May I know which seller are selling authentic matrikx cto in shopee and lazada! ?

Hi where to get the original omnipure or matrikx cto?

I feel we need better quality water, I feel the different when my kids drink cuckoo water they always got sick, but when they got to another family home they drink LG, SK Magic they are okay

Hmmm, this is really strange. I would investigate why this is happening. You are getting municipal water? Could the tank be dirty and infected?

Just curious, what kind of discomfort your kids facing?

Cough, fever

In theory, this shouldn't happen, either they missed their servicing schedule or the water tank is contaminated during servicing

not sure why you think it was the water problem. Fever is good because body is raising the temperature to fight bacteria/viruses. Cough sounds like another respiratory issues. Why not explore the problem in your kids bedroom (or your room) such as air-con, air humidity, air quality, etc?

Yes, this is my point as well, must investigate. However, it could also be if the tank is seriously contaminated. I remember I was in Nicaragua and bought bottled water, huge one, I think 10L. Had the same symptoms and was drinking more of water (cause they say must drink water, right?). Until I finally notice literal dirt inside the bottle.

So I would check the tank first and then everything else. If the tank is clean and cartridges are fresh, it is definitely not because of the water OR the other possibility that water in your area is so bad, that you will need RO only. Is the water you get municipal or coming from a well?

anyone here using LG water purifier?

just curious if the filter replacement can be bought outside aside from going back to LG.. and if yes how much?

was thinking to go for outright payment given there's only 2 ppl in my household

So far can only buy direct from LG ya, prices as below



If compare rental 7 yrs and outright purchase, rental will be more expensive by RM500, but at the same time the warranty is also extended by another 5 yrs, filter package above only covers filters and not warranty.

Hi bro, LG puricare water filter can only subscribe from LG or agent. Per year is RM320.

Anyone installed Bacfree Just Tap undersink water filter? How is it working out for you?

That ceramic new one from UK? Ceramic may work for England, where tap water is already super clean. There is no reason to have ceramic in Malaysia, it is outdated tech with many downsides, especially for relatively dirty water. In UK they still insist on using this, maybe because they have production facilities for it and do not want to retire them, but the whole world had long time moved on to UF membranes and other tech, that offer better filtration, a lot more consistency and much larger surface area. And the price for it is neither cheap. Any specific reason why you are considering it? 1 year warranty, 1 stage filtration with "layers"... Not saying it all because I am a seller of a different undersink systems, but I believe this is actually a very poor price-performance offer with very little carbon and first layer being the 0.2 micron ceramic is a recipe for "always clogged, smells bad" filter.

I am not a filter expert. I guess ceramic's advantage is its outer surface can be scrubbed clean and reused several times; i.e. eco & pocket friendly.

As for the price, it can vary a lot, ranging from RM129 for Doulton to RM8 for a little known brand?.

I remember causing more harm to the filter when cleaning it while my parents used it before as a prefilter back then with our Lux Appliances Water Purifier in the 90s.

Overtightening it by hand can cause it to break as well, eventually we stopped using the water purifier and was scrapped somewhere in the late 2000s.

Problem with ceramic is 0.2 micron is nominal, VERY nominal. It is true for most filters, that when they tell you 0.2 it is 0.2 average, meaning there are some pores that are 0.3 and some 0.1. With ceramic it is that some pores are 20 and others are 0.02 (this whole statement is oversimplification, but you get the point), that is because of the manufacturing process. In fact, they probably don't even know what are the hole sizes, they just assume it is 0.2 micron.

It gets clogged really fast normally, you can technically scrub off the surface, but in reality, to actually open most holes you need to sand paper it. Imagine, you have a surface with tiny tiny holes that you are scrubbing with a huge (compared to the hole) object, you just clean the surface and not the holes itself. So in fact, you are actually pushing the dirt IN the holes, making every next scrubbing less and less effective and actually doing more harm than good.

Now, in theory it may work ok if your water is already rather clean and all you are doing is getting rid of chlorine smell and some occasional dirt. This could be the case for UK, but not Malaysia. You need better filtration here, with more carbon too, IMO.

I agree ceramic is fragile and requires careful handling. ;-) However, I haven't broken any in 21 years - touch wood!

To prevent the ceramic from clogging too fast, it is pre-filtered by a 5 um PP filter.
I find scrubbing the ceramic surface sufficient to restore water flow. When scrubbing becomes less effective over time, then it is time to replace the ceramic - that typically happens after ~3y. So, it is good for both environment & wallet :-). However, if UF can offer the same cost effectiveness, I am willing to switch.

The ceramic does NOT rid chlorine. A carbon filter is required for Cl removal, but a new carbon filter will initially leak carbon powder. So, in an RO system, a ceramic filter in the no. 3 position can prevent the carbon powder from fouling the expensive RO membrane.

I think the concern is even though ceramic filters can be scrubbed, over time u push the dirt into its pores deeper and deeper, it either results in clogged filter or contamination inside the filter itself, compromising water quality

LG filters are Carbon and UF, no scrubbing required, just use and throw

1 year filter cost RM320 for 2 carbon filters and 1 UF filter, is that cost effective enuf for u to consider?

Inside that ceramic you have a carbon layer, so it can't last any longer than 1 year. we are talking about Bacfree model, and as I can see it is not protected by a pre filter in their system either. This is why I am saying, for 12000+RM you are getting very very little. Ceramic itself in some combinations can be used, but why if nowadays it can be replaced by say electroadhision which will be a lot more predictable and remove a lot more contaminants and doesn't clog at all.
