It has better flowrate compared to the normal hollow fibre and does not clogged up easily, hence longer life span

aiks, all these chlorine and PRECIPITATE so confusing, like attending science class now. Cut the story short, just snap a video to prove it, ezier than all these confusing scientific terms.

From what i guess even chlorine does precipitate, when the water comes back, it will push it and mix it back with the water.

thanks for the feedback wiwi and exsakai

Rated Capacity by companies are just estimation not accurate, depending on water quality as well. For your case, you cant install outdoor filter in your condo, hence water is extremely dirty for your old area and normal filters could get clogged fast but with AQUAPHOR aqualen technology and 5 micron pre-filter, it could easily last 1year+ without clogging

Membrane filter yes, must do bypass (possible to get clogged)

Sand filter optional, my own house no bypass as it will look ugly with the extra pipe.

Outdoor is a general filter for whole house, while indoor is just drinking water (much cleaner than outdoor), hence it is recommended to get both

For outdoor, mainly there are two types
1) Membrane
2) Sand

there is other type like Diamond using cloth also but common will be membrane and sand. Each type has their own pros and cos,so it depends on what u really need as an outdoor water filter

Best Water quality and Design = Membrane

Cost effective, low maintenance cost better flow rate = sand


For indoor, if u need hot,cold and warm, then u need to get a water dispenser

water dispenser is just the machine, most water dispenser has built in filters like Coway and Cuckoo.

Aquaphor on the other hand is an under sink water filter (room temperature) but u can add on their water dispenser if u need hot and cold water, for warm, nd to mix manually

instant is smaller, dont think coway is using instant. u can c previous posting, got a forumer post his instant dispenser photo

contact back the filter brand, usually is ard RM 300-400

yes, lots of things not explain the in the catalog. I bliv many of you purchase things and hoping it to be that good but end up not upto expectation.

Similarly, there are customers who bought expensive filters but within 5 - 6 months clog and require replacement regularly, low flow rate and etc etc

Aquaphor has maintained its replacement cartridge price RM 450 for 3 years , no price increase and no promo. Other brands jack up the price and occasionally do promo which is still expensive actually.

most membrane are 0.01 micron (Hollow Fibre Membrane) : Mesh Size = SAME for most brands

I would say more than 90% or may be 100% the membrane filters in Malaysia are actually OEM in CHINA and they are actually +- the same thing with different branding only.

Membrane filters generally have two types
1) Hollow Fibre membrane
2) Multipore membrane or some name it multibore or 7 capillary

Membrane has different types of material, PAN is mainly used in malaysia (cheapest) while some brands do have PVDF and PVC which are better
1) PAN
2) PVDF
3) PVC
4) and etc etc

With this, may be u can google and get detail info about the type and material of the membrane. Hence, u will get a more accurate and neutral answer


NOTE : FLOWRATE and Membrane durability against water pressure in the catalogs could be inaccurate. For example, some brands spec their membrane filter can withstand upto 8 bar of pressure but actually it is referring to the filter casing is able to withstand upto 8 bar while normal PAN - Hollow Fibre can only withsand 3bar + (Not specify in catalog)

Item no4 is 0.5 micron not 0.1
http://www.3m.com/3M/en_US/company-us/all-...91865871&rt=rud


best to change the pipes, but if u cant, then your best option will be 3M DWS2500 or Aquaphor Crystal Eco (0.1 micron filtration). I do not sell 3M products u can check lazada for the pricing, price control, all dealers are selling +- the same price

Actually a 5 micron filtration is sufficient to significantly reduce rust. But to be more effective, more carbon + finer filtration would be able to reduce odor and iron

Master Filters are mainly to reduce sediments and rust only upto 5 micron (for sand type)

However, there are other chemicals and heavy metals in our water that a regular POE cant filter. No filter is able to claim 100% removal of heavy metals and chemicals, most only claim able to REDUCE upto 80-99%, so the difference between a cheap and expensive filter is that the percentage of reduction is higher and also the number of contaminants that it is able to reduce.

A master filter is only able to pro-long the life of the drinking filter (prevent it from clogging fast) and is unable to improve water quality significantly.

these filters are OEM in china with basic cartridge filter

difference between a branded and a cheap filter

From my survey previously on deciding what filter to sell in my shop

1) Reliability
As posted previously, some cheap filters label how good they are but in fact they are not.
Example : Labeled carbon block but it is actually granular carbon only


2) Filtration Quality
Big companies do invest on R & D to produce good filters but OEM brand they just make it cheap, filter cartridge could look big but inside is hollow.

3) After Sales Service
Most OEM products do not have onsite service, warranty is given by the seller not importer. After few years, may be no parts or they discontinued the model, u have to buy new filter

I checked on the brand, claim from korea filter using nano positive filter similar to cuckoo, not some cheap product from CHINA i guess, hence selling at a high price. However, if the price is RM 4999 why not just get cuckoo instead

In KL the brand is OWNER not sure whether it is the same as in east malaysia, it is OEM product hence could have different brands

Yearly replacement cost will be RM 600, if high usage may b 8 to 10 months once. Hence, most purchase it for condo with limited space and low water consumption

sand filter is the lowest maintenance cost. Water filter indoor u r targeting cosway or water dispenser type like coway? if dispenser type, getting an under sink filter and a dispenser separately will save on maintenance cost as well

Eg :
1) Rental Scheme by most brand RM 100 per month, 1 year RM 1200
2) Under sink filter like aquaphor cost RM 450 for yearly replacement, hence u save RM 750 per year but you need to pay RM 2.5k for initial machine cost

Aquaphor definitely is within your budget, with 0.1 micron hollow fibre membrane, carbon block with aqualen and low maintenance cost. Definitely a good buy
