Highly recommend eSpring.
Reason being is not just about number of filters it has or number of layers filter it has.
Its because eSpring has certification of number of contaminants it can filter, thats the main point right?

Even if you have 1 or 10 or 50 layers of filters, but if you dont really know what it can filter, whats the point?
Not just generally "bacteria/virus/heavy metal".
eSpring has a list of 164 contaminants it can filter.

Thanks

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....

Its not about Amway or not.
Read the news below, and how many indoor water filter can really 100% filter this?

Why UV? eSpring produce mineral water, means the filter size is not as small as RO water whereby everything is filtered off.
Therefore the UV is to kill them.

Just curious, are you staying in Malaysia currently?
Cheers =)

It's first time in my life I see someone backwashing melt blown filter. Not a good idea at all. You wash melt blown once and it's performance decreases by a lot. Melt blowns are never meant for backwash or any kind of wash, they're cheap and should be replaced regularly (like every 3-6 months!)

This is in fact 4.5" by 10" housing, slightly weird design so that you can only use their filter (my guess, maybe any filter will fit).

You can just get a standard 4.5" by 10" housing and install high quality pleated polyester in it. It will be just a little bit more expensive, but your flow will be much better, it will last longer and it will not degrade significantly for whole 2 years. But even pleated polyester, just take it our and quickly wash, no need to backwash.

Yes, this size might be too small for a full house, but also feasible if you don't use much water.

Price breakdown (approximate):

1. Housing with pressure release valve - 250RM

2. Quality pleated polyester 5 micron - 150RM (NSF, US made, washable, 2-3 years service life)

3. If you absolutely want melt blown filter for some weird reason, then good NSF one will cost roughly 50RM. But no way it can last 2 years. Change at least every 6 month or even more often depending on water quality.
So yes, all in all this is what I described before, just smaller and uses melt blown for some reason. For "whole house" solutions always use pleated polyester, for drinking water filters can use melt blown if change often.
Now, when they tell you ("they" including me) "it will last 3 months, 6 months etc. These are just AVERAGE numbers. It may last 1 month or 3 years depending on how bad is your water and how much of it you use. So how to determine???

The ONLY way is to install pressure gauges before and after the filter. So with new filter, the drop in pressure will be say 3 psi. 3 months after, the drop becomes 10, at 13-15 it's time to change (or wash in case of pleated polyester), means your filter is clogged. You can buy cheapest gauges, you don't care how accurate, only care to see difference in readings.

Pressure gauge is the industrial way of monitoring pressure drop for filters, strainers, pipes etc. Technically correct . But layman will only appreciate indicators and schedule. Layman should learn more so not to fallen to sales talks. For domestic use not sure easily available. Need to check around major hardware shops.

All UF or sub-micron filters produce mineral water. Any (assuming good quality of course) sub-micron filter will remove 99.99% of bacteria. Therefore there must be no need for UV. And yes, good sub-micron (UF, electro-adhesion etc) filters with quality carbon block would handle that organic compound described in the article. What wouldn't tackle it is something like a filter presented few pages up, simple sediment (only) by 3M and GE and the backwash one.

In fact, UV very often used in RO systems, but for a totally different reason, because water is sitting in the tank where it is exposed to bacteria.
In case of Amway, there are 2 options: either UV is totally redundant and is there to make filter more expensive, or the filter itself is not very effective and therefore there is UV version that's more effective.

No offense, but water filter from MLM company is not such a good idea. Again, this is just my opinion. I'm not saying it's bad, maybe it's ok. I'm just suggesting that there are better systems with lower maintenance cost and lower initial investments.

You may need check with your neighbor do they have similar issue? If have probably need ask PBA to check d.

Full list of technical information on method use for testing, test results, test parameters & so on.
It's claims also certified by NSF, if they were just talk siok, NSF would have removed the certification just like Diamond.
The filter can't filter bacteria and virus, the UV do the jobs by deactivating the pathogens.
Do some research at least...

Good sharing. eSpring lists out all 140 contaminants just to prove to consumers that the filter really can filter all those 140 contaminants. As other said no ppl will really list out all the contaminants they can filter or no ppl will care how much contaminants the filter can filter out. Just because most of the filter claims they certificate by which third party but sometimes it is not really. If they also list out the contaminants but failed to do so mayb they will bare the risk so they wont do this. Anyone can sue eSpring or NSF can just remove the certification if their claims are not true, it prove they deserved it.

Filter cannot filter out bacteria and virus no matter which type of filter, so the UV light take and important part of it. Knows that not everyone care about it, all is based on personal requirements and needed. Different ppl have different needed and willing to spend just like someone willing to spend for a BMW but someone just satisfied of their Myvi, its same thing.  



The water filter not only stop at current stage, the research keep on going, they deserved it.

sry eSpring to expensive for my budget. I dont like MyVi but i rather choose other model. instead of paying AmWay agent the commision same like Diamond and others Coway or Cocoo
product.

I'd just like to point out that in this industry, there is no magic. Industry is pretty stagnant, so there's only evolution here and no revolution.

A comparison of Myvi and BMW doesn't apply to water filters because then everyone would choose Rolls Royce - reverse osmosis, it filters out pretty much everything.

Don't look at the brand, brand in this business means nothing. You need to know what your filter does and what it's made of and where it is made. And while NSF is good, always remember that NSF is certification system, not quality control system. NSF doesn't tell you how long will filter actually perform at these levels or if your batch is not leaching plastics and chemicals in your water.
