead is very rare in malaysia.

do you have the statistics to show otherwise ?
