UV light is not a media to filter contaminants, it's use to deactivate bacteria & virus which are also contaminants. Contamination is the presence of an unwanted constituent, contaminant or impurity in a material, physical body, natural environment, workplace, etc Meeting the requirements of NSF & certified means the quality & performance of the filters is good. The most reputable 3rd party certification in the world currently is NSF, and also WQA. Certification can at least promise the effectiveness & reliability of filters as they are regulated & tested from time to time. Another thing to clear off is, tested accordance to NSF standard not equal to getting certified by NSF, it's 2 different things.
TDS (Total Dissolve Solid) test is only use to measure the present of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form. It's best to check for RO water whether the membranes are working well. It's not use to determine whether the water is safe from contaminants or not, because it can't read the present value of microorganisms.

Thanks bros for reply to my original post. I am undecided on which to change to - my requirement is to have pure filter and no Alkaline / RO. I read eSpring is actually alkaline water. 3M CTM-01 which costs a few hundree bucks - would it be a downgrade to my current Nesh?
eSpring is not alkaline water. It is pure filter water that only filter 140 contaminants and remains it mineral water.

Agree low TDS does not = to clean water.
However the test shown, all water filters are filtering the same contaminated water with high TDS reading of 1740. Hence, the filter with the lower reading shows that it is able to filter more of the contaminated water that is causing the high TDS value. Note : none of the system tested are RO filter. If RO, it would show reading below 10.
As explained, all 4 filters are certified with NSF 42 and 53, but why some with high TDS reading while some low. NSF only certified PASS and does not rank the filters, this is the problem with 100% relying NSF, this is what i want to point out. Like Culligan which other forumers mentioned has NSF and cost RM 400-500 then why buy AMWAY which cost RM 3k+ ? Is the RM 400 and the RM 3k filter equal in performance?
FYI, doing these videos are not ez, need to get the other brand filters, need to get a pump, need to connect the pipes, it leaks a few times, check and repair, air pump, getting the chemicals to create high TDS reading and etc etc. All effort (time and $$) put in also lose to those who created duplicate accounts, flood the thread which cause readers unable to get real info, keep on flaming me, reporting my posting. i would say more than 50% of the people commenting here are sellers but i am the only 1 who kena bcoz i only have 1 account and i sell a different brand. Hope admin can investigate and suspend the accounts

If ones is so good but it can't pass the test/not willing to be tested, it's still just claims by one party. As you said, different brand use different technology & filters capacity & quality, thus the difference of price. It's like NCAP 5* Volkswagen compare with NCAP 5* Toyota. By comparing eSpring with others, which filter is certified NSF 42 (aesthetic effect), 53 (health effects), 55 (UV microbiological treatments), 401 (Emerging Compounds/Incidental Contaminants) & p477 (Microcystins reduction) that is cheaper than it? What i can say is, you pay for the quality & reliability, if it's proven then you decide whether it is worth it or not. COWAY is certified NSF 42, 58, 401, p477, it cost between 3k-7k via monthly rental.
Your tests are great and takes a lot of effort to setup, this is good to show customer rather then just verbal claims. But honestly, it's still a simple DIY things that can't compared to those 3rd party certification testing. Look at NSF test laboratory below...
As a consumer, trusting & rely on NSF testing method certification or some home DIY test? It's your choice.
Let the moderator do the checking then. If your post is not violating the rules, why bother those that reported your post? Few of my posts reported before, i don't bother it at all The moderator will not take any action to remove any post that does not violate the rules.
Another important point is, by filtering/blocking bacteria & virus, can you promise there is no 2nd contamination will occurs or the bacteria & virus will not grow inside the filter? Best way to eliminate these are to destroying it's protein membrane which will kill it.

Lol i think u didnt get my point here. May be u keep on thinking i m trying to push my product and compare with other brands with NSF. As mentioned and asked, would u agree a RM 400 filter with NSF is equal to your AMWAY Espring which is over RM 3k+? The main point of the video is to show forumers different filters which pass NSF do not perform the same, there are some far better than others but all were CERTIFIED PASS only.
Extracted from one of the NSF Performance Report. This filter is able to achieve 97.6% reduction but NSF requirement to pass is only 50%. Hence, if cheap filter achieve 55% while the Expensive achieve 97.6% but both labeled as NSF CERTIFIED only, consumer would thought the cheap is as good as expensive one.
A simple test like this is already sufficient to show different filter with NSF have different performance result and they are not equal, hence that is why there are cheap filters and expensive filters (Eg: Cheap Filter Pa. Cheap filters pass NSF but does not = they are as good as Espring.
NOTE again, i dont sell Espring and Espring was not tested in this video, i bliv Espring would produce good results as well.. Just pointing out dont blindly just look at NSF. If got NSF = the product is not bad, then look at the filter technology, to compare which is a better product.
If sharing such thing also get also get my account suspended while other seller posting so many AMWAY stuff didnt get suspended, something is fishy then.

Wow, now i only realize RM300++ actually can get a water filter with NSF/ANSI 42 and 53. What is the difference between this and the 3M undersink water filter? undersink cartridge better?
Undersink save space

Yes, of course u still have to look into the spec sheet. By far NSF still is the most reliable party to be trusted by consumers over 60 years. They don't only certify water filter, they also certify cookware, sanitary products and etc.
I don't sell water filter for a living, not earning few hundreds to thousands, more of sharing fhe goods of it. Those that bought with my help get back all rebates that they suppose to receive, i don't sell it under my membership. Some that i share with even go to find their friends to get it.
Just report the post if u find it violate thw rules, seriously it doesn't bother me

Maybe you like to enlighten us how Aquaphor able to determine an effective lifespan of 8000L without NSF certification?
NSF certified products have their lifespan tested and determined by NSF. Aquaphor spec means nothing more than just a self claimed figure, which any Tom, Dick or Harry able write whatever they want on the website.
To be honest, if you have compared all NSF product data spec online, such self claimed figure of 8000L is out of the world. In fact, it sounds too good to be true. It beats all the other inventions by major manufacturers in the world. Perhaps 3M and Amway should fire their scientists straightaway, and find this Aquaphor employee immediately from Russia/Eastern Europe.
All filters have their own technology and claims. Some are good as they able to have proven methodology with facts. Some are just really mere verbal claims without any supporting documents. It's all up to us as consumer to make decision on which suite us best & which are reliable and within our own budget. Again, do more studies and checking then you should know which are best suite you.
