If u install this external 1, it will clog much faster compared to the AP902 and u need to either change or clean it regularly, you are staying in condo or landed? If landed change to our latest membrane multipore to save cost and better filtration 0.01micron, if condo and no place for backwash then your only best option is AP902

Yup, regular UF membrane has several problems explained by our supplier and that is wht we didnt wanna sell it. With the new multibore design, my supplier say it is tested to be more durable. So, we sold 1 to a friend who insisted to get membrane filter due to the design, used for several months without clogging issue and good flowrate, so we started selling it in our shop. Upto date, feedback is very positive
