For PoU ? 10" x 2.5" is good enough. Cartridge also cheap and easy to get. You can diy a 3-stage filter housing for around RM100+ like mine here https://forum.lowyat.net/index.php?showtopi...post&p=88081533
You can go to any water filter shop and ask the shop to assemble it for you on the spot. You pay only the cost of the parts.

After you got the housing ready, you can then ask hestati where you can buy a good quality sediment filter for 1st stage, sub-micron for 2nd and Carbon for 3rd stage.

Mine is not for drinking. Drinking will be using other system. Mine is just to filter out initial stage, acting like a POE. Is 10" x 2.5" sufficient for the whole condo? If it is not sufficient, does it mean the consequences will be I have to change the cartridge more often only? Cause I don't think I have space for 20" x 4.5" now that I think about it.

Last but not least, does the housing matters? As in any capalang housing will do is it? Most importantly is good quality filter correct?

Housing is VERY important for drinking water. For POE not so much. For drinking, better be NSF and from good manufacturer/country. The problem with cheap housing is plastic leaching and it could be very bad, especially since leaching increases significantly with temperature, and Malaysia is not a cold country, our water temperature is often near 30 degrees and it will be sitting in this housing, sometimes overnight! But since good POU will filter plastic, POE housing is not so critical.

Yes, you need at least 4.5" by 10" for POE. 4.5 by 20" is hard to fit.

So yes, if you find local 4.5" by 10" now, set up 2 in a row with any filters, then can change for better filters. And yes, if you do not use carbon, can do 20 micron+5 micron sediment in the future.

Why not use 20 inch by 2.5 inch. I find this common enough in the shop I when too.

Okay thanks again for the detailed explanation. So my mission now is to find a 4.5" by 10" housing and filter first. Then in the near future when you carry good quality filter then can get it from you correct?

On the side note, will this setup affect water pressure? If yes, will it be noticeable or barely? Thanks.

for condominium how to install POE ? even management allow to , got sufficient space ?

That's why I am installing small one only. Can install at yard area, management usually won't allow to install at main pipe room.

Anyway, yesterday went to ACE hardware and saw only this two housing available. Is this good enough?

install at yard, the one come from yard is the main pipe ? ...need to hack the wall ? must be done by professional ?

It has pressure release button and metal inserts, good buy.
Buy two units for 2-stage filtering, put normal pp cartridge in the 1st stage and good quality 5 micron in the 2nd. If water pressure effected too much, just use one housing.

What is the purpose of the metal inserts?

How can one prevent mold from growing in the housing if put it under the sun? I have seen it a lot in some houses.

It's not so much about pressure drop, since it's quite hard to measure theoretically and it can be boosted by a relatively inexpensive pump. It's about flow rate reduction. Sediment are rated at 55 liters/minute. Carbon is slightly different. It's usually rated at 12L per minute. (all for size 4.5" times 10"). Average shower takes 7 lpm. If you take 4.5" by 20" then flow is almost 30L per minute. This is what I meant when saying if you often have 2 people taking shower at the same time you may not have enough water. If it's a condo where only 1 person showers at a time, 4.5" by 10" is enough.

However, I do understand that space is an issue for 4.5 by 20". In that case, solution is to have 2 carbon filters in parallel.

Will a condo manager allow all that without an issue?

What is the size of your pipes (3/8 or 1"). I may have housings for you from Taiwan.

In my yard yes, but better if you check with your condo management. Need to hack the wall. Plumber will do it for a fee. See picture attached below for sample.

I assume the red button is pressure release and the the metal in and out point is the inserts right? Good buy as in either one of them will do? Just a slight price different. Hopefully won't affect pressure too much. Will post the result again once I've done it.

Your explanation is technical and I still find it hard to understand. I mean in layman term will you be able to feel the water pressure drop dramatically or barely noticeable? In my case, since it is a condo, installing a booster pump is against the rules and it might affect the main pump as well as far as I know.

I know that 4.5" by 10" is better but where do I get it? And the cartridges as well.

Should is be 2 carbon filter or 5 micron + pp cartridge? I am confused.

Attached is the picture of my condo where someone installed a heater. In my case, I will be doing the exact same thing except mine is a filter. Correct?

Metal inserts is to protect the plastic threads from stripping by the metal pipe thread.
To prevent green mold forming, use a black planter poly bag to cover the transparent housing.

Sorry if it's complicated, will try easier. Yes, with carbon you will feel pressure drop. With just sediment, no. Do you need all the pressure you have at home? Most probably not.

The possible combinations of filters are: 1) 5 micron PP + carbon 2) 20 micron PP + 5 micron PP. No point for 2 carbon for POE system.

Please let me know if your pipes are 1" or 3/4", I will find 4.5" by 10" housings for you with Pentek filters (good filters, not made in USA, but very reputable company). With 2.5" by 10" I'm really concerned that pressure drop (flow drop) will be too much even for small condo

No sorry bro you helped a lot

I actually need all the pressure that I have at the moment as the pressure is not great at all.

I think I can try both of the combination as in I buy all 3 filter and try if the carbon filter doesn't affect much then the first combination will be better, correct?

I am checking with my management about the pipping size. Will prefer to get the housings and Pentek filters from you and save some hassle.

Was told that POE should not have carbon so that water in d tank has chlorine to 'protect' it, no?

Yes. The filter in the picture has both features. There are 10" housing in the market without pressure release and metal inserts, so please take note. If you can get 10 x 4.5" housing, better still.

Got the confirmation from management. My pipes are 1" in size.

Ok,

I will send you a PM.

BTW, if you cannot have pressure drop, then do not use carbon. Carbon will drop pressure unfortunately, there is no magic

got ready make?
