Gee..! A PoE filter used as PoU prefilter    Too much overkill bro, if it meant for family usage. It can last years and years before it gets clogged but you forgot about the manufacturer's recommended 1 year cartridge replacement interval. It will be such a waste for underutilization. The max you can extend the replacement up to 2 years before the bacterial built up or filter material starts deteriorating. I suggest you move the AP902 out door for whole house filtration and replace a new PoE in the under sink.
As for your concern about people stealing it, I'm of the opinion that petty thief is more interested in your branded snickers then dismantling a water filter. The only value left for the thief is the AP902 filter head as he wouldnt know for sure how long the cartridge has been used.

3M AP902 filter head is only RM32 in Taobao. No need so susah to steal 
Ops! Profiteers is going to curse me for breaking their rice bowl. Sorry profiteers

Now my problem is I don't have much budget for the Outdoor Point Of Entry filter. Spent too much on renovation already.

Could you please recommend a decent good quality outdoor filter to me.

Zheilwane Bro, I did some reading about Ultrafiltration membrane (UF) and found that UF can filter 0.01 micron pure water as clean as RO water or UV treated water but with lower maintenance cost, no water wastage and does not need electricity.  May I know your Crystal ECO main filter K7B which is using hollow fibre membrane, are there same as UF ?

Micro Filtration = 0.1 micron
Ultra Filtration = 0.01 micron
RO Filtration = 0.001 micron

Aquaphor Crystal Eco is using Hollow Fibre membrane categorize as micro filtration (0.1 micron)

Our Multipore POE filter and many other membrane POE filter is the market are categorized as UF (ultrafiltration) 0.01 micron

So common asked question, if we install Multipore Membrane as POE (0.01 micron) wont our POU Aquaphor Eco (0.1micron) become redundant?
Answer is NO. UF can only filter sediments and bacteria down to 0.01 micron, but it is unable to filter VOCs, chemicals and etc etc such as chlorine. For those things, u need a good carbon filter. Even RO system with 0.0001 micron has to be coupled with a few carbon blocks to work properly.
This reminded me of something. NSF standard 42 and 53 do not cover BACTERIA. So, a basic carbon block filter like those RM 500+ do not have bacteria filtration membrane or uv light.

Yes, head only. That's what I was saying, buy AP902 head from Taobao and buy ori cartridge locally at the total cost of RM600 instead of RM1.3K.
2 years ok la, 3 years bacterial built up kaw kaw liao
Thanks for the explanation.
I think to add a final stage UF filter to an existing NSF standard 42/53 certified undersink filter would be a good alternative to UV for those who doesn't have power point under the sink.

The spec is very high. But Russian products can be trusted or not? Please share your views.

Regardless trusted or not, it's out of your budget.
If you are on shoestring budget but need a reliable filter with certified NSF standard, I've already recommended you Culligan IC-EZ-4, USD51.29 sold and fulfilled by Amazon and it does ship to Malaysia. Remember to buy one or two spare cartridge @ USD29.75 and ship together. Find out the shipping cost and share it here.
You can also buy Culligan IC-EZ-1 locally at RM122 @ AceHardware + Spare RC-EZ-4 cartridge @ 11Street for RM249.
You can't use Panasonic because your present set up is undersink whereas Panasonic is a counter top filter.

I have allocated a budget of RM 4000 for Outdoor and Table Top.
