Go for UV. All these filter for drinking is of no use without UV you still need to boil. My filter has 2 UVs. One inside storage tank on/off for a few seconds every now and then itself and on when filling water. And the other at the outlet as you dispense water the UV comes on so that all the dispense water are again sterilise just before you drink. Almost fullproof. What is not full proof is your drinking glass, lol.

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.

In this case, I should avoid UV. Maybe NESH will do

Dont throw it away dude, is antique! You send to me, I do the recycle for you!

Yes, UV lamp cannot last long and its efficiency goes down with time and even if it is not burned you have to change it every 12 months.

But mine is different. It can last many years, 5 to 10 years to change. Why? Some filter UVs are on all the time and its efficiency or life span is one year. Whereas mine, as mentioned earlier, comes on and off every one hour just for few seconds and come on when the tank is filling water and on when dispensing water and will go off once water flow is stoped. As such it lasts you many years, save you money and maintain its efficiency. And the UV lamp is made in USA Philips.

This filter system is very superior in design and technology. But you will be put off by its price. But if you want the best this is the best drinking dispensing water system in the world now come with hot and cold. All components are FDA approved for USA market. Even the tube, the tank, the filter, etc each and every components and parts are FDA approved not just the whole unit.

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.

i am about to buy a NESH indoor and outdoor water system today.
but decided to give my last survey on the product and i read thru this whole thread.

the conclusion i got is:
NESH doesn't have certification by NFC

- i checked thru nesh website and they claimed this : http://www.nesh.com.my/en/joomla-overview/...ed-by-nesh.html
Does it mean they are NSF certified now? (i don't know nuts about NSF n such)

- NESH claimed that they are WQA recognized, but i went to wqa.org to check and their product is not recognize... just they are a manufacturer in malaysia registered as member in WQA.
http://www.wqa.org/sitelogic.cfm?varCenter...esttimeout=2500
Does this mean anything?

* i've tested their product and i love it.
* their product explanation sounds logical and convincing too.

What's your thought guys?
Thanks in advance for ur advises and responses.

my concern is are these certs really that important?

comparing to the actual quality of product (water) VS with certs+paper but quality not as up to it!
i am using Amway right now, but i don't like it... water got some sort of taste the after each change of filter... have to put the water running for 12 hours before the weird taste goes away. maintaining an Amway is expensive too, personally not worth my money spent.

I like to read the so call 3 oxygen atoms. Maybe my physic and chemist I learn was wrong. So easy to get atom.

Amway good but their salesman are lazy... Sothey lose out.. Love their uv but so expensive n salesman is inexperience. If it wasnt for the current renovation expenditure.......

Just learn something new today, wanna share it with u guys. THere are many stainless steel sand filters in the market, some cheap and some exp. Cheaper ones are using stainless steel tank imported from china. The seller will say it is 304 grade stainless steel but it could b some part of it is 304 or it is not really 304.

For perfect steel brand, here is how to differentiate CHina or Malaysia 1. As u can see, the China tank on the left has rusted

Ozak, you are right. So I survey here survey there, check this that then cut this for that. Then certain thing buy mid range instead of high end. So I'm still waiting to see which air con n fridge is more value for money right now n if I can use 2.5 aircon piping for 2hp air con so that I can upgrade.

If i buy 3m do I need to modify anything if I wanna change to espring or equivalent? Piping, tap n such?

Use for nearly 8 months now. Still Healthy ;-)  I am not really concern of the minor difference. Maybe yes if I am in India. Oh well who know if syabas want to kill everyone before they get killed.

Many forumers PM me asking about when do we replace the cartridge for 3M.

AP902 (outdoor) - Can filter upto 370,000 litres of water (averagely 1-1.5 year depending on usage and water quality)

APDWS1000 (indoor) - Recommended to change every year.

u try put those pure water into aquarium and see how the fish next few days

I notice this PVC valve after long exposure on the sun, it will become sensative to pressure change. When you off the main incoming, the presure may have switch high from incoming to low. And that cause the PVC valve leak. The PVC valve on my 3M filter had this problem, it happen right after Sybas water distruption (after 1 year of usage), same for my mom house.

I end up change the PVC vavle to Brass, it cost me around 20+ each, and i need 3. Still no time change my mom units, but temporary I managed to fix it by just turn on, off the valve few time.
