That is why I go for an indoor drinking water filter that has a built in flow meter. Take the guess work out of the equation.

Alphamax can not filter the dissolved toxic chemicals nor many bacteria.

off topic.
If BN did wrong, I never defend them
If PR did wrong, I voice it also.

In theory, yes. But in practice, you never know. That is also the case with public water supplies in Western country when there had been cases of public water treatment breaking down and people dying because of it.

AFAIK, all public water treatments do 2 things only:
1. Remove insoluble stuff like dirt and sand etc. Same as your Back Wash filter.
2. Kill bacterias and viruses using Chlorine. Back Wash filter can not remove some of the smallest bacteria and all viruses.


If you don't want to take chance, my suggestion is:
1. Get a charcoal filter that will filter off dissolved chemical, some can cause cancer. No public water removes these. It will also removes the bacteria killing Chlorine so these filtered water must not be kept too long.
2. Get a UV light to sterilize any 'too-small-to-filtered-off' bacteria and virus. So no need for further boiling.

Just make sure you buy quality filters that are certified by NSF etc and conform to Standard 52(?) and for UV lights, Standard 55(?)

All mechanical filters like your 3M can not filter off the smallest bacteria and almost all the viruses. These are too small to be filtered. They can only be removed by Chlorine or boiling or UV light sterilization. Hopefully all those nasty things had been killed off by the Chlorine before you removed the Chlorine.

When you replace them, make sure you don't use your hand to touch the tube body itself and leave finger print.

It should last 12 months.

Is that the 2nd model, the one before the present ones?

IMO, though expensive, Amway's is one of the best based on specification. Philips got a good one but could never find it in the market and it's a lot cheaper.

I would like to know which filter water that has fulfilled the following standards at cheaper price than Amway.
1. Fulfill NSF Standard 52. Removal of dissolved chemicals etc.
2. Kill bacteria and virus so no need boiling. Something similar to NSF Standard 53.

I have tried looking for alternative but couldn't find one.

19L tank. Are these certified? Some bottled water are mere tap water.

Charcoal filter. Can remove dissolved chemical but these need changing. I only trust those that had been certified by NSF. And I think those certified ones all expensive like Amway.

Boiling. I hated this. Only easily found viable option is Amway.

I have looked high and low to replace the Amway but no luck. They are still the best and most importantly, easily available. Philips has an almost equally good ones at half price but nowhere to be found.

I think you are confusing Amway system with R.O. membrane system. Only Distilled and R.O. system will remove the minerals in the water and best be avoided. Amway and others don't.

so how much is the price per liter of those bottled water delivered to your office?

That is 53 sen per liter. Super expensive.

Amway's filter is rated for about 5000 liters at about RM650 thereabout. That translate to only 13 sen per liter. May be just go trade in your old Amway for the new ones. Cheaper, certified cleaner water, less hassle on delivery. My 2 sen.

How long it will last and how well it can filter are 2 different thing. IMO, the later is more important than durability.

Philips used to have one in Malaysia. Manufactured in India. Very cheap. But it does have the necessary NSF 42/53 standard so definitely worth a look. I didn't because I couldn't find any dealer having it so getting replacement filters will be a problem. In fact, of the few I contacted, they don't even know what I am talking about

Like I said earlier, just make sure your filter has NSF or WQA certification 42/53. If they don't, just walk away.

Technically, Diamond is a joke before.

But I notice they now say theirs have NSF 42/53. If they do have them, should be OK now.

Are they using Reverse Osmosis? If yes, you don't know what you are talking.

Ha. Some filter manufacturer keeps peppering their brochure with the word "NSF". But no details which NSF Standard they adhere to.


Filter A : The world's best impregnated ceramic filter, which has been awarded NSF Certification, thoroughly removes bacteria and impurities like dirt, silt and rust.


Filter B : NSF certified activated carbon removes unpleasant odours and colours, while natural mineral stones regulate mineral content.


Filter C : Composed of NSF certified Grade A activated carbon and a KDF metal ion converter (meeting the standards stipulated by the FDA and EPA of the United States), this filter completely removes heavy metals, chlorine, and other chemical contaminants.

Filter D : The CE2000PI Energy Conversion technology of Japan effectively breaks water molecules into the smallest possible clusters; making it easier for our body to absorb. It also increases the dissolved oxygen content in the water.


Filter E : A high-tech ID2 energy stabilizer with far infrared technology stabilizes energy in the water to keep water molecule clusters at the smallest size for a prolonged period of time.


Filter F : High-density NSF certified activated carbon combined with natural magnetic stones help balance the water to a mild alkaline level and increase the number of calcium ions to further enhance health.

This is very common with Malaysian. Very often, they will say a thing is good or bad. But couldn't give you the reasons for saying that.

So we have people saying Reverse Osmosis is good but couldn't tell you what good or bad about it.

We have people saying Lynas is nuclear reactor but couldn't give you reason for saying that except the word "radiation".

Yes, World Health Organization has a circular saying "de-mineralized" water like those from distillation and Reverse Osmosis "is not the best choice for drinking".

Too much work. Get a proper water filter system, turn the tap, and we get clean water to drink.
