Even if it is made in China with same NSF certified standards but save RM200, I will buy China made. Just like I buy huawei phone or iPad.
I think confidence level of people buying China made products has improved tremendously, harping on US made or EU made to sell at the premium price may not be a selling point nowadays.

Yes, I would totally agree with you when talking about anything that has nothing to do with food or beverage. Let's put it the other way. If it cannot affect my health or safety, then I will buy Chinese. But if the price difference is only say 10% I'd still choose the one made outside of China

But I worked in China for too long and I know that standards are not respected. For example, we were trying to manufacture RO tank membranes in China. Our main issue was variance in raw materials. We managed to get them NSF certified, but then, doing our own tests on bladders from different batches, we concluded that it does not conform most of the time.

So we left China and opened a factory in Mexico, slightly more expensive, but never had quality issues since.

I personally trust Taiwan, but that's just me.

Maybe good idea is to offer both and let people choose.

Yes, the water tank was originally installed by the developer. I couldn't change it before of the limited space.

The water got bad smell

GE Pentair POE looks like this.



While the internal filter for drinking quality like the following link:-

What you said is true. Install for the entire house doesnt make sense hence think sand filter good enough if installed at the main and easier for maintenance / backwash I suppose. While drinking water go for premium ones. Too bad rm weak otherwise 3M no need hassle to search and research further.

Got bombard by the local sales team when approached them during the exhibition. Found out little bit more about ultra filtration. They recommend UF install at main intake but as you said not making sense. For washing and flushing toilet also 0.5micron or lower for what which is excessive and insane. Hope I am wrong, looks more like marketing gimmick for the rich and ignorant. When asked more about certification and details on the filters many will not tell the full stories where the source. UF will require daily flushing so lot of wastage and maintenance. So total easily cost 3.5k including timer to install UF for a terraced house which does not come with NSF certification which I think excessive in terms of cost, design, water quality etc etc.

UF, RO or membrane are always waste of water, daily flushing is insane.
POE filter sand media is good enough, easy maintenance and long lasting.

You may need check with your neighbor do they have similar issue? If have probably need ask PBA to check d.

Hi guys, can anyone recommend a good brand for external and internal water filters ? What’s everyone’s thoughts on GE external filters ? Currently using Diamond in my old home , but this was installed many many years ago

can anyone recommend a good countertop water filter (hidden beneath the sink also can, open to suggestion), for my rental apartment.

Correct.

RO is never suitable for drinking. Wonder why so many RO drinking machine out there?

UF install at main intake to the house where many vendors are promoting right now is insane. Only for rich and ignorant sorry be blant. Kena bombard by too much sales talk bit gila liau Pls dont advise pangsai pun use UF quality punya water ya. Still sane not gila yet ...

Ok friends, I had PM conversation with few people, and it seems like people prefer outdoor filters. Well, let me add my 2 cents once again.

Outdoor filters are not such a good idea most of the time. There are 2 reasons for that:

1. You filter ALL the water now. You're now flushing toilets and mopping floors with filtered water. Depending on how much water you use, you may be wasting a lot of filter resources.

2. Your pipes and tank inside house are not perfect. May contain rush, lead, dirt, bacteria, dead lizards etc.

So making pure drinking water outside doesn't make sense at all, but if you ABSOLUTELY want outside filter, then this is what you can do.

1. 5 micron pleated polyester sediment filter. You just buy 20"BB (black/blue) industry standard housing and you add quality, industry standard pleated filter. A good US made one will be washable and should last you 2 or even 3 years (take it out, inspect, if looks ok, wash and put back). This will remove particles, rust, iron, pretty much everything above 5 micron with very low pressure drop.

2. I would stop on #1, but if your water has way too much chlorine in it and smells horribly even to take a shower, then keep on reading. Second filter is radial flow granulated carbon. Will last about 2 years, will take out most of chlorine, bad smell and taste. And, because of radial flow, you will not experience large pressure drop. Now you can take shower with no chlorine, rust and all other nasty stuff.

Now, to the cost. These things are more expensive, this is why it's extremely important to use industry standard components. Again, same logic, you do not want to depend on one manufacturer, who may go out of business or raise the price because "bro, Ringgit is low nowadays".

Now, how much it SHOULD cost

- A quality 20"BB housing with pressure release should cost you more or less 400RM and it will last lifetime.

- US made, quality sediment filter will cost roughly 250RM (remember, it lasts 2 or even 3 years and is washable)

- Good granular carbon radial flow filter of 20" size is expensive, close to 600RM. But this is really optional. Remember, you will need another housing for it.

I'd say most people should be ok with just sediment filter package for 650-700RM. And guess what, this is what big brands are selling too, but for 1400RM and more. Don't believe me? Check 3M AP902 filter "Removes sediments, partciulate, sand and rust down to 5 microns to provide cleaner water right from the point-of-entry for whole house water usage." Yep, that's it for 1400RM a filter that's made who knows where, just with a big brand name on it. And replacement interval once a year.

Do not get fooled by salesman and big brands

is this a DIY method?
what is the BB housing? any pics? would love to see your own design.
thanks

Bought this week, will replace my mom membrane filter. Membrane not been change for almost 7 years and the pvc angle valve been leaking, so decide must as well change it smaller unit. Another DIY weekend


Attached thumbnail(s)

You can DIY, can hire a plumber to install.

Here is the picture of standard 20" BB housing with pressure release valve. You see them outside of some houses. It can take standard filter from any well known brand and if any part of it breaks, many quality manufacturers sell replacements. Your local plumber can easily install one.

Put a quality, US made, polyester pleated 5 micron filter inside and it will outperform any 3M or GE or whatever other overpriced filter.

If you haven't changed membrane for 7 years and still have some flow, means that this membrane doesn't filter anything.

In our water, 5 micron will cause a noticeable pressure drop in about 6 months...

Got do back wash.

i got this transparent poly plastic housing sold quite cheaply in tesco or even in ace.
but i have one doubt of this filter.

the filter inserted into this housing right but it just dropped to the bottom of the housing. Im sure the top part of this filter will have a top gap not filtered. I mean those dirts or green algae will get suck and trapped onto the cotton or fabrics but the top part where the water flows into the inlet will still carry this dirt to the drinking pipe in the end right?

I been exchanging this filter for sometimes and im just curious on how the system really trapped this dirts 100%. I still don't have the confidence of the filter trapping all the dirts and bacteria in 100%.

Im not sure about how 3M design looks like because it seem close.

Valuable info
Can you comment on the below POE filter. The design for the built-in back wash is very interesting, minimise the requirement of control valves and unsightly messy bypass piping.
Affordably priced at RM468 and replacement cartridge @ RM48.


Nice. Please share the picture after installation. Want to see if this filter can really reduce the ugly piping and valves.

Those standard 10" pp filter housing shouldn't have gap. It will fit a pp cartridge properly. If you want to be sure, open the filter top and check if there is a ring shape mark on the the top of the pp cartridge. Of yes, your housing is secured properly.
For green algae prevention, use a black poly bag to cover up the filter.
For extra clean water at POE, you can install double filters in series.
As for confidence level, buy only NSF certified POU filter to boost your confidence.

this backwash filter system might be too small, if the house have larger family , i think if u fix one will not be enough, u may have to do more backwash more frequent.

my house one is using the Rocket by delcol with valve but u don't need to do a lot of time backwash. i think here's the main difference.

Haha, I am amateur plumber, cannot do so nice ler.
