any brand or model that you recommend?

3M only uses 2 filtration.. which brand has 3 stage filtration?

Ok, I do understand that Amway is MLM and all, but cmon... 

Many filters just filter out 99.99% of bacteria and viruses, there is no point to list them one by one (if they are truly certified that is). Same goes with VOC or pesticides or plastics. Most filters can filter out way, way more than 140 items. And I can guarantee Amway did not test all 140 elements, no one would do this. Everyone tests for the group of contaminants, not each one individually.

And why does Amway list fluoride as beneficial mineral? I mean, we can all read and make our own conclusions, but fluoride is a very controversial subject, where most people will consider it a poison. Just FIY, adding fluoride to drinking water is not allowed in Western Europe. In fact, very few countries add fluoride and among them are USA and Malaysia.

One more question, why UV? If they say that their filter can already filter out all bacteria, then what's UV for? Don't fall for marketing tricks, always ask yourself this questions.

I already explained why you need 3 separate stages, it's not for fun, it's the most practical approach. Yes, you can combine "20 in 1" filter, it's actually not hard to do. And it will actually filter all those 20 things... for first 10L of water that passes through. After that, it will be either clogged or it's performance will drop. And dirty little secret of the industry is that's how some of those filters receive their certifications....

Hi. Quick question. For water dispenser with hot and cold option, how does the hot water dispenser work? Does it continuously boil the water several times since it flows out direct from the hot water outlet?

My parent’s house is using Coway. However, my mum is recommending me to get an instant water heater instead of a hot/cold water dispenser due to the same concerns regarding the number of re-boiling that occurs if I do not consume the hot water often enough.

anyone use Bacfree here? Is this product good?

Been reading through the last 10 pages...

just a layman here.. any opinions of hot and cold dispenser of 3M, Coway, and Cuckoo ? 

Tempted to get the 3M HCD-2 because of the UV and NSF certification, but Coway and Cuckoo seems nicer with their maintenance programme.

The 3M system also seems to be the most expensive considering a 5 years life span including maintenance costs.

Honestly, at  4k for Espring, one is much better of with 3M dispenser +filter. It does not matter when eSpring can remove 100+ contaminants when all of them are VOCs, we have discussed it for many pages already.

BTW, not nearly everything is NSF certified by Coway, but some are.
