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)

googled, cant find anything on this brand. should be +- the same as other membrane filters.
