Do you think AI could explain such a concept? Unfortunately, it likely cannot. Feel free to give it a try yourself if you can.

While certain individuals might have feelings about it, the matter is straightforward. A friend of mine who worked in the wastewater and sewerage management industry shared a wealth of valuable information with me, which I also incorporate into my understanding. Spending over RM500 or even thousands on those things feels pretty "meh".

Well, the reason I asked is because it is a lot of generic information and a lot of rather questionable info. Like 3M is actually made in China or Mexico last time I checked, only the head is sometimes US made. Aquasana is 100% China, but represented as USA, while you also mention that country of manufacturing is important. LGA-TUV and Pascal institute certs that are very strong European certs are not mentioned, yet Chinese certs are brought up. But yes, there is some useful info too. Sorry if I offended you with the AI statement

Found my answer

LG is bad in their service, which every time i need to contact them before they even send me the filter even it is more than 6 months.

It's totally okay to be curious.

In our global world, products like water purifiers are often made from parts that come from all over the world. A filter cartridge may be assembled in one country, but the carbon inside may come from Sri Lanka or Thailand. That's why we often see companies talk about using "NSF-certified materials" instead of just saying Made in "ABC". And it's not uncommon for a brand from one country to use a filter made in another.

I've always suggested starting with a "Trusted Brand" for safety and peace of mind, especially in case something unexpected happens. But if you prefer generic products, that's your choice. It's a free market anyway! My main advice is to always ask for lab reports to review the performance. This is how you really know what a filter can remove and that you're getting what you pay for. It's like buying vitamins, you want to know they actually work. To really know if vitamins are working, a lab test can measure nutrient levels to confirm if vitamins are effective. This scientific feedback confirms that the supplement is making a difference. Without such testing, you could be taking something ineffective or even unsafe, much like using a water purifier that may not purify as it claims without proof from lab testing.

You brought up a good point about European certifications like "LGA-tested". To be honest, I'm not sure how many European purifiers we see here, or how many non-European ones really push those specific certifications. My gut feeling (and I could be wrong) is that these certificates are more useful in Europe itself, not necessarily here in Asia.

Why do I come up with the idea of Chinese certifications? Because many unbranded products often claim great performance based on them. What happens is that these companies buy generic parts (often from China) and then put them into their own products. So, the performance claims are really just from the original Chinese manufacturer. This situation is similar to claims of “Made in Korea”, where the brand may originate from Korea, but key parts or manufacturing come from elsewhere. It's similar to supplements that may be FDA approved but not locally certified. Just because a component doesn't have a local stamp of approval doesn't mean it's unsafe, so we don't have to over-analyze every single claim. However, everyone has their own belief, so I also mentioned in my sharing that "what matters most is that the product is certified by a trusted and reputable organization".

By the way, I also made some small updates to my sharing from two days ago.

Oh sure, if you’ve got deep pockets, just set up your own company.
1. Partner with an OEM in China producing NSF-certified materials.
2. Buy their raw parts.
3. Assemble everything in Malaysia.
4. Get that ISO 9001 certification for some extra shine.
5. Add the LGA Tested Quality mark for extra assurance.
6. Secure FDA approval to tick international boxes.
7. Slap on a fancy brand name like "HESTATI".
8. Then send it over to JAKIM for HALAL certification.

Voilà — HESTATI is proudly “Made in Malaysia”. Easy, right?

They are all not great in terms of service, it mostly depends on the rep/person than the company itself. Coway is also horrible when it comes to service.

End up getting Panasonic Water Purifier TK-CS500-WMA, water no weird taste phew

recently since last year Dec, i use since 2022 ok that time
on time delivery

last month i waited more than 5 weeks
and then i use the msg to ceo in lg site, same day someone from lg call me
next day terus send out

That’s why I said need to manually call them which is not acceptable.

Please note that water filters are now subject to 5% SST. Our new shipment already got affected by it. So the prices will go up accordingly for most sellers, not something that can be avoided. Also, Shopee/Lazada are also raising their fees, but are compensating it with vouchers. Actually a weird move, cause they are now losing more money than what the collect from fees.

Hope I'm not too late to suggest.
Usually the external water filter is after your water meter. If can see the meter, then you may not need to hack the wall to locate to incoming water.

For external filter you can shop for 3000L or bigger 6000L UF filters.

Depending on your incoming water quality, these can last you ~5yr before the internal membrane needs to be replaced.

As these UF filters needs to be back flushed regularly, most customers will use the back flush water to wash their vehicles, wash the yard or water the plants.

Don't install the sand type cos I have encountered many problems with the particles getting into the internal plumbing.

He is in a condo. Most probably can't see the water meter at all, it is in a separate room and most condos will require hacking. Also, for most cases, backwashing in a condo is a hassle

Actually the water meter is accessible from the meter room located near the lift of my floor. But management do not allow the install of water filter at the meter room which makes sense, so the only point of entry to install is inside my own unit after the main incoming stopcock. And yes, that will require hacking unfortunately. Thanks for the suggestion though.

My uncle is looking for an easy maintenance, self service indoor water filter.. Doesn't like to rely on ppl to maintain it so he wants to do it himself..
Any1 can appoint me on the right direction pls?
Thanks in advance yea

LG has self-service plan, can learn more at the LG thread https://forum.lowyat.net/topic/5445954

i think this is the good thing about signing up 7 years contract, becos monthly subscription is fixed for 7 years with all the filters including as well as 7 years of warranty and each year free 1 time of relocation.

Yea even LG also raised prices

would like to clarfiy, the filtered water can drink directly for this model?

Yes. I drank directly and so far no stomach ache

Yeah, no choice really, no way around it...
