It was a bad choice, and the Ozone is just an "another" marketing gimmicks which is no real scientific proven, and no NSF certified.

Seriously, I just received the next month offer from my upline last night, buy eSpring next month get one 32 inch Philips 720P LED TV PWP RM299, if I were you, I die hard wait for next month offer. #confirmsure

eSpring is the world’s No. 1 selling brand of home water treatment systems. However, whether it suits your requirement or not depends on you.

Coway is RO water which is demineralised water. WHO did a report on the health risks from drinking demineralised water. So it is not recommended to drink RO water.

NSF certification certifies what the water filters can filter. It is proof that the claims from the manufacturer on what the water filter can filter is true. It also shows what contaminants can be filtered. That is why all water filters want to be certified by NSF, but not all can.

eSpring has 4 NSF standards (42, 53, 55 and 401). You can check it on NSF website.

Espring filtered about 140 types of harmful contaminants.

Coway only tested by NSF to filter around 10 contaminants.

Coway= RO water....mild acidic.

Yup, hot and cold water is convenient, then you if you want a hot and cold water, really no point to pay RM3500.

ESpring actually is the golden standard among all water filter, if you looking for equivalent quality and performance of it, mostly only available in US or Europe countries.

The importance of NSF certification, I believe some above already explained to you. Simply Google for NSF Wikipedia, more detail are there.

Like one of above said very true, if you have a healthy budget to spend on the indoor water filter, why consider not consider a better brand with better quality and as well better long term usage. A OEM brand RO water purifier with condenser could costs less than rm1k.

I dunno if its world no.1 or not, but with NSF 42, 53 and 55 (UV)..i dunno what is NSF 401.. its very complete package in the sense it covers almost everything. Previously there was a Philips water filter that had 42, 53 and 55 as well.. and it was half the price of the eSpring, but it is no longer sold here... of course it would be better choice over eSpring due to the price.

I am not aware of any other water filters locally that is certified NSF 42, 53 and 55.

RO water is not suitable for human consumption as proven by WHO.

Bro..Amway is MLM.. you ask...sure many fanboys and downline come support their product 9 9 lor. But if that's the kinda budget you wanna spend...better buy eSpring than Diamond lah..Diamond can throw longkang.

As for Coway, don't bother, most of it no NSF. Some don't even have specification.
